It draws\none pane per device and one cell per slice of the address space, green for\nreads, red for writes and amber for TRIM, so a resilver or a scrub shows up\nas a bright head marching across the map while scattered metadata writes\nspeckle it.\n\nEach cell carries an activity layer that fades in milliseconds and a dimmer\ntrail that fades over a minute, showing both what the disk is doing now and\nwhere the head has been.\n\nIt needs root, and on FreeBSD it needs the DTrace modules loaded\n(kldload dtraceall). A demo mode draws synthetic devices without root.","flavors":[],"html":"https://daemonports.org/dragonfly/sysutils/blockio/","kind":"port","lastUpdate":null,"license":["BSD2CLAUSE"],"licenses":["BSD-2-Clause"],"maintainer":"olgeni@FreeBSD.org","name":"blockio","newest":false,"newestVersion":"1.3.1","noVulnData":false,"origin":"sysutils/blockio","otherSystems":[{"maintainer":"olgeni@FreeBSD.org","newest":true,"origin":"sysutils/blockio","path":"/sysutils/blockio/","system":"FreeBSD","updated":"2026-11-11","version":"1.3.1_1"},{"maintainer":"olgeni@FreeBSD.org","newest":true,"noVulnData":true,"origin":"sysutils/blockio","path":"","system":"HardenedBSD","version":"1.3.1"},{"maintainer":"olgeni@FreeBSD.org","newest":true,"noVulnData":true,"origin":"sysutils/blockio","path":"","system":"GhostBSD","version":"1.3.1"}],"packages":null,"pkgName":"blockio-1.3.0_2","related":null,"repository":"DPorts","requiredBy":[],"requiredByCount":0,"runDepends":[],"status":null,"system":"dragonfly","systemLabel":"DragonFly","version":"1.3.0_2","versions":[{"date":"2026-11-11","version":"1.3.0"}],"vulnerabilities":null,"www":"https://github.com/olgeni/blockio"}
