Installation and Configuration

What are the resource requirements for
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?

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?

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.

How do I find out
VMware Aria Operations for Networks
 collector VM IP from the UI?

Go to Settings page and select
VMware Aria Operations for Networks
 Infrastructure menu option. The IP address of both,
VMware Aria Operations for Networks
 Platform and
VMware Aria Operations for Networks
 collector VMs is displayed.

What should I do if
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:
  • Verify
    VMware Aria Operations for Networks
     platform pairing status with
    VMware Aria Operations for Networks
     collector using the CLI
    show-connectivity-status
     .
  • If the pairing stating is shown
    Passed
    , open the platform UI in a new browser window and login to check status.
  • If the pairing status is showing
    Failed
    , then the shared secret key specified during the
    VMware Aria Operations for Networks
     collector OVA deployment could be wrong. To fix this problem, use 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 can detect
    VMware Aria Operations for Networks
     collector.
  • If the
    show-connectivity-status
     shows network reachability to
    VMware Aria Operations for Networks
     Platform as
    Failed
    , then verify whether
    VMware Aria Operations for Networks
     platform is reachable from
    VMware Aria Operations for Networks
     collector VM using the
    ping
     command.
  • If it is not reachable, then verify if NTP, DNS, gateway, and other network parameters are configured correctly using
    show-config
     command.
  • If any of the network parameters is not configured correctly, use the
    setup
     command to modify the network configuration parameters.

What should I do if I forget my login credentials?

If you are the UI local user: Contact
VMware Aria Operations for Networks
 UI administrator to reset the credentials for you.

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 a
    destination_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
