UPSLOG(8)                         NUT Manual                         UPSLOG(8)



NAME
       upslog - UPS status logger

SYNOPSIS
       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
       -h
           Display 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:

           %%
               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

       The default format string is:

           %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%

       -i interval
           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.
