Server Endpoint Latency & Runtime Intelligence.
Monitor.JS profiles backend route execution duration down to the nanosecond. It automatically diagnoses whether an endpoint is Optimal (Fast), Lagging (Needs Indexing), or Degraded (Bottleneck), isolating slow database operations before users experience latency.
// server.ts (Express.js Backend)
import express from "express";
import { monitorJs } from "@wispro/monitorjs";
const app = express();
// Initialize Monitor.JS Runtime Latency Profiler
app.use(
monitorJs({
apiKey: process.env.MONITORJS_API_KEY,
serviceName: "core-banking-gateway",
slowThresholdMs: 300, // Flag endpoints exceeding 300ms
onDegradedEndpoint: (metric) => {
console.warn(
`[Monitor.JS Alert] ${metric.method} ${metric.path} ran in ${metric.durationMs}ms - Grade: ${metric.grade}`
);
},
})
);
app.post("/api/v1/checkout", async (req, res) => {
// Monitor.JS automatically calculates precise execution time,
// database query overhead, and assigns an algorithmic health grade
const data = await processOrder(req.body);
res.json({ success: true, data });
});
app.listen(8080);Granular Latency & Bottleneck Isolation
Nanosecond Precision Timers
Leverages `process.hrtime.bigint()` to track microsecond execution times without rounding errors or clock drift inaccuracies.
Automated Health Grading
Every request receives an automated score (A+ Optimal, B Warning, Critical Degraded) based on route complexity and SLA targets.
Database & ORM Waterfall
Identifies whether slow endpoints are caused by N+1 SQL queries, unindexed table scans, or external API third-party webhooks.
