Glances (All in One Place) – Advanced Real Time System Performance Monitoring Tool for Linux
Glances is a cross-platform curses-based system monitoring tool written in Python.
It uses the psutil library to retrieve information from your system.
It’s accommodating all in one place, It shows a maximum information in a minimal space through curses or a web-based interface.
The information dynamically adapts depending on the size of the user interface.
This is a best alternative to top/htop utility on GNU/Linux.
Glances is capable to monitor CPU usage, Memory usage, Swap usage, System Load Average, Process list, Network interface, Disk I/O, Raid, Sensors (CPU temperature), Battery, Filesystem Usage, Docker, Monitor, Alert, System info, Uptime, etc.,.
It can also work in client/server mode. Remote monitoring could be done via terminal.
Alternatively, you can monitor system performance through the built-in web user interface, and through the mobile interface.
You can export all system statistics to CSV, StatsD, InfluxDB, ElasticSearch or even RabbitMQ.
Glances also provides a dedicated Grafana dashboard.
By default the view limitations are configured as follows (careful= 50, alert= 70 and critical= 90) and you can adjust according to your requirements. The glances configuration file is located in
Glances Color Codes:
- GREEN : Ok
- BLUE : Careful
- VIOLET : Warning
- RED : Critical
