I see similar issues with a search where the from clause specifies a datamodel. Spoiler. When you run a tstats search on an accelerated data model where the search has a time range that extends past the summarization time range of the data model, the search will generate results from the summarized data within that time range and from the unsummarized data that falls outside of that time range. action,Authentication. Hi. Here is a basic tstats search I use to check network traffic. Required fields. Hello, I am creating some reports to measure the uptime of hardware we have deployed, and I need a way to filter out multiple date/time ranges the match up with maintenance windows. I can't find definitions for these macros anywhere. tag . The summariesonly option tells tstats to look only at events that are in the accelerated datamodel.
