Kubernetes Volumes discovery fails

Steps to reproduce:

1. Add PVC volume to kubernetes host, or any long fs name
2. Add host via zabbix agent2 to zabbix, and add default Linux template
3. Open Configuration > Hosts > select host
4. Select Discovery Rules in top menu
5. Click red  symbol next to „Template Module Linux filesystems by Zabbix agent: Mounted filesystem discovery”

Result:

PVCs are not discovered, as trigger creation fails.

„Cannot create trigger: value "/var/lib/kubelet/plugins/kubernetes.io/csi/pv/pvc-cb944255-a513-4efc-b2b1-342c3cb36347/globalmount: Disk space is critically low (used > {$VFS.FS.PUSED.MAX.CRIT:"/var/lib/kubelet/plugins/kubernetes.io/csi/pv/pvc-cb944255-a513-4efc-b2b1-342c3cb36347/globalmount"}%)" is too long.”
(See screenshot)

Expected:
Also long fs names are possible for triggers.
