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 is stable and it's easy to use the monitoring software, which is why we chose this product."
"I can monitor a software made in-house to software of bigger companies."
"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"The solution is pretty stable."
"The dashboard allows you to see what's going on in the overall system."
"The most valuable feature is the monitoring of processes."
"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability. We have multiple servers to monitor databases, availability of servers, and ping."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"The initial setup was straightforward. We didn't find it to be too complex."
"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."
"It can monitor, get the data, and then report on the data."
"It supports proactive management, enhances security, and improves operational efficiency."
"The solution's most valuable aspect is its ability to get information about all of the security measurements in my environment."
"The features I have found most valuable are log searching and log analytics, both of which are quick features."
"The most beneficial aspect of Splunk APM is the ATM, which is the map displaying the inbound and outbound relationships of the microservices, as well as the traffic between these dependencies. This feature provides us with valuable insights and helps us understand the interactions between different microservices."
"Once configured correctly, the analysis reporting the Splunk APM provides is better than that of the other APM tools."
 

Cons

"The tool's AI model needs to be fixed."
"They need more documentation for the plugins."
"Open-source software is usually not user-friendly."
"The product does not have SAP monitoring."
"Nagios XI can improve its GUI for users with a new look."
"Improve the documentation, examples, and best practices, therefore users can understand how to do things."
"Nagios XI can improve network and hardware monitoring, these parameters should be simplified to allow usage for monitoring. Additionally, if there was automatic reporting it would be helpful."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"The UI enhancements could be a way to improve the solution in the future."
"Once you see the issues related to the scalability part, you need to understand that it is a warning triangle. After seeing the warning triangle, you need to realize that you cannot trust any of the numbers you see in the chart because it is not a complete, full data set."
"There is a lot of room for improvement with the automation."
"The price has room for improvement."
"They can improve the flow system and the keyword language. It has predefined keywords, but they can be improved."
"The clustering part of indexes can be more refined."
"The cost needs to be re-examined. It's extremely expensive to run. It's also expensive to expand. That's the number one complaint all of my customers have when it comes to Splunk. It's way too expensive compared to other solutions."
"Splunk could be better integrated with configuration manager solutions so we can automatically resolve issues without human interference."
