Monitoring IBM i with IBM Systems Director 
IBM Systems Director is a robust tool for tackling a significant number of management tasks in the IT environment. In this article, Erwin Earley focuses on the capabilities that Systems Director provides for monitoring IBM i and IBM i resources and explores using Systems Director to monitor various system metrics, subsystems, message queues, and processes.
Using the Command Line for Discovery, Access, and Inventory 
Discovery, access, and inventory are three of the most basic -- as well as most often executed -- functions in IBM Systems Director. Before any management of an IT resource can take place from IBM Systems Director, the resource must first be discovered so it is known to Systems Director, and access must be requested/granted in order to be able to communicate with the resource. In addition, the inventory of the resource needs to be retrieved. There are times when the command-line interface will be the preferred method for executing these functions -- or it may be the only interface available. In this post, I will share both the web interface method as well the command line method for executing these three functions.
How to Integrate IBM i Message Queues with IBM Systems Director 
In previous articles and blog entries I have covered a number of features and capabilities related to the monitoring function of IBM Systems Director. In this blog entry I would like to share a method for integrating a feature of the IBM i operating system with the monitoring function of Systems Director to easily alert on critical events that occur in the operating system.
How to Use VNC with a Graphical Desktop from a PowerLinux System 
In a previous blog entry I showed how tools such as Xming and Cygwin/X could be used to work with X-windows applications from a PowerLinux system. In this article I would like to show how Virtual Network Computing (VNC) can be used to work with a complete graphical desktop from a PowerLinux system.
Tools to Check Network Port Availability 
As I have pointed out in previous entries in this blog, the availability of network ports is one of the most important pre-requisites of a successful implementation of IBM Systems Director and one of the most common issues that needs to be dealt with.  In this blog entry, I would like to share with you some tools and methods that can be used to check for port availability.
Handy Commands for Running IBM Systems Director on Linux 
A recent customer engagement provided me with the opportunity to install the Systems Director management server on an xSeries system running the Linux operating system.  During the process I discovered a couple of items that might be of interest.
How to Resolve Linux Package Dependencies 
The RedHat Package Manager (RPM) is a powerful software management tool used across a number of Linux distributions. One of the benefits of RPM is that package builders/maintainers can build tendency checks into their packages indicating if the package being installed is dependent on other files, libraries, or packages already being installed on the system. If RPM detects that dependency is not satisfied then the installation will not be attempted and an error message will be output.
