Sending commands using nco_http

When using nco_http, commands are sent to the probe, in JSON format, using the HTTP POST method.

There are two groups of command:

Get commands for retrieving data from the agent
Set commands for setting data in the agent

The following sections show the format of each command in nco_http and include an example of each. The examples operate on the System group of objects in the standard SNMP MIB. This MIB resides in the internet management subtree of the SNMP object tree. In addition, there is information on messages that can appear in the log file to indicate success of the command or indicate a problem with the syntax of the command line.

The sections use the following conventions for the parameter values:
