does anybody knows what this means? ptymonitor: pam_unix(login:session): session opened for user root by (uid=0)

Hi, today I got these messages in /var/log/secure that enabled an alert in my monitoring tool:

Aug 1 14:52:02 xxxxxxxxxxxx ptymonitor: pam_unix(login:session): session opened
for user root by (uid=0)
Aug 1 14:52:02 xxxxxxxxxxxx ptymonitor: pam_ck_connector(login:session): cannot
determine display-device
Aug 1 14:52:02 xxxxxxxxxxxx ptymonitor: pam_unix(login:session): session closed
for user root

Does anybody knows what this means?
I don't see any hardware or software failures in the log files.

PD: xxxxxxxxxxxx is the server name

Im using RH 6.5

This means you logged in as root. PAM is just logging the logins of root user. It's not an error.

Thank you!

Do those times match with when you logged in? By the way, consider making a common user a sudoer.
