Section 3 of 6 Business case
Maintenance
Logging that depends on discipline decays. Methods get renamed, parameters change, a junior skips the try/catch log, and six months later production is quieter than it should be — until it fails.
Why hand-written logs rot
A log line is a second implementation of the method. It drifts. ArgusLogs records the real method: name, parameters, return, exception, duration.
- Refactors drop log lines. The compiler does not care. Customers do, on the next outage.
- Copy-paste logs lie — wrong id, stale message, no duration.
- “We will add logging in the next sprint” is how dark modules stay dark.
What stays light as the team grows
Maintenance effort is what you carry after go-live. ArgusLogs keeps that effort flat: the weaver follows the assembly. You do not staff a logging cleanup programme.
- Same pattern in every service. Reviews look for [LogMethod], not a style of string templates.
- Contractors and new squads cannot “forget observability” on a feature branch as easily.
- You can raise or lower detail in one place instead of hunting 400 LogInformation calls.
- Less code to own: telemetry is not mixed into pricing, checkout, and billing methods.
- Safer changes: you are not editing the money path just to add a log.
- Clearer ownership: platform sets the weaver; product teams ship features.
