\fBglances\fP [OPTIONS]
|
|
.SH DESCRIPTION
|
|
.sp
|
|
\fBglances\fP is a cross\-platform curses\-based monitoring tool which aims
|
|
to present a maximum of information in a minimum of space, ideally to
|
|
fit in a classical 80x24 terminal or higher to have additional
|
|
information. It can adapt dynamically the displayed information
|
|
depending on the terminal size. It can also work in client/server mode.
|
|
Remote monitoring could be done via terminal or web interface.
|
|
.sp
|
|
\fBglances\fP is written in Python and uses the \fIpsutil\fP library to get
|
|
information from your system.

Each plugin, export module and application monitoring process (AMP) can
|
|
have a section. Below an example for the CPU plugin:
|
|
.INDENT 0.0
|
|
.INDENT 3.5
|
|
.sp
|
|
.nf
|
|
.ft C
|

|
|
user_critical=90
|
|
iowait_careful=50
|
|
iowait_warning=70
|
|
iowait_critical=90
|
|
system_careful=50
|
|
system_warning=70
|
|
system_critical=90
|
|
steal_careful=50
|
|
steal_warning=70

an InfluxDB export module:

.INDENT 0.0
|
|
.INDENT 3.5
|
|
.sp
|
|
.nf
|
|
.ft C
|

or a Nginx AMP:
|
|
.INDENT 0.0
|
|
.INDENT 3.5
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
[amp_nginx]
|
|
# Nginx status page should be enable (https://easyengine.io/tutorials/nginx/status\-page/)

|

.ft P
|
|
.fi
|
|
.UNINDENT
|
|
.UNINDENT
|
|
.sp
|
|
With Glances 3.0 or higher it is also possible to use dynamic configuration
|
|
value using system command. For example, if you to set the prefix of an
|
|
InfluxDB export to the current hostname, use:
|
|
.INDENT 0.0
|
|
.INDENT 3.5
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
[influxdb]
|
|
\&...
|
|
prefix=\(gahostname\(ga
|
|
.ft P
|
|
.fi
|
|
.UNINDENT
|
|
.UNINDENT
|
|
.sp
|
|
Or if you want to add the Operating System name as a tag:
|
|
.INDENT 0.0
|
|
.INDENT 3.5
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
[influxdb]
|
|
\&...
|
|
tags=system:\(gauname \-a\(ga
|
|

.SH LOGGING
|
|
.sp
|
|
Glances logs all of its internal messages to a log file.
|
|
.sp
|
|
\fBDEBUG\fP messages can been logged using the \fB\-d\fP option on the command
|
|
line.
|
|
.sp
|
|
By default, the \fBglances\-USERNAME.log\fP file is under the temporary directory:
|
|
.TS
|
|
center;
|
|
|l|l|.
|
|
_
|
|
T{
|
|
\fB*nix\fP
|
|
T} T{
|
|
/tmp
|
|
T}
|
|
_
|
|
T{
|
|
\fBWindows\fP
|
|
T} T{
|
|
%TEMP%
|
|
T}
|
|
_
|
|
.TE
|
|
.INDENT 0.0
|
|
.IP \(bu 2
|
|
On Windows XP, \fB%TEMP%\fP is: \fBC:\eDocuments and Settings\e<USERNAME>\eLocal Settings\eTemp\fP\&.
|
|
.IP \(bu 2
|
|
On Windows Vista and later: \fBC:\eUsers\e<USERNAME>\eAppData\eLocal\eTemp\fP\&.
|
|

|
.sp
|
|
If you want to use another system path or change the log message, you
|
|
can use your own logger configuration. First of all, you have to create
|
|
a \fBglances.json\fP file with, for example, the following content (JSON
|
|
format):
|
|
.INDENT 0.0
|
|
.INDENT 3.5
