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.

Not all open source IT monitoring systems are made equal. Just as IT infrastructures vary according to the size, location and type of business, so the systems that monitor and report on their performance must be flexible, easy to scale and configure to meet the demands of an ever changing business.
Opsview gives you the edge with open source monitoring by offering an easy to install and configure system that delivers enhanced functionality in a highly scalable, commercially supported system.
If you’re replacing your existing monitoring solution, or evaluating systems for implementation, here are 10 reasons why you should consider Opsview:

Setting up distributed monitoring in mission critical production environments is a complex task; configuration can be challenging and mistakes costly. Opsview Enterprise edition and Opsview Syncmaster module make deploying an enterprise monitoring system easy and reduce the risks associated with migrating configuration objects from development to production environments. Here’s how: Continue reading »

So you followed the steps in the previous post about enabling SNMP traps on ESX4. Now you probably want to pick those up by something useful. Opsview can be configured to handle the traps quite easily. Just follow the steps below and your server will be listening to those pesky traps. After that, you’ll need to write a couple of service check handlers in Opsview to make sense of the traps. More on that later. This post is just about picking them up. Continue reading »

This post outlines how to get SNMP traps from ESX hosts and monitor them in Opsview. The first part deals with configuring SNMP traps to get them working correctly with ESX hosts, part 2 tells you how to monitor them with Opsview.
The following steps worked on ESX 4.1. Depending on versions you may have different results. For simplicity, I used 10.0.0.1 as IP for my ESX host, and 10.0.0.99 for my SNMP trap handler. Continue reading »

Alerts happen. They are the reason why monitoring applications were created: to alert us when servers need attention. The difference between an effective network monitoring system and an annoying one is a fine line between information and noise. Alerts should be descriptive and prompt an administrative action, not elicit a huff of frustration. Here are a few ways to keep your Opsview installation (and you) effective and relevant in your company. Continue reading »

Over the last couple of years we have seen an increase in port-density on server-hardware and currently the quad-nic (4 port network interface card) seems to be the standard. These cards allow for some great features like bonding (on *nix) or nic-teaming (on Windows) where multiple interfaces are bundled together or setup as fail-overs. It also allows you to nicely split your networks into multiple segments like management and production with each network connected over dedicated NICs as shown below…

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.

Many freeware IT monitoring tools are great but using them to manage complex systems can be a real challenge. It can also be unforgiving on anyone less than expert in configuring the system with mistakes being punished by a complete stop in monitoring activity.

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 »
