Search activity: Instance
What does this view show?
Several panels about search activity.
Interpret results in this view
In the Median Resource Usage of Searches panel, note that:
- Resource usage is aggregated over all searches.
- Memory usage represents physical memory.
- In this chart, CPU usage is expressed in percentage of one core, not as system-wide CPU usage. As a result, you are likely to see values >100% here. This is not the case for other examples of CPU usage in the distributed management console.
In the Aggregate Search Runtime panel, note that:
- For each time bin in the chart, the DMC adds up the runtime of all searches that were running during that time range. Thus, you might see, for example, 1000 seconds of search in 5 minutes. This means that multiple searches were running over the course of those 5 minutes.
- For the modes historical batch and RT indexed, historical batch can be dispatched only by certain facilities within Splunk Enterprise (the scheduler, for example). RT indexed means indexed real-time.
In the Top 10 Memory-Consuming Searches panel, SID means search ID. If you are looking for information about a saved search, audit.log matches the name of your saved search (savedsearch_name) with its search ID (search_id), user, and time. With the search_id, you can look up that search elsewhere, like in the Splunk search logs (see "What Splunk logs about itself").
What to look for in this view
Consider your search concurrency and resource usage compared to your system limits.
For information, see:
- "Write better searches" in the Search Manual.
- "Get started with Search" in the Search Manual.
- "Configure the priority of scheduled reports" in the Reporting Manual.
- "Overview of summary-based search and pivot acceleration" in the Knowledge Manager Manual.
Troubleshoot this view
In the Search Activity panel, the snapshots are taken every ten seconds by default. So if no searches are currently running, or if the searches you run are very short lived, the snapshots panel is blank and says "no results found."
The historical panels get data from introspection logs. If a panel is blank or missing information from non-indexers, check:
