I have a search tracking users logging into our juniper vpn

sourcetype="SSLVPN" Action="- Login succeeded" |eval Username=lower(Username) | stats sparkline first(LoginTime) as LastLogin count by Username | sort -count | head 10

Everything works perfect when it is set to last 24 hours but when I change the timeline to 30 days (the default) the first value of LastLogin is wrong on half the users, the count is correct but first is dropping off the last 24 hours worth of logins

it is related to username=lower(Username) I am using this because users sign in as Jimmy.zio and jimmy.zio both work and I am aggregating the users into 1

The first command returns the first value in the events list. So if the "first" event is 7 days ago, it will show that one. first and last are not chronological commands, they are based on the input order of the events. Instead, try this, which uses the latest command:

sourcetype="SSLVPN" Action="- Login succeeded" |eval Username=lower(Username) | stats sparkline latest(LoginTime) as LastLogin count by Username | sort -count | head 10
