What does different log files capture in Jira?

[Aditya Verma]

Why we have different log files in Jira, what kind of logs each log file below captures?

atlassian-jira.log 

atlassian-greenhopper.log

atlassian-jira-http-access.log     

atlassian-jira-http-dump.log     

atlassian-jira-security.log     

atlassian-jira-sql.log

atlassian-jira-incoming-mail.log    

Also, Is there any particular file in which logs for API calls made from JIRA to other applications are captured?

Thanks in Advance.

Look for and in log4j.properties. This is where the java classes individual logging is redirected to one or more outputs.

The defaults (i.e what goes where) i leave to Atlassians docs to explain.
