Hello,

I have an Elastic 8.8.1 cluster up and running, and being monitored via Metricbeat feeding into stack monitoring, and I can see a chart of index rate.

I'd like to visualise the 99th percentile index rate across a data stream. Has anyone done this previously and, if so, how would I go about it, please?

Thanks!

Hi.

- Go to Kibana -\> Management -\> Index Patterns and set up an index pattern that matches the data stream's indices.

- Now, go to Kibana -\> Visualize -\> Create Visualization and select the visualization type that best fits your use case. In this scenario, we'll use the "Line" chart

- select data: For the X-axis, choose a suitable time-based field that represents the timestamp of your data, like "@timestamp" or any other field with timestamp information

- metrics aggregation: For the Y-axis, choose the "Percentiles" aggregation from the list. In the "Field" dropdown, select the field that represents the index rate (e.g., number of documents indexed per second).

- Configure Percentile Aggregation: After selecting the "Percentiles" aggregation, you will see a "Percentile Ranks" input box. Enter `99` here to calculate the 99th percentile index rate.

- apply filter and save visualization
