Probe for Signal Strength on MikroTik devices

RouterOS The Dude
1

Hello together,

I try to check the Signal-Strength with a probe but I’m faling at it. It would be great if someone could help me building a probe for it.

Because there was alredy the function “snmp_wireless_link_info()” I’ve tryed to use parts of it in an function probe and check it aginst a fixed value in an if question. But the returns seems to be empty all the time. The OIDs changes from device to device - so use one single OID would be a Pain to configure for every single device.

edit:
Exists a Wildcard, or is it possible to collect all informations deeper then
iso.org.dod.internet.private.enterprises.mikrotik.mikrotikExperimentalModule.mtXRouterOs.mtxrWireless.mtxrWlStatTable.mtxrWlStatEntry.mtxrWlStatStrength.
in an array?

Because there was alredy the function “snmp_wireless_link_info()”

Make sure you have tried to monitor the option on station router.

Exactly this is what i mean - This OIDs changes on every device :frowning:

Please, specify what do you want to monitor.

  • signal strength on the station router. Is it right?

I like to make a Probe to check the Signal-Strength is under -75dBm, suitable for all Mikrotik-Based devices. Just for Station devices would be sufficient. But on every Station the OID for the Signal-Strength is different, so i can’t make just one probe - I won’t make for every device it’s own probe.
