# `check_lvm_thinpools`
|
|
|
|
This is a re-implementation of the Perl [`check_lvm_thinpools`](https://github.com/neingeist/check_lvm_thinpools/). That is used to check the free capacity in Linux Logical Volume Manager (LVM) [thin pools](https://www.linux.org/docs/man7/lvmthin.html).
|
|
|
|
The check uses the [nagiosplugin](https://pypi.org/project/nagiosplugin/) framework to output metrics. Multiple thin pools are supported too.
|
|
|
|
```
|
|
$ ./check_lvm_thinpools
|
|
LVMTHINPOOLS OK - data percent (workhero_nvme/nvmepool) is 61.78% | 'data_workhero_nvme/nvmepool'=61.78%;70;90;0;100 'meta_workhero_nvme/nvmepool'=34.21%;70;90;0;100 data_percent=61.78%;70;90;0;100 metadata_percent=34.21%;70;90;0;100
|
|
```
|
|
|
|
Supported command line arguments can be listed with the `--help` command line argument.
|
|
|
|
```
|
|
$ ./check_lvm_thinpools --help

|
