How is the template cache file handled for NetflowV9?

[eksantrik]

I just need some clarification on a couple of items:

• How come there are no "flowset ID" and "length" fields in the template cache file? (Ref: https://www.ibm.com/support/knowledgecenter/en/SSCVHB_1.2.1/collector/cnpi_collector_template_flowset.html)
• Is there any limitation on the amount of templates that vflow keeps in the cache file at any given time?
• Are the specific templates updated when the template on a source device is changed? OR are they inserted as a new record?
• If you have more than 100 templates coming into vflow, are they all stored in the same cache file? Is there a limitation on the number of templates that vflow can keep? If there is a limit, how does it handle the cases when this limit is crossed?
• What is the ten digit ID at the beginning of the templates: "Templates": { "3011383114": { "Template": { "TemplateID": 1024, "FieldCount": 13, "FieldSpecifiers": [ { "ElementID": 8, "Length": 4.........

Thanks.
