Hi guys, can you please let me know why when I run the autodiscovery on a group device/device with standard template, i find duplicate sensor? Is it possible to avoid existing sensor?

Hello psechi,
thank you for your inquiry.

If you're seeing duplicate sensors while using standard templates, the most likely explanation is that you're mixing up sensors that have been created manually and by the auto-discovery. If that is the case, I encourage you to delete all existing sensors on the relevant device and re-run the auto-discovery to make sure that all existing sensors were created by the auto-discovery.

Further auto-discoveries following this "first" discovery should not create any more duplicates. Should this continue to happen after doing the above, we'll need to know what precise sensor type is affected (leading to duplicates) to investigate this further.

Best Regards,

Hello,

thanks for your reply.

All existing sensors have been created by the Automatic device identification (standard), but when i run auto-discovery to update and add new sensors, then i see duplicates.

You can find below an example for understanding:

I look forward for your reply.

Thanks Pietro S.

Hello Pietro,
thank you for your reply.

Please check the settings tab of two sensors for the same interface. For example Gi0/0. In the settings tab of both sensors there will be a Interface Number value in the settings.

Please let me know the content of this field for both interfaces (original and duplicate). It should be something like:

6:ge0/0/0

Hi,

same Interface number for both of them:

original2:interfaccia lan interna
duplicate2:interfaccia lan interna

Thanks, Pietro

Hello Pietro,
thank you for your reply.

Could it be that you're mixing up Custom and Standard device templates? This could also explain what is happening.

The auto-discovery won't be able to avoid duplicates if you're mixing up custom and standard templates. When you want to re-discover new sensors on a schedule, you should always use the very same set of templates.

Please delete all sensors and perform a new auto-discovery. Then, re-run the discovery and confirm that no duplicates were created.

Best Regards,
