.SH NAME
|
|
\fBbyobu\-ugraph\fP \- helper script for notification history graphs
|
|
|
|
.SH DESCRIPTION
|
|
\fBbyobu\-ugraph\fP is a helper script that can be used to create history graphs
|
|
|
|
.SH USAGE
|
|
\fBbyobu\-ugraph\fP [options] [command [args...]]
|
|
|
|
.SH OPTIONS
|
|
-f <file> : File to read data points from. (only required if no command specified).
|
|
-h : Show this help.
|
|
-m <num> : Minimum value (default=$min_default).
|
|
-n : Supress output of newline character.
|
|
-p <points> : Specify number of data points in graph (default=$points_default).
|
|
-r : Do not rotate file <file> (default is to rotate). Option implies file <file> should not be written to so a command cannot follow script options in this case.
|
|
-t <theme> : 'byobu-ulevel' theme to use (default=$theme_default).
|
|
-x <num> : Maximum value (default=$max_default).
|
|
|
|
.SH EXAMPLES
|
|
Using byobu-ugraph to run a command, rotate log and display graph.
|
|
|
|
Here we specify a command to display available memory. Trailing echo adds a required newline Note no filename specified.
|
|
|
|
byobu-ugraph "(/usr/lib/byobu/mem_used | sed -e 's/% //g';echo)"
|
|
|
|
Using byobu-ugraph just to rotate log and display the graph
|
|
|
|
file=/tmp/load.dat
|
|
awk '{ print $1}' /proc/loadavg >> $file
|
|
# Note: we need to specify what we consider to be a "reasonable" maximum load
|
|
byobu-ugraph -m 3.0 -f $file
|
|
|
|
.SH NOTES
|
|
|
|
If you specify 'command', care must be taken with shell quoting to avoid expansion prior to this script running the command.
|
|
|
|
If '-r' is not specified, the file <file> will be rotated such that at most <points> lines are retained on each invocation of this script.
