Linux

Update (February 2026): This post has been updated to reflect the current best practices for monitoring FlashArray using OpenMetrics. Starting with Purity//FA 6.7.x, FlashArray includes a native OpenMetrics exporter, eliminating the need for a separate exporter service/container. The configuration examples below now demonstrate direct-to-array scraping.

This post introduces you to monitoring your Pure Storage FlashArray using OpenMetrics. It shows you how to get started quickly using Docker Compose to monitor your Pure Storage FlashArray environment.

In this post, we’re going to walk through configuring Active Directory authentication for SQL Server on Linux. We will start by joining the Linux server to the domain, configuring SQL Server on Linux to communicate to the domain, and then use adutil to create our AD users and set up Kerberos for SQL Server login authentication.

Before getting started

First, let’s get some environment requirements set. We’ll need an Active Directory domain, a Linux host to install SQL Server on, some DNS records for that host, and the DNS client on that host configured for our environment. Here are the settings I used in this walk-through.

Ever need to set your web server a specific protocol version of TLS for web servers and need a quick way to test that out to confirm? Let’s check out how to use curl to go just that.

This code here uses curl with the parameters --tlsv1.1 --tls-max 1.1, which will force the max TLS protocol version to 1.1. Using the --verbose parameter gives you the ability to see the TLS handshake and get the output sent to standard out.

In this post, we will explore how a Pod name is generated, Pod Name lifecycle, how it’s used inside a Pod to set the system hostname, and how the system hostname is used by SQL Server to set its server name metadata.

Pod Naming in Deployments

When deploying SQL Server in Kubernetes using a Deployment, the Pod created by the Deployment Controller will have a name with a structure of <DeploymentName>-<PodTemplateHash>-<PodID> for example, mssql-deployment-8cbdc8ddd-9n7jh.
