Freeware IT monitoring tools are used by thousands of organisation worldwide however using them to monitor complex network, server and application installations can be quite a challenge. This blog post takes the basic capabilities of one such tool, Nagios® Core, and shows how you can scale it with Opsview for use in enterprise environments.
If you’re managing any web sites or web applications Selenium can be used with Opsview’s monitoring platform to ensure your customers get the very best user experience and increase your online conversion rates. Continue reading »
Hindsight is a wonderful thing.
In hindsight, Opsview would have always had access controls for objects at the role level – since roles also define which parts of the Opsview application you can get to, it would make sense to also put all the host and service objects into this definition.
(In our defence, we wanted to make it as obvious as possible for a contact when you were changing access information.)
The downside of our design decision many years ago is that Opsview administrators who have lots of their users – or contacts in Opsview terms – with the same sort of access and were having to change each user individually. This was painful and error prone if you had 40 “similar” users. Continue reading »
We present the 2nd part to our Catalyst advent calendar entry about internationalising your Catalyst application, complete with some really neat scripts such as automatically translating your string using Google! See it here. Enjoy!
The JNRPE server provides an open source Java implementation of the Nagios Remote Plugin Executor (NRPE). This is much more efficient for performing JMX checks than regular NRPE as you only need to start one JVM rather than a JVM instantiation per check (as performed by check_jmx invoking java -jar JMXQuery.jar).
Since Grails incorporated the testing plugin into core it provides good unit & integration testing support (via the test-app script). There are also additional plugins to support BDD tools (e.g. EasyB) and functional testing (e.g. Canoo WebTest).
The first part of a series of posts on Grails and Hudson leading up to a presentation at the London Groovy & Grails User Group. Subsequent instalments will include testing (unit, integration, functional), test coverage, automatic war deployment and monitoring Hudson with Opsview Enterprise.
This post is based on research we’ve undertaken to develop a pilot mash-up style, charting dashboard for our monitoring solution, Opsview Enterprise. However the concepts we discuss could be used when building a dashboard that displays information from many other enterprise solutions. The assumption we make is that the reader is familiar with Java and the Google Web Toolkit (GWT). For more information about GWT and the other libraries used in this blog please see the Resources section at the end. Continue reading »
