Do we want an Open Source MySQL Monitoring tool ?
Matt Reid wants to know what we want in an Open Source MySQL monitoring solution ?
He is working on the second incarnation of Monolith and wants input from the MySQL community.
Now for me the bigger question is if we want an isolated tool that runs stand alone, or a tool which we can integrate it in something we already have.
To me there is a difference between a tool that I want to use to debug my environment, such as Mytop or MySQL Activity Report, in that case I need some tool that quickly installs with little dependencies and little impact.
On the other side I want a tool that is constantly there, that tells me about trends and performance history. But there I don't want an isolated toool, I want something fully integrated where I can correlate different measurements from disk io, memory usage etc , that tool should also tell me about the things that go
We did some research earlier this year to figure out the current state of Open Source monitoring tools. Different tools have a different audience.. some go for the network layer, others take the os level and other even try to go deep inside the applications.
Given that knowledge we even had the idea to refocus that research comparing different monitoring tools such as Zabbix, Zenoss, Hyperic and Nagios again but this time with a focus on monitoring MySQL and submit that as an abstract for the upcoming MySQL conference, we didn't .. maybe next time.
There's plenty of frameworks already that will allow you to send alerts on all of the occasions you list, or allow you to graph all the values you want. And yes we want to see those values too.
But do we want yet another tool , yet another URL to browse to or do we want those alerts and graphs integrated in an existing tool such as Zabbix, Zenoss or
Hyperic .. I guess I prefer the integrated approach.
