Site24x7 is a cloud platform and it automates monitoring by raising alerts if problems are detected.

Site24x7 Infrastructure provides monitoring for many other assets apart from Postgres databases. The system also watches the activity on the servers that host the database. This means that the processes that run the database instance are tracked and so are the server resources that those processes are going to call upon.

The ability to watch server capacity utilization provides quick root cause analysis if the Postgres instance suddenly slows its responses or seems to hang. This could be due to server resource shortage and if that is the case, the server monitor will have already raised an alert. This means that you don’t waste time investigating what is going on with your database when the real problem lies elsewhere.

The tool also provides network monitoring. Again, this lets you know immediately if there is a problem with the route between your database’s server and the users of the system. It could be that slow responses are due to the network and not either the server or the database, so this full-stack monitoring cuts out investigation time.

Who is it recommended for?

The Infrastructure plan is sized and priced for small businesses. Larger businesses pay for capacity expansions to get a service that provides suitable monitoring throughput. This is a cloud platform that can track assets on multiple sites in the same account and there is also a version for managed service providers.
