|
||||
## Usage
|
||||
|
||||
Use TypeScript for best in class intellisense
|
||||
The `@push.rocks/smartmetrics` package provides an easy way to collect and monitor system metrics such as CPU and memory usage within your Node.js applications. It's built with TypeScript, offering type safety and IntelliSense in editors that support it.
|
||||
|
||||
## Contribution
|
||||
### Getting Started
|
||||
|
||||
We are always happy for code contributions. If you are not the code contributing type that is ok. Still, maintaining Open Source repositories takes considerable time and thought. If you like the quality of what we do and our modules are useful to you we would appreciate a little monthly contribution: You can [contribute one time](https://lossless.link/contribute-onetime) or [contribute monthly](https://lossless.link/contribute). :)
|
||||
Before diving into the code, ensure you have `@push.rocks/smartmetrics` installed in your project and your environment is configured to use ES Modules (ESM) and TypeScript.
|
||||
|
||||
For further information read the linked docs at the top of this readme.
|
||||
#### Initialization
|
||||
|
||||
## Legal
|
||||
> MIT licensed | **©** [Task Venture Capital GmbH](https://task.vc)
|
||||
| By using this npm module you agree to our [privacy policy](https://lossless.gmbH/privacy)
|
||||
To begin using `smartmetrics`, you need to import the module and initialize it:
|
||||
|
||||
```typescript
|
||||
// Import dependencies
|
||||
import { SmartMetrics } from '@push.rocks/smartmetrics';
|
||||
import { Smartlog } from '@push.rocks/smartlog';
|
||||
|
||||
// Setup a logger (or use your existing logger if applicable)
|
||||
const logger = new Smartlog({
|
||||
logContext: 'applicationName',
|
||||
minimumLogLevel: 'info',
|
||||
});
|
||||
|
||||
// Initialize smartmetrics with the prepared logger
|
||||
const smartMetrics = new SmartMetrics(logger, 'sourceName');
|
||||
```
|
||||
|
||||
In this snippet, `Smartlog` is used for logging purposes. Replace `'applicationName'` and `'sourceName'` with appropriate values for your application.
|
||||
|
||||
#### Starting Metrics Monitoring
|
||||
|
||||
With `smartMetrics` initialized, you can start the metrics monitoring process:
|
||||
|
||||
```typescript
|
||||
smartMetrics.start();
|
||||
```
|
||||
|
||||
This starts the collection and monitoring of various system metrics. By default, `smartMetrics` sends heartbeat messages including these metrics at a regular interval.
|
||||
|
||||
#### Metrics Collection
|
||||
|
||||
To manually collect metrics at any point, you can call the `getMetrics` method. This could be useful for logging or sending metrics to a monitoring tool:
|
||||
|
||||
```typescript
|
||||
async function logMetrics() {
|
||||
const metrics = await smartMetrics.getMetrics();
|
||||
console.log(metrics);
|
||||
}
|
||||
|
||||
logMetrics();
|
||||
```
|
||||
|
||||
#### Customizing Monitoring
|
||||
|
||||
The `start` method begins an unattended process of collecting and logging metrics. If you require more control over how and when metrics are collected or reported, you can use the `getMetrics` method in combination with your logic.
|
||||
|
||||
#### Stopping Metrics Monitoring
|
||||
|
||||
To stop the automatic metrics monitoring, simply call:
|
||||
|
||||
```typescript
|
||||
smartMetrics.stop();
|
||||
```
|
||||
|
||||
This stops the internal loop that periodically collects and logs metrics. It's useful for clean shutdowns of your application or when metrics monitoring is only needed during specific intervals.
|
||||
|
||||
### Understanding the Metrics
|
||||
|
||||
The `getMetrics` method returns a snapshot of various system metrics, including CPU and memory usage. Here's a brief overview of the information provided:
|
||||
|
||||
- `process_cpu_seconds_total`: Total CPU time spent by the process.
|
||||
- `nodejs_active_handles_total`: Number of active handles.
|
||||
- `nodejs_active_requests_total`: Number of active requests.
|
||||
- `nodejs_heap_size_total_bytes`: Total size of the heap.
|
||||
- `cpuPercentage`: Overall CPU usage percentage.
|
||||
- `cpuUsageText`: Readable string representation of CPU usage.
|
||||
- `memoryPercentage`: Percentage of memory used.
|
||||
- `memoryUsageBytes`: Total memory used in bytes.
|
||||
- `memoryUsageText`: Readable string representation of memory usage.
|
||||
|
||||
### Conclusion
|
||||
|
||||
`@push.rocks/smartmetrics` offers a straightforward and efficient way to monitor essential system metrics of your Node.js application. By integrating it, you gain valuable insights into the performance and health of your system, aiding in diagnosis and optimization efforts.
