minmon 0.9.4

MINimum MONitor - display on stdout: timestamp, RAM and CPU usage, temperature, disk i/o and net i/o

usage: minmon [-h] [-V] [-s SEC] [-t] [-n] [-g] [-c] [-l LOG]

MINimum MONitor - display on stdout: timestamp, RAM and CPU usage, temperature, disk i/o and net i/o

minmon displays at fixed time intervals a line in stdout containing:

    1. date 'YYYY-mm-dd' (unless -t/--time is set)
    2. time 'HH:MM:SS'
    3. physical Memory % usage and Swap memory % usage
    4. CPU % usage and CPU Temperature in °C
    5. file system Read and Write rate in bytes/second
    6. network Download and Upload rate in bytes/second

Formats for 3. and 4. are:

    - numeric: two 2-digit decimal numbers, '**' = 100 (unless -g/--graphic is set)
    - graphic: a linear 0-100 graphic (unless -n/--numeric is set)

Formats for 5. an 6. are:

    - numeric: two 5-chars human-readable numbers (unless -g/--graphic is set)
    - graphic: a logarithmic 1-K-M-G-T graphic (unless -n/--numeric is set)

On overlap in graphics an 'X' is displayed.

As examples of 5-chars human-readable format:

    - '10K50' means 10.50 * 1024 = 10752 (about)
    - '287K6' means 287.6 * 1024 = 294502 (about)

Letters have the usual meaning:

    - 'K' = 2 ** 10 = 1024 ** 1 =          1024
    - 'M' = 2 ** 20 = 1024 ** 2 =       1048576
    - 'G' = 2 ** 30 = 1024 ** 3 =    1073741824
    - 'T' = 2 ** 40 = 1024 ** 4 = 1099511627776

The program is minimalistic as it has a minimal RAM (6 MB) and CPU footprint.

To stop the program press Ctrl-C.

Examples:

    $ minmon -l log3.log # write on stdout and on ~/.minmon/log3.log
