Sensor error when processing Horizontal Pattern

[Glenn11]

I am finding this issue in the discovery log? Any help would be great!

Sensor error when processing Horizontal Pattern: No sensors defined

[Pooja Chugwani]

Hi Glenn,

I believe discovery is triggering some pattern to discover your MID server. Please check in discovery sensors if "Horizontal Discovery Sensor " is present in your instance or not.

If not, then you can import the xml from some other instance, else if you provide me the exact version, I can share the XML file with you.

After importing the XML, please run discovery again. That should resolve your issue.

Hi Pooja,

I checked the sensors table and im not sure if this is it, when i try searching it on the name search  no results. I am using the quebec version. if you can provide me the CML that would be great.

Hi Glenn,

Please import the attached xml file and run discovery again

Hi Glenn,

If importing the XML file, resolved your issue then mark this answer as solved, so that other users facing this issue can also find this solution.

Thanks,

Pooja

Hi Pooja,

I have set up Azure event based discovery. When I create  a new subnet in the Azure subscription, an event gets create in service now cloud events table. Cloud discovery is also triggered, but it stuck in the processing stage and shows the below warning and error message:
