Sensor error when processing Horizontal Pattern: No sensors defined (Discovery Log)

Sunny45 · ‎03-11-2022

Team,

We recently got new instance and have all plugins for discovery installed. I have a first MID server installed pointing to this instance.

When I ran the discovery to discover the MID server using same MID server, I am getting below error message in discovery log. I believe we can discover the MID server using same MID without any credentials.(correct me if I am wrong). The OS on the server which I am discovering is Windows Server 2019 Standard

"Sensor error when processing Horizontal Pattern: No sensors defined"

Please advise if I am missing any sensor. I am seeing that there is no sensor defined in Horizontal discovery.(last snap)

For no sensors defined,

There is kb article for that.

Every active probe looks for a corresponding sensor to process the data that is collected by the probe. The No Sensors Defined message indicates that the corresponding sensor for the probe is missing or inactive.

Its very weird, if there is no customisation is not made by you.

Need to see input mesage of ecc queue,

Which step pattern throws the error

Thanks Anshu,

But I believe this migration is not needed if we are on Kingston or newer version. We are on Rome.

Hi Anshu,

Yeah pattern is launched but it errors out as I shown above in my snap shot. In Discovery log it says no sensor defined.

Here it is again.
