    1. Enable NSG Flow Logs for secured Storage Accounts

      At the moment, it's apparently not possible to use NSG Flow Logs with secured Storage Accounts, even if the exception "Allow trusted Microsoft services to access this storage account" is enabled on the Storage Account.

      It would be really helpful if you could add the Network Watcher this list of trusted Microsoft servies, so we can use secured Storage Accounts to store our NSG Flow Logs on.

    2. Network Watcher Topology should get information for resources in different resource group than VNET

      The preview of Network Watcher has a Topology feature which draws objects connected to a specific VNET, which is great. But, I noted that for a full topology, ALL resources need to be on the same Resource Group than the VNET chosen. That doesn't make sense, because is pretty common to have VMs and NICs on different RGs. Would be great if you choose a RG and a VNET as a starting point, and Topology feature gather all other resources interconnected independently of their RGs.

    3. Network Watcher in Azure Stack?

      Can you provide any guidance on when we could expect to see this awesome tool in Azure Stack? it would be hugely beneficial

    4. ARM Template support for NSG Flow logs

      Add support to configure NSG Flow logs using Azure Resource Manager template.

      The goal is to have Azure Policy to deploy NSG Flow Log configuration.

      Reference to Docs:
      https://docs.microsoft.com/en-us/azure/network-watcher/traffic-analytics-faq#can-i-configure-traffic-analytics-using-powershell-or-an-azure-resource-manager-template-or-client

      Thanks for the valid suggestion. Your feedback is now open for the user community to upvote which allows us to effectively prioritize your request against our existing feature list and also gives us insight into the potential impact of implementing the suggested feature

    5. NSG Flow logs

      Currently NSG Flow Logs are do not have the ability to publish to Azure Event Hub as other logs do.

      It would be invaluable for this facility to be made available to allow onward transformation of log data (via Azure Functions) prior to ingest into products such as Splunk.

      Thank you for your feedback. Today publishing NSG Flow Logs to an Event Hub is not currently supported natively. We will continue to evaluate this suggestion and update the status accordingly.

      Today, if you are interested in transforming and streaming NSG Flow Logs to a 3rd party endpoint, we have published a sample here that leverages an Azure function: https://github.com/Microsoft/AzureNetworkWatcherNSGFlowLogsConnector

      Splunk has also published a blog with guidance on integrating NSG Flow Logging data here: https://www.splunk.com/blog/2017/02/20/splunking-microsoft-azure-network-watcher-data.html

    6. Network Monitor Dashboard

      Provide a dashboard to help understand the Azure network topology and to visualise the NSG rules

    7. Introduce alert mechanism in network watcher?

      It would be great if you can introduce an alert mechanism with all the monitoring it does. For exmaple : similar to what we have for Azure VMs, when the cpu utilization goes down we can configure an alert for the based on the threshold.

      Network watcher monitors many many things it should have the capability to generate alerts based on it's monitoring capabilities.

    8. Next Hop - show which route entry was used

      When you use next hop feature, it shows the route table ID that was used - but it would be nice if it showed the rule name from the route table as well.

    9. Allow access to packet capture while capture is running.

      When a packet capture is running in the Network watcher, you currently have to wait until the capture is complete to view the .pcap file. It would be useful to be able to look at the .pcap file while the capture is running.

    10. STOP creating random Resource Groups!

      Honestly, what are we going to do with you MSFT when it comes to RBAC?

      When MSFT puts services into Preview and often months or years after they are so-called GA they still fail to recognize that they are violating Governance, RBAC, rules allowing Azure Services to randomly create Resource Groups in any given Azure Subscription.

      The two biggest violators of this right now are Databricks and Network Watcher.

      In most cases our clients should be refusing to use these services until they are capable of adhering to Governance and Security rules being enforce by InfoSec and others.

      Resource Groups are sacred beasts…

    11. ad snmp to service endpoint monitor

      The new service endpoint monitor is a very welcome addition. The only thing now missing from the OMS solution is a user-friendly way to collect SNMP data. Mainly for monitoring bandwidth usage etc on firewalls & routers.The linux snmpd to OMS logs option is to cumbursome because there's no way to centrally configure this.A snap option in the service endpoint monitor would be perfect for this!

    12. More frequent NSG Flow log rollover, and consumption into Traffic Analysis

      It would be useful to have NSG flow logs consumed by Traffic Analysis more frequently than every hour (ever minute would be great!).

      Currently the delay is too long to be useful for real-time troubleshooting, and useful only for analysis retrospectively.

    14. Let IP flow verify show which NSG is matched.

      The current implementation of IP flow verify in network watcher shows the name of the rule that is matched for allowing/denying traffic. It doesn't show the name of the effective NSG itself (only the rule in an NSG). A useful addition would be to show the name of the NSG in additional to the matched rule. A click through to the NSG for instant changes would help as well.

    15. Network Monitoring API or Powershell Cmdlet for adding/removing nodes to be monitored

      Hello,
      Is it possible to use OMS - NPM with some kind of API or Poweshell Cmdlet.

      I have the following example that I need to solve:

      We create VMs and then sometimes they are turned off as they no longer needed for whatever reason. I do not want to still monitor network traffic to this node/VM on Azure.

      Currently we have to use the NPM UI configuration to select the node and click the checkbox for 'Use for monitoring` which is open to human error for when we forgot to disable this and more likely we forget to re-enable…

    17. Azure Networking Traffic Simulator

      You should consider adding a Azure Networking Traffic Simulator somewhere in Azure to provide better tooling for troubleshooting and configuring NSG firewall rules.

    18. Availability Test Integration with Application Insights

      Right now App Insights provides availability tests, but they can only hit external facing sites. The Service Endpoint Monitor fills that gap for any internal sites, but the customer now has to manage 2 separate tool configurations. It would be ideal if App Insights would allow OMS nodes as options on the “Test Locations” list, so all URL testing would be configured in the same place and the respective engines would execute them appropriately

    19. Network Flow Logs should show public destination IP

      When looking at the NSG Flow Logs at the moment, all traffic from e.g. my local laptop, seems to be flowing directly to the private IP address of my VM.

      The source IP is the public IP address of my laptop and the destination IP should, in my opinion, be the public IP address of the VM, not the local private subnet IP (10.x.x.x), when traffic is inbound from the internet.

      Yes, the NSG Flow Logs will record the private IP address of the Network Interface. There are scenarios where public IP addresses can be shared across resources (e.g. using an Internet Load Balancer or Application Gateway) therefore we display private IP addresses to be most specific.
      The need to preserve Public IPs address traffic flow as part of the flow logs is valued feedback. Thank you for contributing.

    20. Can't get NSG Flow Logs to show up in Azure Monitor Logs!

      I can't find corresponding flow logs for the action that I manually triggered. Here is what I am trying to do and I am expecting flow logs to show up after few (4) minutes but they don't!

      1) Call API at the Application Gateway @https://api.aspnet4you.com/api/customer/FindAllCustomers?country=United%20States&state=Washington&city=Seattle

      2) Query to find app gateway access logs and they show up in about 3 minutes:
      AzureDiagnostics
      | where TimeGenerated >= now(-15m)
      | where clientIP_s !=""
      | where Category == "ApplicationGatewayAccessLog"

      3) Query NSG Flow logs but NO Result Found!
      AzureNetworkAnalytics_CL
      | where TimeGenerated >= now(-15m)
      | where SubType_s == "FlowLog"
      | extend dir…
