One platform for metrics, logs, APM & real user experience
Watchlog brings your infrastructure metrics, application traces, live logs, API monitors, and real‑user telemetry together—so you can find issues faster, ship with confidence, and scale without surprises.
Why teams choose Watchlog
Stop juggling multiple tools. Watchlog centralizes everything you need to observe system health, track performance, and understand user experience—on one elegant dashboard.
See issues before users do
Proactive alerts on latency, error spikes, log patterns, and API failures let you respond before incidents escalate.
Trace to root cause fast
Correlate metrics, traces, and logs across services to pinpoint the exact commit, route, or query causing trouble.
Measure real user impact
RUM shows what actual users experience across pages and routes, complete with normalized paths and performance timings.
Works with your stack
First‑class integrations for Node.js, Flask, Django, Laravel, FastAPI, PM2, Docker, Nginx, MongoDB, PostgreSQL, MySQL, and Redis.
Secure by design
Isolated Enterprise deployments with custom domain & branding. Access is account‑controlled—no public sign‑ups for Enterprise.
Built to scale
Lightweight agent, efficient storage, and dashboards that stay snappy whether you monitor one app or hundreds.
How Watchlog works
Watchlog uses a lightweight agent and language‑specific SDKs to capture metrics, logs, traces, and user telemetry. Data flows to your dedicated Watchlog server, where dashboards, alerts, and analytics turn signals into action.
1) Install the agent & SDK
Drop‑in setup for servers and frameworks. Send metrics and events in minutes.
2) Stream data
Metrics every few seconds, live logs, APM traces, API checks, and browser RUM are ingested continuously.
3) Act with clarity
Dashboards, search, thresholds, and webhooks surface what matters so you can fix fast and move on.
Everything you need in one place
Watchlog brings these pillars together so your team can debug in one flow instead of switching tabs all day.
APM (Application Performance Monitoring)
- SDKs for Node.js, Flask, Django, Laravel, and FastAPI
- Auto‑instrumentation for Express and NestJS via middleware/interceptors
- Trends: requests, errors, avg/max duration, memory
- Tables: top requests, errors, slowest endpoints
- Sampling and low‑overhead collection
Logs (live & searchable)
- Tail and search logs in real time
- Group logs by service, level, and patterns
- Watchlist for important log lines
- Browse with filters by text, level, and time
- Side panel drill‑downs for context
Metrics & Integrations
- Server metrics: CPU, memory, disk, network, connections, latency, IP
- Service integrations: PM2, Docker, Nginx
- Databases: MongoDB, PostgreSQL (with pg_stat_statements), MySQL, Redis
- Custom metrics & events from Node, Python, and PHP SDKs
- Kubernetes clusters, nodes, and pods overview (Beta)
API Monitoring
- Health and latency checks for critical endpoints
- Threshold‑based alerting on status codes and response time
- Per‑route insights with normalized paths
- Historical trends to catch regressions
Alerts & Webhooks
- Flexible thresholds on metrics, errors, and logs
- Send alerts to Custom endpoints, Telegram, or Slack
- Smart grouping to reduce noise
- Webhook payloads with rich context for quick automations
Real User Monitoring (RUM) — Beta
- Page‑level performance metrics from the browser
- Automatic normalizedPath detection
- Separate high‑volume datastore for RUM analytics
- Understand the impact of changes on actual users
Architecture that respects your scale
- • Lightweight agent built for steady, low‑latency delivery
- • Efficient storage for metrics, logs, and traces
- • Dashboards optimized for large datasets
- • Designed for multi‑service, multi‑environment setups
Security & privacy by default
- • Enterprise deployments run on a dedicated server with your custom domain & branding
- • Access is account‑controlled by your admin—no open sign‑ups
- • Webhook endpoints allow routing alerts into your secure automations
- • Data residency flexibility based on your server location
Proven across your lifecycle
Backend performance
Trace slow endpoints and database queries, and validate improvements with APM trends.
Production stability
Spot error spikes, tail logs in real time, and ship a fix before users notice.
API reliability
Guard critical routes with uptime checks, SLAs, and latency thresholds.
Kubernetes visibility
Understand cluster health across nodes and pods, including restarts and readiness (Beta).
Release validation
Compare RUM & APM metrics before/after deploys to ensure better real‑world performance.
Cost control
Consolidate tools and reduce overhead—one platform, one invoice.

Frequently asked questions
Do you offer a trial?
Yes — start a 30‑day free trial with full access. No credit card required to begin.
How is Watchlog different from stitching multiple tools?
Watchlog unifies metrics, logs, traces, API checks, and real‑user monitoring in one place so you can correlate signals instantly—no context switching.
Do we need to host Watchlog ourselves?
For Enterprise, we provision and manage a dedicated server for your company under your subdomain. You get isolation, branding, and full features without maintenance overhead.
Which stacks are supported for APM?
Node.js (Express, NestJS), Python (Flask, Django, FastAPI), and PHP (Laravel). SDKs surface trends, slow endpoints, errors, and memory usage.
What about front‑end performance?
RUM (Beta) captures page‑level timings, errors, and route performance with normalized paths. High‑volume RUM data is handled in a dedicated datastore for speed and cost control.
