If you are getting connection refused when connecting to localhost:8649
it
means that
1. you have no tcp_accept_channels specified on the host
2. you have a setting of deaf = yes
3. Your gmond is not running. Please verify that gmond is running. If
not
try starting it up with gmond -d 5 and see if it gives you a hint why
it's
not starting up

[Ganglia-general] Do Ganglia python modules run with root privileges?
Hi, I've written some python modules that need to read some directories under the /proc filesystem that are read-only by root. I found on the Ganglia wiki mention of the python modules running as root even if the gmond runs as a non-root user ... * all metric collection routines run as root even if the process has since lowered privileges, be careful with your python module scripts http://sourceforge.net/apps/trac/ganglia/wiki/ganglia_release_notes However, my testing seems to indicate that this is no longer true. ie. the python modules don't run as root, but with the permissions of the setuid user defined in gmond.conf. Does anyone know if this has changed since the wiki was written or if it's just that I'm doing it wrong? Thanks, Nick -- Special Offer -- Download ArcSight Logger for FREE!

Re: [Ganglia-general] Problem displaying Virtual Machine data with hsflowd and ganglia 3.2.0 in an Openstack Compute node.
Hi Neil, thanks a lot for the help! I verified libvirt version, it's 0.8.8 I've dowloaded and compiled hsflowd revision 227: now ganglia correctly receives and processes statistics VM Bytes Written and VM Writes. (http://imageshack.us/f/846/vmstats.png/) Other disk statistics for VM ( VM Bytes Read, VM Disk Errors, Free Vdisk Space, VM Reads, Total Vdisk Space) are not displayed, and hsflowd -dd displays errors similar to the following: libvir: QEMU error : invalid argument in invalid path vda not assigned to domain virDomainGetBlockInfo(vda) failed I've logged a few minutes of hsflowd activity, if it can help you you can download it here: http://www.mediafire.com/?g4jac7dm3mmb662 2011/8/29 Neil Mckee neil.mckee...@gmail.com Sorry, the failure of virStorageLookupByPath() was preventing virDomainBlockStats() from being attempted. I checked in a fix for this, and also code to try the newer virDomainGetBlockInfo() call as a fallback should virStorageLookupByPath() fail. This call only came in with libvirt version 0.8.1. Are you running something newer than that? (see /usr/include/libvirt/libvirt.h) If this works, we should make a new release of hsflowd, so please let me know how it goes.

Do I need to tell hsflowd explicitly to use target=vda call? If yes, how? Thanks in advance, Emanuele 2011/8/25 Emanuele Verga verga.emanu...@gmail.com Hi Neil, Yes that's possible, the problem is Nova places each image in a separate folder (/var/lib/nova/instance/INSTANCENAME/), so we would have to create a new pool with the corresponding path each time a new instance is created, and if we start to add more servers it quicly becomes impractical. I've not yet been able to try the hsflowd version you suggested, I'll test it tomorrow and let you know. Thanks for the help! Emanuele -- Special Offer -- Download ArcSight Logger for FREE!

[Ganglia-general] [gweb] drop-down for metrics?
Hi all, I've been watching the development of the new Ganglia Web interface, and we really like it. The main complaint at this point is the lack of a drop-down for the metrics. People don't have them memorized and without some hint, they don't know what they can look at. Is there a way to get the drop-down list of metrics back in the new design?

Re: [Ganglia-general] Do Ganglia python modules run with root privileges?
Nick, I have a few python modules that read the /proc directory; however, I think the files that they access are readable by non-root users.
