hi-
i'm using version 2.4.1, courtesy of debian testing, and noticed that
in the web interface, the image for the battery voltage bar graph
wasn't displaying. the other images (change, input, output, load)
seem to be fine. the browser reports "500 internal server error", and
apache reports "Premature end of script headers: upsimage.cgi,
referer: https://graphs.ltn.lvc.com/cgi-bin/nut/upsstats.cgi?host=u...@localhost
"
upsc seems to also be working as expected, and reports a value for
battery voltage:
>upsc u...@localhost battery.voltage
55.00
i have 5 of these upses in total (smart-ups 1500 xlm monitored via
snmp) which all exhibit the same behavior.
how can i further troubleshoot this?
You could try running upsimage.cgi manually, maybe you'll get a useful
error message.
good idea, thanks. i can't seem to figure out how though. running the
program without any arguments produces output that seems to perhaps be
the beginnings of a png image, which would make sense, but it appears to
be incomplete. i've tried a few approaches to passing arguments from
the shell, but none seem to have an impact on the output.
some additional information - i've since added another smart-ups 1500
(not xlm), connected via usb to this same server, and it draws the
voltage graph without incident.
