Re: [Ganglia-general] Help! I have a petabyte/s network (Martin Knoblauch)

Hi David and Martin, I suppose the network code is still the code I wrote, so there are two problems I know of: 1. yes there is a problem with owerflows 2. the shown network traffic is the sum of all network interfaces including local loopback devices (lo0...). Both Problems could lead to

[Ganglia-general] Not getting something

I'm trying to set up what I hope/think is a pretty straight forward configuration -- I'm looking to monitor Oracle RAC via ganglia, and I've got three clusters (Prod, Dev and Test). I've got a machine I'm using right now for both gmetad and the web front end piece, and I can only get one host

Re: [Ganglia-general] Not getting something

Andreas, thank you for taking the blame but you are off the hook here. ;-) If I understood David correctly, he is using my AIX Ganglia RPM packages with POWER5 extensions. Here most if not all implementation of how the metrics are collected under AIX have been changed. Everything is

[Ganglia-general] Changing IP addresses sometimes causes heartbeat to not be seen even though TN is an acceptable value.

Hi, I have changed the ip address of some members of one of our cluster and have seen that in some cases this causes the heartbeat to not be recognized even though TN is an acceptable value and current data is still displayed. What happens is that a This host is down' message is displayed and the
