Hello, I have ganglia 3.1.2 running on RHEL 32bit.
I have often noticed that the graphs have gaps in them, and am asking for help on how to eliminate these gaps.
If I happen to access the ganglia page while a gap is occuring, it shows that everything is down. After a while everything is back online, but there is no ramp up or down in the graph like there is upon restart or reload of ganglia. It simply has data... blank .. data.
I am monitoring *1630 nodes. *So, I thought that perhaps it was getting overburdened at times from all the traffic. However I am using a very beefy machine, and do not see high cpu or memory usage even during these gaps. Also the network folks don't see any abnormally large traffic on the network.
I have tried to increase the send_metadata_interval and the polling interval , but I still see gaps.
Any ideas? Thanks! -- Cassandra (609) 243-2413 Unix Administrator "From a little spark may burst a mighty flame."-Dante Alighieri
