Your database is running. But is it really running well?

You check your application logs. Everything seems fine. Your users aren't complaining. But deep down, you know you're flying blind. You have no idea if:

• Your queries are getting slower over time
• Your connection pool is about to hit the limit
• Your disk I/O is becoming a bottleneck
• Your replication lag is growing

In the old days, you'd cobble together a monitoring solution: install Prometheus, configure Grafana, write custom exporters, set up alerting rules. Weeks of work, and you'd still miss critical metrics.

Filess.io solves this by providing Percona Monitoring and Management (PMM) out of the box on all Dedicated Runtime databases.

You're debugging a critical bug in the Example App. You need to see the raw data in the sale table to understand why the totals aren't adding up.

You fire up TablePlus or DBeaver, but you hit a wall. The database is (rightfully) in a private network.

How do you get in?

Do you temporarily open port 3306 to the world? Dangerous. Do you deploy a VPN server just for this? Expensive.

The answer is an SSH Tunnel.

It's 2:00 AM. Your alarm goes off.

Why? Because the Example App needs more RAM to handle the upcoming holiday traffic, and you have to manually resize the database server during the "low traffic" window.

You groggily open your laptop, SSH in, stop the service, resize the VM, restart the service, and pray it comes back up.

This is the "old way" of operations. It burns out engineers and risks human error.

Filess.io fixes this with automated Maintenance Windows.

Your Example App store is growing. You have thousands of customers, which means you have thousands of emails, addresses, and purchase histories.

But there's a problem. Your database port (3306) is open to the entire internet.

Any script kiddie with a port scanner can find your server, start brute-forcing passwords, or exploit a zero-day vulnerability.

You need to lock it down, now.

It's Black Friday. Traffic is peaking on our Example App e-commerce store. You're monitoring the sales dashboard, and everything looks great.

Then, disaster strikes.

A developer, intending to clean up some test data, accidentally runs a DELETE command on the production database.

DELETE FROM sale WHERE id > 1000; -- Forgot the WHERE status = 'test' clause!

Poof. Hundreds of real customer orders just vanished. The phone starts ringing. The CEO is walking towards your desk.

In the old days, this would be the start of a very long, very bad night. But with Filess.io, it's just a 2-minute fix.
