CAdvisorResource

class

cAdvisor — per-container CPU/Memory/Network metrics (local-only, needs the Docker socket).

Felder

GrafanaBuilderExtensions

static class

Fluent API for a composable Grafana observability stack. Start with AddGrafana, then attach components — every component call also provisions the matching Grafana datasource, wires start ordering and groups the container under Grafana in the Aspire dashboard. Call order does not matter: cross-component configs are generated at application start.

GrafanaDatasource

class

A Grafana datasource that gets written into the generated provisioning YAML. The stack auto-creates datasources for Prometheus / Loki / Tempo / Postgres; use WithDatasource for anything else Grafana supports (MySQL, MSSQL, Elasticsearch, InfluxDB, …) — Type takes the Grafana datasource type id, JsonData/SecureJsonData map 1:1 to the provisioning schema.

Konstruktoren

• GrafanaDatasource()

Eigenschaften

• Access : string { get; set; }
  Access mode. proxy (server-side, default) or direct.
• Editable : bool { get; set; }
  Whether the datasource may be edited in the Grafana UI. Default false (provisioning owns it).
• IsDefault : bool { get; set; }
  Marks this datasource as Grafana's default.
• JsonData : Dictionary<string, object> { get; }
  Non-secret settings, serialized under jsonData:. Values may be scalars, nested Dictionary2` (string → object) or lists.
• Name : string { get; set; }
  Display name in Grafana. Required.
• SecureJsonData : Dictionary<string, object> { get; }
  Secret settings, serialized under secureJsonData:. Prefer env-var references like ${MY_VAR} over literals — the generated YAML lands on disk, Grafana expands the variable on load.
• Type : string { get; set; }
  Grafana datasource type id, e.g. prometheus, loki, tempo, postgres, mysql. Required.
• Uid : string { get; set; }
  Stable uid used by dashboards to reference this datasource. Defaults to a slug of Name.
• Url : string { get; set; }
  Target URL, e.g. http://prometheus:9090 or my-db:5432. Required.
• User : string { get; set; }
  Login user for datasources that need one (e.g. SQL databases).

GrafanaResource

class

Grafana dashboards UI. Acts as the hub of the observability stack: every component added via WithPrometheus / WithLoki / WithTempo / WithOtelCollector / … registers itself here and is auto-provisioned as a Grafana datasource. Configs are generated at application start (not at builder time), so the With* calls can come in any order.

Nextended.Aspire.Hosting.Observability

ObservabilityStackExtensions

static class

One-call observability stack for an Aspire application: • Grafana — dashboards UI (acts as the parent resource that all other monitoring containers nest under in the Aspire dashboard) • Prometheus — metrics scraping • postgres_exporter — Postgres internals as Prometheus metrics • Loki — log aggregation • Promtail — Docker container log shipper → Loki (local-only) • cAdvisor — per-container metrics (local-only) • Tempo — traces backend (opt-in) • OTel-Collector — OTLP receiver / fan-out (opt-in) This is a thin composition over the fluent building blocks in GrafanaBuilderExtensions — use those directly for piecemeal setups. YAML configs are GENERATED at startup from the actual resource hostnames and bind-mounted into the containers; no hardcoded hostnames in the file tree. Publish-mode (azd up): Promtail and cAdvisor are auto-skipped because they rely on the host's Docker socket, which Azure Container Apps doesn't expose. The rest of the stack deploys cleanly.

ObservabilityStackOptions

class

Options for AddObservabilityStack — the one-call, batteries-included way to get the full stack. For piecemeal composition use the fluent AddGrafana().WithPrometheus()… API from GrafanaBuilderExtensions; this options class drives exactly those building blocks.

Konstruktoren

• ObservabilityStackOptions()

Eigenschaften

• AspireDashboardOtlpEndpoint : string { get; set; }
  Aspire-dashboard OTLP endpoint that the OTel-Collector mirrors traces to. Default points at host.docker.internal:18889 — Aspire 13's standard local-dev port. Set to "" to disable the mirror exporter.
• CAdvisorImage : string { get; set; }
• CAdvisorImageTag : string { get; set; }
• ConfigRootPath : string { get; set; }
  Working directory where the stack writes its generated YAML configs and (by default) reads dashboard JSONs from. Required. The stack creates a .generated/ sub-folder here at runtime for the Prometheus / Loki / Promtail / Tempo / OTel-Collector / Grafana-Provisioning YAMLs.
• DashboardsPath : string { get; set; }
  Folder containing the Grafana dashboard JSON files (one file = one dashboard, auto-loaded by Grafana's provisioning). When null, defaults to {ConfigRootPath}/grafana/dashboards. Set explicitly if dashboards live outside the config tree.
• GrafanaAdminPassword : string { get; set; }
  Admin password used when GrafanaAnonymousAdmin is false. Should come from a secret in production scenarios.
• GrafanaAdminUser : string { get; set; }
• GrafanaAnonymousAdmin : bool { get; set; }
  When true (default), Grafana is started with anonymous Admin access — no login form. Convenient for local dev. Set false for shared/deployed setups and supply GrafanaAdminUser/GrafanaAdminPassword.
• GrafanaDashboardsFolder : string { get; set; }
  Grafana folder name under which auto-provisioned dashboards appear in the sidebar. Default "Application". Change to e.g. your app's name to brand the experience without touching dashboard JSON files.
• GrafanaImage : string { get; set; }
• GrafanaImageTag : string { get; set; }
• IncludeCAdvisor : bool { get; set; }
  cAdvisor — per-container CPU / Memory / Network metrics scraped from the Docker socket.
• IncludeGrafana : bool { get; set; }
• IncludeLoki : bool { get; set; }
• IncludeOtelCollector : bool { get; set; }

• OtelCollectorImage : string { get; set; }
• OtelCollectorImageTag : string { get; set; }
• PostgresExporter : PostgresExporterOptions { get; set; }
  Postgres-Exporter config. When null, no exporter container is added — useful if the consuming app doesn't use Postgres or already has metrics from elsewhere.
• PostgresExporterImage : string { get; set; }
• PostgresExporterImageTag : string { get; set; }
• PrometheusImage : string { get; set; }
• PrometheusImageTag : string { get; set; }

  Grafana retention for Prometheus (--storage.tsdb.retention.time). Default 15 days.
• PromtailImage : string { get; set; }
• PromtailImageTag : string { get; set; }
• ResourceNamePrefix : string { get; set; }
  Name prefix used for every Aspire resource the stack creates. Final names look like {ResourceNamePrefix}-prometheus, {ResourceNamePrefix}-grafana, etc. Defaults to "monitoring". Set to "" to keep bare names.
• TempoImage : string { get; set; }
• TempoImageTag : string { get; set; }
