SSL VPN Last Login User Report

[Dylan]

I am trying to build a dataset to pull the last time each user has logged in. Best I have been able to get is a report showing each login, but I don't know how to remove the extra (older) dates. Below is the current Dataset I have built.

SELECT UPPER(`user`) AS user_src, IPSTR(`remip`) AS remote_ip, TO_CHAR(TO_TIMESTAMP(`itime`)::timestamp, 'YYYY-MM-DD HH24:MI') AS time FROM $log WHERE $filter AND `tunneltype`='ssl-web' AND `action`='tunnel-up' GROUP BY user_src, remote_ip, time ORDER BY user_src, time desc
