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 .
