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.
|
||||
|
||||
|
||||
|
||||
## Installation
|
||||
|
||||
### From package manager
|
||||
|
||||
Packages exist for Arch, Fedora, Redhat ...
|
||||
|
||||
### From source
|
||||
|
||||
Get the latest version:
|
||||
|
||||
$ wget https://github.com/downloads/nicolargo/glances/glances-1.3.5.tar.gz
|
||||
|
||||
Glances use a standard GNU style installer:
|
||||
|
||||
$ tar zxvf glances-1.3.5.tar.gz
|
||||
$ cd glances-1.3.5
|
||||
$ ./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
|
||||
|
||||
|
||||
|
||||
The header shows the Glances version, the host name and the operating
|
||||
system name, version and architecture.
|
||||
|
||||
### CPU
|
||||
|
||||
|
||||
|
||||
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
|
||||
|
||||
|
||||
|
||||
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
|
||||
|
||||
|
||||
|
||||
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
|
||||
|
||||
|
||||
|
||||
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
|
||||
|
||||
|
||||
|
||||
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
|
||||
|
||||
|
||||
|
||||
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
|
||||
|
||||
|
||||
|
||||
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
|
||||
|
||||
|
||||
|
||||
Glances displays a caption and the current time/date.
|
||||
|
||||

|
||||
|
||||
You are welcome to contribute to this software.
|
||||
|
||||
* Packaging for Debian, Ubuntu, BSD...
|
||||
* Check the needed Python library in the configure.ac
