In my opinion it makes a lot of sense. Not just for passive checks either. For instance with many of the Log4* implementations out there one can do almost anything with the appenders including turning them into JMS messages. Maybe not the best example but you get my drift. As messaging is fast becoming (if it isn't already) a standard thing in the world of corporate applications adding messaging to Nagios brings the two a little bit closer. </pre> </blockquote> <pre wrap=""> Before you get going implementing something like this, please consider why micro-kernels have never been a hit; Messaging systems, and especially generic ones that can carry pretty much whatever, come with a huge performance penalty. Try using a message queue for real-time 3d rendering and you'll quickly see why it doesn't work. </pre> <blockquote type="cite"> <pre wrap="">I also see possebilities for active checks as I mentioned. Especially with check distribution systems as seen in DNX. </pre> </blockquote> <pre wrap=""> What has DNX got to do with it? It already sends its checks back to Nagios without fiddling with message queues. </pre> <blockquote type="cite"> <pre wrap="">Other benefits are that EMS systems are easier to tunnel through things like firewalls and have often got clustering abilities too. </pre> </blockquote> <pre wrap=""> That's pure and utter bullcrap. I'm curious who gave you the notion that firewalls care about application layer protocols. It'd be interesting to know so I can ask them for advice and then do the exact opposite. </pre> <blockquote type="cite"> <pre wrap="">The only downside I see is that it is an extra application to install and manage and depending on your choice is possibly a commercial application. Then again I am guessing many corporations already have an EMS. </pre> </blockquote> <pre wrap=""> Unless you mean "many = the majority", this solution is nowhere near interesting enough, imo. Otoh, go wild and hack it up. I'll get you some hosting for it if you like, and when you have something to test, I'll chuck it over to our QA team. </pre> <blockquote type="cite"> <pre wrap="">And also as you mention most EMS have JMS support which would make the whole thing vendor agnostic (nice term). Where needed one could always use things like stomp to go even further in the abstraction. </pre> </blockquote> <pre wrap=""> One question though; Why would we want to start tinkering around with Java in Nagios? Windows' poor fork() support already makes the plugins unusable under Windows unless you completely re-design the entire core engine, and it's written in sufficiently portable C to work on 99.9% of all unix systems where people actually still install new software (or upgrade old one, for that matter). </pre> </blockquote> <div class="moz-signature">-- <title>OpSign</title> __________________________________________________ <table border="0" cellpadding="0" cellspacing="0" width="350"> <tbody> <tr> <td valign="top" width="130"> Alessandro Ren </td> <td valign="top" width="220"> OpServices Luciana de Abreu, 471 - Sala 403 Porto Alegre, RS - CEP 90570-060 </td> </tr> </tbody> </table> <table border="0" cellpadding="0" cellspacing="0" width="350"> <tbody> <tr> <td valign="middle" width="180"> ( phone 55(51)3275-3588 4 fax 55(51)3275-3588 </td> <td valign="middle" width="200"> Q mobile 55(51)8151-8212 : email <a href="mailto:%22alessandro.ren@opservices.com.br%22">alessandro.ren@opservices.com.br</a> </td> </tr> </tbody> </table> __________________________________________________ </div> </body> </html>
