I am working on a project with requirements of creating PRTG sensors to monitor router interfaces status including in/out throughput, error rate and interface status (up/down).
I can do snmpwalk to scan the interfaces and it returns results.
But I am struggling creating PRTG sensors and have tried SNMP Traffic/JFlow v5/JFlow v5 (custom)/SNMP Library(download the Juniper MIB online for Interfaces)/SNMP custom/SNMP custom table.
None of above worked for me.
BTW, we also have Solarwinds and Splunk, no issues with this at all.
