Check starface-channel-status

Overview

Counts the number of active DAHDI, SIP, and other channels on a Starface PBX, and alerts on channel overusage when a maximum call limit is configured on the PBX.

Important Notes:

Data Collection:

  • Connects via socket to the Starface Monitoring Module on port 6556

  • Supports both IPv4 (default) and IPv6

  • Fetched data is cached for up to one minute in a shared SQLite database, so that multiple Starface checks running in parallel do not overload the PBX

Counts the number of active DAHDI, SIP, and other channels on a Starface PBX
via its monitoring module on port 6556. Alerts when channel usage exceeds the
configured percentage threshold. Supports both IPv4 and IPv6. Data is cached
to avoid overloading the PBX when multiple checks run in parallel.

options:
  -h, --help            show this help message and exit
  -V, --version         show program's version number and exit
  --always-ok           Always returns OK.
  --cache-expire CACHE_EXPIRE
                        The amount of time after which the credential/data
                        cache expires, in minutes. Default: 1
  --critical CRIT       CRIT threshold in percent. Default: >= 90
  -H, --hostname HOSTNAME
                        Starface PBX hostname or IP address. Default:
                        localhost
  --port PORT           Starface PBX monitoring port. Default: 6556
  --test TEST           For unit tests. Needs "path-to-stdout-file,path-to-
                        stderr-file,expected-retc".
  --timeout TIMEOUT     Network timeout in seconds. Default: 8 (seconds)
  --warning WARN        WARN threshold in percent. Default: >= 80
  --ipv6                Use IPv6.

Usage Examples

./starface-channel-status --cache-expire 1 --hostname mypbx --port 6556 --timeout 3

Output:

Current channels: 4x DAHDI, 7x SIP

States

  • OK if channel usage is below the warning threshold (or no maximum call limit is configured).

  • WARN if channel usage is >= --warning (default: 80%).

  • CRIT if channel usage is >= --critical (default: 90%).

  • --always-ok suppresses all alerts and always returns OK.
