NAME

       catalog_query - query records from the catalog server

SYNOPSIS

       catalog_query  [--where [expr]] [--catalog [host]] [-d [flag]] [-o [file]] [-O [size]] [-t
       [timeout]] [-h]

DESCRIPTION

       catalog_query is a tool that queries the catalog server for running services.  The  output
       can  be filtered by an arbitrary expression, and displayed in raw JSON form, or in tabular
       form. This tool is handy for querying custom record types not handled by other tools.

        --debug-file=<file>
               Send debug output to this file.

        --debug-rotate-max=<bytes>
               Rotate debug file once it reaches this size.

        --timeout=<seconds>
