Glances Monitor

Glances - An eye on your system

 apt-get install glances

To start glances simply type glances in terminal.



In glances you’ll see a lot of information about the resources of your system: CPU, Load, Memory, Swap Network, Disk I/O and Processes all in one page, by default the color code means:

GREEN : the statistic is “OK”
BLUE : the statistic is “CAREFUL” (to watch)
VIOLET : the statistic is “WARNING” (alert)
RED : the statistic is “CRITICAL” (critical)

When Glances is running, you can press some special keys to give commands to it:

c: Sort processes by CPU%  
m: Sort processes by MEM%  
p: Sort processes by name  
i: Sort processes by IO Rate  
d: Show/hide disk I/O stats  
f: Show/hide file system stats  
n: Show/hide network stats  
s: Show/hide sensors stats  
b: Bit/s or Byte/s for network IO  
w: Delete warning logs  
x: Delete warning and critical logs  
1: Global CPU or Per Core stats  
h: Show/hide this help message  
q: Quit (Esc and Ctrl-C also work)  
l: Show/hide log messages

System Heat Monitoring

If you type glances --help you will find ( -e Enable the sensors module (Linux-only) )

glances -e

Configuration file

You can set your thresholds in Glances configuration file, on GNU/Linux, the default configuration file is located in /etc/glances/glances.conf.

Client/server mode

Another interesting feature of this monitoring tool is that you can start it in server mode just typing glances -s, this will give an output like Glances server is running on 0.0.0.0:61209 and now you can connect to it from another computer using glances -c @server where @server is the IP address or hostname of the server.
Glances uses a XML/RPC server and can be used by another client software. In server mode, you can set the bind address (-B ADDRESS) and listening TCP port (-p PORT), the default binding address is 0.0.0.0 (Glances will listen on all the networks interfaces) and TCP port is 61209. In client mode, you can set the TCP port of the server (-p port). In client/server mode, limits are set by the server side. The version 1.6 introduces a optional password to access to the server (-P password) that if set on the server must be used also on the client.
