NAME

apcaccess —

retrieve status information from apcupsd(8)

SYNOPSIS

apcaccess [-f <config-file>] [-h <host>[:<port>]] [-p <parameter-name>] [-u] [<command>] [<host>[:<port>]]

DESCRIPTION

apcaccess is a program which prints out the complete status of most American Power Conversion Corp. (APC) UPSes provided you have the apcupsd(8) daemon installed, properly configured and running. It can access status information from any APC UPS attached to the localhost or attached to any computer on the network which is running apcuspd in NIS mode.

The command line options are:

-f: configuration file of apcupsd (default is usually /etc/apcupsd/apcupsd.conf)
-h: hostname and port of apcupsd to communicate with. The default hostname and port are obtained from the configuration file.
-p: Report only the value of the named parameter instead of all parameters and values.
-u: Remove units field for easier parsing by scripts.
<command>: An optional command, unless a hostname is also being specified. The only implemented command is status Shorthand for status localhost:3551. This produces a full printout of the available status information for the associated UPS.
<host>: An optional hostname which may be a bare machine name, fully qualified domain name or IP address.
:<port>: An optional port number where a hostname argument has been specified. The default is 3551, the official port number assigned by IANA for the apcupsd NIS server. The default hostname and port are obtained from the configuration file.

apcaccess uses apcupsd's inbuilt Network Information Server (NIS) -- no relation to Sun's NIS/YP service -- to obtain the current status information from the UPS on the local or remote computer. It is therefore necessary to have the following configuration directives:

NETSERVER on
NISPORT 3551

in the /etc/apcupsd/apcupsd.conf configuration file so that the Network Information Server will be accessible. Firewall rules for appropriate network access may also be needed.

STATUS REPORT FORMAT

The status report output format is simple ASCII. Generally there is a single piece of information on each line of output. The content varies based on the model of UPS being used and, in some cases, the firmware version.

EXAMPLES

Set out below is a sample of the status output which may be generated for the specified UPS models.

CABLE: : Cable type specified in the configuration file
MODEL: : UPS model derived from UPS information
UPSMODE: : Mode in which UPS is operating
STARTTIME: : Date and time apcupsd was started
STATUS: : UPS status. One or more of the following (space-separated): CAL TRIM BOOST ONLINE ONBATT OVERLOAD LOWBATT REPLACEBATT NOBATT SLAVE SLAVEDOWN
