System Metrics
See how much of your servers is in use.
System > Metrics shows the same kind of charts as service metrics, for the machines themselves:
- CPU and Memory per server.
- Network: traffic through the servers.
- Disk I/O: read and write throughput.
Use Filter to pick the time range and the servers, and to switch between one line per server and a combined total. Each server's own page under System > Servers has a Metrics tab too.
What to watch
- Memory that stays above 85%: add a server, or set resource limits on the services that use the most.
- CPU spikes during builds are normal. If they hurt your services, lower the build settings.
- Disk space is the one that catches people. Images, build cache, logs and volumes all grow. A server that runs out of disk stops starting new replicas. Check with
df -hon the server, and see Troubleshooting.
Metrics are kept for 7 days.
