Hi,
 
There is Session ID existing in Serviceability API. It's okay that session id is required in PerfmonPort Service, such as perfmonOpenSession, perfmonAddCounter. Session id helps receive session-based data.
 
But, what is the purpose of including Session ID in soap header for RisPort SOAP Service(selectCmDevice)?  I can receive response without including session ID.
 

<soap:Header>
<tns:AstHeader id="id1">
<SessionId xsi:type="xsd:string">SessionId</SessionId>
</tns:AstHeader>
</soap:Header>


Thanks in advance.
