This package provides a simple way to send metrics to a Grafana Cloud Graphite server. It includes support for counters and interval metrics.
https://grafana.com/docs/grafana-cloud/monitor-infrastructure/metrics/metrics-graphite/http-api/
To install this package, use npm:
npm i grafana-cloud-graphite
-
Grafana Cloud: Get free account
-
Grafana Access Token(metrics:write): https://grafana.com/orgs/YOUR_ORGS/access-policies
-
Grafana Graphite UserId: https://grafana.com/orgs/YOUR_ORGS
To use this package, first import the GraphiteMetrics class:
import { GraphiteMetrics } from "grafana-cloud-graphite";
Then, create a new instance of the class with your Graphite server options:
const Metrics = new GraphiteMetrics({
userId: "5435231", // Grafana Graphite UserId
token: "glc_kyupkp...", // Grafana Access Token
ingestEndpointURL: "https://something.grafana.net/graphite/metrics",
namespace: "e2e",
});
// Handle/Listen Metrics error
Metrics.on("error", (err) => {
console.error(err);
});
You can then register counters and interval metrics with the registerCounter
method:
// Register a counter metric with 60.000ms (1 minute) reporting interval
const dbCounterAll = Metrics.registerCounter("db.query.all", 60000);
const dbCounterError = Metrics.registerCounter("db.query.error", 60000);
Use counter example:
try {
dbCounterAll.inc();
await db.query("SELECT * FROM users");
// do some DB query
} catch (error) {
dbCounterError.inc();
// some error handling
}
To stop reporting metrics / clearIntervals, call the stop method:
Metrics.stop();
// Register a counter metric with 60.000ms (1 minute) reporting interval
const dbQueryTime = Metrics.registerStats("db.query.time", 60000);
dbCounterTime.add(100);
dbCounterTime.add(100);
dbCounterTime.add(200);
/* Result:
db.query.time.min: 100,
db.query.time.max: 200,
db.query.time.avg: 133
db.query.time.median: 100
*/
const gauge = Metrics.registerGauge("any.gauge", 60000);
gauge.inc(100);
gauge.dec(50);
// Result any.gauge: 50
