Transaction Tracing for Performance Bottleneck Detection | @DevOpsSummit #DevOps

Transaction Tracing refers to end-to-end request code execution

Transaction Tracing for Performance Bottleneck Detection
by Mick Emmett

When you’re building a monitoring solution or evaluate existing ones, what do you look for? Probably these four core aspects of functionality:

  1. Collection and display of metrics
  2. Alerting based on metric values and anomalies
  3. Collection and display of server and application logs and other types of events
  4. Alerting based on log patterns and metrics extracted from logs

But there is really one more juicy piece of functionality one should look for:

  • Distributed Transaction Tracing

What’s more, as a nice side-effect of Transaction Tracing in SPM you will also get:

  • Your app’s Request Throughput, Response Latency, plus Error & Exception Rates
  • AppMap, which which how various components in your infrastructure communicate with each other

What is Distributed Transaction Tracing?
[Note: If you know what Transaction Tracing is and what the benefits are, you can jump right to the bottom of this post to see how to enable it.]

When we say transaction in this context we are not referring to database transactions.  In the context of Application Performance Monitoring, Transaction Tracing refers to end-to-end request code execution that can span multiple applications running and multiple servers.

For example, when you shop on Amazon.com and search for a product there, your search action starts a request transaction that can be traced though various layers of Amazon.com’s application and server infrastructure, all the way down to the database and back.  That is what SPM’s Transaction Tracing can do, too, for your own applications and servers.

Where Transaction Tracing fits in
Let’s start with a simple diagram. The little “SPM agent” box is the embedded agent responsible for tracing all transactions and capturing information about them.  Everything in orange and all red arrows would be traced by SPM’s agent, even as transactions go across networks and hop from server to server – hence Distributed Transaction Tracing.

Now, let’s quickly look at a slightly more complex diagram:

TT_3

Here we also see an external HTTP service (e.g. third party REST API) our application talks to via HTTP.  That, too, is captured, along with all orange components and red arrows.  We can also see Service1 has multiple internal classes and methods.  SPM traces execution deep inside your code, too, so it can tell you which methods in which classes are slow.

How / Why is Transaction Tracing useful?
In short, Transaction Tracing is great for:

  • Pinpointing root causes of poor application performance, so you can fix ‘em and make your users happy and your mom and dad proud!
  • Finding the slowest parts of your application, so you can speed up troubleshooting and get the most return for your development time

Have a look at the following chart and you’ll be able to relate.  It shows the response time for one of our real components deployed in production.  You can see how response time improved at one point, right?

We enabled Transaction Tracing to find and fix a bottleneck in our own code.  In short, we went from the 99th percentile response time for one of the components being 1-3 seconds to about 0.15-0.30 seconds.  That’s about 10x faster!

Where & How to enable Transaction Tracing
If you’ve been using SPM you are likely to use one of its integrations for monitoring your backend infrastructure – Apache Spark, Solr, Storm, Elasticsearch, Hadoop, Cassandra, Kafka, that sort of backend stuff. As you can see from the above diagrams, transaction tracing starts closer to the front-end — in the tier that runs client applications which talk to backend and remote services, as well as data stores like Solr, Elasticsearch, Cassandra, HBase, MySQL, and data processing frameworks like Apache Spark or Kafka, or even Hadoop.

In other words, to get the full benefit of Transaction Tracing you need to do the following:

  • If your webapps run in Tomcat create a new SPM App for Tomcat.  If you use Jetty, Glassfish, JBoss, or some other Java container simply create an SPM App for JVM.
  • Add SPM Agent to your webapp tier (e.g. to your webapps running in Tomcat, Jetty, Glassfish, JBoss, and similar Java containers).  Use the Embedded (aka javaagent), not Standalone mode.
  • Enable Transaction Tracing in SPM Agent configs in all your tiers

And that’s it.  Once you have Transaction Tracing enabled look under the new Transactions tab in SPM:

TT_1a

In the coming days, we’ll be publishing more information about Transaction Tracing in SPM, including how-tos, additional functionality derived from Transaction Tracing, etc.

