nutscan — Network UPS Tools (NUT) device discovery library


The Network UPS Tools (NUT) nutscan library provides the same discovery related features that are also offered by nut-scanner(8).

It enables the discovery of supported NUT devices (USB, SNMP, Eaton XML/HTTP and IPMI) and NUT servers (using Avahi, or the classic connection method).

Discovery Functions

First, include the required header file:

#include <nut-scan.h>

Then, to discover new devices, use the appropriate function:

· nutscan_scan_usb(3) for supported USB devices,

· nutscan_scan_snmp(3) for supported SNMP agents,

· nutscan_scan_xml_http(3) for Eaton Network Management Card,

· nutscan_scan_nut(3) for NUT servers (upsd), using the classic method,

· nutscan_scan_avahi(3) for NUT servers (upsd), using the mDNS (Avahi) method,

· nutscan_scan_ipmi(3) for supported IPMI PSU.

All of these functions return a list of devices found, using the nutscan_device_t structure. This structure is described in nutscan_add_device_to_device(3).

Helper functions are also provided to output data using standard formats:

· nutscan_display_parsable(3) for parsable output,

· nutscan_display_ups_conf(3) for ups.conf style.

Error Handling

There is currently no specific mechanism for error handling.
