Collector slabinfo (#6800)
### Summary
Provide new collector parsing `/proc/slabinfo` to provide details on kernel slab structures.
Asked by issue #13 (very happy for the oldest issue in backlog)
##### Component Name
collectors/slabinfo.plugin
##### Additional Information
This slabinfo details allows to have clues on actions done on your system.
In the following screenshot, you can clearly see a `find` done on a ext4 filesystem (the number of `ext4_inode_cache` & `dentry` are rising fast), and a few seconds later, an admin issued a `echo 3 > /proc/sys/vm/drop_cached` as their count dropped.

They are modular since they accept custom made modules to be included. Writing modules for these plugins is easier than accessing the native Netdata API directly. You will find modules already available for each orchestrator under the directory of the particular modular plugin (e.g. under python.d.plugin for the python orchestrator). Each of these modular plugins has each own methods for defining modules. Please check the examples and their documentation. |
