I wonder what tools are available for Apache Monitoring. I am using this server with busy site for more than year. When it comes to real big traffic (relatively), it's begin to be so slow... It's fronting Tomcat, so I can confirm it's not Tomcat is the reason (site on tomcat port directly works like a breeze). I have even deployed second Apache for static content, but it didn't help a lot.
The only tool I know is jkstatus - but there I cannot see any problem - request number is 10-30 which isn't really big number when I set conf like this:
ThreadLimit 15000
ThreadsPerChild 3000
MaxRequest value sometimes shows like 400-800, but it's only a peak.
Apache logs also don't tell much, no errors, no hints.
How can I get any clue what is going on? |

it helps to monitor the status page e.g. http://httpd.apache.org/server-status
Also monitor the system it self ( CPU,RAM,I/O (disc usage,swap). For that tools like cacti or nagios or htop can help a lot.
is the networking fast enough? Connection from apache to tomcat gigabit, if not on localhost. Connection to the internet good enough?
Once I had an issue with a server, cause the network switch had only 100 Mbit = 12,5 MB/s that is often not enough when many users access the server. |
