We recently deployed the new 10.7 CTG extension to WebSphere app server running on z/OS using the NoRedef agent.
Some apps recently reported clamps and on checking the agent logs we find very high number of log messages similar to the following:
[ERROR] [IntroscopeAgent.Agent] Attempted to create a metric with the invalid metric name "Backends|CTG_to_CICS_ECI_IPIC_Trace|tcp://myserver.com:3120|YSS2C00:Responses Per Interval".

Should the name formatter already have replaced the illegal ":" character in the metric name?
Is this a bug in the CTG extension?
Is the metric naming problem somehow contributing to the clamps?
