For Fortigate 61F tried to inject MIB file using device selfcert portlet in Operator console.
After adding the mib file, there is no cpu utilization listed
Fortigate device had two mib type files.
Fortinet core MIB file and fortigate mib file.
After selecting fnmibconfomance and click GET it shows oid is not supported
Mib file uploaded previously is fortinet core MIB that shows OID is not supported and then uploaded again other mib file fortigate mib file which shows below error
Which mib should be uploaded into device selfcert portlet for this to work
Release :DX IM 20.3/20.4
Device : Fortigate 61F
In this use case fortinet core MIB file and fortigate mib file were uploaded together in the self cert portlet which resolved the issue
Note :The MIB/MIBs and any/all dependent MIBs listed in the IMPORTS section of the MIB(s) need to be loaded
Most errors tend to be caused by dependent MIBs not being loaded.
