How do post-process searches work in Splunk?
In my dashboard there are 4 panels. Around 3-4 sub searches are repeating in every panel which resulting performance issue and dashboard not displaying any data.
Using Post-process searches will be helpful in my scenario. Or else please suggest other alternatives.
Without looking at your dashboard and the queries, it is hard to tell. If done right, post process could significantly help dashboard performance. However, there are some limitation you have to be aware of when you design your dashboard.
