--- title: "Set up meta-monitoring | Grafana Agent documentation" description: "Learn how to set up meta-monitoring for Grafana Agent Flow" --- # Set up meta-monitoring You can configure Grafana Agent Flow to collect its own telemetry and forward it to the backend of your choosing. This topic describes how to collect and forward Grafana Agent Flow’s metrics, logs and traces data. ## Components and configuration blocks used in this topic - [prometheus.exporter.self](/docs/agent/v0.43/flow/reference/components/prometheus.exporter.self/) - [prometheus.scrape](/docs/agent/v0.43/flow/reference/components/prometheus.scrape/) - [logging](/docs/agent/v0.43/flow/reference/config-blocks/logging/) - [tracing](/docs/agent/v0.43/flow/reference/config-blocks/tracing/) ## Before you begin - Identify where to send Grafana Agent Flow’s telemetry data. - Be familiar with the concept of [Components](/docs/agent/v0.43/flow/concepts/components/) in Grafana Agent Flow. ## Meta-monitoring metrics Grafana Agent Flow exposes its internal metrics using the Prometheus exposition format. In this task, you will use the [prometheus.exporter.self](/docs/agent/v0.43/flow/reference/components/prometheus.exporter.self/) and [prometheus.scrape](/docs/agent/v0.43/flow/reference/components/prometheus.scrape/) components to scrape Grafana Agent Flow’s internal metrics and forward it to compatible Grafana Agent Flow components. 1. Add the following `prometheus.exporter.self` component to your configuration. The component accepts no arguments. Alloy ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy ```alloy prometheus.exporter.self "" { } ``` 2. Add the following `prometheus.scrape` component to your configuration file. Alloy ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy ```alloy prometheus.scrape "" { targets = prometheus.exporter..default.targets forward_to = [] } ``` Replace the following: - *``* : The label for the component such as `default` or `metamonitoring`. The label must be unique across all `prometheus.exporter.self` components in the same configuration file. - *``* : The label for the scrape component such as `default`. The label must be unique across all `prometheus.scrape` components in the same configuration file. - *``* : A comma-delimited list of component receivers to forward metrics to. For example, to send to an existing remote write component, use `prometheus.remote_write.WRITE_LABEL.receiver`. Similarly, to send data to an existing relabeling component, use `prometheus.relabel.PROCESS_LABEL.receiver`. To use data in the OTLP format, you can send data to an existing converter component, like `otelcol.receiver.prometheus.OTEL.receiver`. The following example demonstrates configuring a possible sequence of components. Alloy ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy ```alloy prometheus.exporter.self "default" { } prometheus.scrape "metamonitoring" { targets = prometheus.exporter.self.default.targets forward_to = [prometheus.remote_write.default.receiver] } prometheus.remote_write "default" { endpoint { url = "http://mimir:9009/api/v1/push" } } ``` ## Meta-monitoring logs The [logging](/docs/agent/v0.43/flow/reference/config-blocks/logging/) block defines the logging behavior of Grafana Agent Flow. In this task, you will use the [logging](/docs/agent/v0.43/flow/reference/config-blocks/logging/) block to forward Grafana Agent Flow’s logs to a compatible component. The block is specified without a label and can only be provided once per configuration file. 1. Add the following `logging` configuration block to the top level of your configuration file. Alloy ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy ```alloy logging { level = "" format = "" write_to = [] } ``` Replace the following: - *``* : The log level to use for Grafana Agent Flow’s logs. If the attribute isn’t set, it defaults to `info`. - *``* : The log format to use for Grafana Agent Flow’s logs. If the attribute isn’t set, it defaults to `logfmt`. - *``* : A comma-delimited list of component receivers to forward logs to. For example, to send to an existing processing component, use `loki.process.PROCESS_LABEL.receiver`. Similarly, to send data to an existing relabeling component, use `loki.relabel.PROCESS_LABEL.receiver`. To use data in the OTLP format, you can send data to an existing converter component, like `otelcol.receiver.loki.OTEL.receiver`. The following example demonstrates configuring the logging block and sending to a compatible component. Alloy ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy ```alloy logging { level = "warn" format = "json" write_to = [loki.write.default.receiver] } loki.write "default" { endpoint { url = "http://loki:3100/loki/api/v1/push" } } ``` ## Meta-monitoring traces The [tracing](/docs/agent/v0.43/flow/reference/config-blocks/tracing/) block defines the tracing behavior of Grafana Agent Flow. In this task you will use the [tracing](/docs/agent/v0.43/flow/reference/config-blocks/tracing/) block to forward Grafana Agent Flow internal traces to a compatible component. The block is specified without a label and can only be provided once per configuration file. 1. Add the following `tracing` configuration block to the top level of your configuration file. Alloy ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy ```alloy tracing { sampling_fraction = write_to = [] } ``` Replace the following: - *``* : The fraction of traces to keep. If the attribute isn’t set, it defaults to `0.1`. - *``* : A comma-delimited list of component receivers to forward traces to. For example, to send to an existing OpenTelemetry exporter component use `otelcol.exporter.otlp.EXPORT_LABEL.input`. The following example demonstrates configuring the tracing block and sending to a compatible component. Alloy ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy ```alloy tracing { sampling_fraction = 0.1 write_to = [otelcol.exporter.otlp.default.input] } otelcol.exporter.otlp "default" { client { endpoint = "tempo:4317" } } ```
