Adjusting Thresholds & Baselining

Traverse comes with pre-defined thresholds for most metrics, but these warning & critical thresholds might be too low for your environment and require adjustments. If you have a small number of devices, and if you are seeing some devices in warning or critical state for long periods of time, you should click on the devices and increase the thresholds as needed.

  1. Click on Status > Tests from the main menu
  2. Click once on the test name which is in red or yellow state to select that row. Note the current result, and then click on the edit icon on the top right menu.
  3. On the Update Test page, change the warning threshold to be a little higher than the current value for the test that you noted earlier and a matching critical threshold (slightly higher than warning).
  4. Click on the Submit button.
  5. Repeat these steps for the remaining tests which are in warning or critical state.

If you have a large number of devices, you can use the "baselining" feature in Traverse to automatically adjust the thresholds based on the historical data collected. This option is under Administration > Devices > Test Baseline Management.

Adaptive Thresholds

Traverse also supports dynamic, Adaptive Thresholds. This feature allows setting alarm thresholds that match varying patterns of use or load in the IT infrastructure. For example, if nightly back-up jobs increase the utilization levels of a server during the evening hours, then you can set higher threshold levels for this time period so that unnecessary alarms are not generated. Currently you have to enable this on a per test basis. To access this feature for a test:

  1. Select a device and display its tests by going to Administration > Devices > Tests
  2. Then click on the Modify button for a test, and select the Time Based Threshold checkbox.
  3. You can either click on the Configure link if you want to set the thresholds manually, or else you can configure the thresholds automatically using the baselining feature by going to Administration > Devices > Test Baseline Management.
  4. Click on the Submit button.
