Platform Notice: Server and Data Center Only. This article only applies to Atlassian products on the server and data center platforms.
As an administrator of Jira Server / Data Center, it can be helpful to see a list of log files Jira creates and their locations, particularly for ingress into a log monitoring solution such as Splunk.
The following table lists the log files Jira creates and their default location and filename.

log4j.properties file (located in the Jira application installation directory).
