I'm not able to view the CPU Data while monitoring Linux systems in SNMP mode.

I'm not able to view the CPU Data while monitoring Linux systems in SNMP mode.

Applications manager queries the OID in HOST-RESOURCES.mib for getting the CPU data in SNMP mode. In linux machines the OID does not return any value. Hence the UCD-MIB is queried. For this purpose you need to enable the permission for viewing the UCD MIB OIDs.

To grant permission,
  1. Edit snmpd.conf file usually located in /etc/snmp/ directory.
  2. Add the following view under views.

#

name

incl/excl

subtree

mask(optional)

view

systemview

included

.1.3.6

 

  1. Grant access to that view by adding the following.

#

group

context

sec.model

sec.level

prefix

read

write

notif

access

notConfigGroup

""

any

noauth

exact

systemview

none

none

  1. Start the SNMP agent.
