There are many cool, new things happening withPercona Cloud Tools. To avoid “tl;dr” I will highlight only one new feature after a brief, general announcement. The new feature is a 3-minute MySQL monitor. I’ll blog later about other features.
The general announcement is: Last week we quietly released a brand-new agent calledpercona-agent, and we added MySQL and system monitoring to Percona Cloud Tools. We also wrote a brand-new API from the ground up. We call it all “PCT v2″. For you it means a better experience and more features, all still free while we’re in beta.
One new feature in Percona Cloud Tools v2 is MySQL monitoring in 3 minutes, i.e. a 3-minute MySQL monitor. Let’s be honest about monitoring: We know we should but we often don’t. It’s like software testing and other best-practices. AsMonitoramaearlier this month highlighted, the problem is not a lack of sufficiently advanced technology. Products likeGrok demonstrate this. The problem is that setting up a meaningful MySQL monitor can be difficult. The reason is simple: genearl-purpose monitoring solutions leave the user to answer and implement important questions like “which MySQL metrics should we monitor?” To make an analogy: General-purpose monitoring solutions are sledge hammers and MySQL is a nail. You can drive a nail with a sledge hammer, but it’s a lot easier (and probably safer) with a hammer. The 3-minute MySQL monitor in Percona Cloud Tools v2 is a hammer.
The “3-minute” qualifier means that you can download and install percona-agent and have charts with MySQL metrics 3 minutes later. The initial setup is really that quick and easy. Give it a try; it’s free! Justsign up, download percona-agent, and run its install script.
The Percona Cloud Tools MySQL monitor is still new and in development. It cannot replace a general-purpose monitoring solution like Zabbix, and it does not have alerts, but that’s ok because itsraison d’êtreis different: to make monitoring MySQLquick, easy, and meaningful.
We use Percona Cloud Tools internally for our production servers, but we’re developing it for you. (One reason for which percona-agent is free and open-source.) Try it out and let us know what you think, especially if you run into problems. Thanks in advanced, and stay tuned for more blog posts and webinars about Percona Cloud Tools, like Vadim’s upcoming webinar on June 25th: Monitoring All (Yes, All!) MySQL Metrics with Percona Cloud Tools.

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
