How do you deal with fragmented performance monitoring across tools?

Question

I’ve been thinking about how performance monitoring tends to spread across a bunch of tools:

1. PageSpeed scores in one place
2. Uptime in another
3. Performance budgets in a spreadsheet
4. Alerts split between email, Slack, and different dashboards

Each tool does its job, but getting a clear picture means jumping between tabs and tools. Context switching eats time, and issues can slip through the gaps between tools.

Questions:

• How do you currently handle performance monitoring when you’re using multiple tools?
• Do you have a single “source of truth,” or do you accept that you’ll always be piecing things together?
• What’s your biggest pain point: alert fatigue, report assembly, or something else?
• Have you found any workflows or setups that actually reduce the fragmentation?

Curious how others deal with this.
