A simple, bare-bones package for monitoring NodeJS memory usage using the console.
Memory Lite is a simple, bare-bones package for monitoring NodeJS memory usage using the console.
Memory Lite can be installed using the package manager of your choosing. The example command below uses yarn.
$ yarn add memory-monitor
Usage is extremely straightforward -- 1) import the package, and 2) initialized the monitor. Memory Lite can be used without passing any arguments, however all arguments and their defaults are shown below:
// <app-entry-point>.ts
import memoryMonitor from 'memory-lite';
memoryMonitor({
interval: 10000,
rss: true,
heapTotal: true,
heapUsed: false,
external: false,
arrayBuffers: false
});
With this default setup, the following will be output to the console at 10 second intervals (numbers shown are arbitrary):
rss: 21.9 MiB | heapTotal: 4.6 MiB
If all boolean arguments set to true
, the following will be output to the console:
rss: 22.9 MiB | heapTotal: 4.9 MiB | heapUsed: 4.3 MiB | external: 294.7 KiB | arrayBuffers: 43.7 KiB
Name | Default | Description |
---|---|---|
interval | 10000 (ms) | The sampling rate expressed as time between sample (and subsequent logging) events. |
rss | true | Determines whether or not rss should be included in the output. |
heapTotal | true | Determines whether or not heapTotal should be included in the output. |
heapUsed | false | Determines whether or not heapUsed should be included in the output. |
external | false | Determines whether or not external should be included in the output. |
arrayBuffers | false | Determines whether or not arrayBuffers should be included in the output. |
Contribution is welcome, although there is probably little more to be done. Some options include:
These would constitute fairly large changes and may even warrant packages of their own, however they are valid ideas for improving the utility of this package.
