Glances is a cross-platform monitoring tool which aims to present a large amount of monitoring information through a curses or Web based interface. The information dynamically adapts depending on the size of the user interface.
Some of the information that Glances presents isn’t displayed in the image above. For example, warning or critical alerts are not displayed. This is a consequence of Glances dynamically changing the displayed information based on the size of our Hyper terminal window.
We really like its support for monitoring remote machines via its XML-RPC server. There’s also a RESTful JDSON API.
Information displayed by Glances includes:
- CPU usage. If enough horizontal space is available, extended CPU information is displayed. In the same way as the classic top utility, pressing the 1 key shows CPU usage for each individual core.
- GPU usage (in the image above, Glances shows our test machine hosts GeForce graphics card, detailing processor usage, memory usage, and temperature.
- Memory usage. Glances uses two columns: one for the RAM and one for the SWAP.
- Load on the system.
- File system – displays the used and total file system disk space. The unit is adapted dynamically.
- Filesystem I/O – displays the disk I/O throughput. The unit is also adapted dynamically.
- Network I/O. Glances displays the network interface bit rate. The unit is again adapted dynamically (bit/s, kbit/s, Mbit/s, etc). The module also shows extended information about network connections.
- Wi-Fi – displays the Wi-Fi hotspot names and signal quality.
- Ports – provides a list of hosts/port and URL to scan.
- List of tasks.
Glances lets you toggle modules on and off. With a few keyboard shortcuts you can show/hide filesystem stats, sensors stats, disk I/O stats, alert logs, and network stats. Pressing h from the Glances interface displays a complete list of the available keyboard shortcuts.
