Apache Solr is an open source enterprise search service from the Lucene project. Solr is written in Java and runs as a standalone full-text search server within a servlet container such as Tomcat.
Like any service or component in your architecture, you’ll want to monitor it to ensure that it’s available and gather performance data to help with tuning.
In this post, we’ll look at how we can monitor Solr, what performance metrics we might want to gather and how we can easily achieve this with Opsview.

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 »

Opsview Community 3.11 - Free distributed monitoring
One of Opsview’s great features is distributed monitoring, which we’ve had for over 5 years now.

We do all the system integration work, so you don’t have to.

We’ve just fixed a bug in Nagios® which an Opsview user had raised to us. A change made to Nagios in version 3.2.2 caused an issue where service alerts were being raised in the nagios.log file for every result that came back from a host that was down. This had the impact of adding lots of extra alerts that were overwhelming Opsview’s event views.

So, what’s up in the Opsview’s world?
We’re comparing APIs. A user was asking how Opsview’s API compares to Icinga’s API. We spent a bit of time investigating what the competition are up to.

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).

Ok, so you’ve decided that you want to use Hudson to build your Grails projects (or have read part 1 and want to use CodeNarc too). If you don’t know where to start, you’ve come to the right place.
