Retrieves the status of an SMS Modem via smstools3.
This plugin checks the status of an SMS modem using the regular_run functionality provided in smstools3.
It does not directly access the modem, but instead reads a status file generated by smstools3.
This plugin works with smstools3 and the regular_run functionality to check the status of a modem (signal strength, GSM Provider etc.). By not accessing the modem directly, we don't have any concurrent access problems. N.B. this script was developed for the MultiTech Network Modems, but should function with any standard GSM modem.
check_sms3status [options] <status_file>
In order to work the following options need to be set in smsd.conf:
regular_run_interval = 60 regular_run_cmd = AT+CREG?;+CSQ;+COPS? regular_run_statfile = <status_file>
The following performance data is returned
<signal dBm>;<% signal strength>;<Error rate>;<Network ID/Name>
<status_file> the status file e.g. /dev/shm/sms_stat
|--warning||warning level for percentage signal strength (default 40)|
|--critical||critical level for percentage signal strength (default 20)|
|--timeout||how long to wait for the file (default 30)|
|--age||the maximum age of the file in seconds (default 300)|
