The script `/usr/bin/check_cvmfs_repos` installed by the CVMFS monitoring role `hxr.monitor-cvmfs` takes longer than 2 minutes to run (the Telegraf timeout for this script) due to misbehaving CVMFS servers and serial execution. This results in no measurements being registered. ``` Jul 25 13:52:00 cvmfs1-ufr0.internal.galaxyproject.eu telegraf[2616631]: 2024-07-25T11:52:00Z E! [inputs.exec] Error in plugin: exec: command timed out for command "/usr/bin/check_cvmfs_repos": /usr/bin/check_cvmfs_repos: line 9: [: : integer expression expected... ``` Add timeout to `curl` calls in `check_cvmfs_repos` script from CVMFS monitoring role `hxr.monitor-cvmfs` and parallelize all `check_repo` calls so that the script is guaranteed to exit before it times out.

The outcome is a fixed dashboard. |
