difference Request count vs Request count - server vs Request count - client

MAkimov — Tue, 20 Apr 2021 12:06:50 GMT

Hello

help me understand the difference between metrics:

Request count - builtin:service.requestCount.total
Request count - server - builtin:service.requestCount.server
Request count - client - builtin:service.requestCount.client
Number of calls to other services -builtin:service.keyRequest.nonDbChildCallCount

And why these metrics have different meanings on the Custom chart and Service Details page/Service Flow?

as an experiment to understand the metrics, I took the EasyTravelWebserver service: 8079

I userd service for MZ=production

I selected metrics and displayed them on the chart

I took the value in 11-10 and compared them for different metrics

Request count - builtin:service.requestCount.total
Request count - server - builtin:service.requestCount.server
Request count - client - builtin:service.requestCount.client
Number of calls to other services -builtin:service.keyRequest.nonDbChildCallCount

result

Request count = 2470
Request count - server = 2470
Request count - client = 627
Number of calls to other services = 2120

conclusions:

Request count =Request count - server
Request count - server > Request count - client
Request count > Number of calls to other services

I decided to compare this value with the value on the Detail page

(chose the value on the chart to correspond to a 1 minute interval)

to my surprise, I saw a value of 562 which is not equal to that of the previous

what does it mean ?

I understand what the metric means - Number of calls to other services

its value can be seen in the service flow

I decided to compare this value with the value on custom charts

took the interval from 11-00 to 11-30

Request count - server
Request count - client
Number of calls to other services

result

Request count - server = 92.6K
Request count - client = 21.2K
Number of calls to other services = 81K
ServiFlow Call to caller service = 77.1
ServiFlow Request =77,3

conclusions:

Request count not equal ServiFlow Request
ServiFlow Call to caller service not equal Number of calls to other services

Could you help me understand the difference between metrics

This is the reply I got from Support:

Request count - builtin:service.requestCount.total - Calculates the total # of requests from both the client and server side

Request count - server - builtin:service.requestCount.server - This Metric is exclusively regarding the # of requests from server side

Request count - client - builtin:service.requestCount.client - This Metric is exclusively regarding the # of requests from the client side

Number of calls to other services -builtin:service.keyRequest.nonDbChildCallCount - Assuming that this request will call other downstream services, this will also get you the total count

also forgot to mention for the last metric It refers to Key requests, not regular requests.
