First, I would like to invite you to my webinar, “Monitoring All (Yes, All!) MySQL Metrics with Percona Cloud Tools,” on Wednesday, June 25 at 10 a.m. Pacific Daylight Time, where I will talk on the
new features in Percona Cloud Tools, including monitoring capabilities.
Basically our agent allows users to collect ALL MySQL metrics plus important environment’s metrics, like CPU, memory, IO stats.
And when I talk all MySQL it is:
So you see we collect more than 1000 points. We collect data every second, aggregate per minute and it becomes available with a 1-minute resolution, but with descriptive stats like min, max, avg, median, 5%-percentile, 95%-percentile of collected data. We found this represents data better than 1-sec points, which can be a quite noisy.
Please note you can see a value at any point in the past. We even can go to week range and see values several days ago
You can choose a custom timerange back to hours, days, weeks, etc with zoom-in capabilities.
Averaging metric smooths the line, and really hides the problem, while with min we are able to see that throughput drops to zero, that means that during some seconds the server did not execute any queries (which is essentially stalls)
More about the agent.
Our percona-agent is open source. This is our way of sharing our Go knowledge, and also you can check that we do not do anything insane on your server (like bitcoin mining or black magic regression modeling math).
What is also interesting about our technology is that we use a permanent connection (based on WebSockets technology, so it looks like a connection to web browser) between an agent and our servers. This way
we support a bi-directional real-time communication between https://cloud.percona.com/ and an agent.
That means you can manage an agent and receive data updates at the same time. Pretty cool, yeah?
Our agent comes with “minimal efforts” in mind.
The goal of Percona Cloud Tools is to provide you with FULL visibility on what’s going on inside your system right now or at some point in the past, and to gain additional insights on your database server.
Our tools are useful not only if you have hundreds of database servers to manage, but pretty much for single installations, too. Well, of course, we always can run
mysql -e "SHOW GLOBAL STATUS" , vmstat 10 ; iostat -dxm 10 manually when we need to troubleshoot something, but is it not useful to collect all this data automatically and be able to go to any point in the past?
You can register for the Beta right now. No invitation is needed, but it may take sometime for us to activate your account, we see a quite a demand right now and we need to prime our servers.
And what’s important, eventually our tools will require a payment, but we will always provide a free level, which will be useful enough for small accounts (this is not a bait-and-switch 30-days trial approach).
