+Glances -- Eye on your system
+=============================
+
+## Description
+
+Glances is a CLI curses based monitoring tool for GNU/Linux or BSD OS.
+
+Glances uses the libstatgrab library to get information from your system.
+It is developed in Python and uses the python-statgrab lib.
+
+![screenshot](https://github.com/nicolargo/glances/raw/master/screenshot.png)
+
+## Installation
+
+### From package manager
+
+Packages exist for Arch, Fedora, Redhat ...
+
+### From source
+
+Get the latest version:
+
+	$ wget https://github.com/downloads/nicolargo/glances/glances-1.3.6.tar.gz
+
+Glances use a standard GNU style installer:
+
+	$ tar zxvf glances-1.3.6.tar.gz
+	$ cd glances-1.3.6
+	$ ./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 0.4)
+
+Notes: For Debian.
+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 pkg-config python-dev make
+	$ 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
+
+Notes: For Ubuntu 10.04 and 10.10. 
+The instruction to install the version 0.5 are here: 
+https://github.com/nicolargo/glances/issues/5#issuecomment-3033194
+
+## Running
+
+Easy:
+
+	$ glances.py
+
+## User guide
+
+By default, stats are refreshed 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 "OK"
+* BLUE:    stat counter is "CAREFUL"
+* MAGENTA: stat counter is "WARNING"
+* RED:     stat counter is "CRITICAL"
+
+When Glances is running, you can press:
+
+* 'h' to display an help message whith the keys you can press
+* 'a' to set the automatic mode. The processes are sorted automatically
+
+    If CPU > 70%, sort by process "CPU consumption"
+
+    If MEM > 70%, sort by process "memory size"
+
+* 'c' to sort the processes list by CPU consumption
+* 'd' Disable or enable the disk IO stats
+* 'f' Disable or enable the file system stats
+* 'm' to sort the processes list by process size
+* 'n' Disable or enable the network interfaces stats
+* 'q' Exit
+
+### Header
+
+![screenshot](https://github.com/nicolargo/glances/raw/master/doc/header.png)
+
+The header shows the Glances version, the host name and the operating 
+system name, version and architecture.
+
+### CPU
+
+![screenshot](https://github.com/nicolargo/glances/raw/master/doc/cpu.png)
+
+The CPU states are shown as a percentage and for the configured refresh 
+time.
+
+If user|kernel|nice CPU is < 50%, then status is set to "OK".
+
+If user|kernel|nice CPU is > 50%, then status is set to "CAREFUL".
+
+If user|kernel|nice CPU is > 70%, then status is set to "WARNING".
+
+If user|kernel|nice CPU is > 90%, then status is set to "CRITICAL".
+
+### Load
+
+![screenshot](https://github.com/nicolargo/glances/raw/master/doc/load.png)
+
+On the Nosheep blog, Zach defines the average load: "In short it is the 
+average sum of the number of processes waiting in the run-queue plus the 
+number currently executing over 1, 5, and 15 minute time periods."
+
+Glances gets the number of CPU cores to adapt the alerts. With Glances, 
+alerts on average load are only set on 5 and 15 mins. 
+
+If average load is < O.7*Core, then status is set to "OK".
+
+If average load is > O.7*Core, then status is set to "CAREFUL".
+
+If average load is > 1*Core, then status is set to "WARNING".
+
+If average load is > 5*Core, then status is set to "CRITICAL".
+
+### Memory
+
+![screenshot](https://github.com/nicolargo/glances/raw/master/doc/mem.png)
+
+Glances uses tree columns: memory (RAM), swap and "real".
+
+Real used memory is: used - cache.
+
+Real free memory is: free + cache.
+
+With Glances, alerts are only set for on used swap and real memory.
+
+If memory is < 50%, then status is set to "OK".
+
+If memory is > 50%, then status is set to "CAREFUL".
+
+If memory is > 70%, then status is set to "WARNING".
+
+If memory is > 90%, then status is set to "CRITICAL".
+
+### Network bit rate
+
+![screenshot](https://github.com/nicolargo/glances/raw/master/doc/network.png)
+
+Glances display the network interface bit rate. The unit is adapted 
+dynamicaly (bits per second, Kbits per second, Mbits per second...).
+
+Alerts are set only if the network interface maximum speed is available.
+
+If bitrate is < 50%, then status is set to "OK".
+
+If bitrate is > 50%, then status is set to "CAREFUL".
+
+If bitrate is > 70%, then status is set to "WARNING".
+
+If bitrate is > 90%, then status is set to "CRITICAL".
+
+For exemple, on a 100 Mbps Ethernet interface, the warning status is set 
+if the bit rate is higher than 70 Mbps.
+
+### Disk I/O
+
+![screenshot](https://github.com/nicolargo/glances/raw/master/doc/diskio.png)
+
+Glances display the disk I/O throughput. The unit is adapted dynamicaly 
+(bytes per second, Kbytes per second, Mbytes per second...).
+
+There is no alert on this information.
+
+### Filesystem
+
+![screenshot](https://github.com/nicolargo/glances/raw/master/doc/fs.png)
+
+Glances display the total and used filesytem disk space. The unit is 
+adapted dynamicaly (bytes per second, Kbytes per second, Mbytes per 
+second...).
+
+Alerts are set for used disk space:
+
+If disk used is < 50%, then status is set to "OK".
+
+If disk used is > 50%, then status is set to "CAREFUL".
+
+If disk used is > 70%, then status is set to "WARNING".
+
+If disk used is > 90%, then status is set to "CRITICAL".
+
+### Processes
+
+![screenshot](https://github.com/nicolargo/glances/raw/master/doc/processlist.png)
+
+Glances displays a summary and a list of processes.
+
+By default (or if you hit the 'a' key) the process list is automaticaly 
+sorted by CPU of memory consumption.
+
+The number of processes in the list is adapted to the screen size.
+
+### Footer
+
+![screenshot](https://github.com/nicolargo/glances/raw/master/doc/footer.png)
+
+Glances displays a caption and the current time/date.
+
+## Localisation
+
+To generate french locale execute as root or sudo :
+i18n_francais_generate.sh
+
+To generate spanish locale execute as root or sudo :
+i18n_espanol_generate.sh
+
+## Todo
+
+You are welcome to contribute to this software.
+
+* Packaging for Debian, Ubuntu, BSD...
+* Check the needed Python library in the configure.ac
+* Add file system stats when the python-statgrab is corrected
