Help

Device type is not setting normally, I can set it manually, and if I run Discovery from Capture Debug Information it will set, but normally discovery, or from cli do not seem to set device type

Discovery

Poller

./poller.php -h HOSTNAME -r -f -d

Gives deprecated error, instead I ran

lnms device:poll -vvv HOSTNAME

This problem is present at least from 22th November. This is the time I saw it for the first time.

It doesn’t matter if I try to add device from web gui or from cli. Result is the same - device is added but no type is set. Tested on Mikrotik RouterOS devices.

Interesting is when I run

lnms device:discover

It does set the device type

6

I’m seeing exactly the same thing - when running ./discovery.php or the cron discovery it does not populate the device type but running lnms device:discover does work

@murrant device type setting looks to have been removed from discovery.php with this: Modern discovery by murrant · Pull Request #17813 · librenms/librenms · GitHub

Any reason or can we restore it?

8

I don’t think I removed it, probably only moved it.

Yes, it was moved outside the os module because it had to.
We have two options:

  1. restore the check into discovery.php somehow (it can’t be in the core module)
  2. stop using discovery.php and use lnms device:discover

Sorry I didn’t mean it was moved when it wasn’t supposed to, more that it was no longer where it used to be hence type no longer gets discovered.

Ideally we’d do #2 if it can be done quickly and safely.
