Think a situation should be firing and it isn't? You can always do a quick and dirty check to see what is happening at the HUB by using the kdstsns tool to query the TEMS database. This is an internal tool and it is an easy way to "dump" information from the TEMS tables. It is located under the following directories: Windows - $CANDLEHOME\cms UNIX - $CANDLEHOME/Mplatform>/ms/bin You must set SQLLIB to the location where the SQL you want to run resides. example: WINDOWS: set SQLLIB=c:\IBM\ITM\cms\sqllib UNIX: export...

The Tivoli Data Warehouse utilizes a very simple and flat database schema. This simple schema means that certain queries may not perform well, depending on how they are written (complexity, joins, order by, columns used in the WHERE clause, etc...). This article describes some of the best practices when setting up your Tivoli Data Warehouse. Data Collection only collect the data that you need - collecting unneeded data will take resources in the database and will require extra maintenance in the form of pruning, etc... It will also increase... [More]
We often hear requests from customers who want to measure a percentile , such as the 95th percentile, of transaction response times. That is, given a set of response times, what is the response time that 95% of transactions were faster than and 5% slower than. For a short time period, say 5 minutes, the 95th percentile of transaction response times can be efficiently calculated. Assuming the transaction rate isn't too high, it is even easy to calculate it for an hour or a day. But for many of our customers, the transaction rate will be... [More]
The ITCAM for Microsoft Applications team has published 7 new video demonstrations to the Tivoli Media Gallery.

The new Agent Builder version 188.8.131.52 is now available for download. The new release introduces really important features hereafter described: The Socket data source allows data to be easily provided to the agent from an external application on the same system. The Java™ application programming interface (API) data source enables data to be collected in a long-running process that is separate from the agent process, allowing greater flexibility in the type of data that can be collected. The number of agent versions available has increased... [More]
ITCAM for SOA v7.1.1 allows you to examine the metrics and relationships by requester identity for a specific service port and operation pair. http://publib.boulder.ibm.com/infocenter/tivihelp/v3r1/topic/com.ibm.itcamsoa.doc/kd4ugmst70.htm#ws_reqidforoper Effectively, this enables you to track whom is using what resources - a very important feature. However, the product has a 64K char limitation on the Req ID field. This is currently listed as a feature enhancement request (MR1104104015) to make it 256K. To make things worse, the DN... [More]

A new video has been published to the Tivoli Media Gallery about a usage scenario for ITCAM for Application Diagnostics. Identifying and analyzing performance problems in JEE environments is one of the key features of this product. This video demonstrates a typical error resolution flow from sensing a potential problem to the analysis of the root cause of the issue based on an example of a memory leak within the enterprise application. A set of videos about ITCAM for Application Diagnostics videos can be found here .
Five new videos have been posted to the ITCAM for Transactions Media Gallery . These videos showcase some of the new features in ITCAM for Transactions 7.3: Agentless transaction tracking with the Web Response Time agent TCP Monitoring workspaces Transaction topology workspaces that combines data derived from agentless transaction tracking and more traditional agent-based tracking techniques Internet Service Monitoring Configuration command line tool

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]
ITCAM for Transactions 7.3 is now available to download. It includes a significant new feature called "agentless tracking", which is a very fast and simple way to get an overall picture of your environment's transaction performance. It captures network traffic and reports the interactions between servers and applications. It integrates seamlessly into the existing user interface, combining the breadth of agentless tracking with the depth of agent-based tracking . Agentless tracking is built on top of the proven Web Response Time... [More]
