Service limits
Read the current plan in Pricing or the Redis/MySQL/VPS details. Review usage against capacity and choose whether to reduce workload or upgrade before limits regularly affect the app.
Billing
Check hourly/monthly price information where displayed, resource usage and top-up history to understand which workloads create costs. Use the service's actual billing terms.
Logs and metrics
Use logs, metrics, activity and usage together to distinguish application failures, resource pressure and unexpected costs. Repeated retries can worsen a limit problem; investigate the original cause.
