Adding `nfsiostat` to SystemPerformance

Already included in SystemPerformance

There are nfs disk commands (including nfsiostat) included with SystemPerformance, but disabled by default. Enable them by running:

$$Enablenfs^SystemPerformance()

Doing so will add the following nfs commands, for example, on Linux:

  1. /usr/sbin/nfsstat -cn
  2. /usr/sbin/nfsiostat [interval] [count]

Ensure the commands are installed and runnable from the OS :)

This can be subsequently disabled via $$Disablenfs^SystemPerformance()

Adding a generic command to SystemPerformance

Adding an arbitrary OS tool creates a "user" command under ^IRIS.

Continuous FHIR conformance with IRIS/HealthShare: regression testing + drift tracking patterns

Hello everyone,

I am André from MedVertical. We are exploring InterSystems-native ways to operationalize continuous FHIR conformance: repeatable regression runs, baseline/delta comparisons, and evidence-style reporting to detect drift after releases and IG changes.

In many FHIR implementations, validation is done “point-in-time” in pre-prod, but conformance degrades in production due to IG/profile updates, terminology changes, mapping evolution, upstream releases, and configuration drift.

Sharding and Scalability in InterSystems IRIS: A Beginner's Guide

As applications grow, every database eventually hits scaling limits. Whether it's storage capacity, concurrent users, query throughput, or I/O bandwidth, single-server architectures have inherent constraints. This guide explains fundamental approaches to database scalability and shows how InterSystems IRIS implements these patterns to support enterprise-scale workloads.

We'll explore two complementary scaling strategies: horizontal scaling for user volume (distributing computational load) and sharding for data volume (partitioning datasets). Understanding the general principles behind these approaches will help you make informed decisions about when and how to scale your IRIS applications.

The examples in this guide use InterSystems IRIS in Docker containers.

Security in IRIS

Security is fundamental to enterprise application development. InterSystems IRIS provides a comprehensive security framework that protects data, controls access, and ensures compliance. This guide introduces essential security features for developers new to IRIS, covering authentication, authorization, encryption, and practical implementation strategies.

When to account for useIrisFsGroup in your IKO Deployments

If you look at the values.yaml of the IKO's Helm chart you'll find:

useIrisFsGroup: false

Let's break down what it is and in what situations you may want to set it to true.

FsGroup refers to the file system group.

By default, Kubernetes volumes are owned by root, but we need IRIS to own its files (IRIS in containers is installed under irisowner user). To get around this we employ one of two methods:

1) initContainers

The initContainers run before app containers (like IRIS) in a pod. They generally set up the environment for the application and then run to completion/terminate.
