A simple package that logs executions time of code chunks in a format that makes it easy to create AWS metrics
This simple package is supposed to provide timing for methods in your code, and allow an easy creation of custom metrics in AWS CloudWatch
npm install cloudwatch-perf-log
const performanceTimer = require("cloudwatch-perf-log");
performanceTimer.start_timing("some-code-block");
...
performanceTimer.stop_timing("some-code-block");
Will provide logs in the output of e.g. lambda logs, that looks something like thos:
performance-test ms 10
That log as viewed in CloudWatch logs will look something like
2017-03-22T11:27:32.888Z 8aa3e28a-0ef2-11e7-bdf8-69bab79b207d performance-test ms 2
Given that formt it is trivial to create desired custom CloudWatch metrics using the console: using the following template [timestamp, request, metric=performance*, unit=ms, value=*]
and specifying $value
as the value of the metric
