Error in Unix-agent communication?

Help
1

Seems that between 31 Januari and 01 February the librenms.log started showings error for the devices where I’m polling BIND statistics.
The error:
Error in unix-agent module. Call to undefined method App\Models\Device::pollingTarget()

#0 /opt/librenms/vendor/laravel/framework/src/Illuminate/Support/Traits/ForwardsCalls.php(36): Illuminate\Database\Eloquent\Model::throwBadMethodCallException(‘pollingTarget’)

#1 /opt/librenms/vendor/laravel/framework/src/Illuminate/Database/Eloquent/Model.php(1618): Illuminate\Database\Eloquent\Model->forwardCallTo(Object(Illuminate\Database\Eloquent\Builder), ‘pollingTarget’, Array)

#2 /opt/librenms/vendor/laravel/framework/src/Illuminate/Database/Eloquent/Model.php(1630): Illuminate\Database\Eloquent\Model->__call(‘pollingTarget’, Array)

#3 /opt/librenms/includes/polling/unix-agent.inc.php(15): Illuminate\Database\Eloquent\Model::__callStatic(‘pollingTarget’, Array)

#4 /opt/librenms/includes/polling/functions.inc.php(315): include(’/opt/librenms/i…’)

#5 /opt/librenms/poller.php(174): poll_device(Array, false)

#6 {main}

code is up to date. no validation errors.

Any ideas ? TIA

Just tested… it’s on the librenms server that the error exists, because the unix-agent on the target responds on the telnet connection.

e.g.

telnet 6556

Tried to give composer access to online repo via a github token
(which is not stricly necessary) and saw:

php /opt/librenms/composer.phar outdated

GitHub API limit (60 calls/hr) is exhausted, could not fetch https://api.github.com/repos/librenms/StringBladeCompiler/contents/composer.json?ref=. Create a GitHub OAuth token to go over the API rate limit. You can also wait until 2020-02-04 21:21:02 for the rate limit to reset.

Head to Sign in to GitHub · GitHub<some_numbers>

to retrieve a token. It will be stored in “/home/librenms/.composer/auth.json” for future use by Composer.

in issue #11102 it says that the merge is blocked.
When does the code get available then ?

Juste updated code:

====================================

But bug fix hasn’t made it yet into. Same error.

@zoeloe : The fix need to be reviewed, tested, approved and merged. This takes some time as LibreNMS is a community project. But it will happen in the next hours/days.

12

@PipoCanaja : I see, the review process is more complex than I expected.
Thanks for explaining this.
If it helps, I’ve modded manually the file with the fix, and I’m seeing values and graphs again.
my 2 cents worth.

13

Not necessary so complex, but I am currently at work, like the other team members, and we do it on spare time. So step 1 is to have spare time :smiley:

looks like it’s working. I changed it manually on my server this morning.
