![]() It's therefore much much faster but limited only to those indexed fields. Similar to the stats command, tstats will perform statistical queries. It has no knowledge of search-time extracted fields. You can compare TSIDX with a columnar data base. The standard splunk's metadata fields - host, source and sourcetype are indexed fields.īoth types of fields have their pros and cons and you usually need a very good reason to create new indexed fields.īut coming back to the original issue - doing summary statistics using tstats is possible only over indexed fields since tstats doesn't touch raw events and only uses the summaries of indexed fields. The tstats command allows you to perform statistical searches using regular Splunk search syntax on the TSIDX summaries created by accelerated datamodels. Id like to convert it to a standard month/day/year format. However, in using this query the output reflects a time format that is in EPOC format. So once the event is indexed, all indexed fields possible for that event are created and written into separate files. Is there a way to use the tstats command to list the number of unique hosts that report into Splunk over time Im looking to track the number of hosts. Im running the below query to find out when was the last time an index checked in. dll files or executables at the operating system to generate the file hash value in order to compare it with a 'blacklist or whitelist' Also does Splunk provide an Add-on or App already that handles file hash value generation or planning to in the near future, for both Windows and Unix. Those fields are created only once during the initial ingestion of events. What app was used or was Splunk used to scan for specific. Then there is the second one - the indexed fields. remove table time, raw as here you are considering only two fields in results and trying to join with host, source and index or you can replace that with table time, raw, host, source, index Let me know if it gives output. Im trying to use tstats from an accelerated data model and having no success. ![]() Since they are extracted during search time, you can modify the extraction definitions and get various fields from the same raw events, you can redefine the extractions and reapply the, to the same raw data and so on. The indexed fields can be from indexed data or accelerated data models. There are the "usual" fields which are extracted in search time which means that splunk extracts them from raw events on the fly as it's comparing the events to your given conditions (oversimplifying slightly the process). Use the tstats command to perform statistical queries on indexed fields in tsidx files.
