Hi There.
I have been thinking about using Ganglia to monitor a broader range of
networked devices for a while. Many of these systems do not run common OS
platforms and communicate via the SNMP protocol. Last year I came up with a
Ganglia 2.5.x hack that enabled a host to send gmetric updates
I've been checking out the recent 2.6.0 snapshot and it's looking good.
Matt, it looks like you have made provisions for some kind of host proxy
mechanism. Is it functional
to the point where I can send gmetric messages on behalf of others?
If you recall, I produced a similar hack for an earlier

Hi.
No trouble with building/installing on Solaris this time. I've started looking
at gmond and getting familiar with the new configuration format. Can you please
provide examples of how to use 'allow_ip' and 'allow_mask' to restrict what
hosts can send data and request data from gmond?

Does this work for you on Solaris?

For some time now I've wanted to implement some kind of mechanism that would
allow me to transmit metric information by proxy - that is send data from one
host on behalf of another. The reason for this is that I would like to monitor
'black box' network devices that can only be accessed via SNMP
OK,
Ignore that. Just realized that I have to run 'bootstrap'.

Thanks Matt. I'm compiling right now so expect some feedback soon.
By the way, I have one *tiny* request for 2.5.8 and it is solaris related.
For some time now I believe the network related metrics (bytes_in , bytes_out)
have been absent from the 2.5.x solaris releases. Someone added thes

Hi Matt.
Just notice that you have a new version of 2.6.0 on your web site dated Aug.

Matt,
I got hold of your latest ganglia-apr-2.6.0.tar.gz . Looks like you've modified

Does this test pave the way for a new version of 2.6.0 with unicasts working

Matt,
I included my modified mcast.c in this message since it's pretty small. I
started off by adding includes but then I realized I was mislead and commented
out my additions. The real change is near line 58 where I moved the

What's next? Bring on 2.6.0

still there. (Solaris 5.8 and 5.9)

Hi.
I'm having an interesting time with the Ganglia webfrontend and PHP safe mode.
I'll start off by saying that safe_mode works just fine on my MacOS X webserver
( Apache 1.3.29 with PHP 4.3.6 ). I set safe_mode_exec_dir to point to the
directory containing the "rrdtool" executable and it all
ep things consistent!

Hi.
I am unable to build Ganglia 2.6.0 on Linux or Solaris. The libhttpd directory
is missing from the ganglia-2.6.0.tar.gz I downloaded today. I checked an
earlier version of 2.6.0 I built a while ago and it is there.

I guess this message is directed to Matt Massie since he appears to be the
driving force behind the new 2.6.0 features. I've been reading through Matt's
previous emails describing the features in 2.6.0 and I'm pleased.
The most important change for me is the ability to specify unicast channels.
Hi.
I'm trying to understand how the webfrontend determines if a ganglia host is up
or down.
The host_alive function in ganglia.php contains the following condition:

Now, I think that TN is the difference between the current time and the
