Using Mimosa hardware of various flavors but all with current software. LibreNMS will stop collecting snmp data from them even though they are up, empty graphs. It doesn’t show them down nor is there an issue with other hardware either side of the Mimosa. I can snmpwalk and get info from them when this happens, just no data graphed. It may graph fine for a couple of days or a week. I do get a bit of a pause when walking them. Usually if I shut snmp off on the device, wait for LibreNMS to show it down, then re-enable snmp on the device it will work again for a period of time.
Any ideas how to correct this?
@robdb weren’t having issues with Mimosa yesterday?
Per Mimosa, there is a bug with current firmware that causes SNMP to occasionally crash. My workaround is to monitor with SNMP when possible but alert on ICMP.

@tlkhorses so for now until Mimosa fixes there a bug in SNMP. You can setup your device down alert rule to only alert on icmp. like this.
ok, thanks. It was driving me nuts.
