Suggestion: in the ups-log.py script, open a local debug logging file with <br>
handle "fd_log" in mode "append". Record every call of ups-log.py in "fd_log", <br>
whether valid or not. Does "some text" appear in "fd_log"? For the other calls <br>
of ups-log.py, does anything appear in "fd_log"?<br>
<br>
Roger<br>
<br>
For example:<br>
<br>
# Function open_log_file opens a file for logging<br>
# The file owner will be uid, with group gid, e.g. upsd:daemon<br>
# Returns file handle<br>
def open_log_file (logfile, uid, gid) :<br>
try :<br>
fd_log = open(logfile, 'a') # Opened for current user, re-open if user change<br>
os.chmod(logfile, 0o664)<br>
os.chown(logfile, uid, gid)<br>
return fd_log<br>
except :<br>
Your favourite error handling ...<br>

Philippe Andersson I think tried to respond on this thread but all I see is<br>
your corporate email signature?<br>
<br>
I did some more troubleshooting tonight. TL;DR at the end. First,<br>
confirmed that NOTIFYCMD is in fact firing. So I changed it to:<br>
NOTIFYCMD logger "NOTIFYCMD FIRED!"<br>
followed by:<br>
sudo service nut-client restart<br>
and that message does show up in /var/log/messages when I pull the plug on<br>
the ups, so something is happening.<br>
<br>
Next I tried changing the command to a bash script:<br>
NOTIFYCMD /etc/nut/call-ups-log.sh<br>
<br>
Inside that bash script, I just have this:<br>
<br>
#!/bin/sh<br>
logger "called call-ups-log.sh"<br>
/home/pi/Documents/scripts/ups-log.py "$*"<br>
<br>
"called call-ups-log.sh" shows up in /var/log/messages as expected, but the<br>
python script still isn't getting called. I thought maybe it was something<br>
to do with the directory Documents/scripts/ so I moved it to /etc/nut/ and<br>
reconfigured everything, same result. But at this point the bash script<br>
and python script are in the same directory with the same owner and<br>
permissions.<br>
<br>
TL;DR: I think at this point I've eliminated permissions problems, but<br>
there's something that is preventing NUT NOTIFYCMD from calling a python<br>
script properly. The python script I'm using is here, it's working fine<br>
when I call it from a command line:<br>
<a href="https://pastebin.com/AXi67sV6" rel="noreferrer" target="_blank">https://pastebin.com/AXi67sV6</a><br>
<br>
Thanks for all the help and sorry for the text brick!<br>
<br>
<br>
Moved call-ups-log.sh to Documents/scripts, and all of a sudden it's not<br>
working anymore either. Okay, so maybe it's the directory.<br>

The good news is that the NOTIFYCMD mechanism is working. This is beginning to <br>
look like a Python problem.<br>
