check_http_fwb

check_http_fwb is a nagios plugin for checking HTTP. It differs from check_http by missing features which are rarely used, having a small codesize (7 KB statical code, diet-compiled and sstripped) and doing per default only a HEAD request.

check_http_fwb -I ip-address -w warnlevel -c critlevel [-p port] [-H http11_hostname] [-u remotefile] [-A user_agent] [-t timeout] [-G] [-D]

Options:

-I ip-address
Specify the IP address of the remote server to check.

-w warnlevel
Specify the warning level.

-c critlevel
Specify the critical level.

-p port
Specify the port of the http server on the remote host.

-H http11_hostname
Specify the hostname for name-based virtual hosts.

-u remotefile
Instead of using the default “/“ you can request a different file.

-A user_agent
Specify the HTTP user agent (default: „check_http_fwb/1 (nagios-fwb)“).

-t timeout
The plugins internal timeout in seconds (default: 10).

-G
Use „GET“. „HEAD“ is the default in check_http_fwb and „GET“ is the default in standard nagios plugin check_http.
