We are trying to get data of request attribute which is created for Loadrunner request tagging. So we need load runner tagged request attribute data as a metric to retrieve Avg and 90% response times. We have created a metric with Avg as aggregation but not 90 percentile. is there a way to get that 90 percentile data other than Multi dimensional analysis? Also, is there any better way to copy chart table data to excel?
You don't need to create custom metric. You can use Data explorer to create output for Response time 90th percentil filtered by your request attribute (and/or split by service) and use Table format to visualize preview. If you need then switch to Data tab, you can see metric definition that you can use to export data points via environment api v2 (in json format).
