[Nut-upsuser] Another New User Question - Notify Script Not Running

    <font size="-1">Hello and thanks in advance for any
help/tips. I am
      still new to nut but thanks to help here, I have managed to get my
      Ubuntu (chrooted on Android) to run both nut-server and nut-client
      without obvious complaints. So now I am trying to move on to
      getting the desired results when the UPS goes and stays on battery
      for at least 20 seconds. After looking here
<a class="moz-txt-link-rfc2396E"
href="https://networkupstools.org/docs/user-manual.chunked/ar01s07.html"><https://networkupstools.org/docs/user-manual.chunked/ar01s07.html></a>
      I am taking the simple approach - where my own script. Salient
      lines from the upsmon.conf are:<br>
      <br>
      NOTIFYCMD? /home/android/nutShutdown.sh<br>
      NOTIFYMSG? ONBATT? "USP %s on battery"<br>
      NOTIFYFLAG? ONBATT? EXEC<br>
      <br>
      The script file is rwx for all. So I do not think this is a
      permission issue (but certainly could be wrong).<br>
      <br>
      When I pull the battery nothing at all seems to happen. From an
      ssh terminal into the nut machine I can see the status go from O:
      to OB using upsc. But the script does not seem to get run.<br>
      <br>
      If I stop the nut-client service and instead run:<br>
      <br>
      ? /sbin/upsmon -DD<br>
      <br>
      (just from my logged in, non-priv user) I see the following:<br>

      After line </font><font
size="-1">50.046388?</font>I am seeing
    output from my script. So at least in this scenario, things appear
    to be working.<br>
    <br>
    Yet with service nut-client start'ed this doesn't seem to happen.
    Using:<br>
    <br>
    ??? ps -ef | grep nut<br>
    <br>
    I see entries for the blazer_usb driver, /sbin/upsd, and
    sbin/upsmon. They are all running as user:<br>
    <br>
    ? nut<br>
    <br>
    So I immediately thought to check permissions on the script file
    and, as said above, they are rwx all. So I doubt this is the
    problem.<br>
    <br>
    Any thoughts/comments?<br>
    <br>
    Cheers<br>

Perhaps before plunging into upsmon debugging, and debugging your own custom 
NOTIFYCMD script, you could get the basic notifications of upsmon working using 
more complete NOTIFYFLAG and NOTIFYMSG declarations covering all situations. You
will then have a clearer view in the log of what is happening.  Why don't
you
have the SYSLOG option on the NOTIFYFLAG ONBATT declaration?

Can you call the nutShutdown.sh script from the command line as the user 
running upsmon?

If you need a custom Shutdown Plan, then why not use upssched?

I would also suggest increasing the log output of your script to identify and 
present more clearly what is happening in the script, for example by including 
the UPS status and charge. This will help you debug the script.

[Nut-upsuser] Another New User Question - Notify Script Not Running

Roger,

Thanks for the idea to add additional items to the notifyflag. That 
proved the monitor was indeed working as expected and led me to find 
that my script had myriad issues when run under the nut user. All 
remedied now.

As I progress, I may well end up migrating to the upssched. As a newbie 
I was simply following the documented "simple" way described here 
<https://networkupstools.org/docs/user-manual.chunked/ar01s07.html>.

Thanks to all!
