[Devmon] Initial weather map implementation

[Buchan M. <bg...@st...>]

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 ...

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,

How so? On mouse over it should show the CPU graph. On clicking it takes you 
to the trends page.

I only get one graph on mouse over (as I had intended).

I'll try and get either decent screenshots, or a demo up somewhere ...

The next step is to make it easier to generate parts of the config (or, an 
editor), possibly using some CDP data (I have a cdp test which I am working 
on).

That's the code I started with on Wednesday morning. Yesterday morning I 
merged in some of the changes Howie made (available here: 
http://wotsit.thingy.com/haj/cacti-weathermap.html).

I will look at adding some of the options, but it won't be possible to have 
100% compatibility (in the config). It may actually be possible to add 
features not available in the cacti plugin.

The features I still need are:
1)Better arrow placement (VIA keyword in the network-weathermap.com one)
2)Icon support

> Don't know if they would make it harder to port or not.

I suspect support for the VIA keyword is about 10 minutes of work, and Icon 
support about 20 minutes ... let's see. Support for some of the DEFAULT 
settings might take bit longer.

I was right mostly ... except that trying to get transparency right for both 
cases (png file for icon has transparency or not) and trying to get the label 
and the icon to both display nicely took more time.

With this version, put your images in /etc/hobbit/images (or, specifically, 
the ICON tags should have a path relative to /etc/hobbit).

Hi Buchan,

This is great, I have it up and working but only if I run the script
manually, It won't run from hobbitlaunch.
I took your entries from weathermap.cfg and added to hobbitlaunch.cfg as
below but the hobbit environment variables don't seem to be passed to
the perl script so it fails to run.

[weathermap]
        ENVFILE /home/hobbit/server/etc/hobbitserver.cfg
        CMD $BBHOME/ext/weathermap.pl --image-uri=weathermap.png
        LOGFILE $BBSERVERLOGS/bb-weathermap-wan.log
        INTERVAL 1m

I then reread the install notes and noticed the following that I had
over looked the following, I assume this is why the environment
variables are not getting passed.

the weathermap.cfg file to a directory referenced by hobbitlaunch.cfg
(e.g. $BBHOME/etc/hobbitlaunch.d/) 

Can you expand on the weathermap.cfg and hobbitlaunch.cfg configuration.

Thanks

Craig

By manually, do you mean in a shell that was started by bbcmd (or some other 
means that ensures the ENV variables are available)?

Hmm, that's almost impossible ... everything run by hobbitlaunch should get 
the environment variables.

Is this the right file?

echo "directory $BBHOME/etc/hobbitlaunch.d/" >> $BBHOME/etc/hobbitlaunch.cfg

But, it's effectively the same as cat'ing the file on to hobbitlaunch.cfg 
(but, using it makes it easier to ship extensions in packages, which is what I 
plan to do once I'm finished with major changes to this).

I can't think of anything else that would be wrong, but I'll think about it 
some more.

[Craig B. <cra...@ro...>]

Hi Buchan,

I'm looking at creating a weathermap of our data centre and want to
include information from our devmon polled temperature / humidity
sensors.

Is it possible to include another option or change the existing option
so that you can specify the devmon test name and alias and retrieve a
single value.

Something along the lines of the following syntax and conf entries 

"TARGET $devmontest $devmonalias"

NODE APC-EMS1
        LABEL APC-EMS1
        POSITION 200 200
	  TARGET env temperature


Thanks

Craig

It really depends what you want the behaviour to be.

I don't know if I want to write parsers for each devmon test ... but it would 
be relatively easy to allow different tests for the label colour (currently 
the colour of the 'cpu' test for the device), and which graph to show on 
mouse-over on the device (currently 'cpu', but anything that goes into a 
single string in the service= paramater to hobbitgraph.sh could work).

Is this what you were thinking?

Regards,
Buchan

Re: [Devmon] Weather Map feature request

[Craig B. <cra...@ro...>]

Hi Buchan,

That would work for the graphing side, But I would also want to have the
value pulled from Devmon displayed on the weathermap next to the label
if possible.

Thanks

Craig
