Event management strengthens with automation but needs better event flooding handling
Better handling of event flooding in IBM Tivoli NetCool Impact would be beneficial. If there are massive issues with power, for example, and we get millions of events, then it struggles to deal with that. Better root cause correlation and faster processing for IBM Tivoli NetCool Impact would be helpful. If there can be more end-to-end functionality, such as observability tools built in natively, that would be great. With correlation, IBM Tivoli NetCool Impact has many functions, but we've built them custom-built. Functions such as automated logging, automated dispatching, and automated notification of engineers could be native in the tool.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable feature is NetFlow."
"The Pipeline's Comprehensive Insights into data flows have helped improve operational efficiency and security."
"The tool's most valuable feature is the encryption feature. From a security perspective, the solution hasn't significantly strengthened our security posture. However, it has greatly improved performance by streamlining encryption processes and avoiding encryption at multiple layers. This has also simplified troubleshooting, as we can whitelist certain processes."
"The solution is straightforward to set up."
"It is a good product. It provides network visibility, which is important. Gigamon can bring some optimizations to my network. It is helpful for security inspection, and it makes my firewall work fast because my firewall doesn't have to do the inspection of the SSL connections, for example."
"It offers straightforward integration."
"It has high stability."
"The most valuable feature for improving network visibility with Gigamon is the packet filtering capability."
"This product allows us to make use of open-source products, including running Java code."
"The stability has been very good for IBM Tivoli NetCool Impact, rated around eight or nine."
"The most valuable feature that comes with Netcool/Impact is the ISPF APA support. It is inherent to Netcool/Impact, so I can use the ISPF of any other product, which I can invoke and consume through Impact, and do integrations, which is great. I run the Netcool desktop application so I can integrate with other applications in the ticketing system. It's a great ability being able to invoke ISPF and integrate."
"The solution is great at being able to fetch almost any kind of file."
"It is easy to integrate with other models such as Oracle, other systems, external systems, and to reach events."
 

Cons

"Its filtering feature needs improvement."
"The security should be improved."
"In terms of improvement, while the initial setup is not overly complicated, we did encounter a few issues."
"They should increase the solution's cluster capacity."
"Gigamon Deep Observability Pipeline needs to improve its performance. I face issues with performance because we use SPAN, and the SPAN traffic is not good."
"The graphical user interface could be improved."
"The Gigamon Deep Observability Pipeline should have a feature showing the traffic flow within its platform. Currently, customers have to use separate tools for monitoring, which is inconvenient. If it had its visibility feature, it would make monitoring easier and more complete without needing extra tools."
"It only inspects a specific kind of traffic. There should be different kinds of use cases."
"Better handling of event flooding in IBM Tivoli NetCool Impact would be beneficial. If there are massive issues with power, for example, and we get millions of events, then it struggles to deal with that."
"Stability-wise, this product needs to be improved."
"IBM is not investing in the development of the on-premise version of this solution."
"The solution is somewhat complicated. It's not exactly straightforward."
"For improvement, I'd say the dashboard and the overall GUI could use some work. Although, I don't think that there's much improvement that Netcool really needs to achieve in this area, because when we're talking GUI, Impact is able to integrate with any third-party system and it comes with ISPF APA. It's more beneficial than Netcool/OMNIbus in this respect, and it's quite easy to handle."
 

Pricing and Cost Advice

"The solution's price is reasonable."
"The solution is highly-priced."
"I would rate the solution as expensive, around an eight or nine out of ten. There are other competitive solutions available."
"The licensing is yearly, and although I'm happy with the pricing I do think it could be better."
"Licensing of IBM Tivoli NetCool Impact depends on the number of nodes on the element that you are monitoring."
