You may not think this is necessary, but in large Splunk environments, even basic maintenance tasks like rebooting a server or upgrading an app can have unforeseen consequences. The final search is:Įventtype="splunkd-log" (log_level=WARN OR log_level=ERROR OR log_level=FATAL) component!=DispatchManagerĪs a matter of course, this search (with the addition of a host clause) should be run whenever a change is made. You may want to create a separate search with component=DispatchManager to monitor user quotas. I don't really feel this is a splunkd warning as much as a user warning, so I filter these out of the query. This search will include dispatch manager warnings for when users exceed their quotas of concurrent searches. So, to get the important events, you can use the query:Įventtype="splunkd-log" (log_level=WARN OR log_level=ERROR OR log_level=FATAL) Debug is turned off by default and Info describes expected events. The splunkd.log has five log levels: DEBUG, INFO, WARN, ERROR, and FATAL. To limit our search to just important events, you need to specify the desired log level in our SPL. That simplifies the SPL for all your splunkd log events from all servers and forwarders to: eventtype="splunkd-log". Index=_internal source=*/splunkd.log OR source=*\\splunkd.log Luckily, Splunk comes with a pre-defined event type for splunkd.log (eventtype="splunkd-log") which is defined as: For example, the Windows Universal Forwarder is stored in splunkd.log:Ĭ:\Program Files\SplunkUniversalForwarder\var\log\splunk\splunkd.logīut, on a Linux computer running Splunk Enterprise, the log is at: Source is also problematic because the location (and therefore source) of the splunkd.log varies depending on product and OS. Sourcetype is more complicated, because while there is a splunkd sourcetype, there are five other logs (splunkd_access.log, splunkd_stdout.log, etc.) that share this sourcetype. The easy part is setting the index since all Splunk's internal logs are conveniently kept in the _internal index. The SPL to query the splunkd logs is a bit more complicated than it probably should be. The most critical log to master is splunkd.log which logs events for the splunk daemon.
The challenge for the Splunk administrator is getting a handle on these logs and using them to troubleshoot issues, find unknown errors, and improve performance.

These logs don't consume license usage, so other than disk space, there is no downside to all this logging, and the information the logs provide can be eye opening. The current version of Splunk Enterprise (v 8.05) generates 22 different logs (for a complete current list see: What Splunk logs about itself). Splunk is great about logging its warnings and errors, but it won’t tell you about them – you have to ask!Īs the leading machine-generated data analysis software, it’s not surprising that Splunk excels at creating robust logs.
