Steps to reproduce:

1. Add the template "Template OS Linux by Prom" to a Linux host
2. Check the items for the application "filesystem /"

Result:

4 of the 5 items have a status of "not supported"

The error message for the items "Total space" and "Free space" :

Preprocessing failed for: # HELP go_gc_duration_seconds A summary of the GC invocation durations..# TYPE go_gc_duration_sec...
1. Failed: cannot apply Prometheus pattern: data extraction error: multiple matching metrics found:

node_filesystem_size_bytes

{device="*/dev/mapper/centos_ronflex-root*",fstype="*xfs*",mountpoint="/"}

1.072693248e+10
node_filesystem_size_bytes

{device="*rootfs*",fstype="*rootfs*",mountpoint="/"}

1.072693248e+10

Expected:

The rootfs filesystem should be filtered
