I am trying to monitor Juniper EX3200 and probings are strange.

Memory is always 99% and interface traffic is not correct.

I believe I do not monitor it correctly.

Here is what I have in device template. 

System OID=.1.3.6.1.4.1.juniperMIB.jnxProducts.1.1.2.30

CPU  .1.3.6.1.4.1.2636.3.1.13.1.8

Memory Utilization   .1.3.6.1.4.1.2636.3.1.13.1.12

I cannot find OID for them. These are automatically populated after I add  1.3.6.1.4.1.2636

Here is what I had done.

I downloaded https://www.juniper.net/techpubs/en_US/release-independent/junos/mibs/mibs.html.

I then upload everything in /JuniperMibs and /StandardMibs to /opt/ManageEngine/OpManagerProbe/mibs

Did I do anything wrong?

I want to monitor interface traffic, CPU, Memory and other basic stuff.

Please help.

Thanks

Andy
