reslogd is a lightweight Linux daemon that logs system resource usage (CPU, RAM, and process count) to a log file every minute.

• Runs as a daemon in the background
• Logs:
  • CPU usage (%)
  • RAM used (MiB)
  • Number of active processes
• Logs saved to /var/log/reslogd.log
• PID saved to a file (default: /run/reslogd.pid)
• Supports log rotation and init script

sudo make

This will:

• Build the binary (/usr/bin/reslogd)
• Copy the logrotate config to /etc/logrotate.d/reslogd
• Copy the init script to /etc/init.d/reslogd

sudo /usr/bin/reslogd

Or use the init system:

sudo service reslogd start

A sample config is installed to /etc/logrotate.d/reslogd. You can rotate logs manually:

sudo logrotate -f /etc/logrotate.d/reslogd

sudo rm /usr/bin/reslogd
sudo rm /etc/init.d/reslogd
sudo rm /etc/logrotate.d/reslogd
sudo rm /var/log/reslogd.log
sudo rm /run/reslogd.pid
