Networkers running enterprise and critical service provider infrastructure need infrastructure-savvy analogs of the same observability principles and practices being deployed by DevOps groups. The critical context that enables teams to ask questions about users, applications, and customers (and not just IP addresses and ports).

There are a number of definitions, but observability in the DevOps world has been about using diverse telemetry to know the internal states of systems over time (generally focused around metrics, logs, and traces), and providing answers to the unbounded questions needed to run modern applications. The Move to Observability.

Many, if not most, DevOps teams and others working across multiple tools use Grafana as the primary way they do reporting and analysis of data for operational use cases spanning many monitoring systems. Automatic DNS resolution option for IP addresses in Grafana. New installation documentation found here.

The concept of observability has taken hold in the DevOps, SRE and application performance monitoring (APM) space. Port numbers and IP addresses are less useful in traffic analytics. And, observability as a concept resonates with the way application, DevOps and SRE teams see their challenges. What is observability?

It’s one thing to say, “My Kubernetes clusters should not be communicating with external IP addresses,” or “unencrypted HTTP or FTP traffic should not appear in these specific network zones.” This helps in fortifying the security posture and addressing vulnerabilities proactively. It is another thing to enforce these rules.

In Data Explorer, we built a query, using the time range of the incident, with “Full Device” as the group-by dimension, and we filtered the query down to the IP address for gcr.io. After disabling the port, we investigated and discovered that one of our remote contractors had connected to the WiFi in our datacenter.

This is happening at the same time that SRE and DevOps teams are actually speeding up and enjoying the agility of the cloud. And it’s not like the network teams had to worry about fixing failed line cards or erroring ports. Packet Address : AWS recently added the ability to see inside network overlays (GRE, etc.)
