Tip of the month January - Monitor SMSEagle with SNAG-View 4 and vice versa
by Michael Rütten
In addition to the usual metrics such as CPU, RAM, disk space and network load, the following metrics relevant for sending SMS and operating the modem can also be called up via the SNMP service of the SMSEagle add-on.
- Signal strength (per antenna)
- SMS sent (in the last 24 hours and the last 30 days)
- Failed transmissions (in the last 24 hours)
- Humidity (on the module)
- Temperature (on the model and on the antenna)
- Number of SMS in the inbox folder
- Number of SMS in the outbox folder
To retrieve these metrics, the SNMP service must be activated on the SMSEagle!
Monitoring via Telegraf SNMP plug-in

A device with the IP address of the SMSEagle add-on is then created with a sensor that uses the previously created command.
The following graphic shows the corresponding output.
Monitoring via Nagios SNMP plugin
Alternatively, these metrics can also be retrieved via Nagios plugins. These are provided by SECTOR NORD on request.
Monitoring SNAG-View 4 with SMSEagle
Every current SMSEagle device can and should be used to monitor the SNAG-View server!
If the SNAG-View server fails and/or is no longer accessible, the SMSEagle immediately informs you of this fault via SMS, VoiceCall or Signal. A regular ping or port check can be set up under “Network Monitoring” for this purpose.
