THRESHOLD - DESCRIPTOR PATTERNS

The default thresholds set for a test will automatically apply to all descriptors supported by the test. Sometimes however, administrators may want to define the same threshold values for a group of closely-related descriptors. For instance, consider a virtualized environment where the first three letters of the VM name represent the operating system of the VM - lin for Linux VMs, win for Windows VMs and so on. In such an environment, the administrator may want to configure the same upper and lower bounds of performance for the ESX VM Details test of all the Windows VMs alone - i.e., for all VMs with names that begin with win. To achieve this, the administrator can quickly define a descriptor pattern that groups all VMs that begin with win and can configure thresholds for that pattern, so that the threshold settings govern all those descriptors that match the configured pattern - in thise case, the Windows VMs.

For defining a descriptor pattern and configuring its default thresholds, select the Descriptor option from the Default sub-menu of the Thresholds menu in the Alerts tile of the eG administrative interface. This will open the DESCRIPTOR PATTERNS page. If descriptor patterns have already been defined and their thresholds configured, this page will list those patterns. You can modify the threshold configuration of any of the existing patterns by clicking the button that corresponds to that pattern, or click the button to remove a pattern and its threshold specifications.

If you want to see a specific descriptor pattern and its relevant tests, you can do it by entering name of that descriptor pattern in the Search text box. This will list out the specific descriptor pattern along with the test names.
