Business Transaction Management – the Next Generation of Business Service Management

Why a New Generation? What’s Wrong with the Old One?

Traditional systems management tools focused on monitoring the health of individual components. Tools like IBM Tivoli, BMC patrol, CA Unicenter, and HP Openview, initially focused on management of servers, services, and resources. In those days, the equation was relatively simple – 100% CPU utilization = bad, 10% CPU utilization = good.

However, the increasing complexity of applications introduced numerous new enterprise application components including databases, connection pools, Web servers, application servers, load balancing routers, and middleware. The business service management (BSM) industry followed shortly after, and began offering tools for database management, network traffic monitoring, application metrics mining, and analyzing Web server access logs.

Each of these business service management tools “speaks” a different language – database management tools speak in “SQL statements,” network traffic tools use “packets,” while systems monitoring report in “CPU and disk usage.”

What Happens When the Application Crashes or Hangs? What Do You Do if a Single Transaction Suffers Slow Response Times?

In comes the war room. To cope with the proliferation of information sources, enterprises developed the notion of the war room. Whenever slow response times or poor performance of critical applications is detected, relevant personnel are grouped together into a room for brainstorming and joint monitoring. This involves a large amount of professionals, since a single transaction may flow through several infrastructure components. For example, a financial transaction will trigger an HTTP request to an Apache Web server installed on top of Red Hat Enterprise Linux, which in turns calls a WebSphere application server on a Windows machine, flowing through an MQSeries queue, eventually querying an Oracle database.

Members of the war room typically include Java and J2EE performance experts, Microsoft Windows system managers, Unix (Linux, Solaris, HP-UX, etc.) system managers, database administrators, network sysadmins, and proxy specialists, just to name a few. This is a lengthy process that can take thousands of man hours to complete.

The New Paradigm – Business Transaction Monitoring

The new generation of systems monitoring and management tools, widely referred to as Business Transaction Management (or BTM), offer a new approach. Instead of monitoring SQL statements, TCP/IP packets, and CPU utilization, Transaction Management tools view everything from an application perspective. In the world of transaction management, an application is considered as a collection of transactions and events, each triggering actions on the infrastructure. The goal is to track every transaction end-to-end and correlate to the information collected from the infrastructure. Such an end-to-end view enables to quickly isolate and troubleshoot the root cause of performance problems and start tuning proactively. This application-centric information base enables a group of professionals working together to speak the same language and focus on facts, rather than guesswork.

According to IDC (Business Transaction Management – Another Step in the Evolution of IT Management), BTM will likely become a core offering of established IT system management vendors, since it can contribute to almost every aspect of IT management – ranging from performance management, SLA management, and capacity planning, to change and configuration management (CMDB).

End-to-End Monitoring of Transactions

End-to-end monitoring solutions should monitor all of the infrastructure’s components, yet some solutions only monitor one part of the bigger picture.

The term “end-to-end” relative to transaction monitoring is very over-used. End-to-end Website monitoring, end-to-end server performance monitoring, end-to-end database monitoring, and end-to-end network performance monitoring. The list can go on and on when, in fact, they only provide monitoring for one small part of the bigger picture, as illustrated below.

What End to End Means to different solutions

Why True End-to-End Transaction Monitoring is Different than Monitoring Server Performance

Monitoring server performance traditionally refers to ensuring that CPU utilization and memory consumption have not reached maximum levels. However, this does not promise true application availability. Traditional end-to-end monitoring tools provide a dashboard that shows the health of each one of the individual components within the data center. But what if someone forgot to re-connect a network cable after maintenance or what if a load balancer was configured incorrectly and is not executing a proper round robin? An alert will indicate that something is wrong with the servers that are still connected when, in fact, the problem is that traffic is simply not being equally distributed. A network performance monitoring solution could be implemented, which would aid by monitoring the usage of the network, but that is not a single end-to-end solution anymore.

