After upgrading to Splunk ES version 6.0.0 we got the Investigation Overview dashboard, but we have some problems when running it. If we try to look for investigations far back in time, the searches on the dashboard doesn't work, and they give an error. More specifically, the search | rest splunk_server=local count=0 /services/storage/investigation/investigation all=true earliest="-90d@d" latest="now" gives the error Failed to fetch REST endpoint uri=https://127.0.0.1:8089/services/storage/investigation/investigation [...] from server https://127.0.0.1:8089 [...]. Note, it works fine if we are not looking that far back, it only throws an error if we look for investigations older than a certain time. We don't know if it's the amount of time looking back itself, or if it is a certain investigation that causes the REST call to crash, but either way this looks like a bug to me.
Anyone else have experienced the same issue, or possible have a fix?
We tried fixing the problem by deleting all investigations older than a certain date. This "solved" the problem for a time, but now the problem has reappeared. Again we can use the REST commando to look for investigations older than a certain date. We can't figure out why. It seems like a bug to us.
