Glances -- Eye on your system
|
||||
=============================
|
||||
|
||||
## Description
|
||||
|
||||
Glances is a CLI curses based monitoring tools for both GNU/Linux and BSD.
|
||||
|
||||
Glances uses the libstatgrab library to get informations from your system.
|
||||
Glances is developped in Python and uses the python-statgrab lib.
|
||||
|
||||
|
||||
|
||||
## Installation
|
||||
|
||||
Glances use a standard GNU style installer:
|
||||
|
||||
$ tar zxvf glances-v1.0.tar.gz
|
||||
$ cd glances
|
||||
$ ./configure
|
||||
$ make
|
||||
$ sudo make install
|
||||
|
||||
Pre-requisites:
|
||||
|
||||
* Python 2.6+ (not tested with Python 3)
|
||||
* python-statgrab 0.5+ (did not work with python-statgrab 0.5)
|
||||
|
||||
Notes: The Debian Squeeze repos only include the python-statgrab 0.4.
|
||||
You had to install the version 0.5 using the following commands:
|
||||
|
||||
$ sudo apt-get install libstatgrab-dev
|
||||
$ wget http://ftp.uk.i-scream.org/sites/ftp.i-scream.org/pub/i-scream/pystatgrab/pystatgrab-0.5.tar.gz
|
||||
$ tar zxvf pystatgrab-0.5.tar.gz
|
||||
$ cd pystatgrab-0.5/
|
||||
$ ./setup.py build
|
||||
$ sudo ./setup.py install
|
||||
|
||||
## Running
|
||||
|
||||
Easy:
|
||||
|
||||
$ glances.py
|
||||
|
||||
## User guide
|
||||
|
||||
By default, stats are refrsh every second, to change this setting, you can
|
||||
use the -t option. For exemple to set the refrech rate to 5 seconds:
|
||||
|
||||
$ glances.py -t 5
|
||||
|
||||
Importants stats are colored:
|
||||
|
||||
* GREEN: stat counter is < 50%
|
||||
* BLUE: stat counter is > 50% and < 70%
|
||||
* MAGENTA: stat counter is > 70% and < 90%
|
||||
* RED: stat counter is > 90%
|
||||
|
||||
When Glances is running, you can press:
|
||||
|
||||
* 'a' to set the automatic mode. The process list is sorted automatically
|
||||
|
||||
If CPU > 70%, sort by process CPU consomption
|
||||
|
||||
If MEM > 70%, sort by process size
|
||||
|
||||
* 'c' the processes list is sorted by CPU consomption
|
||||
* 'm' the processes list is sorted by process size
|
||||
* 'q' Exit
|
||||
|
||||
## Limitation
|
||||
|
||||
The current version of the python-statgrab API can not retrieve the file
|
||||
system statistics.
|
||||
https://bugs.launchpad.net/ubuntu/+source/libstatgrab/+bug/886783
|
||||
|
||||
## Todo
|
||||
|
||||
You are welcome to contribute to this software.
|
||||
|
||||
* Packaging for Debian, Ubuntu, Fedora, Redhat, BSD...
|
||||
* Check the needed Python library in the configure.ac
|
||||
* Add file system stats when the python-statgrab is corrected
|
||||
* Add a user guide window
