Howdy ! I am a newbie and have some questions about concepts and their mapping to config identifier:
1. In gmetad.conf one can define a "gridname". What is the concept behind this and what does this actually do ? 2. In gmond.conf one can define a "name" for a cluster. What is the concept behind this and what does this actually do ? What is the difference between a Ganglia grid and a Ganglia cluster ? I wanted to create a cluster (grid ?) consisting of two sub-cluster (cluster ?). I have tried the following two configuration without seeing a difference. So what is the difference ? Also, I have noticed that the identifier in gmetad.conf after data_source is completely independent from the actual naming of the cluster. The cluster name then is the one that is presented in the GUI and also reflected in the RRD DB. What is the id in the data_source clause for ? I have noticed that the number of deteced CPUs is inconsistent. It seems to depend on the order in which I start the gmond's / gmetad's. Is there a order and if so which one is the correct order ? ----------------- Configuration I ----------------- MASTER NODE ----------- gmetad.conf gridname "CARLSBAD" data_source "OSCAR 1" cluster_head01 # running gmetad data_source "OSCAR 2" cluster_head02 # runing gmetad cluster_head01 -------------- gmetad.conf: data_source "Rack 1" 11.0.0.5 11.0.0.4 gmond.conf: cluster_head01 cluster_head02 -------------- gmetad.conf: data_source "Rack 1" 11.0.0.5 11.0.0.4 gmond.conf: cluster_head01 ---------------- Configuration II ---------------- MASTER NODE ----------- gmetad.conf gridname "CARLSBAD" data_source "OSCAR 1" cluster_head01 # running gmetad data_source "OSCAR 2" cluster_head02 # runing gmetad cluster_head01 -------------- gmetad.conf: gridname "OSCAR 1" data_source "Rack 1" 11.0.0.5 11.0.0.4 gmond.conf: cluster_head01 cluster_head02 -------------- gmetad.conf: gridname "OSCAR 2" data_source "Rack 1" 11.0.0.5 11.0.0.4 gmond.conf: cluster_head01 ------------------------------------ Your answers are greatly appreciated. Thanx, Matthias
