Welcome to the Network and Service Assurance Blog, where you can read the perspectives from network and service assurance experts. This Blog provides insights into the network and service assurance solution, as well as technical details about specific IBM
To stay up-to-date with all the latest bugs, interim fixes, fix packs and new releases, monitor the IBM Tivoli Software Support RSS feeds: IBM Software Support - RSS Feeds For the Netcool/OMNIbus RSS feed, look for "Tivoli Netcool/OMNIbus" on this page. Note that there are feeds for Impact, Reporter, Webtop and others. The easiest way to monitor the feeds of your choice is to use an RSS feed reader client - like Mozilla Thunderbird. I find it works well!
When Netcool OMNIbus Web GUI users wish to monitor events for several different scenarios, it is not uncommon for the user to open multiple AELs over many tab pages in TIP (or even combining many AELs onto a single page). If each AEL was configured to use a different filter then this would allow the user to monitor different sets of events without frequent opening and closing of TIP tab pages. However, doing this can lead to poor performance on the client machine, primarily due to the amount of memory being consumed in total by all the Java... [More]
There is a new wiki for IBM Tivoli Netcool/OMNIbus, and it can be found here: https://www.ibm.com/developerworks/mydeveloperworks/wikis/home?lang=en#/wiki/Tivoli%20Netcool%20OMNIbus This
is the same content that you would have previously found on the Tivoli Event and Network Management wiki. As we continue
to migrate all Tivoli wikis to the new Lotus Connections technology that
we are leveraging for Service Management Connect, we made the decision
to have separate wikis for the individual event and network management products. This... [More]
Fix pack 2 for Netcool/OMNIbus 7.3.1 has just been released and is available for download from the IBM Support site: http://www-933.ibm.com/support/fixcentral/swg/selectFixes?parent=ibm/Tivoli&product=ibm/Tivoli/Tivoli+Netcool+OMNIbus&release=184.108.40.206&platform=All&function=all
Hello all, My name is David Morton and I'm a developer for OMNIbus core. I've decided to kick off my blogging career with a guide on how to use OMNIbus triggers to get an accurate event rate in your ObjectServers! I have talked to a few customers that use their event rate as a performance indicator for their ObjectServers. I plan on outlining an efficient way to measure this using only triggers and tables in an ObjectServer. I'll try my best to keep this guide version agnostic so that anyone should be able to use it. If you use other metrics... [More]

Before you install Tivoli Netcool/OMNIbus V7.3.1 server and desktop component, you could run the prerequisite scanner to check if the target system's hardware and software condition meet the minimal requirement. The prerequisite scanner is easy to download, install and run. The scan only takes several minutes and it could potentially save you a lot of time on troubleshooting installation problem. For more information on how to install and run this tool, please see this tech note. If you have any comment or suggestion on this tool, please... [More]
Hello again, I found another great topic to write up a blog post for. There are often times when you would like your ObjectServer to make decisions based on some sort of external piece of data that might be available on the host. This could be useful if you would like to track the performance usage of your ObjectServer to get a better feel for its utilisation. Here is a neat little way you can track external metrics like this using an ObjectServer and a small script. In this example I am going to track the %CPU, %MEM and total memory used... [More]
Welcome A fine afternoon to you, the Developer Works reader, I'm James Grafton a developer on
the Omnibus Web GUI team and I'm here today to blog to you about Java Heap Dumps!
Java heap huh? A Java heap dump is a snapshot of the entire memory structure of your Java program at a
specific point in time. Sounds useful, how do I get one? As long as you're using an IBM based JDK there is a rather handy guide here .
Essentially it's just a case of setting an environmental variable at launch, then, at
some later point, sending the... [More]
Sometimes there is an implied hierarchical relationship between the events that you monitor using Netcool OMNIbus Web GUI. Of course, the Active Event List displays events as a simple flat list. However, it is possible to create a type of "drilldown" behaviour between AELs, in order to help you navigate down through your event hierarchy. Doing this involves the use of a few key Web GUI concepts: Script tools Transient filters TIP events In this blog entry I will lead you through a simple example of how to set up event drilldown...

OMNIbus server components and probes started to use ICU for date/time formatting and parsing in V7.3.0. We have seen some date/time formatting and parsing related problem recently. There are some tips to help your migration. 1) Minor incompatibility to OMNIbus versions prior to V7.3.0. You might want to check this table when you are migrating from a version older than V7.3.0. Table 1. Compatibility for POSIX format in date and time conversion in V7.3.0 2) Timezone environment variable "NFT-1DFT" on AIX is not a valid timezone... [More]
The OMNIbus Sizing Guide has been updated and is now available for external use by customers and partners. It can be found under the planning section of the wiki here: https://www.ibm.com/developerworks/mydeveloperworks/wikis/home?lang=en#/wiki/Tivoli%20Netcool%20OMNIbus/page/OMNIbus%20Sizing%20Guide A downloadable pdf version will also be made available soon.
Using Netcool/Impact to perform the function of a OMNIbus gateway is not something you would normally do. But, we had contractual issues that prevented us from using the gateway. Since it was already installed, we decided to use Impact to emulate the gateway. The policies and descriptions are found on the developerWorks Tivoli Netcool Impact wiki:
Don't be intimidated by the size... [More]
