FiveNines Docker container monitoring dashboard

Per-Container Metrics

CPU, memory, network I/O, and disk read/write for every running container - individually, not just host-level aggregates.

5-Second Collection

Catch the CPU spike that lasted 15 seconds and crashed your app - the kind of event that 60-second polling completely misses.

Container Health Tracking

Know instantly when a container stops, restarts, or enters an unhealthy state. Correlate restarts with the memory spike that caused them.

Alerting That Actually Works

Set per-container thresholds for any metric. Get notified via email, Slack, Telegram, Discord, Pushover, or webhooks when a container exceeds CPU limits, runs low on memory, or stops responding.

No alert fatigue - you define the thresholds that matter to your infrastructure, not some ML model's opinion of what looks "anomalous."

Historical Data & Trends

Unlike docker stats, Fivenines stores your container metrics with up to 24 months of retention (depending on your plan). Spot memory leaks that develop over days, track resource growth as traffic scales, and plan capacity based on real data.

How It Compares

Approach Setup Time Per-Container Alerting Retention
docker stats 0 min Live only
cAdvisor + Prometheus + Grafana 2-4 hours Manual config Self-managed
Datadog 30 min Expensive at scale
Fivenines 2 min Built-in Up to 24 months

Setup Takes One Command

curl -s https://fivenines.io/install | bash

The agent auto-detects Docker and starts collecting container metrics immediately. No additional configuration needed. See your containers in the dashboard within 60 seconds of installation.

Frequently Asked Questions

Does the agent run inside a container or on the host?
The agent runs on the host. It communicates with the Docker daemon to collect per-container metrics without requiring any changes to your containers or Compose files.
What Docker metrics are tracked?
CPU usage (%), memory usage (used/limit), network I/O (bytes in/out), block I/O (read/write), container status, restart count, and uptime.
Does it work with Docker Compose and Docker Swarm?
Yes. The agent monitors all containers on the host regardless of how they were deployed - standalone, Compose, or Swarm.
Will it slow down my containers?
The agent is lightweight and runs with minimal overhead. It reads metrics from the Docker API, which has negligible performance impact on your containers.
Can I monitor containers across multiple servers?
Yes. Install the agent on each host and see all containers from all servers in a single dashboard.
