NAME¶
upsc - example lightweight UPS clientSYNOPSIS¶
upsc -l | -L [host]DESCRIPTION¶
upsc is provided as a quick way to poll the status of a UPS server. It can be used inside shell scripts and other programs that need UPS data but don’t want to include the full interface.OPTIONS¶
-l hostList all UPS names configured at host,
one name per line. The hostname defaults to "localhost". You may
optionally add a colon and a port number.
-L host
As above, list all UPS names configured at
host, including their description provided by the remote upsd(8) from
ups.conf(5). The hostname defaults to "localhost". You may
optionally add a colon and a port number to override the default port.
-c ups
Lists each client connected on ups, one
name per line.
ups
Display the status of that UPS. The format for
this option is upsname[@hostname[:port]]. The default hostname is
"localhost".
variable
Display the value of this variable only. By
default, upsc retrieves the list of variables from the server and then
displays the value for each. This may be useful in shell scripts to save an
additional pipe into grep.
EXAMPLES¶
To list all variables on an UPS named "myups" on a host called "mybox", with upsd(8) running on port 1234:$ upsc myups@mybox:1234 battery.charge: 100.0 battery.voltage: 13.9 battery.voltage.nominal: 13.6 . . .
$ upsc -L apc: Back-UPS 500 ppro2: Patriot Pro II
$ for UPS in `upsc -l mybox:1234`; do upsc $UPS ups.status done
$ upsc -c myups 127.0.0.1 ::1 192.168.1.2
DIAGNOSTICS¶
upsc will either print a list of UPS names, a list of all supported variables and their values on the UPS, or an error message. If you receive an error, make sure you have specified a valid UPS on the command line, that upsd(8) is really running on the other host and that no firewalls are blocking you.HISTORY¶
Earlier versions of this program used the upsfetch library and UDP sockets to talk to upsd. This version of upsc uses the new upsclient library, which only talks TCP. This is why upsct no longer exists.SEE ALSO¶
