DigitalOcean Monitoring is a free, opt-in service that gathers metrics about Droplet-level resource utilization. It provides additional Droplet graphs and supports configurable metrics alert policies with integrated email Slack notifications to help you track the operational health of your infrastructure.
You cannot revert to basic Droplet graphs after enabling the metrics agent.
You cannot add or change the alert email address for individual accounts.
Alerting is not yet available for load average.
Because the metrics agent focuses on system-level data, it is not suitable for application performance monitoring (APM) tasks like tracking application errors, website connections, or identifying application bottlenecks. These require a monitoring system with a different focus, which could be used in addition to DigitalOcean Monitoring.
