Сначала быстро найду существующие `exporter`/`collector`/`ServiceMonitor` паттерны и где они лежат, затем прочитаю несколько репрезентативных chart/app файлов, чтобы сравнить структуру `Deployment`, `Service`, annotations и values.

**Exploring YAML editing**

I need to consider if I should read the yamllint rules, especially since the user mentioned using it for editing YAML. While it's not directly relevant, I could mention observing the YAML structure to keep things concise. I should ensure to use absolute paths in the final version and maybe cite code blocks with file and line numbers. It’s important to explore the repo structure and use Glob for files like Chart.yaml and Application YAML, looking for components like exporter, collector, and ServiceMonitor.


text: Появились явные кандидаты: `common/kube-blender-exporter`, `common/prometheus-openstack-exporter`, `common/observability/flant/vmware-exporter` и рядом `common/trivy-operator`. Сейчас сравню их chart/template/value-структуру и посмотрю, как они подключаются к мониторингу.

**Reading deployment details**

I'm focusing on understanding key files, especially around kube-blender-exporter and its deployment, possibly with a Custom Resource Definition (CRD). I plan to check various files like Chart, deployment, and cluster-specific values. I'll also look into the trivy operator, especially for metrics insights. I'm considering where to add a collector, whether under common/trivy-operator or as a separate exporter. The pattern seems to suggest internal exporters go under common/ instead of apps. I’ll need to inspect for cluster-specific deployments too.


text:
В репо видно два разных мониторинговых паттерна: старый Deckhouse scrape через `prometheus.deckhouse.io/*` annotations и более “vanilla” `ServiceMonitor` в новых chart’ах вроде `trivy-operator`. Ещё проверю, включают ли `ServiceMonitor` реальными values, и есть ли готовые namespace/values-конвенции для shared `common/*` компонентов.

**Investigating app references**

It seems that my searches didn't really find any app references; perhaps the repository itself is focused on charts rather than Argo Applications. I’m considering looking up the app-of-apps pattern and checking the source path to common chart directories. I might use a tool for path searches and check if there's a folder structure like clusters/ or apps/. It's possible that there aren't explicit Argo Application manifests in the same directory, but I could suggest adding a common section since it would be shared across clusters, especially with per-cluster specific values.


text:
**Searching for examples**

I’m thinking that I need to find more examples related to the restic-backups exporter pattern. I'll search for "custom-target" since it could be relevant, particularly regarding the internal collector/exporter sidecar concept. It seems worthwhile to inspect the exporter template, too, as that might give me insights. There's a lot to unpack here, and I want to make sure I'm covering all the bases!


text:
Есть полезная repo-конвенция: как минимум `common/nat-node-exporter/README.md` прямо говорит, что ArgoCD применяет chart “для каждого кластера индивидуально” по имени файла в `values/`. Проверю ещё 1-2 похожих shared chart’а, чтобы рекомендация для нового `trivy` collector была не по одному примеру.

**Inspecting Argo values**

I need to look into the nat-node-exporter values or chart to understand the Argo values pattern and its location. Searching the README might provide valuable insights since Argo applies configurations based on filenames in the values directory. That sounds promising! I should also consider examining the common/nat-node-exporter chart or the related templates for further details. Let me dive in to inspect those elements and support the recommended pattern!


text: I'm thinking about using code blocks with start:end:path to effectively illustrate a pattern. This way, the information can be organized in a clear visual format. When I finalize my output, I might even include bullet points for easier readability. It seems like a good approach to help the user grasp the concept more intuitively. Let's see how this comes together and make sure it's as helpful as possible!

**Exploring app locations**

I need to check on the absence of trivy service annotations and whether they can be customized. It might not be essential to search for `app-of-apps`, but I'm wondering where such apps are typically stored. We might find them in directories like `common/` for shared charts or `common/observability/...` for vendor-related components. I could reference `apps/blackbox` as an exception for internal exporters. I think I should quickly inspect charts or templates to understand better!

## Findings

Самые близкие существующие паттерны для маленького internal exporter/collector я вижу в `common/*`, а не в `apps/*`.

