If, for some reasons, you have to change the MetricCollectionDefinition.xml for some agents, make sure, you do not use any XML Pretty Printer (like Notepad++ with XML add-on). According my tests, the SAPControlWSCollector interprets added \n and \r (by the pretty printer), although these characters are outside the CDATA area.

You’ll notice gray metrics in technical monitoring as well as following errors within the diagnostics agent’s protocol, it a MetricCollectionDefinition.xml was formated using an XML Pretty Printer and uploaded to a Diagnostics Agent.
