## Overview

## Configuration

```yaml theme={null}
processors:
    deltatocumulative:
        # how long until a series not receiving new samples is removed
        [ max_stale: <duration> | default = 5m ]
 
        # upper limit of streams to track. new streams exceeding this limit
        # will be dropped
        [ max_streams: <int> | default = 9223372036854775807 (max int) ]

```

There is no further configuration required. All delta samples are converted to cumulative.

## Troubleshooting

When [Telemetry is
enabled](https://opentelemetry.io/docs/collector/configuration/#telemetry), this component exports [several metrics](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/processor/deltatocumulativeprocessor/documentation.md).

## Configuration

### config.yaml (testdata)

```yaml theme={null}
deltatocumulative/all:
  max_stale: 1m
  max_streams: 10
deltatocumulative/set-valid-max_stale:
  max_stale: 2m
deltatocumulative/set-valid-max_streams:
  max_streams: 20
```

### config.yaml (testdata)

```yaml theme={null}
max_streams: 10
```
