Issue/Introduction
Querying data older than 14 days or a time series that stopped reporting for longer than 14 days are not included in query results due to the exclusion of "Obsolete Metrics".
A primary goal of DX OpenExplorer (formally Wavefront) is to provide end users with fast, real-time answers to their data questions. Since no data is deleted during its retention period, one of the ways we accomplish this is by only scanning relevant and recent data by default.
If the metric or time series begins to report in again after being marked as obsolete the data is no longer marked as obsolete and will be included in query results.
Cause
When a metric or time series stops reporting data and hasn't reported at least one data value within a 14 days period it is considered "obsolete" in OE. By default, obsolete data is not scanned or rendered in order to promote optimal query performance for real-time data.
Resolution
If you see no data or inaccurate data in your chart/dashboard, when viewing a time window more than 14 days in the past, update the Chart or API call to include obsolete metrics.
In the UI enable the “Include Obsolete Metrics” property in your chart (Under Advanced tab) as shown below.
If you are programmatically querying via REST API or a GO client, ect, then add includeObsoleteMetrics=true parameter in your api call.
For example:
https://your_cluster.wavefront.com/api/v2/chart/api?q=my_query&s=start_time&e=end_time&includeObsoleteMetrics=true&<optional other parameters>
After enabling Include Obsolete Metrics, if you continue to not return the expected results, please open a support ticket via Support@Broadcom Portal.
