Nagios plugin which checks json values from a given endpoint against argument
specified rules and determines the status and performance data for that
service

optional arguments:
  -h, --help            show this help message and exit
  -d, --debug           Debug mode.
  -s, --ssl             HTTPS mode.
  -H HOST, --host HOST  Host.
  -P PORT, --port PORT  TCP port
  -p PATH, --path PATH  Path.
  -t TIMEOUT, --timeout TIMEOUT
                        Connection timeout (seconds)
  -B AUTH, --basic-auth AUTH
                        Basic auth string "username:password"
  -D DATA, --data DATA  The http payload to send as a POST
  -f SEPARATOR, --field_separator SEPARATOR
                        Json Field separator, defaults to "." ; Select element
                        in an array with "(" ")"
  -w [KEY_THRESHOLD_WARNING [KEY_THRESHOLD_WARNING ...]], --warning [KEY_THRESHOLD_WARNING [KEY_THRESHOLD_WARNING ...]]
                        Warning threshold for these values
                        (key1[>alias],WarnRange key2[>alias],WarnRange).
                        WarnRange is in the format [@]start:end, more
                        information at nagios-plugins.org/doc/guidelines.html.
  -c [KEY_THRESHOLD_CRITICAL [KEY_THRESHOLD_CRITICAL ...]], --critical [KEY_THRESHOLD_CRITICAL [KEY_THRESHOLD_CRITICAL ...]]
                        Critical threshold for these values
                        (key1[>alias],CriticalRange
                        key2[>alias],CriticalRange. CriticalRange is in the
                        format [@]start:end, more information at nagios-
                        plugins.org/doc/guidelines.html.
  -e [KEY_LIST [KEY_LIST ...]], --key_exists [KEY_LIST [KEY_LIST ...]]
                        Checks existence of these keys to determine status.
                        Return warning if key is not present.
  -E [KEY_LIST_CRITICAL [KEY_LIST_CRITICAL ...]], --key_exists_critical [KEY_LIST_CRITICAL [KEY_LIST_CRITICAL ...]]
                        Same as -e but return critical if key is not present.
  -q [KEY_VALUE_LIST [KEY_VALUE_LIST ...]], --key_equals [KEY_VALUE_LIST [KEY_VALUE_LIST ...]]
                        Checks equality of these keys and values
                        (key[>alias],value key2,value2) to determine status.
                        Multiple key values can be delimited with colon
                        (key,value1:value2). Return warning if equality check
                        fails
  -Q [KEY_VALUE_LIST_CRITICAL [KEY_VALUE_LIST_CRITICAL ...]], --key_equals_critical [KEY_VALUE_LIST_CRITICAL [KEY_VALUE_LIST_CRITICAL ...]]
                        Same as -q but return critical if equality check
                        fails.
  -m [METRIC_LIST [METRIC_LIST ...]], --key_metric [METRIC_LIST [METRIC_LIST ...]]
                        Gathers the values of these keys (key[>alias],UnitOfMe
                        asure,WarnRange,CriticalRange,Min,Max) for Nagios
                        performance data. More information about Range format
                        and units of measure for nagios can be found at
                        nagios-plugins.org/doc/guidelines.html Additional
                        formats for this parameter are: (key[>alias]),
                        (key[>alias],UnitOfMeasure),
                        (key[>alias],UnitOfMeasure,WarnRange,CriticalRange).
