Monitoring with the Pure Storage FlashArray OpenMetrics Exporter

This post introduces you to the Pure Storage FlashArray OpenMetrics Exporter. It shows you how to get started quickly using Docker Compose so you can monitor your Pure Storage FlashArray environment. I implemented this in Docker Compose since that handles all the implementation and configuration steps for you. It specifically configures Prometheus’ data source and a Grafana dashboard for monitoring. Tip: If you’re building a persistent monitoring solution, I suggest using a dedicated Linux server running Docker Engine (Server) for Linux.

Configure SQL Server on Linux for Active Directory Authentication

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.

Testing for Specific Versions of TLS Protocols Using curl

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.

Persistent Server Name Metadata When Deploying SQL Server in Kubernetes

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.
