check_http plugin does not add :<port> in Host: header

[Jon]

Hello,

Is "son1.rf.rabobank.nl" the actual hostname?  It's tough to get the
check_http working, for me I hardcode it into my checkcommands.cfg.
Basically I have:

check_http -I www.xxx.yyy.zzz www.domain.com

I specify where the actual server is with the IP then the address to do a
GET on the top level.  But I think you then add a more specific path to
check with the -u option.

Have you tried reading the help on check_http?  That's how I figured it out.
Go to the nagios/libexec directory and do a ./check_http -help to get more
information on how to use it.

HTH.

Subject: [Nagios-users] check_http plugin does not add :<port> in Host:
header

Hi,

I'am new to this list, so forgive me any stupid questions.
I'm using nagios 1.2 (feb 02 2004) and I'm trying to monitor applications
running in WebSphere.
I use the following chech_http command:

check_http -H son1.rf.rabobank.nl -p 2210 -u /w5/dws_syst/PingServlet 

This gives a 404 response back, and after diagnosing the WebSphere trace, it
appears that in the HTTP Headers sent by nagios, there is only the host name
and not the port number 2210 (son1.rf.rabobank.nl instead of
son1.rf.rabobank.nl:2210).

In my opinion nagios should append :2210 in the case to the hostname, other
http clients (browsers, JDKs) all do send the proper Host: header ,
including the :port .

Is there a "hidden feature" or a way to get around it (except from changing
the vhost definition on the server) ?

I tried the following command:
check_http -H 'son1.rf.rabobank.nl:2210' -p 2210 -u /w5/dws_syst/PingServlet

But that gives me an "Invalid host name ...." response from the plugin.

This sounds like a bug/restriction in check_http ?

please advise,
regards,
Harry Metske
