XorMon is an open-source, on-premises alternative or complement to IBM Storage Insights for FlashSystem and Storwize monitoring. It monitors IBM block storage next to other storage vendors, SAN switches, servers and IBM Power in one platform. IBM Storage Insights remains IBM's cloud service for support workflows. This page shows when to use each, or both.
XorMon and IBM Storage Insights often complement each other. IBM describes Storage Insights as an IBM Cloud software as a service offering, available at no cost if you own IBM Block Storage, with support features such as Health monitoring - Call Home events; Automated log collection (ibm.com, checked 2026-11-03). XorMon runs on-premises and monitors IBM block storage with the rest of your infrastructure. The sections below show which tool does which job.
Last updated: November 3, 2026. We review this comparison at least once a year, and whenever IBM or XorMon changes its core positioning.
