check_http high response time

Hi,
I have this strange things that I want to understand:
When I execute check_http i get an high response time (from 5 to 15 sec) even if the server is not under high load (under 1) and even if the same page loaded by browser or checked by "ab" i get response time under one second.
Here is some example:
Code: Select all
check_http -vvv -N -t 30 -H www.caseinlegnobernardidasolo.it
GET / HTTP/1.1
User-Agent: check_http/v1.4.16.29.g3c10.dirty (nagios-plugins 1.4.16)

You can try the browser response time by yourself (firebugs give me 0.9 sec)
Can someone explain me this? It's very frustrating, how can I solve it?

My result was:

I would guess that your Nagios host either has a very lengthy path, or some firewall is seeing your constant banging against the web server and rate limiting you as a result.
What is the output of:
Code: Select all
ping -c 5 www.caseinlegnobernardidasolo.it
traceroute www.caseinlegnobernardidasolo.it

obviusly there's a firewall (10.0.0.1) but I think it doesn't filter nagios server because, as I sayd before, "ab" works well.

How often are your Nagios checks? Does your ab check occur on regular intervals as well? And does the target machine have a firewall running on it like iptables? If so, I would love to see the output of:

In this case Check interval is 15 minutes
Max Check Attemps: 5
Retry Interval: 2

No, I used ab only to make some tests.

Yes, there's a firewall. The Nagios server public static IP is 95.226.98.234, while the server is 46.252.192.11

Thank you. It will take me a bit to chew through your iptables results, but I do see some limit statements that log to syslog. Is there anything in /var/log/messages with "Firewall" in it that look obviously connected to either traffic from your Nagios host or traffic to your web server?

No output from
Code: Select all
cat /var/log/messages | grep 95.226.98.234
A lot of output from
Code: Select all
cat /var/log/messages | grep Firewall
but nothing from Nagios server.
Here is some example (don't look at the time: different timezone):

Does the delay happen when you go to other web sites? And what version of check_http are you running (check_http -V)?

It seems thats the problem is between the server and internet...
The version of check_http is: check_http v1.4.16.29.g3c10.dirty (nagios-plugins 1.4.16)

I agree. I see nothing wrong with the iptables or anything else, so I am guessing that it is something specific to your server or the network that it is plugged in to. Unfortunately, I do not think there is going to be much additional help to you here, so you may want to talk with your network administrator - unless that is you!!
