Gathers telemetry data via automatic instrumentation
10+
11+
The auto-instrumentation feature deploys Grafana Beyla to automatically instrument programs running on this cluster
12+
using eBPF.
13+
14+
## Testing
15+
16+
This chart contains unit tests to verify the generated configuration. A hidden value, `deployAsConfigMap`, will render
17+
the generated configuration into a ConfigMap object. This ConfigMap is not used during regular operation, but it is
18+
useful for showing the outcome of a given values file.
19+
20+
The unit tests use this to create an object with the configuration that can be asserted against. To run the tests, use
21+
`helm test`.
22+
23+
Actual integration testing in a live environment should be done in the main [k8s-monitoring](../k8s-monitoring) chart.

| Key | Type | Default | Description |
49+
|-----|------|---------|-------------|
50+
| 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)) |
51+
| 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. |
52+
| beyla.labelMatchers | object | `{"app.kubernetes.io/name":"beyla"}` | Label matchers used to select the Beyla pods for scraping metrics. |
53+
| 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 |
54+
| beyla.metricsTuning.excludeMetrics | list | `[]` | Metrics to drop. Can use regular expressions. |
55+
| beyla.metricsTuning.includeMetrics | list | `[]` | Metrics to keep. Can use regular expressions. |
56+
| beyla.preset | string | `"application"` | The configuration preset to use. Valid options are "application" or "network". |
57+
| beyla.scrapeInterval | string | 60s | How frequently to scrape metrics from Beyla. Overrides metrics.scrapeInterval |
58+
| beyla.service | object | `{"targetPort":9090}` | The port number for the Beyla service. |

71+
| 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. |
72+
| global.scrapeInterval | string | `"60s"` | How frequently to scrape metrics. |
