On the system side, you could start with /var/log/messages
(it's big but it is time-stamped so it's easy to see what may have happened around the time people were complaining about).
is worth a look, so is /var/log/syslog
(they are also time-stamped).
If you're running big data bases, you might want to look at /var/log/postgresql-9.3
(or whatever version you're using). If you're using MariaDB/MySQL, look for a file named systerm_name.err
, where "system_name" is the name of your system. If you don't know its name,
will show you that.
MariaDB/MySQL is installed in /var/lib/mysql
, you're may (and probably will) vary, so look for that ".err" file.
Keep in mind that if you're doing big updates or inserts in a data base they can take time and a web page may sit there for a few or many seconds while that's taking place.
Then go look at the logs in /var/log/httpd
(that may be different on your system). The file names are access_log
. Look for them if they're not in /var/log/httpd
When I say "look for them," that means use the find
utility or the locate
When I say "look at them," that means look at them in an editor; e.g., vi
Hope this helps some.