In the meantime, here are the key points:

  • Transaction Tracing does not require you to modify any source code – the instrumentation is done automatically, at the JVM bytecode level
  • Transaction Tracing is currently available for Java and Scala apps running inside the JVM
  • Transaction Tracing is exposed via the new “Transactions” report (tab) on the left side in the UI.  That said, the key bit to understand is that Transaction Tracing is really means for finding bottlenecks in your applications and how they talk to backend services, frameworks, and external services, not in the backend applications your applications connect to. See the diagram further above.
  • We support deep insight into specific technologies listed in SPM Transaction Tracing documentation
  • You’ll want to grab the latest version of the SPM client (it has some optimizations, too!)
  • You’ll need to use the SPM monitor in the embedded (aka javaagent) mode, not standalone
  • To add Transaction Tracing to your own custom apps you can easily create a custom pointcut

@DevOpsSummit Stories
While DevOps most critically and famously fosters collaboration, communication, and integration through cultural change, culture is more of an output than an input. In order to actively drive cultural evolution, organizations must make substantial organizational and process changes, and adopt new technologies, to encourage a DevOps culture. Moderated by Andi Mann, panelists discussed how to balance these three pillars of DevOps, where to focus attention (and resources), where organizations might slip up with the wrong focus, how to manage change and risk in all three areas, what is possible and what is not, where to start, and especially how new structures, processes, and technologies can help drive a new DevOps culture.
After more than five years of DevOps, definitions are evolving, boundaries are expanding, ‘unicorns’ are no longer rare, enterprises are on board, and pundits are moving on. Can we now look at an evolution of DevOps? Should we? Is the foundation of DevOps ‘done’, or is there still too much left to do? What is mature, and what is still missing? What does the next 5 years of DevOps look like? In this Power Panel at DevOps Summit, moderated by DevOps Summit Conference Chair Andi Mann, panelists looked back at what DevOps has become, and forward at what it might create next.
For organizations that have amassed large sums of software complexity, taking a microservices approach is the first step toward DevOps and continuous improvement / development. Integrating system-level analysis with microservices makes it easier to change and add functionality to applications at any time without the increase of risk. Before you start big transformation projects or a cloud migration, make sure these changes won’t take down your entire organization.

In the world of DevOps there are ‘known good practices’ – aka ‘patterns’ – and ‘known bad practices’ – aka ‘anti-patterns.' Many of these patterns and anti-patterns have been developed from real world experience, especially by the early adopters of DevOps theory; but many are more feasible in theory than in practice, especially for more recent entrants to the DevOps scene. In this power panel at @DevOpsSummit at 18th Cloud Expo, moderated by DevOps Conference Chair Andi Mann, panelists discussed the patterns and anti-patterns of DevOps, and what it means to ‘do the right thing’ in a DevOps way, but in the real world.

Both SaaS vendors and SaaS buyers are going “all-in” to hyperscale IaaS platforms such as AWS, which is disrupting the SaaS value proposition. Why should the enterprise SaaS consumer pay for the SaaS service if their data is resident in adjacent AWS S3 buckets? If both SaaS sellers and buyers are using the same cloud tools, automation and pay-per-transaction model offered by IaaS platforms, then why not host the “shrink-wrapped” software in the customers’ cloud? Further, serverless computing, cloud marketplaces and DevOps are changing the economics of hosting and delivering software.
"When we talk about cloud without compromise what we're talking about is that when people think about 'I need the flexibility of the cloud' - it's the ability to create applications and run them in a cloud environment that's far more flexible,” explained Matthew Finnie, CTO of Interoute, in this SYS-CON.tv interview at 20th Cloud Expo, held June 6-8, 2017, at the Javits Center in New York City, NY.
Wooed by the promise of faster innovation, lower TCO, and greater agility, businesses of every shape and size have embraced the cloud at every layer of the IT stack – from apps to file sharing to infrastructure. The typical organization currently uses more than a dozen sanctioned cloud apps and will shift more than half of all workloads to the cloud by 2018. Such cloud investments have delivered measurable benefits. But they’ve also resulted in some unintended side-effects: complexity and risk. End users now struggle to navigate multiple environments with varying degrees of performance. Companies are unclear on the security of their data and network access. And IT squads are overwhelmed trying to monitor and manage it all.
It is ironic, but perhaps not unexpected, that many organizations who want the benefits of using an Agile approach to deliver software use a waterfall approach to adopting Agile practices: they form plans, they set milestones, and they measure progress by how many teams they have engaged. Old habits die hard, but like most waterfall software projects, most waterfall-style Agile adoption efforts fail to produce the results desired. The problem is that to get the results they want, they have to change their culture and cultures are very hard to change. To paraphrase Peter Drucker, "culture eats Agile for breakfast." Successful approaches are opportunistic and leverage the power of self-organization to achieve lasting change.
In 2014, Amazon announced a new form of compute called Lambda. We didn't know it at the time, but this represented a fundamental shift in what we expect from cloud computing. Now, all of the major cloud computing vendors want to take part in this disruptive technology. In his session at 20th Cloud Expo, Doug Vanderweide, an instructor at Linux Academy, discussed why major players like AWS, Microsoft Azure, IBM Bluemix, and Google Cloud Platform are all trying to sidestep VMs and containers with heavy investments in serverless computing, when most of the industry has its eyes on Docker and containers.
