[Ganglia-general] Insane negative values for cpu_idle and cpu_wio when node is CPU bound

2013-10-02 Thread Khrist Hansen
Environment: AIX 6.1 TL7 SP7 gmond 3.6.0 (from http://www.perzl.org/ganglia/) I noticed that a particular node would send insanely high negative values for cpu_idle and cpu_wait metrics when cpu_user + cpu_system were near 100%, i.e. the node is completely CPU bound. The result is major

Here is another example from gstat: CPUs (Procs/Total) [ 1, 5, 15min] [ User, Nice, System, Idle, Wio] 8 (8/ 122) [ 4.59, 2.04, 1.35] [ 99.8, 0.0, 0.2,-67062349824.0,-67062349824.0] OFF Looking at the source code for AIX metrics

[Ganglia-general] mechanism for measuring RTT ( round trip time )

2013-10-02 Thread Ravindra Vyas
good morning to all, I have three basic question regarding ganglia. 1) I have created new custom metric , does it possible to change collect_every time in module.conf file after gmond start? 2) Is there any mechanism for measuring RTT ( round trip time ) between two gmetad or
