How can I get the list of all users who logged into JIRA & confluence only in last 3 months.

a) What Daniil said. More info:

b) JIRA allows you to activate a detailed log of who accessed what.

Probably you could get such information into atlassian-jira-security.log. Perhaps it is better to use some parser.
