Statistical counters
Statistical counters in the NXLog language are specialized types used for aggregating and analyzing log data, providing various calculations. These counters enable detailed statistical analysis over specified intervals, helping you to understand log trends and patterns.
The following statistical counters are available:
- COUNT
-
Added values are aggregated, and the value of the counter is increased if only positive integers are added until the counter is destroyed or indefinitely if the counter has no expiry.
- COUNTMIN
-
This calculates the minimum value of the counter.
- COUNTMAX
-
This calculates the maximum value of the counter.
- AVG
-
This algorithm calculates the average over the specified interval.
- AVGMIN
-
This algorithm calculates the average over the specified interval, and the value of the counter is always the lowest which was ever calculated during the lifetime of the counter.
- AVGMAX
-
Like AVGMIN, but this returns the highest value calculated during the lifetime of the counter.
- RATE
-
This calculates the value over the specified interval. It can be used to calculate events per second (EPS) values.
- RATEMIN
-
This calculates the value over the specified interval, and returns the lowest rate calculated during the lifetime of the counter.
- RATEMAX
-
Like RATEMIN, but this returns the highest rate calculated during the lifetime of the counter.
- GRAD
-
This calculates the change in the rate of the counter over the specified interval, which is the gradient.
- GRADMIN
-
This calculates the gradient and returns the lowest gradient calculated during the lifetime of the counter.
- GRADMAX
-
Like GRADMIN, but this returns the highest gradient calculated during the lifetime of the counter.
