It enables you to monitor\nyour networks in the following ways:\n\n- View the topology of your network infrastructure and deployments.\n- Check connectivity between network endpoints.\n- View the performance of your entire Google Cloud network and the performance of your project's resources.\n- Get insights, recommendations, and metrics about your firewall rules.\n- Automatically monitor your Virtual Private Cloud (VPC) network configurations and detect misconfigurations and suboptimal configurations.\n\nNetwork Topology\n----------------\n\nNetwork Topology is a visualization tool that shows the topology of your\nnetwork infrastructure:\n\n- Infrastructure view: Shows Virtual Private Cloud (VPC) networks, hybrid connectivity to and from your on-premises networks, connectivity to Google-managed services, and the associated metrics.\n- GKE Enterprise view (for GKE Enterprise enabled projects): Shows the infrastructure of your Google Kubernetes Engine (GKE) deployments: clusters, namespaces, workloads, pods, and their associated metrics.\n\nYou can also view metrics and details of network traffic to other Shared VPC\nnetworks and inter-region traffic. Network Topology combines\nconfiguration information with real-time operational data in a single view. This\nview makes it easier to understand networking relationships between various\nworkloads on Google Cloud and their current state, such as the traffic paths and\nthroughput between virtual machine (VM) instances.\n\nFor more information, see the [Network Topology overview](/network-intelligence-center/docs/network-topology/concepts/overview).\n\nConnectivity Tests\n------------------\n\nConnectivity Tests is a diagnostics tool that lets you check connectivity\nbetween network endpoints. It analyzes your configuration and, in\nsome cases, performs live data plane analysis between the endpoints. An endpoint\nis a source or destination of network traffic, such as a VM,\nGoogle Kubernetes Engine (GKE) cluster, load balancer forwarding rule, or an IP\naddress on the internet.\n\nTo analyze network configurations, Connectivity Tests simulates the\nexpected forwarding path of a packet through your Virtual Private Cloud (VPC) network,\nCloud VPN tunnels, or VLAN attachments. Connectivity Tests can also\nsimulate the expected inbound forwarding path to resources in your VPC\nnetwork.\n\nFor some connectivity scenarios, Connectivity Tests also performs\nlive data plane analysis. This feature sends packets over the data plane to\nvalidate connectivity and provides baseline diagnostics of latency and packet\nloss. If the route is supported for the feature, each test that you run\nincludes a live data plane analysis result.\n\nFor more information, see the [Connectivity Tests overview](/network-intelligence-center/docs/connectivity-tests/concepts/overview).\n\nPerformance Dashboard\n---------------------\n\nPerformance Dashboard gives you visibility into the performance of the entire\nGoogle Cloud network, as well as to the performance of your project's\nresources.\n\nWith these performance-monitoring capabilities, you can distinguish between a\nproblem in your application and a problem in the underlying Google Cloud\nnetwork. You can also investigate historical network performance problems.\n\nFor more information, see the [Performance Dashboard overview](/network-intelligence-center/docs/performance-dashboard/concepts/overview).\n\nFirewall Insights\n-----------------\n\nFirewall Insights helps you understand and optimize your firewall rules.\nIt provides insights, recommendations, and metrics about how your\nfirewall rules are being used. Firewall Insights also uses machine\nlearning to predict future firewall rules usage.\n\nFirewall Insights lets you make better decisions during firewall\nrule optimization. For example, Firewall Insights identifies\nrules that it classifies as overly permissive. You can use this information to\nmake your firewall configuration stricter.\n\nFor more information, see the [Firewall Insights overview](/network-intelligence-center/docs/firewall-insights/concepts/overview).\n\nNetwork Analyzer\n----------------\n\nNetwork Analyzer automatically monitors your Virtual Private Cloud (VPC)\nnetwork configurations and detects misconfigurations and suboptimal\nconfigurations. It provides insights about\nnetwork topology, firewall rules, routes, configuration dependencies, and\nconnectivity to services and applications. It identifies network failures,\nprovides root cause information, and suggests possible resolutions.\n\nNetwork Analyzer runs continuously and triggers relevant analyses based on\nnear real-time configuration updates in your network. If a network failure is\ndetected, it tries to correlate the failure with recent configuration changes to\nidentify root causes. Wherever possible, it provides recommendations to suggest\ndetails about how to fix the issues.\n\nFor more information, see the [Network Analyzer overview](/network-intelligence-center/docs/network-analyzer/overview).\n\nFlow Analyzer\n-------------\n\nFlow Analyzer lets you quickly and efficiently understand your\nVirtual Private Cloud (VPC) traffic flows without the need to write complex\nSQL queries for analyzing VPC Flow Logs.\nFlow Analyzer lets you perform\nopinionated network traffic analysis with 5-tuple granularity\n(source IP, destination IP, source port, destination port, and protocol).\n\nDeveloped using\n[Log Analytics](/logging/docs/analyze/query-and-view)\nand powered by [BigQuery](/bigquery),\nFlow Analyzer enables in-depth analysis of inbound and outbound\ntraffic of your VM instances. It lets you monitor, troubleshoot, and optimize\nyour networking deployment for better performance and enhanced security which\nhelps ensure compliance, and save on costs.\n\nFlow Analyzer analyzes VPC Flow Logs data stored in a log\nbucket ([record format](/vpc/docs/about-flow-logs-records#record_format)). To use\nFlow Analyzer, you must select a project with a\nlog bucket that contains VPC Flow Logs. For more information, see the\n[VPC Flow Logs overview](/vpc/docs/flow-logs). VPC Flow Logs can\nbe used for network monitoring, forensics, real-time security analysis, and\nexpense optimization.\n\nFor more information, see the [Flow Analyzer overview](/network-intelligence-center/docs/flow-analyzer/overview)."]]
