Hey Dan, Sounds like i do need to check some things then.
The load balancer does a health check every 30 seconds. Going through the monitor logs, the cpu was peaking up to about 60% which im not too sure if was caused by load or by the riak process doing whatever it was doing. And, I do seem to be running pretty high on memory so ill see if i can lower that by configuring the buffer size on the innostore backend. If i see it happening again, ill try and gather more information. gs On 18 June 2010 14:15, Dan Reverri <[email protected]> wrote: > Hi Gareth, > > I'm not aware of any mechanism that turns the stats url off for any reason. > How often are you pinging the stats url?
