Archiving Network Flows from vRealize Network Insight to Log Insight

vRealize Network Insight (vRNI) captures all traffic going through the network. It stores the traffic in flow records, and these are made up out of a source, destination, protocol, and port number. The metrics are attached so you can get a nice graph of the traffic behavior.

vRNI Flows and context

After creating the flow, vRNI goes on and attaches a lot of context to that flow: Is it coming from a VM? Is there a firewall rule attached? Which vCenter is this flow going through? What kind of SD-WAN Policies are attached? If any of this context changes (i.e., a VM got renamed), … Read more

Exporting Dashboards from vRealize Log Insight with Python

You can create some pretty cool and quick dashboards with vRealize Log Insight. Send it some data, set some filters, and create widgets that represent the data in a good way. 

I just finished creating some good usage dashboards for the vRealize Network Insight Field Demo instances we have. The NGINX logs are sent via the log insight agent to vRLI, and then I filter out the unique visitors, popular searches, pinboards, and more. I wanted to see how often the field demo gets used and what’s being used.

The only problem is that vRLI doesn’t support generating scheduled reports, … Read more

IP Address Management with vRealize Network Insight

vRealize Network Insight knows all and see all that’s happening within a network. Due to the search engine and the ability to pull out any data on the infrastructure, new use cases pop up now and then. Lately, I’ve been approached by a few organizations that are using Network Insight as an IP Address Management (IPAM) system, or to complete their existing IPAM system and compare and contrast it to the live infrastructure.

Here are a few examples: checking whether which IP addresses are free in a particular IP range. Comparing the IPAM registrations to the IP addresses that are Read more
