Monitoring Managed Cloud Standard
Version:
You can stay constantly updated on the performance and availability of your Managed Cloud solution by using the built-in monitoring services:
- Metrics exporters - libraries that help to export metrics from services and infrastructure to an existing Prometheus server.
- Prometheus - scrapes metrics from services, aggregates and stores data, and allows other services such as Grafana to collect such metrics.
- Grafana - collects metrics from Prometheus and visualizes them.
Authentication in Grafana
Authentication in Grafana
Grafana is integrated with the Azure Active directory and Basic Authentication is disabled. Therefore, you must choose the Sign in with Microsoft authentication option and use your Microsoft work account.
Dashboards
Dashboards
You can search for dashboards by the dashboard name, filtered by one (or many) tags or filtered by starred status. You can access dashboard search through the dashboard picker, available in the dashboard top navigation area. You can also open dashboard search by using the shortcut F.
The following default dashboards are available:
| Dashboard | Description |
|---|---|
| Container overview | Lists all containers with their namespace and pod. Provides the status of each container and the total number of healthy/unhealthy and/or stopped containers. |
| Host Disk Overview (Linux only) | Exposes node filesystem and disk I/O metrics such as read-write time spent, the filesystem available space, and so on. |
| Host Disk Overview (Windows only) | States the filesystem available space. |
| Ingress Overview | Provides the Ingress metrics for each Sitecore role and Grafana. |
| Kubernetes Cluster | Provides a high-level overview of the Kubernetes cluster. |
| Kubernetes Pod Overview | Exposes memory and CPU request, limits, and utilization per pod for all namespaces including system. It provides live logs. |
| Linux Node Overview | Provides detailed information about Memory/CPU/Disk utilization for each Linux Node. |
| MsSql Elastic Pool | Provides detailed information about MsSql Elastic Pool utilization. |
| Redis Server Overview | Exposes general Redis metrics. Similar to native Redis "INFO" command. |
| Windows Node Overview | Provides detailed information about Memory/CPU/Disk utilization for each Windows node. |
Alerts

Alerts proactively notify you when issues are found with your Managed Cloud solution. They allow you to identify and address issues before the users of your system notice them. The following table lists the available alerts:
