I could accept averages being leveled out in time, but not peaks.
There is no use in keeping statistics at al, if all numbers are going to be inaccurate after some time.
I'm currently trying to make a performance report on a VI3 installation i did for a client, but these statistics are driving me nuts.
Many of the graphs are either not available, or not making any sense.
The total memory usage for the cluster (2 servers with 12GB each) is currently showing 55%. The other statistics are showing 'not available', so i cannot get a real value. Now i know this number is wrong, because i can see that only about 7GB (about 30% of the total 24) is in use.
Now when i look at the Hosts separately, i see one uses 24% and the other 31% of its memory, hence the 55, they just get added up instead of averaged.
And there are many more weird thing going on with the statistics, enough to make me decide the graphs look nice, but apart from that are totally useless.
