Watchlog
What it is
Watchlog is an observability platform that brings infrastructure metrics, logs, distributed traces, real user monitoring, uptime checks, synthetic journeys, integrations, AI analysis, and alerting together. Its agent gathers host metrics such as CPU, memory, disk, network, load, and processes. Log tools include full-text search, real-time alerts, and links between logs and traces. API checks can monitor HTTP services across regions, validate responses, track latency and SLAs, and monitor SSL certificate expiry. Alerts can go to Slack, Telegram, or webhooks. Listed integrations include MongoDB, PostgreSQL, MySQL, Redis, Elasticsearch, Docker, Kubernetes, NGINX, IIS, PM2, and GitLab. The free plan includes one monitoring agent, one API check, 10,000 custom events per month, limited log storage, and a basic dashboard. A 30-day trial requires no credit card to begin. Enterprise plans use dedicated infrastructure managed by Watchlog.
