Re: [Devmon] Initial weather map implementation

[Engineering <fo...@tr...>]

I got it to load and it seems to function pretty good.  I noticed that the
node seems to link back to the trends column and when you are doing
mouseovers it is an issue.  Because there are so many graphs on the page it
is unable to bring up a mouseover image.  I do however like how easy it was
to get the node and links done with overlibs.  Normally it takes about 15-20
lines and this time it only took about 3-4.  I didn't have to go hunting for
the links for the overlib and the links for when you click on the overlib.
	So far I think it a good step in the right direction.  I noticed the
code you used was from http://netmon.grnet.gr/weathermap/ which hasn't been
updated since February 20th, 2006.  Didn't know if you were aware of one
that is currently being kept up-to-date at
http://www.network-weathermap.com/.  I know that the first one is perl and
the second one is done in php but the php version seems to have more
options.  Don't know if they would make it harder to port or not.

Thanks,

-Josh

Subject: [Devmon] Initial weather map implementation

I have been hacking on the perl versions of weathermap that I found, and
have 
hacked one up that works with Hobbit and devmon (for now, only devices using

the if_load test).

The interface load and descriptions are taken from the if_load test
(retrieve 
from Hobbit via hobbitdlog), and the map is created using a configuration
file 
(mostly the same format as that used by the other implementations).

The difference is that a lot less information needs to be included in the 
weathermap configuration (the INFOURL, OVERLIBGRAPH, TARGET, BANDWIDTH), as 
they are unnecessary for Devmon/Hobbit.

However, the node names need to match the hostname used in bb-hosts, and the

interfaces need to be specified with the INTERFACES tag.

E.g., this is sufficient to get two nodes and a link between them, with
popup 
graphs of the interface (on the arrows) and load (on the nodes). 

NODE tau
        LABEL TAU
        POSITION 86 524

NODE upsilon
        LABEL UPSILON
        POSITION 421 524

LINK tau-upsilon
        NODES tau upsilon
        INTERFACES Gi1/1 Gi1/1


A tarball is available at: http://staff.telkomsa.net/~bgmilne/devmon-
weathermap-1.1.2.tar.gz for now.

I think sufficient instructions are available, but I would love to hear what

other people think ...

Regards,
Buchan
