Atopsar-Plot

Graphically represent the historical system resource consumption like CPU, disk, memory and network usage in a terminal.

Example output

Features

Atopsar-Plot allows graphing various historic system information directly in the terminal. It is based on logs written by atop. The following information can be plotted:

  • %CPU_busy: CPU busy time in percent. Multiple cores are averaged to 100%
  • %DSK_busy: Disk activity in percent (see --disk flag)
  • %MEM_used: Used memory in percent ((memtotal - memfree - buffers - cached) / memtotal * 100)
  • %NET_busy: Network usage in percent. Formula: max(imbps, ombps) / maxmbps_if_ (see --iface flag)

Plots for previous days can be plotted with the parameter --day -1, --day -2, ... or with alternative format YYYY-MM-DD

Resource usage alerts

Resource usage alerts can be sent by specifying an --alert-mail. For this to work, the package mailx must be installed and configured to allow sending mails. You may create a cron job for alerts. Keep in mind that atop averages resource consumption over the whole time granularity (default is 10 minutes). With the default --alert-threshold (70) an alert will be generated if any of the monitored resources exceeds 70% of its maximum capacity.

Additionally, there is a hard disk space allocation alert for the root filesystem "/" whose threshold can be set with --alert-disk-threshold.

# crontab -e
