graphite default template is not catching all values

[eichlerla2]

Expected Behavior

Graphite converts dots (".") in the perf values of a check to an slash.

Perfdata

/usr/lib/nagios/plugins/check_disk -w 15% -c 10% -l -X tmpfs -X devtmpfs -X proc -X sysfs -X udev -X devpts
DISK OK - free space: / 5255 MB (54% inode=90%); /boot 411 MB (90% inode=99%); /opt/mysql.abc 40102 MB (41% inode=99%); /opt/mysql.def 28598 MB (18% inode=99%);| /=4312MB;8567;9071;0;10079 /boot=42MB;406;430;0;478 /opt/mysql.abc=55571MB;85674;90713;0;100793 /opt/mysql.def=122657MB;135444;143412;0;159347

is stored by graphite as

disk_dynamic # tree 
    └── perfdata
        ├── _
        │   ├── crit.wsp
        │   ├── max.wsp
        │   ├── value.wsp
        │   └── warn.wsp
        ├── _boot
        │   ├── crit.wsp
        │   ├── max.wsp
        │   ├── value.wsp
        │   └── warn.wsp
        ├── _dev
        │   └── value.wsp
        └── _opt_mysql
            ├── abc
            │   ├── crit.wsp
            │   ├── max.wsp
            │   ├── value.wsp
            │   └── warn.wsp
            └── def
                ├── crit.wsp
                ├── max.wsp
                ├── value.wsp
                └── warn.wsp

So some perf values are stored in subfolders below the normal folder. The default template should also catch the values in subfolders.

Current Behavior

Graphs from values in subfolders are not shown in icingaweb2.

Possible Solution

Graphs in subfolders should also shown. Maybe if metrics_filters value $perfdata$ is able to catch everything between perfdata and value.

[default-service.metrics_filters]
value = "$service_name_template$.perfdata.$perfdata$.value"

Steps to Reproduce (for bugs)

1. mount a filesystem with a dot in the mountpoint name
2. configure a disk service based on check_disk in icinga2
3. run this configuration -> let collect icinga2 perfdata of this service
4. check shown graphs in icingaweb2

As discussed w/ @bobapple (offline):

This may be an Icinga 2 issue (s/./_/).
