Re: [Ganglia-general] Ganglia - gmetric --slope=positive
Hi Ayman, Unfortunately that is not gonna work. The slope=positive works well if your polling period is similar to gmetad polling period. Gmetad polls for metrics every 15 seconds and since you are sending new counter values evey 5 minutes for 4 minutes and 45 seconds the counter value gmetad is polling stays the same. You may be better off calculating differentials yourself.

[Ganglia-general] Show one cluster in two groups
Hi, How can I make ganglia show one cluster in two groups? I have a ganglia server running gmetad and gmond receiving information from two machines collecting gmon information from two clusters. These two machines are running gmond only. All of two cluster nodes are running gmond only and are sending gmond info to these two machines. Everything is running fine. Now I would like to split the second cluster into two groups. I tried to configure the first group nodes send gmon info in one port(channel) and the second group nodes send in from another port. But I could not make it work. Anyone have the settings in a similar way? Thank you! Paul -- Dive into the World of Parallel Programming.

Re: [Ganglia-general] segfault on gmetad making Ganglia unusable.
I can't help unfortunately, but I can say that I've been having exactly the same issue, although less frequent (crashes anything from several times a day to once every couple of days). What is your gmetad hosted on? Mine is on Amazon Debian EC2s.

Re: [Ganglia-general] Show one cluster in two groups
Ok. The Tree being-- GRID - CLUSTERS- NODES , what you expect to see in the Choose a source drop down menu with the above Gmetad configuration ? Because you cant split a cluster in to multiple node groups visually AFAIK. thanks, Jay The one who possesses knowledge becomes immortal On Sun, Feb 8, 2015 at 3:51 PM, Paul p...@space.mit.edu wrote: Hi Jay, Thank you so much for quick response.
