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.
The "IBM Monitoring Academy Seminars" are a series of LIVE video blogs presented by Mark Leftwich and Shaun Rodger. The series is designed to be slightly less formal and give you the latest monitoring information directly from the hand on experience of our subject matter experts. We work on the products daily, work on site with customers and are always up to speed with the latest information on the products. We are now passing this information on directly to you in a nice easy to digest format.... [More]
Hi All - In this specific example we will use the Oracle 1.7 JRE, a browser client and an Apache reverse proxy (which provides a https based URL which is redirected via the junction to the TEP console at a http URL). As there are an array of JREs, reverse proxy and browser combinations it is not possible for IBM to verify and officially support them all, but hopefully these steps will help you along the path of making the successful connection from your browser to the TEP console! For reference, this configuration has only been tested... [More]

In this new blog I'm going to cover the installation/configuration the TEPS on HACMP cluster and “overall” what to check to be sure it was configured correctly. Obviously if our TEPS starts and failover without any problem then it is a great indication that it was well :-)))) but it may be interesting to know what files are modified in case, for example, we have to change the hostname or find files making reference to the physical name making us to think about If TEPS was configured well or not . When... [More]
This set of blogs will be short entries about issues seen recently and have been solved. Just generally anything that might be useful. Each blog will be on one subject. NFS mount for deploy depot not seen by TEMS applications This was one of those issues where all the usual areas had been checked, the NFS was mounted correctly and permissions for the users was correct, however ITM would not see the depot. In the logs for the deply command there was an error: "Unable to load deliver_message proc, status = 5" It was... [More]

Using IBM Performance Management 8.1.1 you can now easily monitor the IBM Java application stack from the browser, to the web server and application server, all the way through to the database. If you want to monitor IBM HTTP Server, IBM WebSphere Application Server, and IBM DB2 or Oracle database, this new functionality is for you. Read more about how to monitor the components in the IBM Java application stack and the resulting enhanced topologies in the Scenarios topic in the IBM Knowledge Center.
Hello all, It has occurred to me that perhaps some of you out there aren't entirely familiar with a product called Tivoli Common Reporting, or perhaps you're a little confused by all the different versions and you're wondering what each one offers you in terms of functionality. Or maybe you're having some problems with your reports and you're thinking about logging a PMR with IBM Support. If any of the above applies, then this video is for you. If you have any questions not answered in... [More]
Introduction : Managing the short term history file, one need to be very careful how to configure the system so that the short term history is not compromised. Care is required to set the correct disk space and to avoid performance issues caused by data loss. ... [More]

Changes to Managed System lists with tacmd There has been a change brought in at 6.3 FP02 that allows a MSL to exist with no members subscribed to it. This allows MSL's to be created before you know the managed systems you want to allocate to it. It also allows the last member of a MSL to be removed... [More]
Thresholds are used to compare the sampled value of an attribute with the value set in the threshold. If the sampled value satisfies the comparison, an event is opened arriving to “Event Status”. The event closes automatically when the threshold comparison is no longer true. it is what we called “situations” and they work in a similar way to the “private situations” in previous versions . The thresholds running in an agent are included in a .xml file located in... [More]
The normal behavior we are used to see for the historical collections is to have like minimum a warehouse proxy agent installed in our environment and configure via TEP/“history configuration....” the attribute groups to be collected and the agents which have to collect them. Now we have other option, it is to use the “private history”, configuring the attributes to be collected in the agent by a .xml file located in the agent , so the agent starts collecting historical without using TEMS/WPA at all , it works in...

Announcing IBM Monitoring v8.1 - the next generation of Application-Aware infrastructure monitoring solution that simplifies the life for IT Ops. With a single end to end view of metrics and logs/errors collected across the application stack, IT operators can detect problems and troubleshoot in the context of the application always. They no longer need to struggle to understand which component belongs to which application or which application's performance will be impacted due to a failed infrastructure component. It is able to monitor any... [More]

Parameters added to the jnlp file after 63. FP03 Customer previous to 6.3 Fp03 had the following lines in the .../cw/tep.jnlp file on the TEPS server. <property name="cnp.navigator.branch.pagesize" value="-1"/> <property name="cnp.navigator.branch.threshold" value="-1"/> This was to stop the popup...
