Improves infrastructure planning by helping us analyze network traffic

We use SevOne to collect and report on network flows SevOne improves infrastructure planning by helping us analyze network traffic. We can look at bandwidth for specific endpoints on the customer's network and analyze traffic to identify issues. For example, maybe some connectors are unavailable.…

Valuable reporting and alert system with room for PDF export improvements

The NetEase reporting structure needs improvement, especially the availability report, which is weak. It should be generated automatically with minimal human intervention and should be exportable as a PDF. Besides that, an integrated PDF export feature for reports is necessary. Also, the alert mechanism and graphing mechanism need to be integrated properly into Nagios Core. Currently, integrating these requires advanced Linux knowledge. Integration of more visualization tools like Grafana and Prometheus for better graphing and visualization is also recommended.

Quotes from Members

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

Pros

"SevOne has rich API capabilities, giving us the flexibility to control what we collect and customize the collection, creation, and manipulation of now metrics as necessary."

"The most valuable feature as of late has been the API integration with ServiceNow."

"The feature that I have found most valuable is the scale-up and scale-down. The scale-up is an operation where the CPU boosts-up and then the memory will boost-up. That works awesomely."

"The automation feature is good because if your CMDB is OK and it is already in sync, then the automation part is good to go."

"We find that the reporting is particularly valuable in terms of not only communicating with our peer teams but also with the executives."

"The comprehensiveness of this solution's collection of network performance and flow data is one of the basics in the field for what it does. It meets all of our needs. So for all those areas, for the most straightforward collection capabilities, right up to NetFlow and even telemetry, it meets all those demands. Not only just basic or fundamental SNMP collection capability, but the product also supports what we need for the future with telemetry streaming. So it's very comprehensive."

"Flexible architecture: You can extend the system and its capacity by attaching another cluster pair."

"With this tool it is interesting to show the info to the client and explain where the traffic is."

More IBM SevOne Network Performance Management (NPM) pros

"We mostly use Nagios Core to integrate with Python and Bash Script."

"I like the way the solution sends alerts and how it keeps on escalating them."

"The notifications are definitely one of the most valuable features of Nagios Core. We know what to look for and what to expect when things are down."

"Nagios Core is very configurable. Whatever you want, you can do it."

"The good thing about Nagios Core is it covers everything."

"Nagios Core is stable."

"The solution's most valuable feature is that it offers proper alerting capabilities."

"Provides timely notifications."

More Nagios Core pros

Cons

"High-frequency polling is data-intensive because you're pulling more. If SevOne could figure out a way to manage the impact of high-frequency polling on the system, that would be very popular."

"We need to be thinking about streaming telemetry protocols. They already have the port for enhanced visualization, which they already have through Data Insight."

"The customizations are very hard. The person doing it has to be very good at analytics and has to be very good in all languages"

"Software upgrades can be tricky is not easy."

"There is no service mode setup in this monitoring tool if you want to snooze alerts for any specific amount of time, to account for any activity change or major incident."

"I would like to see live maps as an added feature. Also, build modules on AI and EML to provide better data insights that would proactively tell us what we should be looking after."

"I'm not really sure if this was the software's fault or a server issue, but a couple of years back the disks were failing on our SevOne physical server every month and the server would go down. The secondary server took over from the primary until the disk issue was resolved. That was annoying."

"User-friendly, multi-tenancy."

More IBM SevOne Network Performance Management (NPM) cons

"It would be nice if the company offered a sales or contract manager that was dedicated to our company so that we would have some sort of link to Nagios, and if we had issues or questions, we'd be able to contact them directly."

"Nagios Core does not have a graphic display."

"We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier."

"The tool needs to improve the integrations."

"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."

"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."

"The mapping is a little hard."

"The NetEase reporting structure needs improvement, especially the availability report, which is weak."

More Nagios Core cons

Pricing and Cost Advice

"Choose a SevOne partner who can provide SevOne as a service and can deliver professional services and maintenance."

"Have a bank of licenses, because it is about the number of objects (RAM, ports, CPU, etc.)."

"There are different options available for licensing, with the per-device option being more expensive but more flexible."

"There are cheaper solutions available."

"The tool is not expensive. We were able to negotiate with SevOne on pricing."

"Although I don't have exact details in terms of cost, my experience has been that SevOne is willing to make a deal with the customer."

"A blocking point is the high upfront cost because it is challenging to get it accepted and the purchase approved."

"Many tools price things based on the number of KPIs that you're collecting around a device. In many cases, there could be hundreds of metrics that you need to collect. SevOne provides device-level pricing. That gives us the flexibility to turn on, and expand on, the metrics that we're collecting around those devices, without taking a financial hit."

More IBM SevOne Network Performance Management (NPM) pricing and cost advice

"Nagios Core is an open source solution, and there are no licensing fees."

"The enterprise version has technical support. The version we are using is free."

"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."

"We are using the free version of Nagios Core."

"We are using the open-source, unpaid version."

"Nagios Core is a cheap solution."

"The product is cheaply priced."

"Nagios Core is free to use."
