// "active", and "sub" are valid systemd state types.
|
||||
// Originally, this application used a shared RRD file
|
||||
// for each systemd state type. However, LibreNMS does
|
||||
// not support adding new metrics to existing RRDs.
|
||||
// Therefore, existing metrics are now associated with
|
||||
// the "shared" string and any NEW metrics/state statuses
|
||||
// added to the associative array below MUST specify the
|
||||
// "individual" moniker. This will create a NEW RRD file
|
||||
// for the new metric. For example, the "start" sub
|
||||
// service state status was added originally and the
|
||||
// metric is stored in the following RRD:
|
||||
// app-systemd-132-sub_service.rrd
|
||||
// However the "dead-before-auto-restart" sub service
|
||||
// state status was added after the fact and a new RRD
|
||||
// file name is stored with the new format:
|
||||
// app-systemd-132-sub_service-dead-before-auto-restart.rrd