- `/home/ruslanpi/Documents/repos/lmru--devops--argocd-apps/common/kube-blender-exporter`
  - Похоже на лучший референс для нового custom exporter.
  - Один `Deployment` + один `Service`.
  - Метрики публикуются через Deckhouse annotations на `Service`: `prometheus.deckhouse.io/custom-target`, `port`, `path`, `allow-unready-pod`, `sample-limit`.
  - Values layout: плоский `values/<cluster>.yaml`, по имени файла видно cluster-scoped rollout.
- `/home/ruslanpi/Documents/repos/lmru--devops--argocd-apps/common/prometheus-openstack-exporter`
  - Тоже standalone shared chart.
  - Есть `Deployment`, `Service`, `RBAC`, `alerts`, `grafana`.
  - Scrape pattern проще: `prometheus.deckhouse.io/custom-target` + named port `http-metrics`, без отдельного `ServiceMonitor`.
  - Values layout: `app.name`, `app.namespace`, `app.image`, `resources` в per-cluster values.
- `/home/ruslanpi/Documents/repos/lmru--devops--argocd-apps/common/observability/flant/vmware-exporter`
  - Очень похожий exporter pattern: `Deployment` + headless `Service`, Deckhouse scrape label/annotation, per-cluster secrets/host в values.
  - Хороший пример для exporter, которому нужны внешние креды.
- `/home/ruslanpi/Documents/repos/lmru--devops--argocd-apps/common/restic-backups`
  - Здесь exporter встроен как отдельный `Deployment` внутри более крупного chart’а.
  - Метрики обнаруживаются через pod label `prometheus.deckhouse.io/custom-target`.
  - Это скорее secondary pattern, если collector хочется держать внутри уже существующего chart’а.
- `/home/ruslanpi/Documents/repos/lmru--devops--argocd-apps/common/trivy-operator`
  - Уже есть свои metrics endpoint’ы.
  - Есть `Service` и готовый `ServiceMonitor` template.
  - Но в checked values используется Deckhouse scrape pattern на pod’ах; включенного `ServiceMonitor` для `trivy-operator` я не нашел.

## Key Patterns

`Deployment` + `Service` с Deckhouse scrape annotations:

```36:53:/home/ruslanpi/Documents/repos/lmru--devops--argocd-apps/common/kube-blender-exporter/templates/deployment-exporter.yaml
apiVersion: v1
kind: Service
metadata:
  name: {{ first (pluck .Values.global.env .Values.kube_blender_exporter) | default .Values.kube_blender_exporter._default }}-service
  namespace: {{ .Values.globals.namespace }}
  labels:
    prometheus.deckhouse.io/custom-target: {{ first (pluck .Values.global.env .Values.kube_blender_exporter) | default .Values.kube_blender_exporter._default }}
  annotations:
    prometheus.deckhouse.io/port: {{ $.Values.port | quote }}
    prometheus.deckhouse.io/path: "/metrics"
    prometheus.deckhouse.io/allow-unready-pod: "true"
    prometheus.deckhouse.io/sample-limit: {{ $.Values.limit | default 10000 | quote }}
spec:
  selector:
    app: {{ first (pluck .Values.global.env .Values.kube_blender_exporter) | default .Values.kube_blender_exporter._default }}
  ports:
    - protocol: TCP
      port: {{ .Values.port }}
```

`ServiceMonitor` как дополнительный, но не основной repo-wide pattern:

```1:33:/home/ruslanpi/Documents/repos/lmru--devops--argocd-apps/common/trivy-operator/prod/templates/monitor/servicemonitor.yaml
{{- if and (eq .Values.serviceMonitor.enabled true) (.Capabilities.APIVersions.Has "monitoring.coreos.com/v1") }}
apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
  name: {{ include "trivy-operator.fullname" . }}
  namespace: {{ .Values.serviceMonitor.namespace | default (include "trivy-operator.namespace" . ) }}
spec:
  selector:
    matchLabels: {{- include "trivy-operator.selectorLabels" . | nindent 6 }}
  endpoints:
  - honorLabels: {{ .Values.serviceMonitor.honorLabels }}
    port: metrics
    scheme: http
{{- end }}
```

