There are many ways to set up your Jenkins environment, and depending on the configuration you choose, there are different best practices and options to optimize your environment. In this blog, I’m going to focus on Jenkins Health Advisor by CloudBees as a way to fine-tune your environment. It’s a free tool that can help administrators understand and manage their Jenkins controller. If you’re a CloudBees customer, the tool automatically comes with CloudBees CI. However, it’s also available as a free open source tool to anyone who uses Jenkins. The Jenkins Health Advisor tool can make your life easier because it can arm you with the information you need to keep your Jenkins environment running smoothly.

A Bit of Background

The CloudBees support team originally created the tool as a way to help customers troubleshoot Jenkins issues. With the tool, our support engineers could gather information from a customer’s Jenkins controller about the configuration of the controller and agents, the operating system, stats from web requests, and the like. Our tech support teams used this data to help customers pinpoint problems, such as security vulnerabilities, performance problems, and plugin version issues. Very quickly, our support tooling team saw the bigger-picture benefits of the diagnostic tool as an opportunity for people to proactively manage their controller. With that bit of background, let’s dive into the Jenkins Health Advisor tool so you understand how it can help you.

The Problem—Lack of Visibility into Controller Environment

Because of the open source nature of Jenkins and the vast array of plugins that you can deploy in your Jenkins installation, downstream code changes to plugins and corresponding dependencies can inadvertently impact your environment, which slows productivity, causes confusion, and impacts the quality of your software delivery. When problems arise, Jenkins administrators need to quickly pinpoint the root cause of an issue, and that can be quite a challenge.

The Solution—Jenkins Health Advisor by CloudBees

When an issue arises, you need razor-sharp insight to help you quickly sift through lines upon lines of data about your Jenkins controller and your plugins to identify the problem. And that’s exactly what Jenkins Health Advisor does. It gives you specific information about potential problems in your environment so you can resolve issues as quickly as possible.

When you first install the Jenkins Health Advisor tool in your environment, you’ll receive a report that lists everything it detects in your system. You’ll then receive report emails only when something changes that could impact your environment or when the tool identifies an issue that could be problematic. If there are no issues in your environment, you don’t receive an email. It’s really that simple.

The Power Is in the Insight…and the CloudBees Support

Okay, so let’s explain how Jenkins Health Advisor uses data to help you optimize your environment. The tool actually generates a support bundle every 24 hours. We don’t want to bog down your email inbox with redundant reports emails, so we don’t send every report to you—only the reports that indicate an issue with your environment. However, CloudBees receives every support bundle from every user. We are constantly monitoring all of this active Jenkins controller data with external Jenkins and open source data about known issues, plugin updates, security vulnerabilities, and so on. If the Jenkins Health Advisor tool identifies an issue that could impact your system, you’ll receive an email so you can proactively address the problem. At the same time, CloudBees engineering teams are continually working to enhance the detection capabilities of the Jenkins Health Advisor tool, so you can work as proactively as possible to manage your environment.

The emails you receive identify potential problems, and they also include supporting information to help you resolve issues, with links to solutions and recommended resolutions as well as articles to understand the problem.

Helpful Tips to Gain Value from Jenkins Health Advisor

  • Improve Troubleshooting

    If you need to troubleshoot a particular issue, you can manually generate a support bundle to give you point-in-time information on your environment. You can filter the support bundle data on different system parameters, like the build queue, dump agent export tables, and garbage collection logs, so you get the specific information you need.

  • Generate Anonymized System Data

    At any time, you can change the settings on your tool to anonymize the data in your support bundles. You may want to do this if you don’t want to share sensitive project data with CloudBees. Our support and engineering teams can still gain valuable insight from your generic system data. This is also a helpful feature if you need to share system data with a partner or vendor, and you don’t want to share project or personnel data.

  • Jenkins Health Advisor Tool Updates and Support

    As we mentioned above, the CloudBees support tooling team is constantly working to enhance the tool. To ensure it’s always as current as possible, we release updates to the tool every two weeks. Usually, these updates won’t impact your Jenkins environment. However, if there are changes to the tool that might affect your system, you’ll receive a notification email so there are no surprises. And, if you need help with the Jenkins Health Advisor tool, our support engineers are available to answer your questions.
