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.

Announcement KC Lu · Mar 16

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.

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.

As part of the new Interoperability UI wave (see what was new in 2025.1, and 2025.3 by @Aya Heshmat), v2026.1 which is available already as a Developer Preview, and this could be a reason for you to give it a ride - will be shipping the new UI for the Message viewing and searching, including Visual Trace (and other UI goodies).

He's a quick teaser:

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!

ObjectScript Search — Full-Text Server-Side Search for VS Code, Right Now

ObjectScript Search icon

If you have ever dug through a large IRIS namespace looking for where a particular string, method call, or pattern was used, you know the pain: there was no built-in way to do a grep-style search across your server-side ObjectScript code from VS Code — at least not without jumping through some hoops.

That is what ObjectScript Search fixes.

Try it today with a simple install from the VS Code Marketplace. If you don't like it, uninstalling is just as easy. But I think you will like it — it is a huge quality-of-life improvement for anyone doing ObjectScript development in VS Code.

Cleaning up EnsLib.SQL.Snapshot in BPL's

We are trying to track down significant growth within our Namespaces, one big culprit is Ens.AppData (EnsLib.SQL.Snapshot). 

Within many of our BPL's we use EnsLib.SQL.Snapshot to return Results from External SQL Stored Procedures or Query's. The same EnsLib.SQL.Snapshot context variable is used for many of these calls within a BPL. 

Is there something we should be doing at the end of the BPL to ensure that EnsLib.SQL.Snapshot gets cleaned up and purged from Ens.AppData?
