check_welle-cli

This is a Python script. Python3 is needed.

These are the commandline parameters:

-h	Shows this help
Mandatory
--sid	Service ID (SID). E.g. 0x8064
--url	The url to open. E.g. http://ip_of_welle_cli/
--file	For testing purposes, to open a json file. E.g. file:///c:/path/to/
	(--url or --file is mandatory)
Optional
--audio_low_warn	Audio warning level threshold in dBFS. If audio is BELOW this threshold then a warning state is returned. E.g. -40.0
--audio_low_crit	Same, but for critical level
--audio_high_warn	Audio warning level threshold in dBFS. If audio is ABOVE this threshold then a warning state is returned. E.g. -3.5
--audio_high_crit	Same, but for critical level
--time_secs_warn	Define the max age threshold in seconds of the last audio update before a warning state is returned. E.g. 60
--time_secs_crit	Same, but for critical level
--bitrate_warn	Define the bitrate warning threshold in kbps. E.g. 71 (a 72 kbps stream will return OK then)
--bitrate_crit	Same, but for critical level
--dls_secs_warn	Define the max age threshold in seconds of the last Dynamic Label Segment (DLS) update before a warning state is returned. E.g. 3600
--dls_secs_crit	Same, but for critical level
--snr_warn	Define the Signal to Noise Ratio (SNR) when a warning state is returned. E.g. 6.0
--snr_crit	Same, but for critical level
--channel	Set welle-cli to this channel. E.g. 7B. If this parameter is not set, the current welle-cli channel is used to find the SID. If welle-cli needs to switch channels then this function might take several seconds waiting for welle-cli to demux the mux on that channel
--channelupdate	Test mode. If set, the channel will always be updated to welle-cli, regardless if a real change of the channel is needed
--verbose	Test mode. Verbose output

Example command definition:
# This command will check:
# 1. If the audio level is above -40 dBFS and below -3.3 dBFS.
# 2. If the audio level is updated less than 60 seconds ago.
# 3. If the bitrate is above 71 kbps.
# 4. If the dls is updated less then 1 hour ago.
define command{
command_name check_welle-cli
command_line $USER1$/check_welle-cli.py --url $ARG1$ --sid=$ARG2$ --audio_low_crit=-40 --audio_high_crit=-3.3 --time_secs_crit=60 --bitrate_crit=71 --dls_secs_crit=3600
}


Example service definition:
# This service will do the check for DAB+ service id 0x8064 on the DAB+ allotment where welle-cli is currently tuned into.
define service{
use generic-service
host_name dabreceiver
service_description Check RSM DAB+
check_command check_welle-cli!http://192.168.1.45/!0x8064
}


Example output:
OK - DAB+ Service 0x8064 (RSM) has audiolevel -5.3 dBFS at bitrate 72 kbps. Audiolevel updated 2 seconds ago at: 2021-01-05 17:08:57. DLS updated 11 seconds ago at: 2021-01-05 17:08:48. SNR: 7.0. Channel: 7B.
