Alert Pattern - why does this not match

Hi,

this is from a SmokeAlert foo cleared e-mail created by smokeping
2.0.9 (from Debian stable):

Pattern
-------
==0%,>0%,*12*,>0%,*12*,>0%,*28*

Data (old --> now)
------------------
loss: 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%,
0%, 0%, 0%, 5%, 0%, 0%, 0%, 0%, 0%, 5%, 0%, 0%, 0%, 0%, 5%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%, 0%
rtt: 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms,
1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms,
1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms, 1ms

The loss data row still has three >0% items, and the trailing *28*
should indicate that smokeping shouldn't care about whether the last
non-zero data point is last or not. But the alert is still raised when
the last data point is non-zero and cleared when the last data point
becomes zero again.

In the mean time, I have modified the pattern to read
==0%,>0%,*12*,>0%,*12*,>0%,*28*,>=0%
and we'll see whether that helps.

What have I been doing wrong, and is my workaround the desired one?

Greetings

Possible to change image type / quality?

Hi all ...

I'm just wondering whether it's possible to change the file type / 
compression that's used to generate the graph images?

My Smokeping setup is growing larger and larger, and the [combined] size 
of the images is starting to become a problem in some of the sections.

Obviously when I'm connecting over the LAN this isn't a problem, but 
whenever I need to use a remote connection I can definitely feel that 
it's a lot slower.  [The server is just running on my home DSL line, so 
it's not a particularly fast connection.]

I really don't want to make the graphs physically smaller [IE - less 
pixels], so I'm actually hoping that I can just change the file type / 
quality and end up with some smaller images that way?

Any ideas?

Regards,
--David

PS - Yes, I've already split the graphs into different sections to 
reduce the number that are displayed on any one page.

Re: Possible to change image type / quality?

Hi David,

rrdtool images are as small as they get with this kind of
technology. What you could do, if you were using rrdtool 1.3, is to
disable all anti-aliasing (fonts and graph) this should cause the
graphs to get quite a bit smaller.

I don't think it will be easy to reduce the image data size a great deal,
here's what happened when I used GIMP to convert from png to gif and jpg:

-rw-r--r--  1 ged ged    46623 2008-10-08 09:36 WWW3-HTTP_last_108000.png
-rw-r--r--  1 ged ged    32625 2008-10-08 09:38 WWW3-HTTP_last_108000.gif
-rw-r--r--  1 ged ged    47200 2008-10-08 09:38 WWW3-HTTP_last_108000.jpg

46k to 32k isn't what I'd call a useful reduction in a case like this,
I'd say you're looking for at least a factor of three to make a sensible
impact on the 'user experience'.

Using gzip only cut the file size by about ten percent, and your browser
and the server should be able to use compression over the link anyway.

You might want to try setting up proxy Web servers at the locations
remote from the Smokeping server, and keeping the images up to date
for example using rsync in the background.  It will be fun, and also

Passing arguments to FPing

Hi,

I've tried to search for a solution to my problem, but so far no success.

I want to be able to ping a destination with different source IPs. The reason is that I want to be able to ping
both inside and outside a VPN tunnel. As I understand it FPing can do this with the -S option. But how do I
utilize this in the smokeping configuration ?
Can I make two probes one for each source IP ?

This is my first post here, so I apologise if I'm missing something.

You should read the documentation.  It's on the Smokeping Website.

The fping binary is part of the set of tools provided by your
operating system, and Smokeping just uses whatever it finds there.
Unfortunately there are several different versions of the fping probe
in existence, and you may have one which does not support setting the
source address.  This is checked in the Smokeping code and it will
inform you of the problem if it exists.  You may want to set the
Smokeping --debugging option (more documentation reading required... :)

Was that gentle enough? :)
