Hi Mario,

I tried the link you provided and it seems the error is not related to that. I checked further and it says that the sensor is either removed or not active. I am currently lost of the moment, anything you can provide me about the fix will be helpful.

Thanks

Hi Glenn

During Which CI discovery you are getting this?

In My system i see 213 Sensors (Paris Latest Patch).

If possible compare the sensors of all your 3 Instances.

Very Broad KB but you need to Identify which Sensor?

Hi Rahul,

During Which CI discovery you are getting this? "Im just doing a quick discovery for my MID server"

In My system i see 213 Sensors (Paris Latest Patch). "I have 219 sensors for my dev instance"

If possible compare the sensors of all your 3 Instances. "the count of sensors are just the same"

Very Broad KB but you need to Identify which Sensor? here is the error message after discovery "[code]Sensor error when processing <a href='ecc_queue.do?sys_id=172fa981db6e2410be7f684814961933'><u>Horizontal Pattern</u></a>: No sensors defined[/code]"
