Manage alarm thresholds
An alarm threshold defines the minimum value of the specified indicator that triggers an alarm. You can set CPU usage, memory usage, disk usage, disk I/O throughput, and network throughput alarm thresholds.
Alarm threshold management enables you to view the predefined alarm thresholds and configure the alarm server and alarm thresholds.
Restrictions and guidelines
By default, the host that runs the UIS Manager operates as an alarm server. In a stateful failover system, the primary management node operates as an alarm server.
To enable an alarm threshold, you must complete the configurations of the alarm threshold.
Configure alarm servers
On the top navigation bar, click Cloud Resources, and then select Monitoring and Alarms > Alarms > Alarm Thresholds from the navigation pane.
Click Configure Alarm Servers.
Enter the IP address of an alarm server, and then click the Add icon
.
The IP address will be added to the box below.
To remove alarm servers, select the servers, and then click the Delete icon
.
Click OK.
Edit an alarm threshold
On the top navigation bar, click Cloud Resources, and then select Monitoring and Alarms > Alarms > Alarm Thresholds from the navigation pane.
Click the Edit icon
for an alarm threshold.
Configure the parameters as described in "Parameters."
Click OK.
Enable or disable an alarm threshold
On the top navigation bar, click Cloud Resources, and then select Monitoring and Alarms > Alarms > Alarm Thresholds from the navigation pane.
Click the On icon
or Off icon 
for an alarm threshold.
In the dialog box that opens, click OK.
Bulk enable or disable alarm thresholds
On the top navigation bar, click Cloud Resources, and then select Monitoring and Alarms > Alarms > Alarm Thresholds from the navigation pane.
Select one or more alarm thresholds, click Batch Actions, and then select Batch Enable or Batch Disable.
In the dialog box that opens, click OK.
Parameters
Critical: Minimum value of the metric that triggers a critical alarm.
Major: Minimum value of the metric that triggers a major alarm.
Minor: Minimum value of the metric that triggers a minor alarm.
Info: Minimum value of the metric that triggers an informational alarm.
Duration: If the metric value stays above the threshold for a time period specified by this parameter, the system generates an alarm. This parameter is required for host resource, VM resource, and cluster resource alarms.
Alarm Interval: Report interval for a type of alarms for an alarm source. The default is 0 days. This parameter is required for host resource, VM resource, cluster resource, and failure alarms.
