Check Apache running on certain IP always returning 0

[cermisch]

Hello,

I am pretty new to Zabbix and still trying to figure out our setup.

I managed to check for SMTP and SSH service using the agent - that was pretty straight-forward. But now I want to check for http and https which only listens to a second IP on te same physical server.

After looking through the manual I came up with these two options:

Using the agent: check_service[http,83.220.131.80,80]
Using simple check: http,83.220.131.80

Both of the above checks always return 0 even though the webserver is running perfectly.

Any ideas what I am doing wrong? Thanks in advance...

btw: we are using Zabbix 1.0 on a suse linux 9.3 system; client is installed on a suse linux 10 with apache2 to be checked...

I might add, that if I setup an own host for this IP in Zabbix and do a simple check http,83.220.131.80 if does return the correct value (1) for Apache.

Any ideas?

can you do a wget for index.html to the offending ipaddress manually from the zabbix server command line?

the problem is solved...

we only opened up port 80 as the destination port on in the firewall. but the agent seems to wir for a response from apache with port 80 as the source port.

so allowing the server ip to contact itself with port 80 as source port solved the problem.
