We want to create an alert rule that checks only a small part of the overall system.
This alert is supposed to find all VMs from only the VM cluster DX-Cluster that have a higher memory utilization than 90%.
- (1) The Alert works on VM virtual machines So the object type has to be
Compute / VMware / Resource Consumer / VM Virtual Machine - (2) In the Alert Rule Section, we have 2 selections on VM cluster and VM virtual machine
We have set the Selection Path so that we can apply filters to these 2 levels.
Please note that the natural order is adhered to. Cluster includes VM Virtual Machines and therefore cluster must be made in front of the Virtual Machines.
If necessary, change the order with drag & drop.
BVQ / VM Cluster / VM Virtual Machine - (3) The filter on the cluster name (this could als be name startWith "DC-Cl" or name pattern /DX.*/
name = "DX-Cluster" - (4) Second filter is a restriction to the virtual machine, where we only want to check active machines to avoid unknown results.
power_state = "Powered On"
Do not forget:
- (5) to enable the alert
- (6) decide whether you want to have it visible on SHM
- (7) Determine how often the alert shall be checked
- (8) Do not forget to provide a helping comment
- (9) when using the alert in the SHM you should also add categories
