splunk environments with High CPU usage
@kiran_panchavathas some good suggestions. Also consider using post-processing and/or saved searches in the dashboards to reduce CPU usage and speed up the dashboards.
Certainly! Addressing high CPU usage in your Splunk environment due to specific dashboards can be challenging, but let’s explore some strategies to mitigate the issue:
Dashboard Optimization:-
Review Dashboard Components:
Inspect each dashboard panel. Are there any resource-intensive visualizations (e.g., complex charts, tables, or maps)? Simplify or optimize them.
Reduce Real-Time Updates:
If dashboards update in real-time, consider increasing the refresh interval. Frequent updates can strain CPU resources.
Limit Concurrent Sessions:
Since users have multiple sessions open, limit the number of concurrent sessions per user. Excessive sessions can overload the system.
Use Summary Indexes:
Consider using summary indexes for frequently accessed data. This reduces the need for real-time searches.
Monitoring and Troubleshooting:
Splunk Monitoring Console (MC): Use MC to monitor resource usage. Check the CPU Usage by process class graph to identify which components consume the most CPU.