What if a runaway process in one server is “bombing” a second server with requests? The server monitoring solution will blame the server that is being bombed by the server which has a runaway process running on it as opposed to indicating the source of the problem.

Real User Monitoring: An End to End Solution?

If you only take the user’s tier into account, real user monitoring could be considered an end-to-end solution for that tier alone. With real user monitoring, you can see both ends of a transaction—hence the claim to provide end-to-end. What about everything in the middle? What action is to be taken when a problem is detected by the end-user experience tool? What if the root of the problem resides within the database or the mainframe? Shouldn’t an end-to-end solution be able to take care of everything, including triage within the data center? Website performance monitoring is important for understanding the quality of service that your customers are receiving and there is a lot of value in that, but an end-to-end solution should also help you find the cause of the problem along with simply reporting its existence.

End to End Transaction Monitoring Tools Deliver

What do the following components have in common: the user’s desktop, a firewall, a proxy, a load balancer, a Web server, an application server, a message broker, a database and a mainframe? The answer is transactions. The only way to provide a true end-to-end solution is by monitoring every transaction from the moment any user clicks any button, and continuing all the way through each tier. Only business transaction management (BTM) solutions can promise that.

Performance monitoring tools that are not showing end-user performance are not focusing on what is most important to the business. Website monitoring tools that send synthetic transactions to the site and check response times are not showing what users are really experiencing. Database monitoring is important, but without knowing the context of that problematic SQL server transaction, resolution can be a shot in the dark.

Transaction Monitoring With BTM

End-to-end solutions must be able to monitor all of the infrastructure’s components. Transaction monitoring solutions do that automatically since they monitor the object that ties all of those different components together—the transactions. BTM solutions enable a drill down that begins from each transaction type that is running on the system and ends with the smallest event that composes a single transaction instance. In this manner, not only are you assured that everything is running smoothly, but when things start to go wrong you can perform immediate triage and resolution.

SharePath—The Most Comprehensive Transaction Monitoring Solution

SharePath by Correlsense is the only single solution on the market today that can provide true end-to-end transaction monitoring. From the moment a user clicks any button in a monitored desktop or Web-based application, SharePath monitors the transaction through the entire infrastructure, through proxies, Web servers, load balancers, application servers, message brokers, databases and mainframes. Learn more.

Transaction Monitoring Software: Jargon Proliferation

This article on the jargon proliferation within the transaction monitoring discipline reviews common phrases used today to describe how to link business and IT.

There are several ways to trace a transaction. Although different approaches to transaction tracing may yield different outcomes, no matter how you do it, you should be able to trace a transaction completely, from end-to-end.

This can be confusing. Why should monitoring for transaction performance mean something different with every approach? The reason is that the rather nascent transaction monitoring software discipline is still in the “early adopter” phase, not unlike Blu-ray vs. HD DVD.

Monitoring for transaction performance is a clear next step for many enterprises, but when it actually comes to putting a transaction monitoring system in place, it is very hard for many IT professionals to understand the value proposition.

Transaction Monitor? Transaction Trace?
Several buzzwords get tossed around these days describing transaction monitoring software. Interestingly, there is often no link whatsoever between the buzzword and the actual technology; vendors that use the same words to describe their products can have completely different offerings at the end of the day, as we reviewed in this article, “Transaction Monitoring – the Four Approaches.”

It is also interesting to see that the words “monitor” and “trace” are synonyms in English, and in fact, it seems as though “transaction monitor” and “transaction trace” are used pretty much interchangeably in the industry. However, when you really think about it, they can mean different things. The only place where it seems that transaction tracing and transaction monitoring have been defined side-by-side is at Doug Mcclure’s blog. Intuitively, you could define transaction tracing as the topology of the transaction (over the different tiers of the infrastructure) and that transaction monitoring includes all of the metrics of that transaction (i.e., events summoned and resource consumption).

Why Monitor Transactions?

Monitoring and tracing transactions is the way to link business and IT.

