F5 to be monitored using the Solarwinds

yes, its possible. you have to configure snmp

What will be the oid to be used?

the interfaces can be collected with default interface mib, like with any other snmp device. Its like a linux system.

If you need more detailed information look here: https://devcentral.f5.com/articles/cacti-creating-templates-for-indexed-snmp-data.UtaF-Pv9b0M

you need the f5 mib, which you can download from your f5 device

SolarWinds NPM will monitor an F5 serving out SNMP responses without the need for any MIB installation or custom configuration. NPM 10.6.1 (and probably earlier but recent-ish versions) has native F5 discovery and will display (but not track/chart) pools and virtual servers with simple UP/DOWN reporting. All your interfaces, trunks, vlans along with CPU and memory utilization, connection count, throughput, etc. will be tracked and charted over time. This all used to be painful with NPM but now is all trivially automagic. If there are extra OIDs you want to track such as the number of HTTP requests per hour (sysHttpStatNumberReqs) you can easily add a custom poller to fetch specific data.

We use NPM 10.7 and still we have issues with CPU false reading since it allways reports 100 % of CPU Utilization on C36 LTM.

have you tried this?
