Discovery Sensors from the Pattern Designer plugin are missing in some New York and Orlando instances, inc. Horizontal Discovery Sensor, HTTP - Classify - Known Error

Discovery Sensors from the Pattern Designer plugin are missing in some New York and Orlando instances, inc. Horizontal Discovery Sensor, HTTP - Classify Description 4 Discovery Sensors from the Pattern Designer plugin are missing in some instances:

Horizontal Discovery Sensor https:// .service-now.com/discovery_sensor.do?sys_id=2f32f7899f230200fe2ab0aec32e706a

Pattern Debugger Sensor https:// .service-now.com/discovery_sensor.do?sys_id=dd580613ff113100ab8fffffffffff3b

HTTP - Classify https:// .service-now.com/discovery_sensor.do?sys_id=09a2616c9ff30300a114d0aec32e70c7

DNSLookupProbeHandler https:// .service-now.com/discovery_sensor.do?sys_id=71ba03a57f503100ed1c3b19befa910c

This has been seen in New York and Orlando instances. The related Probes from the same plugin are present.

This causes the following errors in the Discovery Log:

Sensor error when processing Horizontal Pattern: No sensors defined Sensor error when processing HTTP - Classify: No sensors defined Steps to Reproduce

Steps to reproduce on demand in a real-world scenario on a new instance have not yet been determined. This does not happen on all instances.

This can be reproduced if the Pattern Designer plugin has been enabled before the Discovery plugin, but that should not happen on a normal instance due to dependencies.

Workaround This problem is currently under review. You can contact ServiceNow Technical Support or subscribe to this Known Error article by clicking the Subscribe button at the top right of this form to be notified when more information will become available.

To resolve the issue once you have it, the "Pattern Designer" [com.snc.pattern.designer] plugin will need Re-activating to repair the plugin and put back the missing files. This plugin is not listed to admin users, and so please open a Case in HI for Technical Support to do this for you.
