Team Center Experience Cards Showing "No Traffic" or "No Data"

Issue/Introduction

We noticed this morning that the experience cards are no longer showing data/traffic. We are still able to see metrics via Investigator (or drilling down to the vertices in Map view). We noticed in the logs that we started getting an Internal Server error:

Caused by: com.wily.introscope.spec.metric.BadlyFormedNameException: "Frontends|Apps| Web Application|URLs|" is not a legal Metric name

Cause

 Trouble handling the illegal metric name in the path. Some Frontend names ends with “|” and thus creating a bad metric name. In customer’s case its "Frontends|Apps|Booking Web Application|URLs|". “|” @ the end of URLs has caused this.

Environment

APM 10.7.0 SP 1

Resolution

Obtain the desktop fix in DE368014 or DE370152 and place on top of APM 10.7.0 SP1 .
This is now addressed in APM 10.7.0 HF11 and later.
