Server Monitoring

Appliku continuously monitors your servers and displays key metrics on the server detail page in the dashboard.

Monitored Metrics

CPU Usage

Appliku tracks CPU utilization as a percentage. High CPU usage sustained over long periods may indicate your application needs optimization or a larger server.

Memory (RAM) Usage

Current memory usage is displayed as both an absolute value and a percentage of total available RAM.

Appliku triggers an alert when RAM usage exceeds 80% of total available memory. If you receive this alert, consider:

• Reducing the number of applications running on the server
• Upgrading to a server with more RAM
• Optimizing your application's memory consumption
• Reducing build concurrency (see below)

Disk Usage

Disk usage is monitored to ensure your server does not run out of storage. Docker images and containers can accumulate over time. Appliku performs periodic Docker cleanup to reclaim disk space, but very active servers with frequent deployments may need larger disks.

Uptime

Server uptime is tracked so you can see how long the server has been running since its last restart.

Viewing Server Metrics

1. Open the Appliku dashboard
2. Navigate to the Servers tab
3. Click on a server to open its detail page
4. Server metrics are displayed on the overview section

RAM Spikes During Builds

This is normal behavior

RAM spikes during deployment builds are expected, especially for JavaScript and TypeScript projects with many dependencies. The npm install or yarn install step can temporarily consume a large amount of memory.

If you see RAM alerts only during deployments but your server is otherwise healthy, this is not a cause for concern. To reduce build-time memory pressure, you can:

• Use a larger server -- more RAM gives builds more headroom
• Reduce build concurrency -- if multiple applications are building at the same time, they compete for memory. Stagger deployments or limit concurrent builds
• Use a separate build server -- in a cluster setup, you can designate a dedicated build server so builds do not affect running applications

Alerts

When a metric exceeds its threshold, Appliku displays a warning on the server detail page and in the servers list. The current alert thresholds are:

Metric	Alert Threshold
RAM usage	> 80%

Keeping your servers within healthy resource limits ensures reliable deployments and stable application performance.
