nut-upsd connection lost

I'm using nut-upsd image on a RPI4 for a tecnoware Era Plus 1100 and evything works fine except in the following cases: 1) in case I disconnect and reconnect the USB on RPI 2) UPS for some strange reason loses serial connection for a while

I both case the port changes (e.g. from /dev/bus/usb/00X/00Z to /dev/bus/usb/00Y/00W). In order to have always the same port I've created a rule so that the usb port is always mapped to /dev/myUPS and I've configured such port on my dockerfile:

  nut-upsd:
    container_name: nut-upsd
    image: instantlinux/nut-upsd
    volumes:
      - "/home/antonio/nut-upsd-pwd:/run/secrets/nut-upsd-password"
    environment:
    - "PORT=/dev/myUPS"
    - "NAME=tecnoware"
    - "DESCRIPTION=Technoware Era Plus 1100"
    - "DRIVER=blazer_usb"
    - "API_USER=master"
    network_mode: host
    privileged: true
    restart: always

Also with such configuration I lose the connection to UPS in both cases I reported above... of course the first case is not real, meaning I used for testing... of course I've checked that when the USB is reconnected and/or the UPS re-establish the connection, symbolik link to usb port is updated correctly.

Thanks for support

Hello, I am using your docker container that worked well til the latest update or so. I am guessing is the same as the author, I did not want to hijack his tread.

version docker tag used: latest = 2.8.1-r0

  nut-server:
    image: instantlinux/nut-upsd:latest
    container_name: nut-server
    restart: unless-stopped
    privileged: true
    environment:
      SERIAL: xxxxxxxxxxxx

What is the output of this command (part of Dockerfile's HEALTHCHECK) directive, when this happens with your UPS model, from a docker exec -it <id> sh shell? (Make sure $NAME env is set to ups, which is default for latest image).

echo $NAME
upsc $NAME@localhost:3493 2>&1

An important assumption is that the upsc command output will include the word stale, and cause the container to restart: but evidently the output is vendor-specific, so the pattern to be matched needs updating. Please help out by providing the output for the Cyber Power.

Hello,

Here is the required information:

used: latest = 2.8.1-r0

/ # echo $NAME
CP1500EPFCLCD
/ # upsc $CP1500EPFCLCD@localhost:3493 2>&1
upscli_splitname: got empty upsname string
Error: invalid UPS definition.
Required format: upsname[@hostname[:port]]

I want to mention that nut-upsd:2.8.0-r4 works ok and has the following output:

/ # echo $NAME
CP1500EPFCLCD
/ # upsc $CP1500EPFCLCD@localhost:3493 2>&1
Init SSL without certificate database
Error: Unknown UPS

The command output I want to see is

upsc $NAME@localhost:3493 2>&1

which expands the variable $NAME, not expanding a non-existent variable $CP1500EPFCLCD, below is incorrect:

upsc $CP1500EPFCLCD@localhost:3493 2>&1

Someone reported a bug with there being two $$ characters in the healthcheck: this was corrected in the 2.8.1-r0 tag; I've yet to fully confirm whether the fix (PR #140) is proper. To confirm, you can do docker history instantlinux/nut-upsd:<tag> for that tag or others that are present on your host.

Does the symptom still appear when you comment out the NAME: CP1500EPFCLCD environment variable in docker-compose.yml?

Let me know if anything else is needed, I'll help no problem.

@hellcry37 @poliant @KC-inDomus please invoke docker pull instantlinux/nut-upsd:latest (or tag 2.8.1-r0 to update if you use this tag) and confirm the two changes I've made. The first change is to ensure that the container takes itself down for restart if data goes stale, and the second is to add the MAXAGE parameter. If you're using Cyberpower model, add this to your docker-compose file in the nut-server -> environment section:

    environment:
      ...
      MAXAGE: 25

Other users: if this causes unwanted restarts for other UPS units, please make me aware of it here or in a new issue. This latest change is a bit risky so I might have to add protective logic for the default case.

