Monitoring Resources Using CLI
OpManager monitors the system resources using SNMP by default.
However, in the absence of SNMP on the devices, the non-SNMP Linux
devices can be monitored using CLI, ie., Telnet or SSH.. All the Unix
Servers templates have the
resource monitors preconfigured. All you will need to do is disable the
SNMP monitors associated and select the CLI monitors and associate them
to the required devices.
For monitoring the unix servers, make sure either Telnet or SSH is
enabled on them.
Steps to configure Telnet/SSH Monitoring
Go to the device snapshot page.
- From Monitors --> Performance Monitors section, remove the
SNMP-based monitors if any.
- Click Add Monitors link on the right bottom.
- Now, from the list of resource monitors, select the CPU, Memory,
and Disk Utilization monitors which has the protocol name as CLI
against the monitor name.
- Click OK. The monitors are added in the template under the
- Click Apply. All the servers to which the monitors are associated
are listed. Another column also displays devices which are classified
as 'Unknown'. You can pull the required devices from this list too.
Click Apply once again.
The CLI-based monitors are associated to the device.
