  • mycheckpoint, discontinued

    March 6, 2014

    Time to admit to myself: mycheckpoint has to be discontinued. I started mycheckpoint back in 2009, as a free & open source lightweight monitoring tool for MySQL. Over some years it evolved and became an actual (lightweight) monitoring solution, used by many. It has a unique and original design, which, alas, is also its bane. […]

  • mycheckpoint revision 231 released

    A new release for mycheckpoint: lightweight, SQL oriented MySQL monitoring solution.

  • MySQL monitoring: storing, not caching

    February 22, 2012

    I've followed with interest on Baron's Why don’t our new Nagios plugins use caching? and Sheeri's Caching for Monitoring: Timing is Everything. I wish to present my take on this, from mycheckpoint's point of view. So mycheckpoint works in a completely different way. On one hand, it doesn't bother with caching. On the other hand, […]

  • Documentation in SQL: CALL for help()

    January 11, 2012

    Documentation is an important part of any project. On the projects I maintain I put a lot of effort on documentation, and, frankly, the majority of time spent on my projects is on documentation. The matter of keeping the documentation faithful is a topic of interest. I'd like to outline a few documentation bundling possibilities, […]

    March 3, 2011

    This post continues Generating Google line charts with SQL, part I, in pursue of generating time series based image charts.

To date, Google Image Charts do not support time-series […]

  • Generating Google line charts with SQL, part I

    February 1, 2011

    In this series of posts I wish to show how Google Charts can be generated via SQL. We discuss the Google Charts limitations which must be challenged, and work towards a simple chart. I'm going to present the algorithm I use in mycheckpoint, a MySQL monitoring utility, which generates Google charts by raw data using […]

  • openark-kit, Facebook Online Schema Change, and thoughts on open source licenses

    September 16, 2010

    MySQL@Facebook team have recently published an Online Schema Change code for non blocking ALTER TABLE operations. Thumbs Up! The code is derived from oak-online-alter-table, part of openark-kit, a toolkit I'm authoring. Looking at the documentation I can see many ideas were incorporated as well. And of course many things are different, a lot of work […]
