Make exclude filters in graphite path work

[Tqnsls]

It seems it is currently not possible to exclude specific paths however it is possible to include only some specific path .

Status Quo

In the example I have these graphite paths for the disk command check for my /home mountpoint.

icinga2.myhostname.services.myservicename.disk.perfdata._home.value
icinga2.myhostname.services.myservicename.disk.perfdata._home_inode_free.value
icinga2.myhostname.services.myservicename.disk.perfdata._home_inode_percent.value
icinga2.myhostname.services.myservicename.disk.perfdata._home_inode_used.value

The problem is there are different mountpoints that I can not create each a template for all the mountpoints..

What I want to include only

icinga2.myhostname.services.myservicename.disk.perfdata._home.value

So I want to exclude

icinga2.myhostname.services.myservicename.disk.perfdata._home_inode_free.value
icinga2.myhostname.services.myservicename.disk.perfdata._home_inode_percent.value
icinga2.myhostname.services.myservicename.disk.perfdata._home_inode_used.value

My Goal is ..

to let the graphs look somewhat like this

However, it just looks like this (look specifically at the last four graphs):

I also checked the icinga-web-graphite-integration docs and tried with the braces but could not get it to work.

In grafana for example it can be done by using the function exclude:

The metrics_filters I tested with

This filter obviously only includes the "icinga2.myhostname.services.myservicename.disk.perfdata._home_inode_used.value"

[disk_with_inodes_inode_usage.metrics_filters]
inode_used_value = "$service_name_template$.perfdata.$disk$_inode_used.value"

And this should exclude all inode paths and therefore only include "icinga2.myhostname.services.myservicename.disk.perfdata._home_inode_free.value"

[disk_with_inodes.metrics_filters]
value = "$service_name_template$.perfdata.$disk:{?!*inode.*}$.value"
