Collectl


NAME

       collectl - Collects data that describes the current system status.

SYNOPSIS

       Record Mode - read data from live system and write to file or display on terminal

       collectl [-f file] [options]

       Playback Mode - read data from one or more raw data files and display on terminal

       collectl -p file1 [file2 ...] [options]

Playback Mode

There are a couple of things to remember about playback:

    You need a data file. When run as a deamon via service collectl start data will be 
    written to /var/log/collectl by default.
    You can playback a subset of data by inclusion of the -s switch
    Just about any formatting switches you can use interactively you can use during playback
    You can select a subset of the time period with --from and --thru

Example 1:

root@fedora collectl]# collectl -p fedora-20121207-220643.raw.gz --top --from 22:24 --thru 22:25
