This milestone's outputs will be the monitoring of the whole system. It will involve monitoring and alerting at different levels: underlying servers, running systems, database usage.

Server monitoring:

We will monitor CPU, I/O, disk and memory for every server, setting up relevant alerts for unexpected usage levels,

Running systems:

We will monitor process health and uptime

Database usage:

We will monitor typical database metrics (replica lag, queries) as well as db-sync related metrics (eg. block height lag).

• Monitoring and dashboards in place
• test alerts delivered
