Configure Analytics Alarms

Device Alarm Types

The following table lists the device alarm types for Versa Analytics nodes, and the default destination and severity for each type.

Configure Device Alarms

Each Analytics node generates alarms when resources, such as CPU usage, exceed their usage thresholds. Analytics device alarms are enabled for all resources by default. You can modify the resource thresholds that trigger the alarms, and you can disable alarms for individual resources.

To modify Analytics device alarm thresholds and disable or enable device alarms:

1. In Director view, select the Analytics tab in the top menu bar.
2. Select Administration  > Configurations > Log Collector Exporter in the left menu bar.
3. In the Driver Hosts field, select the Analytics node.
4. Select System > Alarm Settings.
   
   
    
5. Click +Add Alarms Settings. The Add Alarm Settings popup window displays.
   
   
    
6. Enter information for the following fields.
    

   Field	Description
   Alarm Type	Select an alarm type: CPU Utilization—Versa Analytics system CPU utilization threshold alarm. Disk Utilization—Versa Analytics system disk utilization threshold alarm. Versa Analytics Driver Stuck—Alarm generated when the Versa Analytics driver is stuck in a non-functional state.  Memory Utilization—Versa Analytics system memory utilization threshold alarm. Remote Collector Down—Remote collector down alarm.  Remote Collector Queue Utilization—Remote collector queue utilization threshold alarm.
   Soak Time	Waiting period before alarm is reported, in seconds.
   Severity	(For alarm types Versa Analytics Driver Stuck and Remote Collector Down only.) Select the severity for the alarm.
   Low Threshold	(For all alarm types except Versa Analytics Driver Stuck and Remote Collector Down.) Enter the low threshold for the resource listed in the alarm type field. When the resource exceeds this threshold, the Analytics node generates an alarm. You select the severity assigned to this alarm in the Override Low-Threshold Alarm Severity field, below.
   High Threshold	(For all alarm types except Versa Analytics Driver Stuck and Remote Collector Down.) Enter the high threshold for the resource listed in the alarm type field. When the resource exceeds this threshold, the Analytics node generates an alarm. You select the severity assigned to this alarm in the Override High-Threshold Alarm Severity field, below. When resource usage returns to a level below this threshold, the node generates a severity Cleared alarm.
   Override Low-Threshold Alarm Severity	(For all alarm types except Versa Analytics Driver Stuck and Remote Collector Down.) Select the alarm severity level for low-threshold alarms.
   Override High-Threshold Alarm Severity	(For all alarm types except Versa Analytics Driver Stuck and Remote Collector Down.) Select the alarm severity level for high-threshold alarms.
   Disable	Disable the alarm.

7. Click Save.

View Device Alarms

You can view Analytics device alarms from the Monitor tab in the Director GUI. To do this, you must configure Analytics nodes to stream device alarm logs to Director nodes. For information, see Export Alarm Logs to Director Nodes in Configure Log Collectors and Log Exporter Rules.

To view Analytics device alarms in Director view, select the Monitor tab. Then, in the Organization drop-down list, select Director. The Analytics section in the Recent Events pane displays a count of Analytics device alarms by severity level.

In the Analytics section, select View Details to view a table of device alarms.

Stream Device Alarms to Third-Party Remote Collectors

You can stream Analytics device alarms to third-part remote collectors. In typical configurations, you create an exporter rule to export alarm logs of all types, including alarms from branch and controller devices, to third-party remote collectors. In this case, Analytics device alarms are included, and no further configuration is required.

To create a separate exporter rule to stream only Analytics device alarms to a third-party collector:

• To export all Analytics device logs, select log type va-alarm-type.
• To export individual alarm subtypes, select the subtypes from the list under va-alarm-type. 

For more information about exporting logs from Analytics nodes, see Configure Log Collectors and Log Exporter Rules.

Configure Cluster Alarms

To modify cluster resource thresholds and to enable email notifications for alarms:

1. In Director view, select the Analytics tab.
2. Select Administration > Configuration > Settings.
3. In the main pane, select the System Monitoring tab. Enter information for the following fields.
   
   
    

   Field	Description
   Enable Monitoring on this Machine	Toggle On to enable monitoring of the listed thresholds. Toggle Off to disable.
   Email Notifications	Toggle On to send email notifications when thresholds are exceeded. Toggle Off to disable.
   Search Disk Usage Threshold	Enter a threshold value for disk usage on search-type Analytics nodes as a percentage of disk.
   Search Memory Usage Threshold	Enter a threshold value for memory usage on search-type Analytics nodes as a percentage of memory.
   Analytics Disk Usage Threshold	Enter a threshold value for disk usage on analytics-type Analytics nodes as a percentage of disk.
   Analytics Memory Usage Threshold	Enter a threshold value for memory usage on analytics-type Analytics nodes as a percentage of memory.
   Search Logs Threshold	Enter a threshold value for the number of search logs, in kilobytes.

4. Click Save.
5. (Optional) If you enabled Email Notifications in Step 3, perform the following steps to configure email settings.
   1. Select Administration > Configuration > Settings in the left menu bar. The Settings screen displays.
      
      
       
   2. Select the Email Configuration tab, and then enter information for the following fields.
       

      Field	Description
      SMTP Host	Enter the name of the Simple Mail Transfer Protocol (SMTP) host.
      SMTP Port	Enter the port number to use to connect to the SMTP host.
      Username	Enter the username to use to connect to the SMTP server.
      Password	Enter the password to use to connect to the SMTP server.
      SSL	Click to use SSL encryption.
      TLS	Click to use TLS encryption.
      Sender Email	Enter the email address to place in the From: field of the email.
      System Email Notifications	Enter the email address to which to send Analytics monitoring notifications. To enter more than one email address, separate them with commas.

   3. Click Save Configuration.
