Case Study: The Python Script That Caught Two Dying Drives in Weston
A company in Weston was doing server health checks the way most small IT environments do: someone logs in, eyeballs disk space, glances at services, moves on. It consumed an estimated ten hours a week and still missed things, because human eyes check occasionally while failures develop continuously. The fix was not a monitoring platform with agents and license fees. It was a small Python script that checked the boring things every hour and stayed silent unless a threshold was crossed.

- Scope
- Scheduled server checks and health alerts
Where it stands: The script ran quietly for months and paid for itself twice: once in the estimated ten hours a week of manual checking it ended, and once on the morning it flagged two degrading RAID drives while they were still replaceable on a schedule.
The challenge
- Manual health checks consuming roughly ten hours of staff time every week across the server fleet.
- Failures that develop between checks: a disk filling overnight, a service dying on Friday evening, SMART errors climbing quietly inside a RAID array.
- No budget or appetite for a full monitoring platform, its agents, and its per-node licensing.
What we built
Hourly telemetry checks
A Python script checked capacity, memory, critical services and backup freshness on a schedule. Drive-health collection depends on the operating system, storage controller and tools available on the host.
Silence as a feature
The script reported nothing when everything was fine. No daily digest to ignore, no dashboard to forget. The first message anyone saw was the one that mattered.
Webhook alerts to where people actually look
When a threshold was crossed, the alert arrived in the team chat within the hour, with the specific metric and machine, not a vague red light.
Drive health included in the checks
Drive-health readings were reviewed as part of the scheduled checks, flagging deteriorating readings on two RAID drives.
The results
- Two degrading drives were flagged roughly two days before they were replaced. This is the time before replacement, not a prediction of the exact time they would have failed.
- The client estimated that the routine had taken about ten staff hours each week.
- The script covered specific health checks without a recurring monitoring-software license. Maintenance and response still required engineering time.
Client not named by policy. The hours figure is the client’s own estimate of the manual routine this replaced. A new, cleaned up implementation of this script is being prepared for public release; the story above describes the original production version.
