i edited cfg file (/opt/omd/sites/sitename/etc/pnp4nagios/pages) to include CPU, filesystem and memory)

Is it possible to get report only for root volume (Filesystem / ) not for Filesystem /var, Filesystem /opt/omd etc....

i tried with regular expression

^Filesystem[ ]\/
^Filesystem[]\/$
[Filesystem \/]

But all fail

define page { use_regex 1 page_name My Performance Report }

define graph { host_name host1 | host2 | service_desc CPU|Memory|Filesystem
source 1 image } `
