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. Polls are not instantaneous, so they will slip back as the program runs. If you require tighter timing, you should write your own logger using the upsclient 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].

-u username
    If started as root, upsmon will setuid(2) to the user id associated with username for security. If it 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() 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.
