Why Off-the-Shelf Monitoring Tools Struggle at Enterprise Scale
Most enterprise teams already run a monitoring tool. The problem shows up later, once the vendor's data model doesn't match your architecture, real-time monitoring software becomes difficult to adapt, alert volume outpaces the team's ability to triage it, and the monthly bill scales with your own traffic instead of your budget. More alerts isn't more insight.
None of that shows up in the sales demo. Dashboards need workarounds once your architecture doesn't match the vendor's assumptions, integrations need middleware to bridge protocol gaps, and the pricing curve tends to punish the exact growth the tool was bought to help you manage.
