It's in libwww-perl, aka. LWP. 

 http://search.cpan.org/~gaas/libwww-perl-5.808/

I'll add this to the docs.

Cheers,

Re: Can't locate HTTP/Request.pm

Hi Niko,

I thought LWP was part of the normal perl distro ... maybe it is
unbundled on freebsd and needs to be installed explicitly ?

cheers

No, it's separate on Debian too, and it's not listed in the
'Perl Core Modules' at perldoc.perl.org.

Re: Can't locate HTTP/Request.pm

Cool, found it.  FYI for FreeBSD users - it's in the www category of ports,
not Perl5.

Tobi,
Cisco is ok so far... I've tried increasing forks but load average of 
the box is rising fast (as expected)

Are you talking about the slave/master setup? How would that help?

this depends on where your load is comming from ... 800 targets
should realy be no problem ... so my guess is, it is a latency
issue with the ciscos not sending pings as fast as fping is able to
... so if you had fping in remote locations you could probably
achieve lower pinging latency ...

just guessing

unfortunately, CiscoRTTMonEchoICMP is used and there's no (easy) way 
around that for the time being...
thanks anyway

curl and websites

Hello

I would like to monitor a website using the curl probe.

As far as I can see the curl probe only monitors a single target (e.g. index.html) but I would like to monitor the total website loading time including images etc.

Is there an easy way to accomplish this?

Regards
MKS

I do not think there is a ready-made solution (it is more complicated
than it appears: because of things like the <object> element or HTTP
content negociation, the total size depends on the client).

I developed a program to do it, but it is no longer maintained and
quite incomplete:
