Your first search is semantically equivalent to this tstats provided that all values of the field processName are extracted from key-value pair with equal sign :, splunk tstats.

Similar to the stats command, tstats will perform statistical queries on indexed fields in tsidx files. Significant search performance is gained when using the tstats command, however, you are limited to the fields in indexed data, tscollect data, or accelerated data models. This search took almost 14 minutes to run. This can be helpful when determining search efficiency. The EPS for this search would be just above thousand, a respectable number.

Since tstats can only look at the indexed metadata it can only search fields that are in the metadata. Since status and username are not index-time fields they are search-time.

One of the aspects of defending enterprises that humbles me the most is scale. Enabling different logging and sending those logs to some kind of centralized SIEM device sounds relatively straight forward at a high-level, but dealing with tens or even hundreds of thousands of endpoints presents us with huge challenges. In this post, I wanted to highlight a feature in Splunk that helps — at least in part — address the challenge of hunting at scale: data models and tstats. A data model is a hierarchically structured search-time mapping of semantic knowledge about one or more datasets. It encodes the domain knowledge necessary to build a variety of specialized searches of those datasets.

Since tstats can only look at the indexed metadata it can only search fields that are in the metadata. Since status and username are not index-time fields they are search-time. First, run a simple tstats on the DM doesn't have to be accelerated to make sure it's working and you get some result:.
