Supporting more granular statistics/bulkstats on APN (up to 2,000 APNs are supported) has an impact on system
performance and this occurs for bulkstats. Statistics need to be obtained at regular intervals for a few minutes. Each of
these retrievals can lead to gigabytes of information to be gathered and consolidated. Due to this issue, a
restricted/controlled usage of granular bulkstats is introduced. The operator can enable which APN to collect granular
statistics using the configuration. In those granular statistics, it is possible to decide which particular statistics to collect.

Previous Behavior: In general, the current bulkstats APN configuration gathers the bulkstat data for all of the APNs;
there is no option to restrict gathering of bulkstats for selective APN(s).

New Behavior: A new CLI is introduced to selectively enable an APN candidate list for the new bulkstat schema
“apn-expansion”. The eGTP-C cause code bulkstats will be collected for those APN(s) which are configured through
this CLI only.

Customer Impact: This feature allows operators to collect more granular GTP-C statistics on a per-APN and per-QCI
level to monitor certain KPIs based on these statistics.
