UPS service (nut): only works after manual restart

I am closing it @Zamana, C. R. for now. Please refer to NUT and file an issue with them. If you have further reason to believe that we can improve some aspect of this, please feel free to comment here and we can re-open this. Thank you

Hi!

Thanks for reply.

Ok, I'll check again the issue you refer too. We have more data now, at least.

Regarding the "maxretry": Fatal error: 'maxretry' is not a valid variable name for this driver.

Thanks.
Regards.

auxiliary parameters can be added via UI ( services -> UPS -> auxiliary params ups.conf )

I think it is fair to assume this is a driver issue on NUT part.
See this https://alioth-lists.debian.net/pipermail/nut-upsuser/2015-August/009810.html.
And it also relates to the github issue comment i highlighted above in one of my comments.

I think you should post an issue with them. However as the problem seems to go away after a restart of solis driver ( service nut restart ), you can try setting "maxretry" option as an auxiliary parameter for ups.conf and set it to 2 or 3 perhaps and see if the issue persists ? ( https://networkupstools.org/docs/man/ups.conf.html - just for reference )

Looking forward to hearing from you!

Hello Ahmed.

I performed the procedure right now, but the conclusion is unclear to me. Here is my results so far:

I reached the step 6) with everything working, then I rebooted.

After the system started up, I received 2 e-mails from the system at the same time (08:49):
COMMBAD - ups

Then I ran the commands after the step 9):

root@freenas[~]# service nut_upsmon onestatus
nut_upsmon is running as pid 3147.
root@freenas[~]# /usr/local/libexec/nut/solis -DDD -a ups
Network UPS Tools - Microsol Solis UPS driver 0.65 (2.7.4)
   0.000000 debug level is '3'
   0.000537 getbaseinfo: sending CMD_UPSCONT and ENDCHAR to sync
   1.128473 getbaseinfo: received -1 bytes from ser_get_buf_len()
   1.128495 Solis not detected! aborting ...

Then I restarted the Netdata service, and the UPS service appeared in the monitoring screen.

After some minutes, at 08:58, I received another e-mail from the system, this time:
NOCOMM - ups

Then I ran the 2 commands again, and the last one kept running until I interrupted with CTRL-C:

root@freenas[~]# /usr/local/libexec/nut/solis -DDD -a ups

Right now (09:33), I didn't received any other e-mail, UPS is still showing in Netdata, and everything seems fine.
