[Nut-upsuser] Early shutdowns and 2.6.5-1 package for Windows

[Denis Serov]

Hello Frederic!

>> upssched.conf
>> CMDSCRIPT "cmd.exe -C C:\\NUT\\1.cmd"

> I guess it's /C (not -C).

That is my misprint, slash is presented in original config file ;)

>> 1. NOTIFYCMD parameter is not specified NUT doesn’t start UPSSCHED 
>> tool (as I remember, Linux version do it by default).

> upssched is called by upsmon when a NOTIFYFLAG set to EXEC happens. It is not started by NUT service (even on Linux).

I thought about "NUT" as product, certainly, UPSMON executes UPSSCHED =) But my original worry was wrong, Linux version does not start UPSSCHED as default tool too (if NOTIFYCMD parameter is not specified). Sorry for misconception.

Well, I have meant something else. I sent a screenshot to you. You will find a lot of records which has been created by 2.6.0-1 version. Non-existing PIPEFN property was just a test to raise an error. Version 2.6.5-1 does not write to Windows Event Log anything except notifications about starting/stopping service/upsd/upsmon. That is not useful for troubleshooting.

I have very good news: the early shutdowns are working properly. Only one instance of UPSSCHED (for my configuration) is started and stopped, no errors like "read confirmation failed, trying again read confirmation failed" and CMDSCRIPT is executed. Here is UPSMON output:
  15.153257     do_notify: ntype 0x0005 (COMMBAD)

Excellent!

Thank you very much,
