[Ganglia-general] Ganglia truncating larger status messages

2006-02-22 Thread Chris Black

Hello list,

We're using Ganglia at the University of Michigan to monitor cluster  
nodes, and we found an issue with 3.0.2.  When sending status  
messages from gmond to gmetad, messages over ~66600 bytes would be  
truncated and the trailing /GANGLIA tag (among a few others at the  
end) would be missing, and the gmetad host would mark that client as  
missing.


We found the problem to be in version 0.9.5 of the Apache Portable  
Runtime (APR) that shipped with Ganglia 3.0.2.  Upgrading to the  
newest APR (0.9.7) fixed the problem.


We used the following procedure to correct the problem on Mac OS X  
Server 10.4.4 Buid 8G32:


1) untar the ganglia sources
2) cd into the ganglia-3.0.2/srclib directory
3) remove the 'apr' directory
4) download the 0.9.7 sources of apr into this directory  
(ganglia-3.0.2/srclib)

5) untar the apr sources
6) rename the resulting apr-0.9.7 directory to apr (or create a symlink)
7) move up one directory to ganglia-3.0.2
8) build/install as normal

Hopefully this will be of assistance to anyone seeing a similar problem.

Hi Ian,

 beating me with this advice :-)

 Chris - Please assign the bug to me. Not that I know how to fix this
short term, as upgrading the whole of apr might be a challenge. I
could imagine a way to specify a different apr-location with
configure.

Cheers
Martin
