# check_mk_kernel_version
check_mk plugin to monitor if running kernel mach (last) installed version
Testet with:
- FreeBSD
- Debian
- Proxmox (thanks @mdklapwijk)
check cmds for others are welcome
## cli cmds to get installed and running kernel versions
### FreeBSD:
#### running kernel
sysctl -n kern.osrelease
10.3-RELEASE-p11
#### installed kernel
freebsd-version -k
10.3-RELEASE-p11
### debian/ubuntu
#### running:
sysctl -n kernel.version | awk '{print $4}'
3.16.39-1+deb8u2
#### installed
# different kernel versions may be installed, so we need to compare
# all available versions to find the latest
# get the version of the currently running image as start
latest=$(dpkg -l | grep linux-image-$(uname -r) | awk '{print $3}')
for i in $(dpkg -l | grep linux-image-$(uname -r | cut -d '.' -f1) | awk '{print $3}')
do
dpkg --compare-versions $i gt $latest && latest=$i
done
echo $latest
3.16.39-1+deb8u2
## Install
### OMD Server Install
#### check_mk package:
```
mkp install releases/kernel_version_compare-.mkp
```
#### manually:
```
cp checks/kernel_version_compare /omd/sites/$(OMD_SITE)/local/share/check_mk/checks/
cp plugins/kernel_version_compare /omd/sites/$(OMD_SITE)/local/share/check_mk/agents/plugins/
cp packages/kernel_version_compare /omd/sites/$(OMD_SITE)/var/check_mk/packages/
```
#### use make target:
```
usage: make [target ...]
pkg:
pkg......................alias for package
package..................build check_mk package from installed repo files
release..................build check_mk package and copy *.mkp file to repo
dev:
install..................install check_mk plugin, optional OMD_SITE=cfa can be overwritten
purge....................purge check_mk plugin files, optional OMD_SITE=cfa can be overwritten
system:
help.....................show this help
```
### Client Install
```
cp plugins/kernel_version_compare /usr/lib/check_mk_agent/plugins/kernel_version_compare
```
Or download plugin from OMD Server, or rollout plugin with puppet ;-)
## DEV hints
```
# test if check is found on server
check_mk -L | grep kernel_version_compare
kernel_version_compare tcp (no man page present)
# test check on server
check_mk -v --checks=kernel_version_compare host01.example.com
Calling external program ssh -o ConnectTimeout=10 -l monitor 192.168.1.1
Kernel-Version FreeBSD OK - Kernel version running 10.3-RELEASE-p20 match installed version
