# Final Aggregator Plugin
|
|
|
|
The final aggregator emits the last metric of a contiguous series. A
|
|
contiguous series is defined as a series which receives updates within the
|
|
time period in `series_timeout`. The contiguous series may be longer than the
|
|
time interval defined by `period`.
|
|
|
|
This is useful for getting the final value for data sources that produce
|
|
discrete time series such as procstat, cgroup, kubernetes etc.
|
|
|
|
When a series has not been updated within the time defined in
|
|
`series_timeout`, the last metric is emitted with the `_final` appended.
|
|
|
|
### Configuration
|
|
|
|
```toml
|
|
[[aggregators.final]]
|
|
## The period on which to flush & clear the aggregator.
|
|
period = "30s"
|
|
## If true, the original metric will be dropped by the
|
|
## aggregator and will not get sent to the output plugins.
|
|
drop_original = false
|
|
|
|
## The time that a series is not updated until considering it final.
|
|
series_timeout = "5m"
|
|
```
|
|
|
|
### Metrics
|
|
|
|
Measurement and tags are unchanged, fields are emitted with the suffix
|
|
`_final`.
|
|
|
|
