Re: [Ganglia-general] Disk metrics

Linux (32 and 64bit). There is no hurry though, I have collectd installed on machines locally and it provides io graphs by default. I am just curious because this is one of basic things about a computer system and I find it weird that ganglia does not have it included in official distribution

[Ganglia-general] Node gmond does not reconnect if gmond at head node is restarted

Hi all! Is it a known bug that if gmond on head node is restarted, then other nodes do not reconnect and stop sending data until their gmonds are also restarted? This happens by using unicast udp channel, I didn't try multicast. Thanks, b.

According to the code it only omits lo* and bond* interfaces but sums data of all other interfaces and returns it as metric. I think you are the victim of large counters on 32bit OS. Does gmond collect interface data correctly if you bring it down and up again which resets it's counters? If that

It goes like this: - Ganglia agents (gmond) push data (over UDP) to designated cluster headnodes (same gmond daemon, only configured to accept UDP data). - the most recent data is accumulated in memory on these headnodes - gmetad must be configured to periodically pull data from one (or more) of
