In addition to collecting job resource information based upon machines used, you can gather this information based upon an event or time that you specify. For example, you may want to collect accounting information at the end of every work shift or at the end of every week or month. To collect accounting information on all machines in this manner, use the llctl command with the capture parameter:
llctl -g capture eventname
eventname is any string of continuous characters (no white space is allowed) that defines the event about which you are collecting accounting data. For example, if you were collecting accounting data on the graveyard work shift, your command could be:
llctl -g capture graveyard
This command allows you to obtain a snapshot of the resources consumed by active jobs up to and including the moment when you issued the command. If you want to capture this type of information on a regular basis, you can set up a crontab entry to invoke this command regularly. For example:
# sample crontab for accounting # shift crontab 94/8/5 # # Set up three shifts, first, second, and graveyard shift. # Crontab entries indicate the end of shift. # #M H d m day command # 00 08 * * * /u/loadl/bin/llctl -g capture graveyard 00 16 * * * /u/loadl/bin/llctl -g capture first 00 00 * * * /u/loadl/bin/llctl -g capture second
