They emit Service Fabric health reports, diagnostic telemetry and ETW events, then go away until the next round of monitoring. Observers are specialized objects that monitor, point in time, specific resources in use by user service processes, SF system service processes, containers, virtual/physical machines. When FabricObserver gracefully exits or updates, it will clear all of the health events it created.įabricObserver comes with a number of Observers that run out-of-the-box. You can clone the repo, build, and deploy or simply grab latest tested SFPKG with Microsoft signed binaries from Releases section, modify configs, and deploy. To quickly learn how to use FO, please see the simple scenario-based examples. If you run your apps on Service Fabric, then you should definitely consider deploying FabricObserver to all of your clusters (Test, Staging, Production). The latest member of the family is FabricHealer, which works in conjunction with FabricObserver to auto-mitigate service, node and VM level issues reported by FO. Read more about Service Fabric health monitoringįabricObserver is one member of a growing family of open source Service Fabric observability services. Running side-by-side with existing monitoring services, FabricObserver provides useful and timely health information for the nodes (VMs), apps, and services that make up your Service Fabric deployment. Each FO service instance knows nothing about other FO instances in the cluster, by design. Supports Configuration Setting Application Updates for any observer for any supported setting.įabricObserver targets SF runtime versions 9 and higher.įO is a Stateless Service Fabric Application composed of a single service that runs on every node in your cluster, so it can be deployed and run alongside your applications without any changes to them.In this way, FabricObserver is also an 'Observer' platform. Provides an easy-to-use extensibility model for creating custom Observers out of band (so, you don't need to clone the repo to build an Observer).Runs on multiple versions of Windows Server and Ubuntu.Monitors a broad range of physical machine resources that tend to be very important to all Service Fabric services and maps these metrics to the related Service Fabric entities.FabricObserver (FO) is a production-ready watchdog service with an easy-to-use extensibility model, written as a stateless, singleton Service Fabric.
