Re: [Ganglia-developers] Ganglia server is running under high server load and high Disk IO

How many total metrics are you keeping track of ? Also what Ganglia

I have to restart the gmetad service, then it start showing the web page again. It shows iowait time over 40 all the time and server load around 3. I am graphing around 130-150 servers. It contains around 50 hadoop nodes. I am not using any RRDcache or memcached on my server. Please suggest me if there are any ganglia optimization tips or documentation available.
