[users@httpd] debugging mod_proxy performance with WireShark
Hi all-
I am new to Apache httpd and have gotten about as far as I can debugging
some performance problems we are having on a machine. It is a VM with
Fedora 13 installed. I am running a stand alone JIRA Tomcat installation on
port 8080 and running httpd with mod_proxy as a reverse proxy on the same
box. If I remove the httpd layer and go directly to Tomcat the performance
is normal. When I add the httpd layer it slows down overall and hangs
dramatically fairly often. I installed Wireshark and have captured some
requests but I'm not really sure what I'm looking for. How can I tell
what's going on in the time between some of the traffic going on? I also
configured Flood but that doesn't seem to offer me any insight into what is
causing the problem either. I'm likely not using these tools quite right
but I can't seem to find out what I should be looking for.
Here are my two VHosts. I am redirecting to HTTPS also, but if I take that
layer out, it still has performance issues.
<VirtualHost *:80>
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
</VirtualHost>
<VirtualHost 192.168.XXX.XXX:443>
#<VirtualHost 192.168.XXX.XXX:80>
ServerName 192.168.XXX.XXX
ProxyRequests Off
ProxyPreserveHost On
SSLEngine On
SSLCertificateFile /etc/httpd/ssl/jirassl-pem.crt
SSLCertificateKeyFile /etc/httpd/ssl/jirassl.key
ProxyPass / http://localhost:8080/
ProxyPassReverse / http://localhost:8080/
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
</VirtualHost>
Any suggestions insight into where i can find info to help me learn to debug
issues with httpd in general would be greatly appreciated.
Thanks all
