Threshold and Availability for VMware Resource Pool Monitor

Threshold Profiles help alarms engine to decide if a specific resource is Critical, or in Trouble. After adding a VMware Resource pool for monitoring, you can configure thresholds for critical performance metrics and receive alerts, using which you can avoid many issues. 

A default threshold and availability profile for VMware Resource Pool Monitor will be automatically listed in the Threshold and Availability screen when you use for the first time. You can add new ones using the steps below: 

Adding a Threshold and Availability Profile for a VMware resource pool monitor

Log in to your Site24x7 account and follow these steps:

1. Click Admin > Configuration Profiles > Threshold and Availability.
2. Click Add Threshold and Availability on the Add Threshold Profile screen.
3. Specify the following details for adding thresholds and availability for a VMware resource pool monitor:
   • Monitor type: Select VMware resource pool from the drop-down list.
   • Display name: Provide a label for identification purposes.
4. Set the threshold conditions (<, <=, =, >, or >=) for the following performance metrics to receive alerts if they're breached. The monitor’s status changes to ”Trouble or Critical” when the condition applied to any of the below threshold strategies hold true. For VMware Datastore monitors you can configure thresholds for:
   • General Thresholds: CPU Utlization, Memory Utilization, Total number of Child Resource Pools, Total number of VMs, Number of Powered On VMs and Number of Powered Off VMs.
   • CPU Thresholds: CPU Overall Usage, CPU Maximum Usage, CPU Reservation Usage, CPU Reservation Used for VM, CPU Unreserved for Pool, and CPU Unreserved for VM.
   • Memory Thresholds: Memory Overall Usage, Memory Maximum Usage, Memory Reservation Usage, Memory Reservation Used for VM, Memory Unreserved for Pool, and Memory Unreserved for VM.
5. Advanced Threshold Settings (Strategy):
   Poll count serves as the default strategy to validate the threshold breach. You can validate threshold breach by applying multiple conditions (>, <, =, >=, <=) on your specified threshold strategy. The monitor’s status changes to ”Trouble or Critical”  when the condition applied to any of the below threshold strategies hold true:
   • Threshold condition validated during the poll count (number of polls): Monitor’s status changes to ”Trouble or Critical” when the condition applied to the threshold value is continuously validated for the specified “Poll count”.
   • Average value during poll count (number of polls): Monitor’s status changes to ”Trouble or Critical”, when the average of the attribute values, for the number of polls configured, continuously justifies the condition applied on the threshold value.
   • Condition validated during time duration (in minutes): When the specified condition applied on the threshold value is continuously validated, for all the polls, during the time duration configured, monitor’s status changes to ”Trouble or Critical”.
   • Average value during time duration (in minutes): Monitor’s status changes to ”Trouble or Critical”, when the average of the attribute values, for the time duration configured, continuously justifies the condition applied on the threshold value.
   
   Multiple poll check strategy will not be applied by default. During the conditions where no strategy could be applied, the threshold breach will be validated for a single poll alone.
   
   To make sure the condition applied on the strategy “Strategy-3: Time duration or Strategy-4: Average value during time duration” for threshold breach detection works as intended, you must ensure that you specify a time duration which is at least twice the applied check frequency for that monitor.
   
   
6. Click Save.

The threshold and availability profile created for the VMWare resource pool monitor will be automatically listed on the Threshold and Availability screen, along with any profiles you've already created.
