My MySQL SNMP Agent
+1 Vote Up -0Vote Down
Back in February I wrote an article titled A Small Fix For mysql-agent. Since then we did a few more fixes to the agent and included a Bytes Behind Master (or BBM) chart. For those who can't wait to get their hands on the code, here's the current version: MySQL SNMP agent RPM. For those who'd like to learn about it's capabilities and issues, keep reading.

What to Expect From this Version


The article I quoted above pretty much describes the main differences with the original project, but we went further with the changes while still relying on Masterzen's code for the data collection piece.

The first big change is that we transformed

A Small Fix For mysql-agent
+1 Vote Up -0Vote Down
If you're already using an SNMP monitoring tool like OpenNMS, mysql-agent is a great way to add a number of graphics using Net-SNMP. However mysql-agent has a small bug that drove me crazy. I will try to highlight the process on how I discovered it (and hence fix it) since it involved learning about SNMP, how to diagnose it and eventually, once all the pieces came together, how simple it is to write your own agents.

Although versions are not that important, just for the sake of completeness we were using CentOS 5.5, MySQL 5.5.8 Community RPMs, Net SNMP version 5.3.22 and OpenNMS Web Console 1.8.7.

The Problem

Cloud monitoring keeps open source in cool crowd
+0 Vote Up -0Vote Down

One of the first special reports I wrote for 451 Group was an analysis of the open source systems management vendors on the scene — GroundWork, Hyperic, Zenoss, OpenNMS Group, Nagios Enterprises and some others. These named ones are those that made it and while there was some reckoning in the market and there have been changes, it is interesting to see these players still plugging away, pushing into new markets and powering open source for systems, network and application monitoring and management, including cloud computing environments.

When acquired by SpringSource a year ago, there was some question as to the real value of open source systems monitoring and management

Dual of denial, on the success and failure of dual licensing
+1 Vote Up -0Vote Down

There’s been a fair amount of attention – both positive and negative – on dual licensing in recent weeks. A few days ago Brian Aker wrote: “The fact is, there are few, and growing fewer, opportunities to make money on dual licensing.”

It is a sweeping statement, but one that is worth further consideration, especially since, as Stephen O’Grady noted it is directly contradicted by Gartner’s prediction that: “By 2012, at least 70% of the revenue from commercial OSS will come from vendor-centric projects with dual-license business models.”

Success?

mysql-snmp 1.0 – SNMP monitoring for MySQL
+1 Vote Up -0Vote Down

I’m really proud to announce the release of the version 1.0 of mysql-snmp.

What is mysql-snmp?

mysql-snmp is a mix between the excellent MySQL Cacti Templates and a Net-SNMP agent. The idea is that combining the power of the MySQL Cacti Templates and any SNMP based monitoring would unleash a powerful mysql monitoring system. Of course this project favorite monitoring system is OpenNMS.

mysql-snmp is shipped with the necessary OpenNMS configuration files, but any other SNMP monitoring software can be used (provided

Introducing mysql-snmp!

Thanks to Days of Wonder the company I work for, I’m proud to release in Free Software (GPL):

mysql-snmp – monitor a MySQL server with SNMP

History

At Days of Wonder, we’re using MySQL for almost everything since the beginning of the company. We were initially monitoring all our infrastructure with mon and Cricket, including our MySQL servers. Nine months ago I migrated the monitoring infrastructure to OpenNMS, and at the same we lost the Cricket MySQL monitoring (which was done with direct SQL SHOW STATUS LIKE commands).

I had to find another way, and since OpenNMS excels at SNMP, it was natural to monitor MySQL through

Define “open source vendor”
+0 Vote Up -0Vote Down

I received an email from Tarus Balog, CEO of OpenNMS Group, on Friday, taking issue with the language I had used to describe two open source vendors (and I use that term deliberately).

Essentially Tarus objected to me using the term “open source vendor” to describe two companies with Open Core licensing strategies. His email raises a valid point about how we determine which companies are considered “open source vendors” and I wanted to use the opportunity to outline the rules I use to make that decision.

As a technical snafu at our end had prevented Tarus from leaving a comment on the blog I hope he won’t mind me using his words to explain the issue he raised.

    OpenNMS JDBC Stored Procedure Poller with MySQL
    +0 Vote Up -0Vote Down

    Since a few months we are monitoring our infrastructure at Days of Wonder with OpenNMS. Until this afternoon we were running the beta/final candidate version 1.5.93.

    We are monitoring a few things with the JDBC Stored Procedure Poller, which is really great to monitor complex business operations without writing remote or GP scripts.

    Unfortunately the migration to OpenNMS 1.6.1 led me to discover that the JDBC Stored Procedure poller was not working anymore, crashing with a NullPointerException in the MySQL JDBC Driver while trying to fetch the output parameter.

    In fact it turned out I was plain wrong. I was using a MySQL PROCEDURE:

    DELIMITER //
    CREATE PROCEDURE `check_for_something`()
