Atop: Real-Time Server Monitoring

Atop is an open-source monitoring tool for monitoring and managing various server resources like CPU, memory, disk, network and processes. It can monitor in real-time and also log data for long-term analysis.

What is Atop?

Atop is an open-source monitoring tool for Linux systems used to monitor and manage various server resources including CPU, memory, disk drives, network and processes in real-time. It can show both the current status as well as long term statistics of these resources.

Some key features of Atop include:

  • Real-time monitoring of CPU, memory, disk, network, swap usage/performance.
  • Logger mode to log data for long-term analysis.
  • Interactive interface to inspect load on processes, disks.
  • Alerts based on various thresholds.
  • Easy visualization of data using ASCII graphs.
  • Log rotation based on time or file size.
  • Supports various outputs like ASCII, raw data or HTTP publish.

Atop is useful for system administrators and developers to monitor system resources, performance and troubleshoot bottle necks. It provides more detailed statistics compared to basic tools like top, vmstat or iostat. The logging features also help correlate performance data with events.
