===== Glances =====



Glances is a cross-platform curses-based system monitoring tool written in Python.

see https://github.com/nicolargo/glances and https://github.com/nicolargo/glances/blob/master/docs/glances-doc.rst

Add my repository, [[nethserver|see how to do it]]

then install the module

  yum install nethserver-glances --enablerepo=stephdl

after that you need to launch the sensor detection

  sensors-detect

==== Usage ====
<WRAP center round important 60%>
For now there is no way to protect the Glances browser by a password, when this option will be available then I will implement it. Therefore Glances is accessible by the browser **only** from the local network. If it is an issue, then you can disable the service glances as written below, only the glances CLI will stay workable (launch it by 'glances' in a terminal)
</WRAP>

After the installation the service which control the web interface is launched, if you want to control it

  service glances stop  

can be also {restart,start,stop,status}

or you can use the neth way (enabled/disabled) <---once disabled you can still to use glances in a terminal

  config setprop glances status disabled
  signal-event nethserver-glances-update

each time you launch that signal-event, you will update glances and its dependencies

you can see the internal configuration database

  # config show glances 
  glances=service
  TCPPort=61208
  access=private
  status=enabled

once you have modified a property you need to launch a signal-event :     signal-event nethserver-glances-update

  * Private/Public access
by default glances is allowed only on the private side, eg : your local network.
if you want to modify it (private|public)
    config setprop glances access public
    signal-event nethserver-glances-update

  *in order to disable the glances web interface (and continue to use the CLI)
if you want to modify it (enabled|disabled)
    config setprop glances status disabled
    signal-event nethserver-glances-update

  *You can change the default TCP port**
if you want to modify it 
    config setprop glances TCPPort 55555
    signal-event nethserver-glances-update
    
The purpose is to see in direct the server activities (you can see raid, disk IO, sensors, bandwithd, memory, docker, ....)

Well a lot of good stuffs.

In order to use it go to Dashboard->Applications->Glances. It is a web service restricted on the private network. But if you don't like to use the web interface, then you can disable it and use only the CLI in your terminal (do simply 'glances')