The “business” is the user initiating transaction activations—clicking on the “add to shopping cart” button or performing a stock trade, for example. The majority of interactions between the user and the UI (be it a Web page or desktop application) create transactions. The business depends on these transactions, and since the business has spent, in most cases, millions of dollars to allow users to perform these transactions, not only should they work, but they should do so within a time that the user is willing to wait. Time is money, after all.

The “IT” is everything the infrastructure does in executing a transaction. A good example is that annoying SQL statement that has just caused the application to hang because it was activated 100,000 times. Without the link, the database administrator is going to have a tough time figuring out how to keep the problem from occurring again. With the link, that single statement is now tied to a specific transaction and user. All the way from the back end, the DBA can understand the business impact of the statements, because she knows exactly what the intent of the user was and how long it took to complete the transaction from end to end.

Transaction Monitoring with SharePath
SharePath links every transaction to all of the events that the transaction invoked within the infrastructure, giving you the power to link your business with your IT and to proactively ensure that each customer is satisfied.

The Top 3 Reasons an Application Hangs

Do you experience application hang problems? If so, read this article to discover the top 3 reasons applications hang and cause slow performance.

If you have been in the IT industry long enough, you probably know this story well. The application works fine, then, suddenly, the application hangs with no apparent reason. You restart the application and it all goes away. A week passes, maybe two, and then the application hangs again. Another restart and you’re back. It doesn’t crash or fail (no crash dump or thread dump)—it just sits there and hangs. No users are being served.

Eventually you decide to just restart every night hoping it will not hang again. It doesn’t matter if you’re using a Tomcat application server, WebSphere, WebLogic, JBoss or whatever — if you have been in the software development business long enough, you must have experienced this problem. This is where application monitoring can help.

Below are the top 3 reasons why an application server hangs:

Reason #1: it’s a database problem.

This may sound strange, but the main reason an application server hangs is not directly related to the application server itself. The location of the symptom is rarely the location of the root cause. The following scenario is quite common:

  • The database is bottlenecked, causing queries to run slower than usual.
  • Requests that used to take 1 second, now take 5 seconds to complete.
  • The average number of concurrent requests slowly increases (due to backlog).
  • The server runs out of threads and the application server hangs.

If you manage to get a thread dump, you’ll just see a bunch of threads waiting and another group that’s actually running. Another possibility is that the number of waiting threads (or queued threads) will gobble up all available memory and, eventually, lead to an OutOfMemory error.

Reason #2: deadlocks.

If it seems that the application server is doing nothing, look for deadlocks. These can be database deadlocks that cause your SQL queries to hang, or seek the update statements. For example, a transaction log that is written to the database for each request may easily hang the entire application if the log table is locked. It can also be a deadlock of the application re-accessing itself. Do you have any HTTP SOAP calls from one application server to another? Also check for shared objects—an operating system file that is written to from multiple threads at once.

Reason #3: run-away thread.

In cases where the application server is indeed to blame, you should look for a run-away thread. These are hard to detect because they hardly show up on logs since they are usually only written when the request has completed. A run-away thread will probably not return until it has already affected the entire application. Therefore, the hanging request will not be written to the log. These ‘runaway’ threads typically include infinite loops in code. For example, a query that should show results that does not include the option of paging between result pages suddenly needs to display a large number of results. The page takes forever to render and clobbers the application server, eventually causing it to hang.

These types of application hangs are extremely difficult to diagnose and detect. The hardest part is isolating the root cause of the problem. If the application server hangs, it doesn’t necessarily mean that the problem resides there. It usually doesn’t. End-to-end transaction management tools, such as SharePath by Correlsense, helps to pinpoint the reasons for an application hang by providing a real-time view into the entire application behavior.

The Evolution of Transaction Management – Part 1

Transaction management has evolved to a fourth generation. Based on a podcast by Doug McClure, this article covers the end-to-end transaction management evolution.

