Hi,
I want to report the 99th percentile from one of our BTs in a sla with some external partner.
In the context menu of a normal chart I can change the aggregation to percentile 99, but I have no idea, which column (average, max, min, last...) shows the right value.
When I use the percentile chart, there is no 99th. Just the 95th, 90th, 75th, ....
Which way would show me the right values for my BT?
Regards,
Jan

Hi Reinhard,
thanks for your reply. The first dashboard will do it for me.

PS: In the percentile chart you are able to 'select' some predefined columns like '95th Percentile' in your screenshot. I was wondering, why 99th is not possible. My question pointed on the table and not the graph
EDIT:
I just compared the percentile chart with the "normal" chart. I know the percentiles are calculated for completed hours, so I took a custom time range: 8:00 - 9:00
The values are completely different. I was expecting, that the 95th Percentile on the left would be the same as on the right.
I am a bit confused now. What am I doing wrong?
Regards,
Jan

Jan,
for reporting SLA I could recommend a chart like this one. It combines all the relevant metrics in one chart. Just add the result metric of your BT (assuming response time) mutilpe times to a single chart and then change the aggregation value of the individual to max, min, average as well as the percentiles you want. If there is a big skew between max and min I recommend to change the axis type to logarithmic.
In a percentile chart liek the one below there is of course no 99th percentile to 'select'. The x-axis itself is the percentile and the y-axis is the value of the percentile. So if you go to the right end (99) on the x axis and read the y value there that's your 99th percentile aggregated over the whole timeframe.
