NUTSCAN(3) NUT Manual NUTSCAN(3)

NAME

nutscan - Network UPS Tools (NUT) device discovery library

DESCRIPTION

The Network UPS Tools (NUT) nutscan library provides the same discovery related features that are also offered by nut-scanner(8).
 
It allows to discover 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 needed 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 these functions return a list of devices found, using the nutscan_device_t structure. This one is described in nutscan_add_device_to_device(3).
 
Helper functions are also provided to output data using standard format:
 
•
 
nutscan_display_parsable(3) for parsable output,
 
•
 
nutscan_display_ups_conf(3) for ups.conf style.

ERROR HANDLING

There is currently no specific mechanism around error handling.