## Values Layout

- Для small shared exporters чаще всего: `Chart.yaml` + `templates/*.yaml` + `values/<cluster>.yaml`
  - Примеры: `/home/ruslanpi/Documents/repos/lmru--devops--argocd-apps/common/kube-blender-exporter`
  - `/home/ruslanpi/Documents/repos/lmru--devops--argocd-apps/common/prometheus-openstack-exporter`
- Для более сложных или env-specific chart’ов:
  - `prod/` и `stage/` отдельно, плюс `values/values-global.yaml` и cluster overrides
  - Пример: `/home/ruslanpi/Documents/repos/lmru--devops--argocd-apps/common/trivy-operator`
- Для observability collectors под стек мониторинга:
  - `common/observability/lm/<collector>/values/stage/<cluster>/values.yaml` и `.../prod/...`
  - Пример: `/home/ruslanpi/Documents/repos/lmru--devops--argocd-apps/common/observability/lm/opentelemetry-collector`

## Recommended Place

Рекомендовал бы добавить новый Trivy CRD collector как отдельный shared chart в:

- `/home/ruslanpi/Documents/repos/lmru--devops--argocd-apps/common/trivy-crd-collector`

И брать паттерн в таком порядке:

1. Структура chart как у `kube-blender-exporter` или `prometheus-openstack-exporter`: отдельный `Deployment`, `Service`, при необходимости `RBAC`.
2. Scrape по repo-конвенции через Deckhouse annotations/labels, а не только `ServiceMonitor`.
3. Values per cluster по имени файла в `values/`, если collector простой.
4. Если нужны разные stage/prod defaults, внутри нового chart уже можно повторить layout `trivy-operator` с `values-global.yaml`.

Почему так:
- shared/internal exporter’ы в этом репо в основном живут в `common/*`
- standalone chart чище, чем встраивать collector прямо в `/common/trivy-operator`
- collector логически связан с Trivy, но по repo-паттерну это скорее sibling chart, чем часть upstream-like chart

Если хочешь, могу следующим сообщением дать уже совсем короткий skeleton-эскиз структуры файлов для `trivy-crd-collector` без редактирования репо.

**Analyzing ArgoCD Configuration**

I noticed that ArgoCD applies configurations per cluster based on filenames, which seems useful. I could mention how the repository convention values filenames by clusters. I thought about looking at the `nat-node-exporter.yaml` template to check annotations or services, but maybe that’s not needed right now. It's important to prepare concise findings, possibly outlining small internal exporter patterns like `kube-blender-exporter` and `prometheus-openstack-exporter` for clarity.
**Considering configuration patterns**

I'm working on kube-blender-exporter and its relationship with OpenStack and VMware patterns. It seems important to clarify whether exact production and staging settings are needed. I should adopt the Trivy operator's `values-global.yaml` overlay within the new chart while maintaining the chart's standalone nature. Including absolute file paths could enhance clarity, and maybe I can even add small code blocks to show metric patterns. I think two short code blocks, one for Deckhouse annotations and another for ServiceMonitor, would be beneficial. Overall, I want to keep the final response concise.
**Considering documentation best practices**

I’m pondering whether to mention line numbers in written prose. Formatting rules suggest that when referencing a file, the path should be surrounded by backticks without including line numbers. So, inline references to lines aren’t allowed. I might use two or three code blocks as evidence, ensuring the line numbers are correct. For instance, I'd reference deployment-exporter service block lines 36-53 and the trivy ServiceMonitor lines 1-10. Notably, I couldn’t find `ServiceMonitor enabled: true` for Trivy in the checked values, which could be a useful point to mention.
**Structuring export documentation**

I need to specify that this is based on a search. It's also good to mention that existing cluster values maintain Deckhouse pod annotations. There's a relevant dashboard in `common/trivy-operator/prod/templates/grafana-dashboard.yaml`, so I might consider mentioning that as an optional pattern for the collector too. Additionally, I want to highlight `common/prometheus-openstack-exporter/templates/alerts.yaml` alongside the previous file to showcase extras. It's important to note that exporters typically ship alerts and dashboards alongside the chart. I'll ensure the final output includes absolute paths.
