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.

Introduction to IRIS for SQL Developers and DBAs.

Are you familiar with SQL databases, but not familiar with IRIS?  Then read on...

About a year ago I joined InterSystems, and that is how IRIS got on my radar.  I've been using databases for over 40 years—much of that time for database vendors—and assumed IRIS would be largely the same as the other databases I knew.  However I was surprised to find that IRIS is in several ways quite unlike other databases, often much better.  With this, my first article in the Dev Community, I'll give a high-level overview of IRIS for people that are already familiar with the other databases such as Oracle, SQL Server, Snowflake, PostgeSQL, etc.   I hope I can make things clearer and simpler for you and save you some time getting started.

Avoiding SQL Injection in InterSystems IRIS: The Case for Secure Query Practices

SQL injection remains one of the most critical vulnerabilities in database-driven applications, allowing attackers to manipulate queries and potentially access or compromise sensitive data. In InterSystems IRIS, developers have access to both Dynamic SQL and Embedded SQL, each with distinct characteristics. Understanding how to use them securely is essential for preventing SQL injection.

The Problem: Dynamic SQL and SQL Injection

Dynamic SQL constructs queries as strings at runtime. While this offers flexibility, it also creates a vulnerability if user input is not handled correctly.

%ZEN.Dialog.namespaceSelect is not showing in some namespaces and giving a 403 Page not found error. Any ideas what could be wrong?

I have an issue and can't seem to find the problem.

Issue

 In some namespaces i get a 403 Page not Found error for healthconnect/csp/healthshare/[NAMESPACE]/%25ZEN.Dialog.namespaceSelect.cls ; healthconnect/csp/healthshare/[NAMESPACE]/%25ZEN.Dialog.finderDialog.zen  && healthconnect/csp/healthshare/[NAMESPACE]/_CSP.UI.Portal.About.zen

 

Iris setup

It is currently configured in a mirror group and on the other mirror-member i don't encounter the issue. (I have checked if it was because of the member-type Primary and Backup). 

The user that I am using has the %All role.

IRIS-HL7v2Gen: Dynamic HL7 Test Message and Structure Generation for Healthcare Integration

image
Hi Community,
In this article, I will introduce my application iris-HL7v2Gen .

IRIS-HL7v2Gen is a CSP application that facilitates the dynamic generation of HL7 test messages. This process is essential for testing, debugging, and integrating healthcare data systems. The application allows users to generate a wide variety of HL7 message types, validate their structure against HL7 specifications, explore the message hierarchy, and transmit messages over TCP/IP to production systems. These features are particularly useful in settings where compliance with HL7 standards is mandatory for interoperability between different healthcare organizations or systems.

Do you use client-side editing in VS Code? We want your feedback on the latest improvements!

Since our previous announcement, we have introduced several incremental improvements to the client‑side editing experience in VS Code. These updates focus on preserving developer‑authored formatting when synchronizing with the server.

What Changed

Client‑side *.cls files previously lost certain formatting details during compilation, including keyword casing (e.g., classmethod → ClassMethod), normalization of blank lines between class members, and removal of line breaks within parameter lists.

Developing and maintaining code for interoperability components within a healthcare institutional environment

There are lessons we learned from developing and maintaining code for interoperability components within a healthcare institutional environment.

The plane is already flying

Be prepared to rebuild, improve, extend, and fix the plane mid-flight.
 

Maintenance windows for hospital systems are often very limited, with some required to be operational 24/7. While the health critical systems such as imagery modalities or registration kiosks — or at least their critical functions — must operate autonomously, efficiency and usability may be compromised when interoperability components malfunction.

Python method does not work in Business Process

Hi all.

I have a rather strange problem.

I've created a method in Python to create a vector for a vector search. So far, so good.

If I call this method from the terminal, it works correctly:

But if I make this same call from a code block in a Business Process, it gets stuck, doesn't respond, and throws the following error:

Does anyone know what's happening and how to fix it?

Thank you in advance

Rebuilding the IRIS Production Monitor as a Modern Angular App — Looking for Feedback

Hi community,

I've been working on a side project that I'd love to get some eyes on: a ground-up rebuild of the classic IRIS Production Monitor using a modern web stack. The existing ZEN/CSP-based portal does the job, but I wanted to explore what a contemporary, real-time version of it could look like.

What it is

A standalone Angular web application that connects to any Interoperability-enabled IRIS namespace and gives you a live view of your production — services, processes, operations, queues, event log, and message traffic — all in one screen.

Dark Mode for HealthShare Management Portal - Visual Accessibility Need

Hello InterSystems Community,

I hope you're all doing well. I'm reaching out to ask if there's any way to enable a dark theme or dark mode for the HealthShare Management Portal.

Background

I have a visual impairment (amblyopia/lazy eye) which means I'm nearly blind in one eye. Like many people with visual difficulties, I find that bright white backgrounds and interfaces cause significant eye strain and fatigue. This makes it challenging to work with the Management Portal for extended periods.

Building a Medical History Chatbot - FHIR, Vector Search and RAG for beginners

Introduction

Earlier this year, I set about creating kit to introduce young techy folk at a Health Tech hackathon to using InterSystems IRIS for health, particularly focusing on using FHIR and vector search.

I wanted to publish this to the developer community because the tutorials included in the kit make a great introduction to using FHIR and to building a basic RAG system in IRIS.

How to add your APIs to the Interoperability Production

I may have mentioned this before: I believe the Visual Traces, these sequence diagrams with full content of each step, are a fantastic feature of the IRIS Data platform! Detailed information about how the API works internally, as a visual trace, can be very useful for projects on the IRIS platform. Of course, this applies when we are not developing a high-load solution, in which case we simply don't have time for saving/reading messages. For all other cases, welcome to this tutorial!
