Symptoms
Analytics, when configured with vertical outlier elimination, shows incorrect data. A 0% elimination displays all peaks and valleys. The total number of operations will be displayed. The problem is that when an outlier is specified, the total number of operations displayed will increase instead of descrease.
There should always be more operations when the elimination is set to 0 rather than when it is set to 1% or 5%
Problem has been noticed on the following analytics:
-> Protocol: NFSv4 operations per second broken down by latency
-> Protocol: SMB operations per second broken down by latency
In BUI, the following outputs have been observed for the analytics "NFSv4 operations per second broken down by latency".It can be seen that using 0% elimination, there are less iops. More precise information is provided when using 1% or 5% elimination.