Information technology contributes to business efficiency like nothing else. Managing complex IT systems requires constant innovation; systems management has come a long way since the days of “Big Iron.” The fourth generation of systems management, widely referred to as “end-to-end transaction management,” enables IT to reach levels of maturity and stability like never before.

Mainframe Systems Management – Generation 1

The birth of application performance management tools came with the development of the mainframe Omegamon and Tmon. These tools monitor program names, Customer Information Control System (CICS) jobs and Job Control Language (JCL) tickets. As far as application performance management goes, this was really the first transaction performance management solution where everything was centered on the mainframe.

Client/Server – SQL Management – Generation 2

Next up was the client/server. Back then, the server was essentially the database. The database was the single point of failure, since it became the place where all of the data was stored and SQL queries were everything. If you had a problematic SQL query, then you had a slow transaction.

That is really when the true application performance management market emerged; with companies like Precise and Quest. The first tools for database monitoring utilized the SQL command line to extract system information. These first application performance management vendors built smart agents that collected all of the information all of the time and sometimes it actually worked in production. These application performance management tools had a nice (relative to the time) dashboard and suddenly there were viable tools on the market for optimizing the database. Database administrators finally had something to work with that gave them value. This was around 1997, when Windows 95 was just becoming stable.

J2EE Profilers and the User Experience – Generation 3

G3 is the generation that is currently coming to a close. This generation began with the emergence of Java application servers. Java’s rise within large organizations was seen in 1999-2002, and suddenly many application vendors started working with Java. As they built applications and sold them to enterprises, the number of Java application servers exploded. This phase introduced the need for a Java profiler tool that could manage performance. Java profilers were brought to the market by Wily, BMC and others.

At the same time, with the rise in online computing, it became important to track user experience; your Website was suddenly your business. With the Web so critical to doing business, it was important to make sure it was performing as expected. At the time, running synthetic transactions with Gomez, Mercury Topaz, and others in order to ensure availability was the way to do it.
Alongside the JVM profilers and user experience tools, there were always network probes to ensure the network was working. As TCP/IP became the standard, solutions parsed and sniffed these protocols, parsing network traffic in order to monitor performance.

What Marks the End of 3G Systems Management?

In the last few years, the last two major silos that we have not yet listed, middleware and storage, have had tools developed for them. For example, companies like Onaro (acquired by NetApp) developed tools that extended application performance management into the storage tier and MQSoftware (acquired by BMC) developed tools for Websphere MQ. Today, every silo has its own performance management tool, all with the objective of achieving greater application performance.

All of this activity happened over the past 6-7 years. Every silo was developed on its own and was embraced by the industry. In the past two years, the market become stable; however, we do see new concepts for application servers, and other languages—not just Java-based–and we see a lot of integration. Web services is the new buzz word, which is really just an easy way to do integration (enterprises were doing HTTP-based XML 10 years ago). All of these changes notwithstanding, there are no new silos. There are more of them, but not many different types of silos.

Stability and Maturity = 4G End-to-End Transaction Management

The market has matured to a level where you can deploy end-to-end solutions. If you would have tried to do this a few years ago, you would have run into complications. Currently there is enough stability in new technology as far as enterprise applications are concerned in order to enable the proliferation of end-to-end management. Of course, there is always constant progress in storage and network throughput. These technologies will continue to move forward, but the technology for tracking a transaction is here to stay. TCP/IP will be with us for the next 10-20 years, and HTTP protocols aren’t going to change in the next 5-10 years. While Java will not go away as an application server, there will be new methods for implementing an application server. It will not necessarily be JVM, it could be a new process; however, eventually it’s going to be some sort of process, multi-threaded or not, which will handle the transaction. The overall architecture of the application is going to stay more or less the same: a rich, mixed, and complex topology that is difficult enough to manage as it is. This maturity is exactly what is enabling transaction management to become the fourth generation of IT systems management.

Bringing IT Together

For the moment, forget the buzz words like Business Service Management, Business Transaction Management, Service Level Management and others. What we are talking about is the evolution of IT systems management, which is defined as everything that is needed in order to make the IT data center work. Transaction management will compose 70% of the systems management space. It will be critical (and already is) in ensuring sure that your data center actually works.

