NAME¶
upslog - UPS status loggerSYNOPSIS¶
upslog -h upslog [OPTIONS]DESCRIPTION¶
upslog is a daemon that will poll a UPS at periodic intervals, fetch the variables that interest you, format them, and write them to a file. The default format string includes variables that are supported by many common UPS models. See the description below to make your own.OPTIONS¶
-hDisplay the help message.
-f format
Monitor the UPS using this format string. Be sure to
enclose format in quotes so your shell doesn’t split it up.
Valid escapes within this string are:
%%
The default format string is:
Insert a single "%"
%TIME format%
Insert the time with strftime formatting
%ETIME%
Insert the number of seconds, ala time_t. This is now a
10 digit number.
%HOST%
insert the local hostname
%UPSHOST%
insert the host of the UPS being monitored
%PID%
insert the pid of upslog
%VAR varname%
insert the value of variable varname
%TIME @Y@m@d @H@M@S% %VAR battery.charge% %VAR input.voltage% %VAR ups.load% [%VAR ups.status%] %VAR ups.temperature% %VAR input.frequency%
Wait this many seconds between polls. This defaults to 30
seconds.
If you require tighter timing, you should write your own logger using the
upsclient(3) library.
-l logfile
Store the results in this file.
You can use "-" for stdout, but upslog will remain in the
foreground.
-s ups
Monitor this UPS. The format for this option is
upsname[@hostname[:port]]. The default hostname is
"localhost".
-u username
If started as root, upsmon will setuid(2) to the
user id associated with username for security.
If username is not defined, it will use the value that was compiled into
the program. This defaults to "nobody", which is less than
ideal.
SERVICE DELAYS¶
The interval value is merely the number given to sleep(3) after running through the format string. Therefore, a query will actually take slightly longer than the interval, depending on the speed of your system.LOG ROTATION¶
upslog writes its PID to upslog.pid, and will reopen the log file if you send it a SIGHUP. This allows it to keep running when the log is rotated by an external program.SEE ALSO¶
