hostgroup as a prefix (or a custom tag)

[unixengineer]

I am using OMD (Check_mk) with graphios, and able to send the metrics to carbon/graphite.

I am also trying to use grafana for graphing the metrics, and I feel it would help if the metrics have a hostgroup in the name so I can easily fetch them (say .. webservers*).

I am using this in pnp4nagios.cfg file:
service_perfdata_file_template=DATATYPE::SERVICEPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tSERVICEDESC::$SERVICEDESC$\tSERVICEPERFDATA::$SERVICEPERFDATA$\tSERVICECHECKCOMMAND::$SERVICECHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$\tSERVICESTATE::$SERVICESTATE$\tSERVICESTATETYPE::$SERVICESTATETYPE$\tGRAPHITEPREFIX::$_SERVICEGRAPHITEPREFIX$\tGRAPHITEPOSTFIX::$_SERVICEGRAPHITEPOSTFIX$

graphite tree looks like: mycompany-->myorg-->omd-->10_8_18_2->CPULoad->Load1
