#-This simple plugin figures out how many users are logged into the linux box and writes it to a simple Gauge-style graph.
|
||
|
|
#-The plugin takes advantage of the linux 'who' command.
|
||
|
|
# -The who command is cut into the first field (to the first space).
|
||
|
|
# -This is the username field.
|
||
|
|
# -Unfortunately this will log multiples for the same user if multiple terminals are open.
|
||
|
|
# -Then we need to sort the results since uniq only deals with unique elements next in line to each other.
|
||
|
|
# -We find the uniqe usernames logged on.
|
||
|
|
# -Then wc -l counts how many lines (users) we're left with.
