I got this to work, here are the details as to how I did it...
Fiirst, you need to download AdventNet Linux Agent from
http://www.linuxmonitor.comThen...
On OpManager: 1) Imported AdventNet Linux Agent.MIB from LinuxAgent\mibs to opManager MIB Browser
2) Create Device Template for LinuxAgent
OID .1.3.6.1.4.1
Vendor AdventNet
3) Create an SNMP v1/v2 Credential Setting named "LinuxAgent" using port 8001. Read should
be "public" and write should be "private"
On Linux Box: 1) Setup LinuxAgent at /usr/local/ManageEngine/LinuxAgent
2) chmod +x linuxagent
3) Execute sh /usr/local/ManageEngine/LinuxAgent/install-startup.sh (to make it run on startup)
4) Execute sh /usr/lcoal/ManageEngine/LinuxAgent/StartAgent.sh (to start now)
5) Open udp port 8001 on firewall
On OpManager: 1) Add the device using LinuxAgent for SNMP Credential
