#Splunk tstats command manual#
A namespace created using “tscollect” search command.Tstats executes on the index-time fields with the following methods: (i.e., only metadata fields such as source type, host, source, and _time). Tstats are faster than stats, as tstats looks only at the indexed metadata, .tsidx files. And for the next iteration, it’s taking the previous value into account. In the above example, it’s computing the sum of the “status” value concerning “method”.
This command utilizes events before the current event to evaluate the aggregate statistics that are applied to individual events. Streamstats assist in aggregating statistics in a streaming manner similar to eventstats. It clusters the statistics to the original data, thus all of the original data becomes available for further calculations. In the above example, you can see the newly created field “count” as well as the original fields such as “log_level” and “class”. When we get some results using stats command, Splunk won’t know the native fields and hence it displays only the fields that are included in results. But the only difference is, it does not generate statistical results rather it aggregates them with the original raw data. This calculates a statistical result similar to stats command.
In the above example, stats command returns 4 statistical results for “log_level” field with the count of each value in the field. Various statistical functions are available such as sum(), avg(), count(), sumsq(), distinct_count(), median(), stdev(),etc. You will use stats command more often although it has a couple of siblings named eventstats and streamstats. When you call it with a by-clause, it produces one row for each distinct value of the by-clause. When you call it without a by-clause, it produces one row which depicts the aggregation of the entire incoming result set. It calculates comprehensive statistics over the dataset that is similar to SQL aggregation. What are the Different Types of Stats C ommands? The stats command perform on the search results on the whole and it returns only the fields that you mention. These are derived from events that are retrieved from an index. The purpose of statistics or stats commands is to calculate summary statistics on the search results. So let’s find out how these stats commands work. These are indeed challenging to understand but they make our work easy. Īs an analyst, we come across many dashboards while making dashboards, alerts, or understanding existing dashboards. The main commands available in Splunk are stats, eventstats, streamstats, and tstats. This post is to explicate the working of statistic command and how it differs.
