Re: [Apcupsd-users] [PATCH] Conf: new SELFTESTGRACEPERIOD option to prevent self test shutdowns

Hi!

Maybe I've missed something, but I'm unable to find anything (which could 
just mean the messages ended in SPAM folder aigain :D) in the list, so you 
have likely not discussed this before here, correct? So the problem is, as I
understand the comments, the UPS starts self testing when it already has 
somewhat discharged accumuators, which results in LOWBATT signal, starting 
the procedure of apcupsd shutting the machine down, right?

That once again appears to me like trying to solve something much later what
should have been solved before actually buying anything. This series is 
known for decades as not having the HW AND SW (or rather, FW) equipment for 
what you would have expected of high-end hardware, despite APCs pricing and 
marketing could be somewhat overstating the actual position of this device 
in their product portfolio. Not that the CPU inside would not be able to 
handle that, but because APC (Schneider) made it so. I am quite possitive 
that Smart-UPS series clearly does not show such stupid behaviour, as being 
their business/entry-level-mission-critical piece of HW, it is an etalon (in
the means of "standard") of quality. So, amongst others, the self-test 
function clearly has condition to start only at 100% charge, when anything 
happens, the tests stops immediatelly and the device starts indicating 
problem (=showing REPLACE BATTERY and making noise every 10 minutes or so), 
also the unit measures same parameters as in self-testing during EACH power 
outtage, and generaly it is "smarter" (=better HW equipped and better 
programmed).

In short, ppl often come here in hopes of solving problems, they would never
have to be dealing with, haven't they chosen inferior, cheaped-out product 
in the first place. I can see from the address that you work in one of the 
hospitals, so I know well how shopping works in such instituions, when the 
first, second and third top criterias are price only. On the other hand, 
there are much better possibilities in terms of shopping for "critical" 
equipment in hospitals than at, say, state/public operated universities or 
hotels (=imagine 10times worse possibilities than you have in your 
organisation).

I mean, yeah, having such patch is great, I intend this rant more like a 
warning for ppl to do their research beforehand, and especially definitelly 
do NOT buy inferior devices in hopes that you can mitigate the problems 
later on the OS or the user side in general. Which is exactly what many ppl 
will do anyways after (if) Ted implements this :D UPS should be, in my view,
highly autonomous devices, correctly reporting either its operating states, 
or controlling conencted device directly for it to (when it has to) shut 
down gracefully, without any secondary damage.

Předmět: [Apcupsd-users] [PATCH] Conf: new SELFTESTGRACEPERIOD option to 
prevent self test shutdowns
"Hello, 

attached is the patch that hopefully resolves my struggles with 
Back-UPS RS 1500 LCD (849.H1 .I USB FW:H1) vs. apcupsd. 

I will keep an eye on whether it indeed helps me (no idea if 
I can speed automatic self test cadence up in any way with this 
device), but thought I might solicit feedback on this preliminary 
patch in the interim. Also, it's up there for any use under 
the same terms as the original project. 

I've read up a bit on the upleasant state of activity in the upstream, 
but should there be any interest in collective massaging of this 
patch so that it could be merged "once there is a good time", 
I am all ears. I am not subsribed to the list (not sure the message 
will make it through filters/moderation, please CC in possible 
responses to the list), but from what I gathered, Ted might be 
the best erson to talk with nowadays. 

It is also possible I am doing something wrong with this device, 
but I much rather be able to show that empirically, the commit 
indeed is of some usefulness (self test inflicted shutdowns no 
longer occur) ... I shall report on this progress after I gain 
some data points/confidence. 

Last but not least, maybe a problem akin to this was already 
discussed here? If so, can you point those threads to me, 
please? 

Thanks
