Re: Web interface logout

Hello,

Thanks for the info.  It was indeed due to auto password complete.  Is it possible to implement a logout feature?  It's rather difficult to impose a check on each user's IE setting.

Also, a few questions about the following config:

  check system site
    if loadavg (1min) > 5 then alert
    if loadavg (5min) > 5 then alert
    if memory usage > 80% then alert
    if cpu usage (user) > 70% then alert
    if cpu usage (system) > 30% then alert
    if cpu usage (wait) > 20% then alert

   check process apache with pidfile /etc/httpd/run/httpd.pid
    start program = "/etc/init.d/httpd start"
    stop program  = "/etc/init.d/httpd stop"
    if totalmem > 300.0 MB for 5 cycles then restart

Does this check for memory consumped by all of the PIDs executed only by the user apache?  For example, by running "ps aux" I see the following.
root     32042  0.0  4.0  28948 10660 ?        Ss   Jul02   0:00 /usr/sbin/httpd
apache   23652  0.6  6.0  36548 15856 ?        S    21:25   0:30 /usr/sbin/httpd
apache   27802  0.6  6.0  36572 15844 ?        S    21:59   0:17 /usr/sbin/httpd
apache   27879  0.5  6.6  38312 17556 ?        S    22:00   0:15 /usr/sbin/httpd
apache   30138  0.6  6.1  36952 16160 ?        S    22:19   0:11 /usr/sbin/httpd
apache   31989  0.5  6.0  36704 15896 ?        S    22:32   0:05 /usr/sbin/httpd
apache   31991  0.7  5.9  36320 15580 ?        S    22:32   0:06 /usr/sbin/httpd
apache   32000  0.7  6.8  38740 17944 ?        S    22:32   0:06 /usr/sbin/httpd
apache   32033  0.6  6.2  37200 16388 ?        S    22:33   0:05 /usr/sbin/httpd
So in this case, it is not including the first line as it is consumped by the user "root" and should only check if this combined 49.6% memory usage by the user "apache" exceeds 300.0MB?  What I don't understand is, why does the web interface indicate that the process "apache" is using only 4.0% of memory.

Regards,
Titus

Monit uses basic authentication[1] and with this authentication  
scheme there is no logout. Simply close the browser to "logout".

Access to monit's web interface *will* require re-authentication  
after the browser was closed. If you can access the application  
"directly" without authentication it means that you have stored  
username and password with IE's password manager and that IE now  
performs an auto-login in the background. It could also be that you  
are looking at pages cached by IE.
