iotop vs OpenProcMon
Both stand on process monitoring software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan Linux
iotop offers configurable process-level I/O monitoring for Linux, including batch output and filters. Its root requirement and lack of remote monitoring or process alerting may matter for some users.

OpenProcMon offers real-time monitoring, .PML compatibility, and developer-facing tools at no cost. Check the 64-bit Windows requirement and elevated-privilege requirement for live capture before choosing it.
