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.

Messaging design has become visual and reliable and now supports fast microservice communication

The unique functions I appreciate about PubSub+ Platform are that it allows me to design my solution in a graphical manner, which is not available in many other products, and the design can also be pushed to the actual infrastructure layer, making it quite advantageous. Mesh technology is useful in scenarios where different geographies have to be connected, although such situations are not commonly found. It is beneficial but not a super-used feature of PubSub+ Platform. The event replay function is quite mature in PubSub+ Platform, allowing me to replay messages that are days in the past, which is a good feature. The main benefits PubSub+ Platform provides for the end-user include building a robust and scalable system with very low network latency, which improves the customer experience, whether using mobile phones or applications. This type of messaging framework is extremely important, and Solace is a very good product in that space. Nowadays, most applications are built using microservices technology, with small microservices interchanging messages via PubSub+ Platform. Without it, realizing a scalable system would not be possible; for example, one cannot have Netflix or similar services that require quick data transit and a good user experience, ensuring that data cannot be lost in transit. The analytics part of PubSub+ Platform is quite useful as it can connect with many analytical software tools, mainly for analysis of system logs, such as Splunk, DataDog, or Prometheus. It has the flexibility to connect with any of these and supports OpenTelemetry, which is not available in many other products, making traceability very easy. I can see how a message travels from a source system to the target system, end-to-end, along with what happens to that message along the path, making the analytics quite good.

Quotes from Members

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

Pros

"It is easy to integrate with other models such as Oracle, other systems, external systems, and to reach events."

"This product allows us to make use of open-source products, including running Java code."

"The operational views and third party connections to fetch the data and to help engage on more activities are the most valuable aspects of the solution."

"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."

"I can recommend Netcool/Impact because it's the perfect solution when it comes to invoking ISPF APA and using ISPF integration throughout the rest of your other products."

"The solution is great at being able to fetch almost any kind of file."

"The stability has been very good for IBM Tivoli NetCool Impact, rated around eight or nine."

"The topic hierarchy is pretty flexible. Once you have the subject defined just about anybody who knows Java can come onboard. The APIs are all there."

"I rate the PubSub+ Platform a 9 out of 10."

"The valuable feature of PubSub+ Event Broker is the speed of processing, publishing, and consumption."

"Capital markets couldn't operate today if Solace were down."

"When it comes to granularity, you can literally do anything regarding how the filtering works."

"Because we use it as a message broker, it makes information flow very seamless."

"Some valuable features include reconnecting topics, placing queues, and direct connections to MongoDB. The platform provides a dashboard to monitor the status of messages, such as how many have been processed or delivered, which is helpful for tracking performance."

"We have seen at least a 50 percent increase in productivity (compared to using Kafka) when using Solace for sharing changes in real-time, onboarding new subscribers, and modifying data sets."

More PubSub+ Platform pros

Cons

"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."

"Stability-wise, this product needs to be improved."

"For improvement, I'd say the dashboard and the overall GUI could use some work."

"IBM is not investing in the development of the on-premise version of this solution."

"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."

"The stability of this solution is somewhat less than other similar products that I have used."

"The solution is somewhat complicated. It's not exactly straightforward."

"We have requested to be able to get into the payload to do dynamic topic hierarchy building."

"The product should allow third-party agents to be installed. Currently, it is quite proprietary."

"Additional in-line information about certain things on PubSub+ Platform could be more beneficial for new users who are just starting to use this technology."

"For small-sized enterprises, it may be a higher cost, or they may be looking for other options."

"The section on observability pertains to understanding the functioning of an event crash. Instead of focusing on how the crash occurs, attention is given to the observable aspects, such as a memory pipeline where one person pushes messages and another reads them. However, this pipeline often encounters issues, such as the reader being unavailable, causing the system to become stuck and preventing the messages from moving forward. This can lead to the pipeline being permanently stalled."

"The ease of management could be approved. The GUI is very good, but to configure and manage these devices programmatically in the software version is not easy. For example, if I would like to spin up a new software broker, then I could in theory use the API, but it would require a considerable amount of development effort to do so. There should be a tool, or something that Solace supports, that we could use for this, e.g., a platform like Terraform where we could use infrastructure as code to configure our source appliances."

"For improvements, I would suggest increasing the max payload size to a limit of 100MB or more. The current max payload size is limited to 5MB."

"I heard that it is quite expensive compared to Kafka."

Pricing and Cost Advice

"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."

"It could be cheaper. Its licensing is on a yearly basis."

"I would rate the product's pricing a ten out of ten."

"There are different tiers where you can choose what would work for you. As a customer, you need to know roughly how many messages a month you will use."

"Having a free version is critical for our technology operations use case. This is primarily because our technology operations team is a cost center in our company. They are not profit drivers and having a free version for installation will probably meet our needs. Even for production, it'll support up to a 100,000 messages per second. I don't think in technology operations that we have that many events and alerts from our detection tools. Even if I have 20 or 30 event detection products out there, they're only going to publish the things which are critical or warnings. I don't think we'll ever reach a 100,000 messages per second."

"We have been really happy with the product licensing rates. It has been free for us, up to a 100,000 transactions per second, and all we have to do is pay for support. Making their product available and accessible to us has not been a problem at all."

"The price of PubSub+ Event Broker is reasonable for the capability it offers. However, when compared to others solutions on the market it is expensive."

"Having a free version of the solution was a big, important part of our decision to go with it. This was the big driver for us to evaluate Solace. We started using it as the free version. When we felt comfortable with the free version, that is when we bought the enterprise version."

"The pricing and licensing were very transparent and well-communicated by our account manager."
