||
| ## Description | ||
|
|
||
| The interval processor (`intervalprocessor`) aggregates metrics and periodically forwards the latest values to the next component in the pipeline. The processor supports aggregating the following metric types: | ||
|
|
||
| * Monotonically increasing, cumulative sums | ||
| * Monotonically increasing, cumulative histograms | ||
| * Monotonically increasing, cumulative exponential histograms | ||
|
|
||
| The following metric types will *not* be aggregated, and will instead be passed, unchanged, to the next component in the pipeline: | ||
|
|
||
| * All delta metrics | ||
| * Non-monotonically increasing sums | ||
| * Gauges | ||
| * Summaries | ||
|
|
||
| ## Configuration | ||
|
|
||
| The following settings can be optionally configured: | ||
|
|
||
| - `max_staleness`: The total time a state entry will live past the time it was last seen. Set to 0 to retain state indefinitely. Default: 0 |
