Metrics tool - There are some limitations on how many resources you can deploy within an Azure virtual environment. Packet capture tool - Captures traffic to (and from) a virtual network and stores the packets for offline analysis. It even keeps a record of the number of packets dropped during the connection troubleshooting check. Also provides min, max, and average latency between the source and destination. Provides hop to hop paths from the source to destination through visually appealing Visio diagrams. It also provides the root cause to investigate or remediate further.Ĭonnection troubleshooting tool - Used to test the connection between two VMs, URL, FQDN, and IPv4 addresses. It tests the routing rules by allowing you to enter the source and destination IP addresses of your endpoints. IP flow verify - This tool informs us which security rule is blocking the communication from (or to) the virtual network. Diagnostic toolsįrom a diagnostic perspective, Azure Network Watcher offers a handful of tools to diagnose traffic issues and load balance issues in your virtual network. This visually represents the IP addresses and hostnames in your Azure Virtual Network. The best aspect of the NPM is that as you add more and more endpoints to your network, it creates a visual diagram using a topology tool. The NPM monitors the connectivity strength between Azure Virtual Network deployments and the on-premise network(your office/branch network). This element helps to monitor and report the performance of the network infrastructure endpoints in the virtual network. If someone applies a new route or a new security rule that blocks the communication, the connection monitor immediately notifies the user the current endpoint is not reachable along with the reason. Let us assume you have a VM hosting a web application and another VM hosting a database from which the former gets data. Knowing the latency of your virtual network, you will know the Azure region where you will get better service. It is also used to measure latency points, where latency is the time taken by data packets to travel from one designated point to the other. It also ensures there is connectivity between 2 points(for instance the connection between a web application and database). This allows you to monitor all the components from one endpoint to another endpoint. Here is the breakdown of some of the common Azure Network Watcher elements. Azure Network Watcher ElementsĪzure Network Watcher allows you to gain insights into your network performance using several elements. To monitor PaaS resources there are many other resources offered by Azure such as Azure Monitor and Log Analytics. However, it is not suitable for PaaS-related networks or web analytics. Without knowing what Azure Network Watcher does, you might end up deleting it. Azure automatically adds the Azure Network Watcher when you build or update an Azure Virtual Network into your subscription. Let’s find out more in this post.Īzure Network Watcher provides 360-degree monitoring and logging for all IaaS virtual networks. To monitor all the ins and outs of your Azure virtual network, you have the Azure Network Watcher which provides several promising features over other network watchers in the market. By monitoring it, you can ensure that your data is secure and even take preemptive measures in case your virtual network is having connection issues. You have to monitor the health and status of your Azure Virtual Network. However, it does not stop with all the data assets being deployed to the cloud. When you deploy data assets in the Azure cloud, you simply build a virtual network and set up all the ties to your on-premise network via express route or independently run it in the cloud and have your virtual network setup.Įxpress route helps your on-premise network(here on-premise network refers to your corporate IT network) to connect to Microsoft Azure cloud over a private network via a connectivity provider. By 2025, it is estimated that the data deployed in the cloud would cross a staggering mark of 100 zettabytes! But even before the onset of the pandemic, cloud deployments had been rampantly growing since the past decade. With remote work being the new norm, businesses have started deploying all their assets into the cloud.
