Proby - Task monitoring made simple
Hello HN. We were occasionally running into issues where our scheduled tasks would not start when expected. There were many reasons for this (environment changes, lock files not being cleaned up properly, etc). So, we created a simple application to monitor our scheduled tasks, and notify us if they didn't start or finish when expected. Now we're notified immediately (via email or SMS) when a scheduled task isn't kicked off when it is supposed to. The app also keeps track of the run times for past task executions, which has been useful in tracking down unexpected changes in task run times.…

In plain words
Proby is a task monitoring application that tracks scheduled jobs and alerts users via email or SMS when tasks fail to start or finish as expected. It records execution times across job runs to help identify performance anomalies and diagnose issues caused by environment changes or system problems. Designed for teams managing automated scheduled tasks, Proby provides immediate notification of failures so issues can be addressed quickly rather than discovered later through manual checks.

Appstat – Process Monitor for Windows2025 · pragmar.com · ▲86Hey HN, I made a Windows process monitor for app developers and advanced end users. I wanted a taskmgr system-level graph view per app. Windows procmon, while capable, has always been tedious to set up (esp. if not used often). That's pretty much the whole idea behind the app--to simplify app-level monitoring, to make it easy. I hope some of you find it useful!
