Hi,
We have a thousand servers collected on our first collectd server node
The interval is set at 60 on every server
Our load average is about 3, with a lot off wait-io.
The raid 10 volume is composed by 8 drives at 15 000 tour per minutes,
the raid card has got 512Mb cache which is enable in write-back mode
Our current rrdfile settings :
CacheFlush 200
CacheTimeout 120
Before we had this
CacheFlush 120
WritesPerSecond 100
I've seen no change in our load average/io-wait.
Have-you got any idea for reducing my io-wait ?
Best regards,
Benjamin
