Elastic Social Manual / Version 2401
Table Of ContentsThis section describes the configuration and usage of Counters in CoreMedia Elastic Social.
The following CounterServices are available in Elastic Social:
CounterService: for simple counters with a given name and value which can increment or decrement a value.HistogramCounterService: for counters which also contain a date. This is necessary if you want to determine a counter value for a certain time period, for instance the most commented articles in the last week.AverageCounterService: for counters which can increment and decrement two values, the total sum and the number of samples to calculate an arithmetic mean, for instance if you want to calculate the average rating. It handles counters with and without a date.
Counters are stored in the database [prefix]_[tenant]_counters. The following collections contain counter values:
| Name | Description |
|---|---|
| counters | Counters with aggregated value |
| histogram_counters | Histogram counters with date and sum |
| average_counters | Average counters with aggregated sum and quantity |
| average_histogram_counters | Average counters with date, sum and quantity |
Table 4.4. Counter collections
Each counter is stored aggregated with a value in the counters collection.
Each histogram counter is stored separately with sum and date in the histogram_counters
collection and aggregated with value in the counters collection.
Each average counter is stored separately with sum, quantity and date in the
average_histogram_counters collection and aggregated with sum and quantity in the
average_counters collection.
A sorted list for highest values for simple counters without a date can easily be calculated using a simple query. Lists which need to consider an average value or a certain time interval need to be aggregated using map and reduce jobs.
The following collections contain these aggregated sorted lists of counter values, for instance the most commented targets in a given time interval:
| Name | Description |
|---|---|
highest_average_counters
| The highest average counters without time limitation (infinity) |
highest_average_counters_[INTERVAL]
| The highest average counters for the given time interval for instance the last week ("LAST_WEEK") |
highest_histogram_counters_[INTERVAL]
| The highest histogram counters for the given time interval for instance the last week ("LAST_WEEK") |
Table 4.5. Aggregated counter collections
All aggregated counter lists are updated in given time intervals that are configurable
(counters.aggregation-interval-milliseconds[.interval], see
Table 3.37, “Counters Properties” in Deployment Manual).
Counters can also be refreshed manually using JMX, see Section 3.3.4, “Refresh counters”.
The following tables list the predefined counters in Elastic Social which you can access via the counter services.
