XorMon by Xorux: enterprise infrastructure monitoring
XorMon in short

What is XorMon?

LPAR2RRD and STOR2RRD are legacy tools. XorMon is their full-stack successor, and all new development goes into XorMon. XorMon is an open-source (GPL v3), on-premises infrastructure monitoring platform for servers, virtualization, storage, SAN, LAN, backup, tape, databases, cloud and containers, built by Xorux, an independent software company based in the Prague area, Czech Republic (registered office: Babice). The supported technologies are listed on the Technologies page.

Who we are

A monitoring vendor that has been here for 13 years, and intends to stay.

Xorux was founded in October 2013 by Pavel Hampl, a UNIX systems engineer with thirty years of administration experience, working for UBS bank or IBM, where he designed high-availability and disaster-recovery architectures for IBM Power Systems. The company was built around LPAR2RRD, the open-source IBM Power Systems performance monitor he had been developing since 2007, today part of the XorMon, LPAR2RRD and STOR2RRD family.

Since then, Xorux has grown organically: no venture capital, no acquisitions, no debt.

Independence is not a marketing position for us. It is the reason our customers can plan five-year infrastructure roadmaps with our software on them, without worrying that an acquirer will deprecate the product, change the licensing model, or move the engineering team to a different project.

IBM heritage

Built first for IBM Power Systems. Trusted by the largest IBM environments in the world.

Xorux was founded by a former IBM Power Systems engineer who spent six years inside IBM designing high-availability and disaster-recovery architectures before launching the company. Our first product, LPAR2RRD, was released in 2007 to address a gap that IBM tooling did not cover at the time: long-term performance history and capacity planning across LPAR boundaries.

19 years later, we still ship deeper IBM Power Systems and IBM Storage coverage than any general-purpose monitoring platform. From AIX and VIOS to FlashSystem, DS8000, Storage Protect (TSM), Spectrum Virtualize and many others. If it carries an IBM logo, it almost certainly has a native integration in our products.

That heritage is why XorMon is found in the data centres of major European and North American banks, insurers and government agencies running mission-critical IBM Power Systems workloads.

How we operate

Three commitments to every enterprise customer.

These are the practical reasons procurement and architecture teams approve XorMon for mission-critical environments.

01 · Continuity
Vendor stability you can plan around.

Profitable since the first year, debt-free, founder-led. We are not looking for an exit and we are not running out of runway. Our roadmap horizon is measured in years, not funding cycles.

02 · Support
Senior engineers on the support line.

Tickets are answered by the engineers who write the product, not by a generic helpdesk. Average tenure on our support team exceeds eight years. SLA-backed contracts available worldwide.

03 · Sovereignty
Your data stays on your network.

XorMon deploys entirely on-premises. No telemetry leaves your environment, no SaaS dependency, no third-party processing. Source code is available under GPL v3 for audit and inspection.

In production

Used in mission-critical environments worldwide.

XorMon, LPAR2RRD and STOR2RRD run inside UBS, IBM, Adobe, Pfizer, Generali, Nomura, First Abu Dhabi Bank, Citizens Financial Group and ten thousand more organizations across 66 countries.

Questions

Frequently asked questions

What is XorMon?

XorMon is an open-source (GPL v3), on-premises infrastructure monitoring platform for servers, virtualization, storage, SAN, LAN, backup, tape, databases, cloud and containers.

Who makes XorMon?

XorMon is built by Xorux, an independent, privately held, founder-led software company based in the Prague area, Czech Republic (registered office: Babice), founded in 2013.

Is XorMon the same as LPAR2RRD?

No. LPAR2RRD (first released in 2007) and STOR2RRD are legacy tools. XorMon is their full-stack successor: a separate platform that can run alongside them on the same devices during a migration, and all new development goes into XorMon.

What is the relationship between XorMon, LPAR2RRD and STOR2RRD?

LPAR2RRD (servers, virtualization, cloud, containers and databases) and STOR2RRD (storage, SAN and LAN) are legacy tools from the same company. XorMon is their full-stack successor, and XorMon Original was a first-generation front-end above both.

What is XorMon NG?

XorMon NG (XorMon Next Generation) is the former name of XorMon. It was announced as XorMon Next Generation in 2024 (release candidate 0.9.12 on 11 April 2024, version 1.0.0 on 25 April 2024) and renamed XorMon with version 2.0.0 on 2 October 2025.

What is the difference between XorMon and XorMon NG?

There is no difference in product: XorMon NG is the former name of XorMon. The name changed with version 2.0.0 on 2 October 2025.

What is the difference between XorMon and XorMon Original?

XorMon Original is the first-generation front-end that unifies LPAR2RRD and STOR2RRD instances in one interface; it is not the current platform. XorMon is the current full-stack successor, and new users should start with XorMon.

Can I migrate from LPAR2RRD to XorMon?

Yes. Device definitions can be exported from LPAR2RRD and STOR2RRD and imported into XorMon, XorMon can run alongside the legacy tools on the same devices, and existing installations can be kept for historical data. The existing support contract of Enterprise edition customers of the legacy tools covers XorMon for the same environment size, at no extra fee.

Is XorMon free?

Yes. XorMon, LPAR2RRD and STOR2RRD are released under the GNU GPL v3 and are free to download, inspect and run in production, with no registration and no time limit. The free edition has limits per device type, which the Enterprise edition removes.

What license is XorMon released under?

XorMon is released under the GNU General Public License version 3 (GPL v3), like LPAR2RRD and STOR2RRD.

Is XorMon cloud-based or on-premises?

XorMon deploys entirely on-premises, with no SaaS dependency.

Does XorMon support IBM i?

Yes. XorMon runs a C-language OS agent on each IBM i partition that collects CPU, jobs, memory pools, ASP storage, disk and LAN data and sends it to the XorMon server. IBM i partitions on IBM Power are also covered through the HMC REST API.

Does XorMon support IBM Power and AIX?

Yes. XorMon collects data from IBM Power servers through the HMC REST API for AIX, IBM i, VIOS and Linux on Power LPARs, and adds OS metrics from agents in AIX, VIOS and Linux on Power LPARs.

Which technologies can XorMon monitor?

XorMon monitors IBM Power Systems (AIX, IBM i, VIOS, Linux on Power, HMC), VMware, Nutanix, Kubernetes, SAN, storage, LAN, databases, backup, tape, cloud and mainframe.

Is there a free trial?

Yes. A three-month trial licence with no restrictions is included with the installation package.

Does one support contract cover XorMon, LPAR2RRD and STOR2RRD?

Yes. A single support contract covers the entire Xorux product family, XorMon, LPAR2RRD, STOR2RRD and XorMon Original, at no additional charge.

Who uses XorMon?

More than 10,000 organizations in 66 countries use XorMon, LPAR2RRD and STOR2RRD; customers named on the Customers page include UBS, IBM and Pfizer.
