WATCHLOG PRODUCT · APPLICATION
Find slowdowns before
your users do.
Distributed tracing, service dependency maps, latency percentiles, and error tracking for every backend service — automatically instrumented.
THE PROBLEM
Backend latency is invisible without traces.
When users report slowness, engineers face a guessing game across logs, metrics, and service dashboards. Without distributed tracing, finding the specific service, database query, or downstream call that caused a latency spike takes hours — not minutes.
No visibility into request paths
Logs tell you something went wrong. Traces tell you where, why, and for how long.
Slow queries stay hidden
A 400ms database call buried inside a 450ms request is invisible until tracing surfaces it.
Service dependencies are a mystery
Which services call each other? Which ones degrade under load? Without a service map, nobody knows.
WHAT'S MONITORED
Everything Application Performance Monitoring captures.
Real signals collected by the Watchlog Agent — available in your dashboard within 60 seconds of enabling.
Distributed Tracing
Full span waterfall for every request — from API gateway to database query and back.
Service Dependency Map
Auto-generated topology showing every service, its dependencies, and their health status.
Latency Percentiles
p50, p95, and p99 latency tracked per endpoint and per service with historical trending.
Error Tracking
Exceptions, stack traces, and error rate per service — with deploy marker correlation.
Slow Query Detection
Database calls exceeding threshold surfaced automatically in the span waterfall.
OpenTelemetry Support
Send traces from any OpenTelemetry-instrumented service directly to Watchlog.
LIVE VIEW
Trace waterfall — live.
See every span, service, and database call for any request in your system.
CAPABILITIES
What Application Performance Monitoring gives you.
Full span waterfall
Every internal function call, database query, and external request shown as a timed span.
Auto-generated service map
Visualize your entire service topology without writing a single line of config.
Latency histogram
Understand the distribution of request latency — not just the average.
Deploy correlation
Error rate and latency changes automatically correlated against your deploy events.
Error group deduplication
Identical exceptions grouped and counted so you know which bugs matter most.
Endpoint performance table
Rank every route by p95 latency, error rate, and request volume in one table.
USE CASES
How engineering teams use Application Performance Monitoring.
Latency regression investigation
A deploy changed something. APM shows you exactly which endpoint got slower and which span is responsible.
N+1 query detection
APM surfaces repeated database calls in a single request trace — the classic N+1 pattern caught automatically.
Service dependency debugging
A downstream microservice starts timing out. APM shows its upstream callers, error rate, and impact scope.
Error rate spike response
Error rate climbs on /api/checkout. APM shows the exception, the stack trace, the span, and when it started.
PLATFORM FIT
Application Performance Monitoring inside the Watchlog platform.
APM connects with Log Monitoring for trace-to-log correlation, Infrastructure for host-level context, and AI Analysis for automated root cause when error rates spike.
QUICK START
Start Application Performance Monitoring in under 2 minutes.
No YAML. No complex configuration. The Watchlog Agent handles discovery automatically.
Install the Agent
One curl command on your host. The Watchlog Agent starts immediately.
sudo apiKey="$WATCHLOG_API_KEY" server="$WATCHLOG_SERVER" MEMORY="300M" bash -c "$(curl -L https://watchlog.io/ubuntu/watchlog-script.sh)"Configure OTLP Endpoint
Update your OpenTelemetry exporter endpoint to send traces to the Watchlog Agent.
