Effective alerting enhances network monitoring experience with an easy setup
We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.

Collaborates performance metrics with log data to pinpoint the exact cause of issues and offers error detection
Splunk APM is a robust tool with many capabilities. There are always areas for potential improvement to enhance its functionality and user experience. For Splunk APM, there could be simplified navigation, like streamlining the user interface to make navigation more intuitive for our users, especially those new to APM, which can enhance usability. We can provide more customization options for dashboards and visualizations to help users tailor the platform to their specific needs. There could be more integration capabilities with a wider range of third-party tools and platforms would also be beneficial. By focusing on these areas, Splunk APM can enhance its value proposition, improve user satisfaction, and better meet the evolving needs of organizations monitoring their application performance.

Quotes from Members

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

Pros

"Nagios XI is a simple monitoring tool with performance management."
"The most useful aspect of this solution is the ability to customize it for the client agent."
"The Script Module in Nagios is really easy to use and is really cost efficient."
"The solution has a lot of plugins and scripts integrated with it."
"The most valuable feature is the monitoring of processes."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"The most valuable features of Nagios XI are you can customize it based on your use case and requirements. It is flexible and easy to integrate with our systems. You can customize the solution by adding additional features using code."
"Nagios XI is stable."
"The feature I find most valuable, is the data integration."
"It is very easy to monitor multiple cloud environments. It's like a single pane of glass for us. We can use it to monitor our on-prem and both of our cloud environments as opposed to having different tools for each environment. It makes it all come together in one tool."
"The solution is stable and reliable."
"It supports proactive management, enhances security, and improves operational efficiency."
"The volume it handles is very good, including the number of metrics, the volume number of traces, and more."
"Splunk APM helps us to find errors immediately and resolve them."
"The vibrant dashboards are valuable."
"The most valuable thing that we have seen within our group is the ability to ingest all this raw data and have it organized in a certain way so that different groups can get effective alerting from this massive amount of raw data that is out there."
 

Cons

"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"From an alerting point of view, some graphics and metrics don't work properly with Nagios XI as they do with Checkmk."
"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"I would like to see support for notification via SMS."
"They need more documentation for the plugins."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it."
"The reporting part should be made simpler. While we can obtain all the reports we need, we always have to create work-arounds to get them."
"There are always areas for potential improvement to enhance its functionality and user experience."
"We still use Splunk Enterprise licensing. A lot of the newer features go into Splunk Cloud before Enterprise. We're not looking to switch our licensing over, so we're falling behind on the newer features."
"They do not have all the features that I expect right now."
"I've been using the Splunk query language, and it can be a bit time-consuming to set up the queries I need."
"There are some predefined metrics.......we may want to create customized metrics."
"There is a lot of room for improvement with the automation."
"A lot of customers had a hard time effectively searching within the data in Splunk. There is a learning curve from searches to indexes and using all the macros that we have created. It is a little difficult for somebody who has not used it quite a bit and does not have a lot of practice with it, but the AI features that we have been hearing about through Splunk will make it a lot easier for us to use human language to search this data. That is big. That is pretty powerful, and that will help a lot with our customers."
"The implementation can be more user-friendly."
 

Pricing and Cost Advice

"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"Nagios XI is open source."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."
"For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value."
"As it is not an agentless tool, I think it is expensive."
"Nagios XI is an expensive solution."
"For our country in North Africa, it's expensive and we could purchase another solution for that price. But it's a reasonable price if we're speaking in international terms."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Splunk has been fairly expensive, but it has been predictable."
"The solution's pricing is competitive. I rate the solution's pricing a seven out of ten. The price of the solution could be cheaper."
"This is an expensive solution."
"The pricing is reasonable."
"I would rate the price of Splunk Infrastructure Monitoring as an eight out of ten, with ten being the most expensive."

"The pricing is based on several factors, including the scale of deployment."
"The solution's pricing is costly."
