Measures HTTP roundtrip times (web servers and caches)

Hello there:

I am currently using smokeping to measure the http rrt on my uni network. However, I am having few problems
with echoping at the moment. I am just wondering is there anybody doing similar monitoring as well? I am
running a fping monitoring right now. I have 100% avg pack loss and this really worries me. This is the
config file which is running fping:

*** Probes ***

+ FPing

binary = /usr/local/sbin/fping

*** Targets ***

probe = FPing

menu = Top
title = Network Latency Grapher
remark = Welcome to the SmokePing website of xxx Company. \
         Here you will learn all about the latency of our network.

+ UK

menu = United Kingdom
title = United Kingdom
host = www.yahoo.co.uk

The network I am wokring on is a bit tricky that it has set up a really restric firwall and webcache (squid).
Will this affect the performance of smokeping? I dont think it will at the begining. however, the packet

well, from what you write I can't really figure out where your problem
is. If you encounter 100% packet loss then either the node is dead or
you are blocked by a firewall. Do you know where the firewalls are and
what their policy is?

Generating static pages?

Hi all :)
I'm trying smokeping for the first time, to monitor the latency to some
interesting hosts from a big website.

At this moment I'm using the .cgi to show the graphs on the web, but I'd
prefer to follow a potentially more secure approach generating static pages
and putting them in a directory readable from the webserver.

I've seen this param in the configuration help:
"pagedir	Directory to store static representations of pages."
but noting happens, even changing "pagedir" to a valid dir.

I'm trying to figure out how to tell smokeping to save static .html pages in
a dir. 
Any tips? Please, no RTFM :DD

Graphics not displaying

Greetings - 

Slight problem here.  When I go to the smokeping.cgi main page, I see the
targets listed in the left-side column, and the footer information down in
the lower left hand corner.  I also see the image outlines of where the
images should be, but no graphics.  When I click on the page where the
graphic should be I link to the second page where the extended views (3
hrs, 30hrs, 10days, etc) are shown but there are not any graphics there
either.

If I pull up the graph directly -
file:///usr/local/apache2/htdocs/smoke/Cisco1_RTR_2600_mini.png - the
graphic displays with no problem.

When I try to access the same file via smokeping.cgi, I get the following
results:

The requested URL /usr/local/apache2/htdocs/smoke/Cisco1_RTR_2600_mini.png
was not found on this server.

Please help me.

This is an extract from my smokeping.cgi file:

#!/usr/bin/speedy -w

# -*-perl-*-

use lib qw(/usr/local/rrdtool/lib/perl);

FW: Graphics Not Displaying

Greetings - 

Thanks for the quick response however I do not believe that the answer is
so obvious.

If I pull up the graphic directly from the directory with a web browser
file:///usr/local/apache2/htdocs/smoke/Cisco1_RTR_2600_mini.png

the graphic displays with no problem.

Only when I try and view and the graphics via smokeping.cgi do I get the
error telling me that the file is not found.

The requested URL /usr/local/apache2/htdocs/smoke/Cisco1_RTR_2600_mini.png

was not found on this server.

BUT IT IS THE SAME DIRECTORY!

So the images are there, I can see them when I grab them manually but not
through smokeping.cgi.

/etc/config

owner    = TEVA USA

contact  = sgingola <at> tevausa.com

#mailhost = smtp.mailhost.abc

Right, because your web browser is running on the same system as your 
webserver.  What happens if you replace the "file://" part of your 
above URI with "http://"?  Bet you'd get a 'file not found'.

Because when you are using the "file://" URI method, the "root" of the 
path is "/", but when you use "http://", the "root" of the path is

Re: FW: Graphics Not Displaying

Ah.  Thank you, you Unix guys.

My NIX training is still in its infancy and I admit that I did not
understand that there was a difference between URI and URL.  Actually, I
had never even heard of URI before tonight.

That worked perfectly.  Thank you for all your help.

Echoping through proxy

Hello there:

I notice that the echoping can send echo packets through a proxy to the testing domain. For example:

% echoping -h http://www.google.com mycache.aname.com:80

where mycache.aname.com:80 is the proxy that the echo packets need to go throgh. anyway, does the
smokeping echoping prob does this as well? 

nice day

Suzy
