Containers & System Health

Docker Monitoring

Monitor Docker container health, resource usage, restart events, and network I/O in real time with zero configuration.

Why monitor Docker?

Docker is the industry standard for containerization, running microservices, CI/CD pipelines, and production workloads across millions of servers. Monitoring Docker containers is critical to detect resource leaks, prevent OOM kills, track restart loops, and ensure container health. Xitoring's Docker integration provides full visibility into every container running on your host.

1-minute metric collection intervals

Metrics

What we monitor

Container CPU Usage

CPU utilization percentage for each running container.

Container Memory Usage

Memory consumed by each container vs its memory limit.

Memory Limit

Configured memory limit and current usage percentage for each container.

Network RX/TX

Incoming and outgoing network traffic per container.

Block I/O Read/Write

Disk read and write operations per container.

Container Count

Total number of running, stopped, and paused containers.

Container Restarts

Number of restart events per container, indicating stability issues.

Container Health

Health check status for containers with configured HEALTHCHECK.

PIDs

Number of processes running inside each container.

Container Uptime

How long each container has been running since last start.

Triggers & Alerts

Configurable alert triggers

Set up custom triggers in your dashboard to get notified the moment Docker metrics cross your defined thresholds.

Container CPU Usage

warning

Fires when a container's CPU usage exceeds your threshold, indicating resource contention or runaway processes.

Container Memory Usage

critical

Triggers when memory approaches the container limit, risking OOM kills and container crashes.

Container Restarts

critical

Alerts when a container exceeds your restart count threshold, indicating instability or crash loops.

Container Health

critical

Fires when a container's HEALTHCHECK reports unhealthy status.

Network I/O Spike

warning

Triggers on abnormal network traffic patterns, which may indicate data exfiltration or DDoS.

Container Stopped

critical

Alerts when an expected container stops running unexpectedly.

Importance of Docker Monitoring

Docker containers are ephemeral by nature — they can crash, restart, and consume unbounded resources without warning. Without monitoring, memory leaks, CPU throttling, and crash loops can silently degrade your entire infrastructure.

Detect memory leaks before containers hit OOM limits
Identify crash loops and unstable containers immediately
Monitor resource allocation vs actual usage per container
Track network I/O for security and performance analysis
Ensure container health checks are passing consistently
