Charts do not load when querying for data several months old. Charts return "No Data" when querying for data older than 14 days/two weeks.
In some cases, historical data will time out before the chart finishes loading.
If a source stops sending in metrics (data points) for more than 14 days, it is considered "obsolete" and will not be included in the chart results.
To get the data older than 14 days update your Dashboards and Charts to enable Include Obsolete Metrics option. See "Examine Data with Dashboards and Charts" link below.
This option can be configured statically or enabled ad hoc through Dashboard Settings or though the Advance Tab on any Chart.
If you are querying historical data, ingested before year 2025 and the query results are not loading, or for further assistance with data not loading as expected on your Dashboards or Charts, please contact Broadcom Support.
