# Prometheus Remote Write source plugin
> Configure the Prometheus Remote Write source plugin in Chronosphere Telemetry Pipeline to ingest metrics for processing and routing.
export const entity_0 = "Prometheus Remote Write source plugin"
export const plugin_0 = "Prometheus Remote Write source plugin"
This information is for Chronosphere Telemetry Pipeline, which is a standalone product separate from Chronosphere Observability Platform.
The Prometheus Remote Write [source plugin](/ingest/pipeline/plugins/source-plugins)
(name: `prometheus_remote_write`) lets you ingest data from the
[Prometheus Remote-Write API](https://prometheus.io/docs/specs/remote_write_spec/)
into a telemetry pipeline.
This is a [push-based](/ingest/pipeline/plugins/source-plugins#push-based-and-pull-based-source-plugins) source plugin.
## 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.
### Required
| Name | Key | Description | Default |
| -------- | ------ | ---------------------------------------------------- | ------- |
| **Port** | `port` | Required. The port for the pipeline to receive data. | `8088` |
### Advanced
| Name | Key | Description | Default |
| ----------------------- | ------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------- |
| **Tag from URI** | `tag_from_uri` | Sets tag from URI. For example, v1\_metrics from /v1/metrics. | `false` |
| **URI** | `uri` | Sets the URI to receive Prometheus Remote Write metrics on. | `/api/prom/push` |
| **Chunk Size** | `buffer_chunk_size` | Sets the default [chunk](https://docs.fluentbit.io/manual/administration/buffering-and-storage#chunks) size for buffered data. If a single record exceeds this size, the plugin temporarily increases the chunk size up to the value of `buffer_max_size` to accommodate it. | `512K` |
| **Buffer Max Size** | `buffer_max_size` | Sets the maximum [chunk](https://docs.fluentbit.io/manual/administration/buffering-and-storage#chunks) size for buffered data. If a single record exceeds this size, the plugin drops that record. | `4M` |
| **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. 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. 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* |
### Security and TLS
| Name | Key | Description | Default |
| ------------------------------ | ---------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------- | ------- |
| **TLS** | `tls` | If `true`, enables TLS/SSL. If `false`, disables TLS/SSL. Accepted values: `true`, `false`. | `false` |
| **TLS Certificate Validation** | `tls.verify` | If `on`, and if `tls` is `true`, enables TLS/SSL certificate validation. If `off`, disables TLS/SSL certificate validation. Accepted values: `on`, `off`. | `on` |
| **TLS Debug Level** | `tls.debug` | Sets TLS debug verbosity level. Accepted values: `0` (No debug), `1` (Error), `2` (State change), `3` (Informational), `4` (Verbose). | `1` |
| **CA Certificate File Path** | `tls.ca_file` | Absolute path to CA certificate file. | *none* |
| **Certificate File Path** | `tls.crt_file` | Absolute path to certificate file. | *none* |
| **Private Key File Path** | `tls.key_file` | Absolute path to private key file. | *none* |
| **Private Key Path Password** | `tls.key_passwd` | Password for private key file. | *none* |
| **TLS SNI Hostname Extension** | `tls.vhost` | Hostname to be used for TLS SNI extension. | *none* |
