NAME
httping - measure the lateceny and throughput of a webserver
SYNOPSIS
httping [options]
options: [-g url] [-h hostname] [-p portnumber] [-x proxyhost:port] [-c count] [-i interval] [-t timeout] [-s] [-G] [-b] [-L xferlimit]
[-X] [-l] [-z] [-f] [-m] [-o rc,...] [-e string] [-I useragent string] [-R referer string] [-r] [-n warn,crit] [-N mode] [-q] [-V]
DESCRIPTION
The program httping lets you measure the latency of a webserver. Since version 1.0.6 also the throughput can be measured.
OPTIONS
-g url This selects the url to probe. E.g.: http://localhost/
-h hostname
Instead of '-g' one can also set a hostname to probe with -h: -h localhost
-p portnumber
-p can be used together with -h. -p selects the portnumber to probe.
-x proxyhost:port]
Probe using a proxyserver. Note that you're also measuring the latency of the proxyserver!
-c count
How many probes to send before exiting.
-i interval
How many seconds to sleep between every probe sent.
-t timeout
How long to wait for answer from the other side.
-S Split measured latency in time to connect and time to exchange a request with the HTTP server.
-s When a successfull transaction was done, show the HTTP statuscode (200, 404, etc.).
-G Do a GET request instead of a HEAD request: this means that also the complete page/file must be transferred. Note that in this case
you're no longer measuring the latency!
-b Use this switch together with '-G'. When this option is used, the transferspeed (in KB/s) is shown.
-B Use this switch together with '-G'. Ask the HTTP server to compress the returned data: this will reduce the influence of the band-
width of your connection while increasing the influence of the processorpower of the HTTP server.
-L x Use this switch together with '-G'. Limit the amount of data transferred to 'x'. Note that this only affects the content of the
page/file and not the headerdata.
-X Use this switch together with '-G'. For each "ping" show the amount of data transferred (excluding the headers).
-l Connect using SSL: for this to work you need to give a 'https'-url or a 443 portnumber.
-z When connecting using SSL, display the fingerprint of the X509 certificate(s) of the peer.
-a Audible ping
-f Flood ping: do not sit idle between each ping but ping as fast as the computer and network allow you to.
-m Show machine readable output (also check '-o' and '-e').
-o x,x,...
This selects the HTTP status-codes which are regarded as an OK-state.
-e str When the status-code differs from the ones selected with '-o', the given string is displayed.
-I str UserAgent-string to send to the webserver (instead of 'HTTPing <version>').
-R str Referer-string to send to the webserver.
-r Only resolve the hostname once: this takes the resolving out of the loop so that the latency of the DNS is not measured. Also use-
full when you want to measure only 1 webserver while the DNS returns a different ip-address for each resolve ('roundrobin').
-n warn,crit
Switches HTTPing to Nagios-plugin mode 1: return exitcode '1' when the average response time is bigger then 'warn', return exitcode
'2' when the the average response time is bigger then 'crit'. In all other cases return exitcode '0'.
-N x Switches HTTPing to Nagios-plugin mode 2: return 0 when everything is fine, 'x' when anything fails. E.g.: 1 => Nagios warning
state, 2 => Nagios critical state.
-q Be quiet, only return an exit-code.
-A,U,P Activate the basic authentication, Username follow the -U, Password the -P.
-V Show the version and exit.
KEYS
Press <CTRL> + <c> to exit the program. It will display a summary of what was measured.
EXAMPLES
httping -g http://localhost/
Ping the webserver on host 'localhost'.
httping -h localhost -p 1000
Ping the webserver on host 'localhost' and portnumber 1000.
httping -l -g https://localhost/
Ping the webserver on host 'localhost' using an SSL connection.
httping -g http://localhost/ -A -U username -P password
Ping the webserver on host 'localhost' using the Basic HTTP Authentication.
BUGS
None. This program is totally bug-free.
