Configuring thresholds for monitors
Configuring thresholds enable OpManager to proactively monitor the
resources and the
services running on them and raise alerts before they go down or reach
the critical condition. You can configure thresholds for the monitors
that are associated to a single device, configure from the device
template in order to apply across multiple devices and also configure
from Quick Configuration Wizard.
Configure threshold limits for the monitors associated to a single
device
- Go to the device snapshot page.
- Under Monitors tab, click on the edit icon
corresponding to the
monitor for which you want to configure threshold limits. Edit Monitor
page opens.

- Ensure that the SNMP OID and
the monitoring Interval are
configured.
- Select the Threshold Alert
condition [>,= or <] and enter the value. Alert is raised if the
monitored value is greater than, equal to or lesser than (which ever is
selected ) the threshold value.
- Enter the Rearm Value.
Rearm value is the value which the determines the monitor has restored
to normal condition. For instance, the threshold condition for a memory
monitor is selected as greater than [>] and the threshold value is
configured as 75. The monitored memory value of that device is 80. Now
alert is raised and the monitor is in violated condition. At the next
poll the monitored value is 72. An alert for returning to normal
condition is generated. At the next poll again the monitored value goes
to 80. Again a threshold violation alert is generated. In order to
avoid
this, enter the rearm value. Only if the monitored value reaches the
rearm value the monitor goes to the normal condition and a normal alert
is raised. Note: If you select threshold condition greater, then the
rearm value should be lesser than the threshold value and vice versa.
- In the Consecutive Times
field enter the value of how many consecutive times the threshold can
be violated to generate the alert.
- Click on Advanced button
to configure the Alarm Message and Severity. Based on the monitor, the
values for Alarm message and severity are pre-configured by default.
- Click on OK.
Configure threshold limits for the
devices from their device template page
- Go to the Device template page.
- Under
Monitors tab, all the
monitors that are currently associated with the devices are listed. If
you want add
or remove required monitors. Click on Edit Threshold button. Edit Thresholds
page opens.

- Configure the Threshold Alert and Rearm Value and click on OK.
- Click on Apply.
- Select the devices for which you want to associate the monitors
from the left column and move to the right column.
- Again click on Apply.
Configure thresholds for multiple
devices from Quick Configuration Wizard
- From Admin page, click
on Quick Configuration Wizard.
- Select Add Performance monitors
to several devices (SNMP, WMI and CLI) option and click on Next.
- Open the required device template page and follow the steps from 2 to 6 of Configure
thresholds for the devices from their device template page.
