API Monitoring and Logging
See every request and response in real time. Catch failing endpoints before your users notice.
>_ the problem
>_ why traditional tools fall short
- $Uptime monitors tell you an endpoint is down but give you zero context about why it failed or what the request looked like.
- $APM tools focus on traces and spans, adding instrumentation complexity when all you need is to see the actual request and response data.
- $Self-hosted log stacks like ELK require dedicated infrastructure, ongoing maintenance, and significant expertise to keep running.
- $Cloud provider logging (CloudWatch, Stackdriver) is scattered across services and regions with no unified real-time view.
>_ how logmonitor solves this
Live Console
Stream API logs in real time. Watch requests flow through your endpoints live, filter by status code or endpoint path, and spot errors the instant they occur.
Zero Clutter
Structured, searchable logs with custom metadata. Tag each log with the endpoint, method, status code, and response time so you can filter and find issues in seconds.
HTTP API Integration
Use the LogMonitor HTTP API to send logs from any language or framework. No SDK lock-in. Send a POST request with your log data and it appears in your console immediately.
Zero Overhead
The async, batched SDK adds no measurable latency to your API responses. Log every request without impacting your p99 response times.
>_ quick setup
import { logmonitor } from 'logmonitor-js';logmonitor.init({ apiKey: 'your-api-key' });// The SDK auto-patches console.log/info/warn/error/debug// Logs are only sent in production (process.env.NODE_ENV === 'production')console.log('App started', { version: '1.0.0' });>_ pricing for this use case
For APIs handling moderate traffic, the Pro plan at $19/mo with 1 million logs per month and 30-day retention is ideal. High-traffic APIs should consider the Scale plan at $99/mo for 5 million logs and 90-day retention.

Yes. You can attach any structured metadata to a log entry, including request payloads and response bodies. Just pass them as properties in your log call. Be mindful of sensitive data and your monthly log quota when logging full payloads.
Yes. While native SDKs are available for JavaScript and Flutter, the LogMonitor HTTP API accepts log data via standard HTTP POST requests. You can send logs from Python, Go, Ruby, Java, or any language that can make HTTP calls.
Logs appear in the Live Console within seconds of being sent. The SDK batches entries for efficiency, but delivery is near real-time so you can monitor active incidents as they unfold.
LogMonitor focuses on log streaming and search. You can monitor your Live Console for specific status codes and error patterns, filtering by severity, endpoint, or custom metadata to quickly identify failing requests.
Cloud provider logging tools scatter your logs across services, regions, and accounts. LogMonitor gives you a single, clean dashboard with real-time streaming and instant search across all your APIs regardless of where they are hosted.
It depends on your traffic volume. The Pro plan covers 1 million logs per month, which handles roughly 30,000 requests per day. The Scale plan covers 5 million logs for higher-traffic APIs. You can also selectively log only errors or slow requests to optimize your quota.
