DESCRIPTION
mfscli is a commandline counterpart to MooseFS's CGI interface. All the information available in CGI (except for graphs) can be obtained via CLI using different "monitoring options"

OPTIONS

-h  print help message

-p  force plain text format on tty devices

-n  do not resolve ip addresses (default when output device is not tty)

-s separator
    field separator to use in plain text format on tty devices (forces -p)

-2  force 256-color terminal color codes

-8  force 8-color terminal color codes

-H master_host
    master address (default: mfsmaster)

-P master_port
    master client port (default: 9421)

-f 0..3
    set frame charset to be displayed as table frames in ttymode;

    0   simple ascii frames '+','-','|' (default)

    1   thick unicode frames

    2   thin unicode frames

    3   double unicode frames (dos style)

-o order_id
    sort data by column specified by 'order id' (depends on data set)

-r  reverse sort order

-m mode_id
    show data specified by 'mode id' (depends on data set)

-i id
    sessionid for -SOF or inode for -SAL

-a count
    how many chart entries should be shown for master

-b chart_data_columns
    define chart columns for master; prefix with '+' for raw data, prefix with 'ip:[port:]' for server choice

-c count
    how many chart entries should be shown for chunkserver

-d chart_data_columns
    define chart columns for chunkserver; prefix with '+' for raw data, prefix with 'ip:[port:]' for server choice

-SLD
    show label descriptions

-SLS
    show label sets

-SOF
    show only open files

-SAL
    show only acquired locks

-SMO
    show operation counters

-SQU
    show quota info

-SMC
    show master charts data

-SCC
