How to check the indexer status details for last one month from the Search head by using SPL query
@thahir - If you mean status is Indexer server is running or not. You can use this search with a timechart.
| timechart span=1h count
You can update span value as you require.
If you see a gap in the line chart, that means the indexer was down during that time.
I hope this helps!!!
