genddx - Generates SNMP discovery instructions file for devdiscover


torrus genddx --host=HOSTNAME | --hostfile=HOSTFILENAME \ [options...]


genddx generates the SNMP discovery instructions file, which may be later used as input for the devdiscover utility to produce the corresponding Torrus XML configuration file. The hostname(s) of router(s) to be included in SNMP discovery must be specified either using the --host (for a single router) or --hostfile option. In the latter case the file HOSTFILENAME must contain a space-separated list of router hostnames. Hostnames may have the form host:devname where devname is a symbolic device name.

This utility is designed to be used only once, in order to generate the discovery XML canvas, for further manual editing. It generates only basic set of parameters, and there are much more of those that you may use to customize the discovery process.

See torrus_ttproclist(1) for a more flexible and complex DDX generator.
