Hi,after ignoring this for too long (see [1]), I'm still struggling how to shut down servers fed by two independent UPS systems. Both are connected to NUT via the snmp-ups driver with mibs "huawei" and "netvision".
However, I fear both do not feature the LB warning via ups.status.We can shut down all less important servers (conencted to a single UPS) via upssched and a 30s timer after OB, but I still struggle hard to arrive at a working schema how to shut down more important servers based on remaining battery charge/projected run time and/or low batt warning.
Looking at clients/upsmon.c I think, without the flag ST_LOWBATT set for ups->status, MINSUPPLY will never truly be considered a usable threshold and thus I'm left with a machine which would not shutdown.
Thus, what would e the best way forward here?* Try to patch the server to synthesize LB there? If so, any suggestion how to do this?
* Try to patch upsmon.c's is_ups_critical method to also include extra criteria, e.g. remaining run time/battery charge?
* Keep nut unpatched but use our own NOTIFYCMD or CMDSCRIPT to pull the values from the server and implement our logic there?
* Another way, I've overlooked? Cheers and thanks a ton in advance for suggestions. Carsten[1] Message-ID: <f794644f-e3b8-3557-da63-bd19d88a7...@aei.mpg.de> from 2022-12-05
