Adjust threshold settings and apply baseline data

Updated:  October 31, 2017

In general, baseline data is calculated on demand; however, seven days of data is the recommended minimum amount of data needed for baseline calculations to be considered accurate.

Baseline data for macros, such as  ${USE_BASELINE}, are automatically calculated during nightly database maintenance.

After thresholds are calculated and applied to component monitors, the thresholds remain static until manually re-applied. This is not a moving baseline that is calculated nightly based on the last seven days of data. A moving baseline would mask data spikes and other anomalies that need to be highlighted.

Thresholds set manually may yield more desirable results if you are familiar with the nuances of your environment.

How SAM calculates the baseline

SolarWinds SAM calculates the baseline using the following macros:

Macro Description
${USE_BASELINE} Currently used baseline in SAM, used in threshold fields of SAM component monitors. Recommended baseline values are calculated using the following formulas:

Warning: ${MEAN} + 2 * ${STD_DEV} (or ${MEAN} - 2 * ${STD_DEV})

Critical: ${MEAN} + 3 * ${STD_DEV} (or ${MEAN} - 3 * ${STD_DEV})

Baseline thresholds are not suitable for all metrics. If the calculated values do not meet your expectations, consider setting the thresholds manually.

${USE_BASELINE} does not support math functions. To adjust the baseline calculation, replace ${USE_BASELINE} with the formulas above and change the calculation as necessary. 

${MEAN} Current Mean or Average. You can use this macro with math functions in threshold fields.
${STD_DEV) Standard Deviation. You can use this macro with math functions in threshold fields.

Change the amount of data used in baseline calculations

You may need to log in with an administrator account to perform this action.

  1. On the Web Console, click Settings > All Settings > SAM > Settings > Data & Database Settings.
  2. Enter a number of days, and then click Submit.

The value for the Baseline Data Collection Duration field cannot exceed the value defined for the Detail Statistics Retention field (located at the top of the Data & Database Settings section).

Apply baseline thresholds at the template level

You may need to log in with an administrator account to perform this action.

  1. On the Web Console, click Settings > All Settings > SAM Settings > Manage Templates.
  2. Check a template and click Edit from the toolbar.
  3. If selecting only one component monitor, click [+] to expand the monitor details.
    1. Click Use Latest Baseline Thresholds, as shown:

      Once this box is checked, the Warning and Critical fields automatically populate with the macro, ${USE_BASELINE}.

    2. Select the options for sustained thresholds as needed:
  4. If selecting more than one component monitor, select monitors by checking the boxes next to their names.
    1. Click Multi-Edit.

      Multi-Edit only becomes available when the selected component monitors are of the same type.

    2. Check Statistic Threshold on the pop-up window, then check the Use thresholds calculated from baseline data.

      The Use thresholds calculated from baseline data check box does not become available until Statistic Threshold has been checked. Once Use thresholds calculated from baseline data is checked, the Warning and Critical fields automatically populate with the macro, ${USE_BASELINE}.

  5. Click Save, then click Submit.

Apply baseline thresholds at the application level

You may need to log in with an administrator account to perform this action.

  1. On the Web Console, click My Dashboards > Applications > Summary.
  2. From the All Applications resource, expand the tree and then click an application.
  3. From the Application Details resource, click Edit Application Monitor.
  4. If selecting only one Component Monitor, click [+] to expand the monitor details.
    1. Click Override Template.

      The current values for the thresholds appear in the Warning and Critical fields.

    2. Click Use Latest Baseline Thresholds, as shown:
    3. When applied, the values change and a blue icon indicates that baseline thresholds are being used.
  5. If selecting more than one component monitor, use the check boxes to select the monitors you want to edit.
    1. Click Multi-Edit.
      Note: Multi-Edit only becomes available when selected component monitors are of the same type.
    2. Check the Statistic Threshold check box on the pop-up window, then check the Use thresholds calculated from baseline data.

      Once the second box is checked, the Warning and Critical fields automatically populate with the macro, ${USE_BASELINE}.

  6. Click Save, then click Submit.

Use latest baseline details

You may need to log in with an administrator account to perform this action.

  1. On the Web Console, click My Dashboards > Applications > Summary.
  2. From the All Applications resource, expand the tree and then click an application.
  3. From the Application Details resource, click Edit Application Monitor.
  4. Find a component monitor in the list and click [+] to expand the monitor details.
  5. Click Override Template, then click Latest Baseline Details.

Edit capacity planning thresholds

You may need to log in with an administrator account to perform this action.

  1. On the Web Console, click a node to navigate to the Node Details page for that node.
  2. In the Management resource, click Edit Node.
  3. Click Manage Orion General Thresholds to display Capacity Planning options under each object:

  1. Make your selections, then click Submit on both the Orion General Thresholds screen and the Edit Properties screen.
