Inodes Monitor

This plugin offers a NodeMonitor implementation for inodes.

It also offers to configure a threshold below which the node will automatically be put on/offline.

it only works for Unix/Linux nodes where the df command is available.


Inodes are basically a table for the files of the filesystem. On many Linux FS, it has a fixed size. It’s very important to monitor, like the disk space, because the effect is exactly the same: if you run out of inodes, then you can’t write on the disk anymore!

And if you don’t know about it, you may scratch your head quite a long time wondering why Jenkins is telling you there’s no more disk space left, when you see there’s still dozens of GB available…​

Basically, the plugin uses the df command with the POSIX portability flag:

df --portability --inodes .
