Terms in this definition
- Packet capture
Network Watcher feature that records a VM's traffic, filtered by 5-tuple and bounded by a time limit (18,000 seconds, or 5 hours, by default). It depends on the Network Watcher Agent extension.
- Connection Monitor
Continuously probes network paths from sources to destinations in Network Watcher. Each monitor accepts source VMs only from its own region, so multiple source regions mean multiple monitors.
- Virtual machines
Infrastructure-as-a-service compute giving complete control of the operating system, making it a fit for lift-and-shift moves and for software relying on OS-level pieces like COM.
- Azure Arc-enabled servers
Servers running Windows or Linux outside Azure that become Azure resources once the Azure Connected Machine agent is installed; data collection rules can then drive the Azure Monitor agent on them.
