Why metrics monitoring?

But, we need a way to look into an inside of the system

Traditional way:

• vmstat

• iostat

• mysqladmin ext -i15 -r

• (demo on a live system)

What about history or charts?

• There should be a better way

Percona Cloud Tools

Metrics monitor – Why ?

• To Make DBAs or MySQL users more efficient

• Not to automatically predict a behavior 1000+ servers, but:

• To give a comprehensive overview of the system that a DBA works with, so:

• They can make an educated, based on data, decision

• That is an incredibly useful even a DBA has only a couple of servers
