Working on mycheckpoint, I have the intention of adding custom monitoring. That is, letting the user define things to monitor. I have my own thoughts, I would be grateful to get more input! What would the user want to monitor? Monitoring for the number of SELECT statements per second, InnoDB locks, slave replication lag etc. [...]
I’m having my usual fun with charts. Working on mycheckpoint, I’ve generated monitoring charts using the Google Chars API. But I’ve also had chance to experiment and deploy interactive charts, JavaScript based. In particular, I used and tweaked dygraphs. I’d like to note some differences in using charts of both kinds. And I think it [...]

I’ve hit a recent change which took me by surprise. I was used to checking for the ‘questions‘ global status variables to see the total amount of queries the server performs. So, for example, I could run com_select/questions to learn the SELECT ratio out of all queries. Apparently, as of 5.0.72-5.0.76 & 5.1.31 this has [...]
mycheckpoint (see announcement) allows for both graph presentation and quick SQL access to monitored & analyzed data. I’d like to show the power of combining them both. InnoDB performance Taking a look at one of the most important InnoDB metrics: the read hit ratio (we could get the same graph by looking at the HTML [...]
