Record traffic to web server when it goes down. 1

[ChrisH2]

Hello,

I have no idea if this is the correct section to post this but here goes.
I have a problem with a web server. Being a programmer and not a networking person, I am having difficulty solving the problem so please bare with me.
I have a 8 port VPN firewall router. Plugged in the router is a appache web server, a windows pc and a sco server. Everything runs fine including vpn except for the web server. The web server/site goes down every 20-30 mins, it lasts for 2-3 mins at a time and then springs back to life. By going down I mean users of the site get web page not found.
In the router config it is forwarding HTTP service to the local IP of the web server.
I want to be able to record traffic to and from this web server whilst the site goes down. I have been told that I should use a sniffer on my network.
Can anyone recommend how I should go about resolving this.
Can a sniffer be used anywhere on the network to record this information?

Any help would be much appreciated as I am pulling out what little hair I have left.

Thanks

If you don't understand networking protocols fairly well a sniffer is not going to help you much. They simply report what is happening, it is up to you to analyze the recordings and derive information from them.

A sniffer must be on the same physical network segment as the data you wish to examine. Where you place one depends entirely on your network layout.

Are there no errors on the server itself?