A big thanks to Doug McClure of dougmcclure.net for creating an informative podcast with Correlsense CTO Lanir Shacham from which the ideas for this article were taken. Take time to listen to Doug’s podcast, which aims to shed light on the next generation of IT systems management.

Much More Than a SOAP Monitor

This article discusses how SharePath provides immediate visibility into complex SOA transactions–more than just SOAP monitoring.

Imagine the following scenario:

  • An apache server running PHP receives a request for availability of an item.
  • The PHP code uses nusoap to send a SOAP request to a web service hosted on an application server running an IBM WebSphere application server to locate the information.
  • The WebSphere application server receives the SOAP request and sends an SQL statement to an Oracle database.
  • The WebSphere composes a SOAP response and sends it back to the PHP presentation server.
  • The SOAP response is handled and the response page is sent back to the browser.

Using SharePath, you can gain immediate visibility into complex SOA transactions. Only SharePath provides true web services monitoring and SOA monitoring—more than just SOAP monitoring

Overview

The pervasive and growing use of services oriented architectures (SOA) and Web services is testimony to its power and versatility. But the loosely-coupled nature of SOA applications and Web services makes it difficult to monitor transactions, creating a tough challenge when trying to isolate and fix performance issues.

SharePath Solves the SOA and Web Services Monitoring Challenge

SharePath provides a clear look inside any SOA system. It provides not only SOAP monitoring and Web services monitoring, but much more—tracking and tracing transactions from end-to-end.

SOA in Business Systems

Services oriented architectures are emerging trends based on the WSDL, SOAP, and Web services standards. As these types of applications become more pervasive, the need for SOA transaction management and Web services monitoring grows. The need for SOA and SOAP monitoring is not just capturing each SOAP request and response, it is primarily the need to understand the context of each

SOAP message and Web service activation across the entire transaction.

Difficulty in Monitoring SOA

The current generation of systems management and monitoring tools lack the ability to track transactions through service oriented architectures composed of heterogeneous platforms (J2EE, .NET framework, PHP, C++). This challenge makes it difficult to detect, isolate, and solve SOA performance problems when using Web services. No matter how you build your SOA, either through a commercial enterprise service bus (ESB) or an open source ESB such as Apache Tuscany, Apache ServiceMix ESB or a roll-your-own ESB, tracking and monitoring transactions is a critical requirement for any SOA-enabled application. Loosely coupled applications are great when it comes to reuse and agility, but make it exponentially more difficult to isolate and fix performance issues.

SOA monitoring and SOAP monitoring includes the following challenges:

  • SOA environments typically include co-dependency between several applications, infrastructure and components.
  • Web services often each have their own log files and monitoring systems.
  • SOA is by nature heterogeneous, so monitoring transactions across several systems is difficult. Furthermore, SOA systems often rely on a variety of libraries and components such as nusoap for PHP, Microsoft SOAP toolkit, and Apache AXIS, each providing its own separate monitoring solution.

A true SOA monitoring, or Web services monitoring, solution is much more than just SOAP monitoring. A SOAP monitor merely captures the SOAP messages flowing between two tiers. However, the SOAP monitor cannot understand the complete path of the transaction. In order to gain true visibility, a SOAP monitor is not enough. To be effective, a SOA monitoring tool needs to monitor individual transactions across multiple components, technologies and environments during both testing and deployment. Business transaction management tools meet this challenge by providing a complete end-to-end view.

SharePath Provides End-to-End Transaction Performance Management

SharePath monitors entire enterprise applications, from the performance in your customer’s browser, to enterprise application performance, the performance of Web services, and the performance of the databases in the backend.

SharePath for Web services monitoring enables you to:

  • Track and monitor every SOAP message and web services call.
  • View the context of each transaction from end-to-end, in real time, as it passes through various Web services and components.
