Issue/Introduction

We are trying to query historical data for the past 2 weeks but nothing is showing.

Environment

Wavefront SAAS

Cause

Obsolete Metrics

If a metric stops sending data points for a certain period of time (obsolescence period), it becomes obsolete.

 Note: The obsolescence period for metrics and sources (by default 2 weeks) might vary because it depends on the configuration of your cluster. You can see your current configuration by looking into the Advanced settings of any chart or dashboard. To change this configuration, contact Technical Support.

In the Metrics browser and Query Editor, obsolete metrics are no longer shown in the autocomplete drop-down lists.

 

By default, obsolete metrics are not included in the charts unless you explicitly decide to include these metrics. You can:

• Explicitly include obsolete metrics for each chart.
• Explicitly include obsolete metrics on a dashboard level. This way, obsolete metrics will be included in all the charts within a dashboard.

 Note: Including obsolete metrics on a dashboard level may significantly slow down the dashboard performance.

Resolution

To include obsolete metrics for a chart:

1. Open the chart for edit.
2. Click the Advanced tab and select the Include Obsolete Metrics check box.
3. Explore the data or, if you have Dashboard permissions, click Save to save the changes for this chart.

To include obsolete metrics for a dashboard:

1. Navigate to a dashboard and click the ellipsis icon in the top right corner of the dashboard.
2. Select Edit.
3. Click Settings.
4. Click Advanced and select the Include Obsolete Metrics check box.
5. Click Accept and explore. If you have Dashboards permission click Save to save your changes.

To exclude obsolete metrics for a dashboard:

Dashboards on which inclusion of obsolete metrics is turned on have a warning banner which allows you to easily turn off that setting. 

1. Navigate to the dashboard and click View Settings in the banner at the top. Refresh your browser if you closed the banner.
2. Click Advanced.
3. Deselect the Include Obsolete Metrics check box.
4. Click Accept and explore. If you have Dashboards permission click Save to save your changes.
