# feature-auto-instrumentation   Gathers telemetry data via automatic instrumentation The auto-instrumentation feature deploys Grafana Beyla to automatically instrument programs running on this cluster using eBPF. ## Testing This chart contains unit tests to verify the generated configuration. The hidden value `deployAsConfigMap` will render the generated configuration into a ConfigMap object. While this ConfigMap is not used during regular operation, you can use it to show the outcome of a given values file. The unit tests use this ConfigMap to create an object with the configuration that can be asserted against. To run the tests, use `helm test`. Be sure perform actual integration testing in a live environment in the main [k8s-monitoring](../..) chart. ## Maintainers | Name | Email | Url | | ---- | ------ | --- | | petewall | | | ## Source Code * ## Requirements | Repository | Name | Version | |------------|------|---------| | https://grafana.github.io/helm-charts | beyla | 1.7.3 | ## Values ### Beyla | Key | Type | Default | Description | |-----|------|---------|-------------| | beyla.config.data | object | `{"attributes":{"kubernetes":{"enable":true}},"internal_metrics":{"prometheus":{"path":"/internal/metrics"}},"prometheus_export":{"features":["application","network","application_service_graph","application_span"],"path":"/metrics"}}` | The configuration for Grafana Beyla Some sections will be set automatically, such as the cluster name. Others will be modified depending on the value of beyla.preset. | | beyla.extraDiscoveryRules | string | `""` | Rule blocks to be added to the discovery.relabel component for Beyla. These relabeling rules are applied pre-scrape against the targets from service discovery. Before the scrape, any remaining target labels that start with __ (i.e. __meta_kubernetes*) are dropped. ([docs](https://grafana.com/docs/alloy/latest/reference/components/discovery.relabel/#rule-block)) | | beyla.extraMetricProcessingRules | string | `""` | Rule blocks to be added to the prometheus.relabel component for Beyla. ([docs](https://grafana.com/docs/alloy/latest/reference/components/prometheus.relabel/#rule-block)) These relabeling rules are applied post-scrape against the metrics returned from the scraped target, no __meta* labels are present. | | beyla.labelMatchers | object | `{"app.kubernetes.io/name":"beyla"}` | Label matchers used to select the Beyla pods for scraping metrics. | | beyla.maxCacheSize | string | 100000 | Sets the max_cache_size for the prometheus.relabel component for Beyla. This should be at least 2x-5x your largest scrape target or samples appended rate. ([docs](https://grafana.com/docs/alloy/latest/reference/components/prometheus.relabel/#arguments)) Overrides metrics.maxCacheSize | | beyla.metricsTuning.excludeMetrics | list | `[]` | Metrics to drop. Can use regular expressions. | | beyla.metricsTuning.includeMetrics | list | `[]` | Metrics to keep. Can use regular expressions. | | beyla.preset | string | `"application"` | The configuration preset to use. Valid options are "application" or "network". | | beyla.scrapeInterval | string | 60s | How frequently to scrape metrics from Beyla. Overrides metrics.scrapeInterval | | beyla.service | object | `{"targetPort":9090}` | The port number for the Beyla service. | ### General settings | Key | Type | Default | Description | |-----|------|---------|-------------| | fullnameOverride | string | `""` | Full name override | | nameOverride | string | `""` | Name override | ### Global Settings | Key | Type | Default | Description | |-----|------|---------|-------------| | global.maxCacheSize | int | `100000` | Sets the max_cache_size for every prometheus.relabel component. ([docs](https://grafana.com/docs/alloy/latest/reference/components/prometheus.relabel/#arguments)) This should be at least 2x-5x your largest scrape target or samples appended rate. | | global.platform | string | `""` | The specific platform for this cluster. Will enable compatibility for some platforms. Supported options: (empty) or "openshift". | | global.scrapeInterval | string | `"60s"` | How frequently to scrape metrics. |
