Bulk Statistics
Bulk statistics are the statistics that are collected periodically and written to a set of CSV files. These statistics can be used by external analytic processes and/or network management systems. Bulk stats allows you to combine different KPIs into a unified query that fetches the custom statistical data. For the complete list of PCF KPIs, see Statistics and KPI Reference.
The SMI component handles the collection of the bulk stats from the nodes and PCF consumes these stats. The bulk stats are generated for the following components:
-
Container: Includes the raw and rate of the change statistics.
-
Pod: Includes the raw and rate of the change statistics.
-
System: Consists of the system level KPIs.
Note | The container and Pod statistics contain the predefined infrastructure outputs such as CPU and memory. You can also customize the query to fetch specific outputs as per your requirement. |
There are two types of bulk statistics:
-
Gauge - A snapshot value that shows the statistic at that reporting moment (for example, the number of current PDP contexts, simultaneous Active EPS Bearers). Gauge statistics can increment or decrement continuously.
-
Counter - A historic value that shows the statistic that accumulated over time (for example, the total number of CSR requests received). Counter values can only increment except in two cases: rollover, where a counter exceeds its maximum value and rolls over to zero, and reset, where a counter is manually reset to zero.
