有没有办法跟踪 Jenkins 中全局共享库的使用情况？

Question

Context:

• At my work most developers are free to write their own Jenkinsfile for their own team's projects.
• As the Jenkins admin, I provide developers with a global shared library.
• Most projects are using either v1 or v2 or v3 or another version of this library, using the idiom library("theSharedLib@v#") .

Question: Is there a way for me to find out which Jenkinsfile is using which version of the shared library without having to actually lookup into all those Jenkinsfile files (50+ files in as much git repos)?

What I would see best is some mechanism that write up (into a file on the Jenkins master or in a DB) which project/Jenkinsfile is using which version at the time the library is loaded.

A possible solution would be to add some code to every function inside the library that will actually do this reporting. I could then see which function is used by who. Any better solution?

I wrote https://github.com/CiscoDevNet/es-logger to gather information such as this from Jenkins. It has a plugin that will run a regex against the console log of a completed job and can then post events to elastic search.

Jenkins helpfully posts library loads at the start of the log such as:

Loading library sharedLib@version

So a simple regex like

"^Loading library\S+(?P<library_name>.*?)@(?P<library_version>.*?)\S+$"

added to the console_log_events plugin would generate events in an elastic search for each usage and each version.
