// The 'load' and 'active' states only have
// two layers of depth in the systemd data returned
// by the snmp script.  The 'sub' state has three
// layers.  If another state type is introduced
// with three layers it must be added to the list
// here.
$state_type_ternary_depth = ['sub'];

// Any new systemd state types MUST be added to this list.
$systemd_state_types = ['load', 'active', 'sub'];

// Associative array used by the systemd application to
// build graphs, rrd names and descriptions, and parse
// the systemd.py script results.  Currently "load",
// "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
//
