The identifier is unique in the sense that it increments each time a WS statistics operation block is instantiated in memory. This is against startup, so no restart domain or disabling/enabling of statistics will address this. It is a 32-bit field so it will cap out and roll over if it reaches the maximum identifier.
The identifiers will change if:
- You change/update the WSDL within the web service proxy
- You restart the device
The unique identifier is to address an SNMP issue where SNMP would not poll all the status provider fields, only the first identifier. They had to assure a unique ID was given to each entry.
You would be best served by tracking the service endpoint, port type and operation fields. The identifier will not be guaranteed to be the same, only that it will be unique.
