# Mock Data source plugin

> Configure the Mock Data source plugin in Chronosphere Telemetry Pipeline to ingest logs for processing and routing.

export const entity_0 = "Mock Data source plugin"

export const plugin_0 = "Mock Data source plugin"

<Info>
  This information is for Chronosphere Telemetry Pipeline, which is a standalone product separate from Chronosphere Observability Platform.
</Info>

The Mock Data [source plugin](/ingest/pipeline/plugins/source-plugins)
(name: `dummy`) lets you input user-generated data into a telemetry pipeline.

Although this is a self-contained plugin that doesn't communicate with external
sources, it's still classified as a [pull-based](/ingest/pipeline/plugins/source-plugins#push-based-and-pull-based-source-plugins)
source plugin.

<Note>
  To use the Mock Data source plugin, you must create your own dataset and feed that
  data to the plugin. If you'd prefer to have Chronosphere Telemetry Pipeline generate
  simulated log data on your behalf, use the
  [Datagen](/ingest/pipeline/plugins/source-plugins/datagen) plugin instead.
</Note>

<Note>
  This plugin doesn't support duplicates of itself within the same pipeline.

## Supported telemetry types

The {plugin_0} for Chronosphere Telemetry Pipeline supports these telemetry types:

|                    Logs                    |             Metrics             |              Traces             |

## Configuration parameters

Use the parameters in this section to configure the {entity_0}. The
Telemetry Pipeline web interface uses the items in the **Name** column to
describe these parameters. [Pipeline configuration files](/ingest/pipeline/v2/configure/config-files)
use the items in the **Key** column as YAML keys.

| **Memory Buffer Limit**            | `mem_buf_limit`   | Sets a limit for how much buffered data the plugin can write to memory, which affects backpressure. This value must follow Fluent Bit's rules for [unit sizes](https://docs.fluentbit.io/manual/administration/configuring-fluent-bit#unit-sizes). If unspecified, no limit is enforced. <p />For v2 pipelines, this parameter affects only pipelines with the Deployment or DaemonSet [workload](/ingest/pipeline/v2/configure/kubernetes/workloads) type. To learn more, see the v2 [backpressure](/ingest/pipeline/v2/configure/backpressure) guide. <p />For v3 pipelines, this parameter is independent from the [OpenTelemetry `memory_limiter` and `batch` processors](/ingest/pipeline/v3#route-data-from-fluent-bit-to-opentelemetry). | *none*  |
