Support Core Plugin
The plugin provides the basic infrastructure for generating "bundles" of support information within Jenkins.
There are three ways of generating bundles:
- Automatic bundles, these get saved in $JENKINS_HOME/support once per hour starting 15 seconds after Jenkins starts the plugin (i.e. this may still be generated even if Jenkins will not fully start). The automatic bundles are retained using an exponential aging strategy, so you should have a bunch of them over the entire lifetime once the plugin has been installed.
- On demand bundles:
- You can generate them from the root "Support" action, using the User Interface ; or
- By using the CLI Command. For the association documentation, please refer to
As part of the support bundle if the About Jenkins option is checked then you will receive a docker file in the bundle also. The docker file contains the current version of Jenkins, along with a wget operation to download all of the plugins on the Jenkins master. This creates a similar environment for testing or reproducing bugs.
First build the image:
docker build -f Dockerfile
then run the docker image
docker run -d -p 8080:80
This should create a new Jenkins master with the same version, and the same plugins and versions all bundled.
Third party support providers
Various companies and organizations provide commercial support for Jenkins. They can provide additional content and branding to the support action. The following lists the known third party support providers (in date order) and the links to their support provider plugin.
Support bundles corrupt through the UI
The most common situation for this to happen is when the About Jenkins option is enabled.
Meanwhile, the support bundle is getting generated it looks like the generation process is stuck as the downloaded size stays at the same point for a long time. To diagnosis this issue the best is to take a threadDump when in the moment where it is stuck and check the Jenkins logs.
If a stacktrace like the one below appears
and the Jenkins logs are populated with
Then, surely the problem is that you are hitting the Idle timeout in the load balancer and this makes the connection betweek the ELB and your broweser to drop. To workaround this problem you can:
- Increase the Idle timeout in the load balancer
- Not include About Jenkins section
- Reduce the number of builds in the system
Support Bundle Anonymization
Beginning in version 2.48, this plugin now allows for automated
ContentFilter extensions to enable anonymizing of various data. By enabling this feature, the default set of filters will anonymize agent names, agent computer names, agent labels, view names (aka folders), job names, usernames, and IP addresses (both IPv4 and IPv6). These data are mapped to randomly generated fake names which are saved to Jenkins master. A Jenkins administrator can view these mappings by going to Manage Jenkins › Support Bundle Anonymization. All files written to the support bundle by this and all extensions of this plugin will replace all instances of the original values with their anonymized counterpart. Note that the Stop Words list on that page shows which terms are ignored when filtering names (case-insensitive full match).
Anonymization filters only apply to text files. It cannot handle non-Jenkins URLs, custom proprietary Jenkins plugin names, and exceptions quoting invalid Groovy code in a Jenkins pipeline. The active plugins, disabled plugins, failed plugins, and
Dockerfile reports are not anonymized due to several Jenkins plugins and other Java libraries using version numbers that are indistinguishable from IP addresses. These reports are in the files
docker/Dockerfile. These files should all be manually reviewed if you do not wish to disclose the names of custom proprietary plugins.

slow-requestswas missing stack traces.
Version 2.17 (Oct 10 2014)
- Capture past slave launch logs, not just the current session (JENKINS-25108)
Version 2.16 (Oct 8 2014)
- Prevent slow-request files from going over 2MB in size.
Version 2.15 (Sept 25 2014)
- Added some NPE safety against cloud implementations that return malformed slave descriptions
- Slow request content was not properly displaying stack trace elements
- Resolve file descriptor symlinks
Version 2.14 (Sept 5 2014)
- Better summarize Item’s of all kinds. (JENKINS-22609)
- Checking for slow requests threw an exception on an non-locked thread. (JENKINS-24567)
Version 2.13 (Aug 26 2014)
- Workaround for JENKINS-24358 deadlock.
- Record the query string in slow request logs.
- Add lock owner thread info to slow request logs.
- Note the current thread name at each slow request sample.
- Omit empty
Version 2.12 (Jul 22 2014)
- Make the SlowRequestChecker timings configurable and only collect thread dumps if there are slow requests (JENKINS-23904)
Version 2.11 (Jul 8 2014)
- When sending log files remotely, GZip the content to reduce bandwidth requirements
Version 2.10 (Jul 8 2014)
- The remote node logs were not being transferred once the log file grew above a certain undetermined critical size due to GC pressure removing an exported remoting reference from the slave's JVM.
Version 2.9 (Jul 8 2014)
- When there are many remote nodes, the serial fetching of logs in 2.8 can cause bundle generation to take an excessive amount of time. Now the log fetching is performed in parallel.
Version 2.8 (Jul 8 2014)
- Add caching of slave log files with append-based fetch for when the cache contains partial content. Should significantly reduce the support bundle generation load unless slave logs are generating a lot of content rapidly.
Version 2.7 (Jul 4 2014)
- Make some of the remote operations asynchronous and time bounded in order to reduce the impact of periodic support bundle generation and speed up bundle generation in general.
- The only default content that retains synchronous remoting I/O is the Log Recorders component.
Version 2.6 (May 19 2014)
- Fix file list cap to actually do something, and not throw exceptions when hitting the cap.

- Robustness for plugins missing descriptors, such as on special slave launchers.
- JENKINS-22326 Deadlock in logging.
Version 2.0 (Mar 20 2014)
