Hello everybody,

In my current Jenkins I have a multi-branch jenkins pipeline setup. That is also webhooked to my bitbucket repo.

Every time a developer pushes code, it triggers a scan on all branches. There are currently about 53 branches. Sometimes a scan takes a few minutes to complete and sometimes it can take up to 20 - 30 minutes. I can also reproduce it by manually clicking the “scan multibranch pipeline”.

How can there such a big difference in the amount of minutes of the scan and how can I improve or troubleshoot this issue?

I can provide some more screenshots of my setup if needed.

Hope you can help.

Best,

Jordy

Can you post a finer log during a scan?

What is and who do you mean with function log?

Can you extract system log part, increase the log level to finer?

When the branch is already discovered, the new push should not scan anything. What bit bucket integration are you using?

It is a bit of a struggle for me atm to find/extract system log. The system logs are very large and do not let me to navigate through time stamps on the UI. I tried to retrieve it on the server, but it seems like it is either not configured or installed. I will have to wait until january 6th for the creator to guide me through the jenkins setup.

I am using bitbucket cloud integration and bitbucket branch source plugin.

Is there something else I can check in the meantime?

Well, do you have a periodic branches scan activate? Can you send me a log of manual scan?

We can close this topic. I turned on caching in section “Bitbucket Endpoints” in jenkins’ system settings.  
Now scanning takes max 1 minute.

Thank you so far
