byobu-ugraph is a helper script that can be used to create history graphsUsage
byobu-ugraph [options] [command [args...]]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).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 $fileNotes
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.See Also
