Welcome to the Application Performance Management Blog, where you can read the perspectives from APM experts. This Blog provides insights into the Application Performance Management solution, as well as technical details about specific IBM products.
Sometimes I am confused whether to use the word "affect" or "effect." I usually get it right, but I do have to think about it first. Of course, affect is the verb and effect is the noun. The confusion can come in because there are rare instances when affect can be used as noun and effect as a verb. Use your favorite search engine to look up "affect vs effect" and read all about it. Within the System p world, there can also be confusion over the metrics physb and physc. Basically, here are the definitions... [More]
You have just bought your
first smart phone. You then have to decide on how to use 'less data'
using your data plan(unless you are on an unlimited plan). You
google 'how to use less data' and see there are thousands of posts on
how to do this. In terms of Tivoli ITM warehousing, the same concept
applies, how to keep the short term history(STH) files at a
reasonable size. This requires for large data intensive agents to
think about the configuration of the historical collection interval,
warehousing upload interval, and retention... [More]

Big Data as described in Wikipedia is the future but right now for Tivoli Data Warehousing(TDW) the task is to understand the amount of data being collected and warehoused by the Tivoli agents in your ITM infrastructure. This analysis can be simplified using the Tivoli Warehouse Projection Spreadsheet that is located here: Warehouse Projection Spreadsheet and has been uploaded to this blog entry . The ITM 6.2.3 Installation and Setup Guide contains information on estimating the disk space requirements for the Tivoli Data Warehouse. To follow... [More]
One of the critical challenges with IBM Tivoli Monitoring is managing Operating System agents, specifically, executing some operations (OS commands, scripts, etc.) remotely on your agents. IBM Tivoli Monitoring 6.2.2 Fix Pack 2 introduced a new set of command lines: tacmd getFile allows you to retrieve a file from an agent. tacmd putFile allows you to push a file to an agent. tacmd executeCommand allows you to run a script or command and to retrieve the stdout, stderr and stdin. The benefit of using the above commands is that you can... [More]
Imagine you are busy perusing your e-mail when a critical alert occurs on a system within your environment. Wouldn't it be nice if you could receive a message containing a link that would open the Tivoli Enterprise Portal and take you right to the relevant area so you could investigate? This post shows how use Tivoli Monitoring facilities to automatically send a message to do just that. I assume you are familiar with the Tivoli Enterprise Portal Situation and Policy editors and will not go into great detail about them. Here are the steps: ... [More]

After a colder than normal winter in North Carolina, Spring is finally here. While today's high of 45F is nearly 20 degrees below normal, this past Saturday gave a taste of Spring with a beautiful, sunny 74F day. After hibernating most of the Winter, these turtles came out in force at a local pond to see what is new under the sun.
So what else is new this Spring? It is the new ITM HMC Base agent v22.214.171.124, and it might replace your CEC Base agent. If you have used the CEC Base agent, you have probably know the requirement that the AIX... [More]
The latest release of the VMware VI agent is now available as part of a number of products, including IBM Tivoli Monitoring for Virtual Servers 6.2.3, IBM Tivoli Composite Application Manager for Applications 6.2.4 and IBM Tivoli Composite Application Manager for Microsoft Applications 6.2.3. The new agent provides the following enhancements: Network monitoring. You can now see the configuration of key virtualized network components and traffic usage by virtual machines and hosts. vCenter alarm monitoring. You can now see the vCenter alarms... [More]
In my previous blog entry , I detailed how to configure historical collection so that the least amount of data is saved and the export of that data is the quickest. All for keeping the size of the short term history file below 1GB. However, when saving historical data at the TEMA the agent can become isolated from the Warehouse Proxy agent because of network issues. Or the database itself may be down not allowing exports. When this happens, the STH files start growing and can exceed the 1GB limit over time. At the TEMS, this can also... [More]
This scenario describes how you can use the WebSphere MQ Monitoring agent to monitor multiple alias queues that are used by different applications. Background: The XYZ company uses WebSphere MQ network to enable communication between multiple applications. In their WebSphere MQ environment, there are 150 alias queues pointing at one local queue. They want to know the impact that each alias queue has on the local queue with the WebSphere MQ Monitoring agent. Especially when the local queue is overloaded, they expect to know which of the alias... [More]
In my previous blog entry we discovered that each short term history(STH) file must be kept
under 1GB in size for performance reasons at the TEMA (Tivoli
Enterprise Monitoring Agent) or TEMS (Tivoli Enterprise Monitoring
Server). As with any smartphone data plan it is always good to have
ways to try and not exceed this limit. And for STH files the same
applies. Here are ways to achieve this: Use
the largest collection interval possible. This reduces the number
of rows saved in the STH file. Filter
any unneeded data from the... [More]
You might have heard the old adage, an ounce of prevention is worth a pound of cure. Metrically, perhaps it is a gram of prevention and a kilogram of cure. In our home, vitamin C and zinc are our home's attempt to ward off colds, but I wish our ounce of prevention could come in the form of chocolate! Whatever works, the low-cost, proactive steps that prevent bigger problems later on are always worth it! And of course the same is true with information technology. Part of the reason you are running Tivoli monitoring software is not only for... [More]
IBM Tivoli Netcool Configuration Manager (ITNCM) helps data center and networking staff to discover, visualize, detect, configure and activate the network. ITNCM consists of two servers: an application server and a database server. The application server is made up of a Web Start graphical user interface (GUI) and web-based HTML interface. The Web Start GUI provides access to the queue manager, resource browser and system and archive manager. The web-based HTML interface provides access to the account management interface, process and policy;... [More]
ITCAM for Application Diagnostics (AD) and ITCAM for WebSphere products have a Data Collector that runs as part of Application Server process being monitored. To provide diagnostic data the Data Collector (DC) acts like a server and is queried by the Managing Server (MS) unlike many agents where data is propagated only one way from the agent to upstream components. One of the popular deployment models is to have the Managing Server inside the firewall and Data Collectors outside the firewall. This creates a problem of opening many ports... [More]
