XMLRPC call count chart from logs

This utility is used for analyzing calls distribution from the /var/log/rhn/rhn_server_xmlrpc.log files (including already rotated) what XML-RPC calls are happening per what period.

Source code: https://github.com/isbm/spacewalk-power-toys/blob/master/rpcmap.py

Usage:

rpcmap <mode> [options]

Modes:
    YYYY/MM/DD
        A valid day in the log, e.g. 2015/02/22 etc.

    --all
        Use all available dates in the log.

    --show
        List all available periods in the log.

Options:
    --use-all-logs
        Read all logs, including already compressed (rotated)

    --call=...
        A string that would match an XML-RPC call.

Result example:
