How to write a metric expression for adding response time for 2 service entity's in single expression.

banildt · ‎18 Nov 2024

I have to write a metric expression for adding response time for 2 service entity's in single metric expression for SLO creation.

I am good with Entity Selector, but coming to Metric expression for calculating the percentage i have doubt

Entity Selector :

type("service"),entityId("SERVICE-1","SERVICE-2"),mzName("XXXXX")

below is I used for metric expression,

((builtin:service.response.time:avg:partition("latency",value("good",lt(7000000))):splitBy():count:default(0))/(builtin:service.response.time:avg:splitBy():count)*(100))

I have a doubt, I think it may be averaging the response time for the service 1 and service 2 instead of adding them

Please help me on proper metric expression for this requirement

Hi @banildt

It depends on how you should present the insights and then you can configure the metric and entity selector to achieve the target visualization or alerting.

Assess how the data should be calculated and shown and it will be easy to figure out the proper way of proceeding

You can also refer to the attached docs for review:
