Nagios XI VMware Virtualization Wizard Released

By Troy Lea on October 29, 2014

Nagios Enterprises is excited to announce the release of the VMware Virtualization Wizard for Nagios XI.

The VMware Virtualization Wizard monitors your VMware virtual environment by offloading the VMware checks to a vSphere Management Assistance (vMA) appliance.

This is achieved by utilizing the plugin box293_check_vmware, which has been written specifically for use on the vMA. Troy Lea (the author of box293_check_vmware) received a lot of feedback at the VMworld Conference after giving his talk on the plugin.

Why use the box293_check_vmware plugin? The plugin utilizes the VMware SDK. The SDK is notoriously CPU and Memory hungry, which can easily overload and cripple your Nagios XI host. By offloading the plugin to the vMA appliance, your Nagios XI server will not be affected as you monitor your VMware virtual environment.

The VMware Virtualization Wizard and installation instructions are available for download from the Nagios Exchange.

Monitoring Weblogic Metrics with Nagios XI

By Trevor McDonald on August 28, 2014

Weblogic is a popular Java-based application server that acts as a middleware between the application and the Java environment. It provides a framework for developing traits such as reliability (recovering from failures), scalability (dynamic service scaling) and security (unified security system for apps). Nagios XI has the ability to monitor various aspects of Weblogic using wlsagent as outlined in our document Monitoring WebLogic With Nagios XI. In this post I will expand upon some of those metrics, such as what they mean and why they are important. Links to further reading will be provided where relevant.

Monitoring Apache Cassandra Database Nodes with Nagios XI

By Andy Brist on August 21, 2014

As cloud services grow in popularity, so do the networks that provide those cloud services. Few webserver-based distributed databases are as easy to install and configure as Apache Cassandra. Apache Cassandra is an open source distributed database management system designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure. Cassandra offers robust support for clusters spanning multiple data centers, with asynchronous master-less replication allowing low latency operations for all clients.

Cassandra relies on the Java platform, and as those of you who have tried to configure Java app monitoring most likely know, the experience can be painful. There are a handful of plugins on the Nagios Exchange that attempt to simplify the configuration. As these plugins rely on the Apache Cassandra utility “nodetool”, you either need to install Cassandra on the Nagios server (which is not suggested) or use an agent (like NRPE) to run the plugin script directly from the Cassandra server (which should have the nodetool utility).

The Cluster Node Check is designed to verify whether the number of live nodes is less than a specified number, and if so trigger a warning or critical alert within Nagios.
