Changing Host Header
list Thomas Seglard
Hello, First of all, I'm using Xymon 4.2.3 J I want to get the Apache performance graphs but to achieve that I need to send a specific host header due to my Apache configuration. This command is working thanks to curl : xymonServer:$ curl -H"Host: localhost" http://prdwatweb016:8090/sstatus If I specify any other host, I couldn't get the Apache status. So my question is : how can I do that with Xymon ? Sincerly, Thomas S PS : oh and I really appreciate the new version, that's so great work. I'm really waiting for this one J

Use "apache=http://prdwatweb016:8090/sstatus"; and make sure "prdwatweb016" resolves to the right IP. Worst case, add an entry to your Xymon servers' /etc/hosts file for it. (With ordinary http checks, you could specify the IP to use as http://prdwatwab016=127.0.0.1:8090/sstatus but I'm not sure if that works for the "apache" test). Regards, Henrik

Hi Henrik, Thanks a lot for answer but none of your solutions work. Basically, I have 30 webservers running Apache and the only way to have their "server status" statistics is putting a header "Host: localhost". When I'm using "apache=http://prdwatweb016:8090/sstatus"; within Xymon configuration, I can see in prdwatweb016's Apache logs that Apache can't get access to /sstatus due to server configuration meaning that it doesn't have the specific header. I can't modify the Apache's configuration due to our security policy but I can make a little script to get the stats on each server. The main problem is that I don't know how to send these stats to Xymon Server to be analyzed and graphed properly... Maybe I'm not asking the correct question :) Please feel free to correct me or ask for more infos. Sincerly, Thomas S

The equivalent of your "curl" command
xymonServer:$ curl -H"Host: localhost" http://prdwatweb016:8090/sstatus
would be 10.0.1.1 prdwatweb016 # apache=http://localhost=10.0.1.1:8090/sstatus assuming your "prdwatweb016" server has IP 10.0.1.1. But using "localhost" with a non-127.x.x.x IP just doesn't sound right :-) Regards, Henrik