Does this fix the issue or just restarts when "Data stale" is detected? If the issue is not fixed that means container will restart in a loop at some point (that will not help)

what is that MAXAGE: 25 do?

If the issue is caused by the UPS unit taking longer than 15 seconds, the default value of MAXAGE, to report its data: it will be fixed. Please change that parameter and see if the container stays running without restarts. Googling for this problem is inconclusive.

will change it now and come back

Til now it seem to work ok.

However we have a warning I dont know if is of any importance:

WARNING: Needed to fix group access to filesystem socket of this driver, but failed; run the driver with more debugging to see how exactly.

I'll come back tomorrow to tell you if this worked as it should. Thank you for all your hard work and your patience!

Ahhh too soon it just failed again container restarted:

So atm it will restart in a loop. Work, fail, restart, work, fail, restart, ...

In the container under directory /etc/nut, you'll find the config files. Copy those off into a directory on your local host (docker cp <container> /etc/nut/* ~/my-test-dir or something like that) and then add a mount definition for that path:

  services:
    app:
      ...
      volumes:
      - ~/my-test-dir:/etc/nut/local

Check that the value of MAXAGE in upsd.conf is set to your desired value (if the entrypoint script didn't work, it'll still be defaulted to 15 instead of overridden to 25). Once you're running with files in the local override path, then you can experiment with values such as POLLFREQ and DEADTIME which I don't try to manage with the current input variables (which work fine for APC and some other models, but now we're trying to get CyberPower working).

How often is the restart happening, after the first hour or so of running? If changes to some of those other variables have any effect, can you get it to stay stable for longer than several hours at a time? I'll be happy to add support for more variables once this is confirmed.

I did not see a point in modify so much the docker to make a volume and add files there, I did all this in the container to get data for you.

docker exec -it nut-server sh / # cd /etc/nut/ /etc/nut # cat upsd.conf

# =======================================================================
# MAXAGE <seconds>
MAXAGE 25

So from here we conclude the MAXAGE var works fine.

Container restarts onece per 1h - 6h is not a well defined time tbh. In HA it dropped on: 16:41 19:39 20:32 23:40 05:09

As you can see not a well defined pattern :)

switched to local config files mode! What should I test next?

I can't think of what specific changes might address the problem. Searching online, I found a few discussions about the CyberPower stale-data problem posted over the past several years:

Those, along with comments found in the distributed config files under /etc/nut, should help point you to the solutions others have found. Once you can get it stable 24hrs, post the resulting values here. Thanks!

Whatever I do still fails, I'll just use the old one and move on with my life

OK fair enough. Hopefully the restart logic is now stable enough to use, and that others will post their successful parameter values for this model or others that don't behave the same way as APC.

Hello @instantlinux, I've been facing the stale-data issue with two CyberPower UPS. The MAXAGE parameter does not appear to be working for me when creating the container. The upsd.conf file only includes: LISTEN 0.0.0.0 after the commented sections from NUT.

I am mounting a custom ups.conf and upsmon.conf file to configure both UPS devices in one container, which has been working fine aside from the stale-data issue.

By creating and mounting a upsd.conf with this:

MAXAGE 60
LISTEN 0.0.0.0

Both of the UPS devices have been running for 36 hours continuously without issue. I may try to lower the MAXAGE value defined in the upsd.conf file, but I'm not familiar enough with shell to know why the if block in the entrypoint.sh for MAXAGE appears to be ignored.

Here's the relevant details of my compose file in case this is helpful.

nut-upsd:
    image: instantlinux/nut-upsd
    container_name: nut-upsd
    volumes:
      - /opt/nut:/etc/nut/local
    devices:
      - /dev/bus/usb
    environment:
      API_PASSWORD: "XXXXXXXXX"
      MAXAGE: 60
    restart: unless-stopped

I'd be happy to test this out further with you to confirm the MAXAGE variable is resolving the issue.
