VMware Aria
Operations for Networks?
VMware Aria
Operations for Networks
?Refer to the
VMware Aria
Operations for Networks
Installation Guide for Resource Requirements. What happens if I enter the incorrect key
during VMware Aria
Operations for Networks collector
OVA deployment?
VMware Aria
Operations for Networks
collector
OVA deployment? The secret key is not validated during
VMware Aria
Operations for Networks
collector OVA deployment.
The deployment completes even with incorrect secret key. However, pairing can fail
and VMware Aria
Operations for Networks
collector does
not show up as detected on VMware Aria
Operations for Networks
UI. To correct the shared secret, log in to
VMware Aria
Operations for Networks
collector CLI and run the
set-proxy-shared-secret
command to set the correct secret
key. This command replaces the old key with the new one, and therefore, VMware Aria
Operations for Networks
platform detects
VMware Aria
Operations for Networks
collector and
pairs up. How do I configure DNS after VMware Aria
Operations for Networks collector OVA is
deployed?
VMware Aria
Operations for Networks
collector OVA is
deployed? Log in to
VMware Aria
Operations for Networks
collector CLI, and run the change-network-settings
command. This interactive command will provide the user an option to add or modify
DNS after which the VMware Aria
Operations for Networks
collector will be reconfigured with the new DNS. If any of the network
parameters is not configured correctly, use the change-network-settings command
to modify the network configuration parameters.

after deploying VMware Aria
Operations for Networks
collector OVA?
VMware Aria
Operations for Networks
collector is not detected in 5 minutes
after deploying VMware Aria
Operations for Networks
collector OVA? Log in to
VMware Aria
Operations for Networks
collector using consoleuser
(refer to the
VMware Aria
Operations for Networks
Command Line
Interface Guide) and verify the following: - VerifyVMware Aria Operations for Networksplatform pairing status withVMware Aria Operations for Networkscollector using the CLIshow-connectivity-status.
- If the pairing stating is shownPassed, open the platform UI in a new browser window and login to check status.
- If the pairing status is showingFailed, then the shared secret key specified during theVMware Aria Operations for Networkscollector OVA deployment could be wrong. To fix this problem, use theset-proxy-shared-secretcommand to set the correct secret key. This command replaces the old key with the new one, and therefore,VMware Aria Operations for Networksplatform can detectVMware Aria Operations for Networkscollector.
- If theshow-connectivity-statusshows network reachability toVMware Aria Operations for NetworksPlatform asFailed, then verify whetherVMware Aria Operations for Networksplatform is reachable fromVMware Aria Operations for Networkscollector VM using thepingcommand.
- If it is not reachable, then verify if NTP, DNS, gateway, and other network parameters are configured correctly usingshow-configcommand.
- If any of the network parameters is not configured correctly, use thesetupcommand to modify the network configuration parameters.

VMware Aria
Operations for Networks
supports multiple vCenter Servers and NSX Manager. Which services of VMware Aria
Operations for Networks need Internet access and why?
VMware Aria
Operations for Networks
need Internet access and why?VMware Aria
Operations for Networks
supports remote home calling feature that requires
Internet access. This feature or services allow the VMware Aria
Operations for Networks
team to gain a better understanding of
customer environments and proactively troubleshoot or repair issues. The following
services need Internet access: - Auto Update Service (svc.ni.vmware.com:443):VMware Aria Operations for Networksuses this service to contact the remote upgrade host and pull in newly released bits as it become available, and the user gets a UI notification when the updates are available. This service is enabled by default, but you can deactivate this service through UI or usingonline-upgradecommand through CLI.
- Performance Telemetry Service (svc.ni.vmware.com:443): Certain metrics related to key services and performance ofVMware Aria Operations for Networksare periodically gathered and uploaded for theVMware Aria Operations for Networks. The support team monitors these metrics and identifies any anomaly in the environment so that the support team can act before it impacts any critical services. This service is deactivated by default, but you can enable/deactivate this service usingtelemetrycommand through CLI. More information is available here: https://kb.vmware.com/s/article/59242
- Support Service (support2.ni.vmware.com:443): This service establishes remote secured tunnels to theVMware Aria Operations for Networkssupport host that allow authorized personnel to remotely access and work on deployments. It is deactivated by default and can be enabled/deactivated through UI as well as "support-tunnel" CLI.
- Registration Service (reg.ni.vmware.com:443): For registering the appliance with all external services. It will enable trusted communication between above mentioned services. When setup has access to internet, registration happens automatically. In an isolated environment it can be done using "offline-registration" CLI (Please refer to CLI guide for more details). It is required for enabling Support Tunnel.
If the
VMware Aria
Operations for Networks
platform is behind an Internet
proxy, allow the following domain names and ports:
Service | URL | Port |
---|---|---|
Upgrade Service/Metric Service | svc.ni.vmware.com | 443 |
Support Tunnel Service | support2.ni.vmware.com | 443 |
Registration Service | reg.ni.vmware.com | 443 |
How to deactivate internet access from the
appliance?
The following services use secure remote/internet
services:
- Auto Update Service
- Performance Telemetry Service
- Support Service
- Registration Service
VMware Aria
Operations for Networks
needs internet access if any one of these services is
enabled.What is port
aggregation and what is the mechanism to do it?
Port aggregation is built in
to aggregate the ephemeral port flows – like dynamic FTP, Oracle, MS-RPC etc.
This helps in reducing the number of flows in system and provide an aggregated
view for large number of flows that are essentially for the same service.
The mechanism to do it is as
follows:
- For first three days of noticing adestination_ip, we will aggregate destination ports on that particular IP in buckets of 10K and start building a port-profile for that IP (build a port-profile per destination IP).
- After three days, once we have built a profile, we will start aggregating port ranges where the port density is high (reflect ephemeral port opening pattern). The ranges themselves will be dynamic in size such as 100, 1,000, 10,000, and will be created depending on how many ports are being opened and how widespread they are in the given range of aggregation.This decision happens independently for each server IP address.
- This will enable high-port flows to be reported with no aggregation where there is no bulk port open activity happening and also let dynamic aggregation to be applied where such activity is happening.
- The profile is continually updated in a time-decayed manner to account for new ports opening up or older ones being not used any more.
How do I change the IP Address, Gateway, or
Netmask after VMware Aria
Operations for Networks OVA
is deployed?
VMware Aria
Operations for Networks
OVA
is deployed? To change
VMware Aria
