[Ganglia-general] Huge metrics' size being reported to gmetad
Hi, I have a grid configuration, with several clusters. I am also using RAM disk for I/O optimization (4GB). I've been noticing that sometimes, gmetad breaks, complaining about lack of space in this tmpfs partition. I checked and I saw that for some reason, some clusters, have hosts which occupy 3MB, 6MB and even sometimes 150MB All together makes the cluster occupy 2GB and consequently occupy half of the ramdisk space. We would normally expect these host metrics to have +/- 336k right? Has anyone experienced this?

[Ganglia-general] latency vs response probability in Unicast
Hi, I have a technical question which concerns my current Ganglia deployment. Basically I have a unicast setup with multiple clusters and one server (no intermediate receiving gmonds), which means: Gmetad runs on Server A and this server also has gmond_cluster1.conf and gmond_cluster2.conf; Cluster 1 has X nodes, reporting back to gmond_cluster1 on Server A; Cluster 2 has Y nodes, in VERY remote location (higher ping), reporting back to gmond_cluster2 on Server A. My questions are: - Since these are UDP connections, and baring in mind that Gmetad is polling the data every 15 sec(default), what's the probability of loosing packets? - Do the packets contain history information? Meaning: if I loose one packet from machine1, does the next packet contain the monitored information about the previous status of the machine? - If the packets contain all the node information history, how does the packet size influence the time of flight and the probability of getting well received at Gmetad? - Does changing the polling frequency (from 15 sec to higher of smaller value) influence the number of well received packages? - How about the transfer volume? How can I check the packets size? Sorry for the long list of questions, but I'm evaluating different Ganglia setups and this matters. Thanks in advance.

Re: [Ganglia-general] multicast not working
Hi Khrist, well that makes sense indeed. All my VM's are running in a private cloud infrastructure so I have no control over their network characteristics. But still, for instance, in gmetad I am gathering the data from node1, and node1's IP is in the same subnet as node2: - node1 IP= x.x.x.169 - node2 IP= x.x.x.96 but in Ganglia frontend, I only get information from node1!! Nevertheless, do I have to do any extra configuration to put multicast working? Because I did nothing in the gmonds. I just installed ganglia and ganglia-gmond and I left gmond.conf as default.

You should doublecheck the name resolution on both gmetad systems in both directions.
