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.

Pros

"We love Nagios XI due to the fact that JPS Web is very useful."
"The dashboard allows you to see what's going on in the overall system."
"The most valuable feature is the monitoring of processes."
"Nagios is stable and it's easy to use the monitoring software, which is why we chose this product."
"The solution's most valuable feature is its simplicity."
"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."
"The technical support is good."
"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."
"The most valuable features are troubleshooting and optimizing application performance."
"The volume it handles is very good, including the number of metrics, the volume number of traces, and more."
"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."
"The alerts are the most valuable feature."
"The tool is efficient in collecting, monitoring and evaluating logs."
"It's a very easy-to-use solution."
"Splunk Infrastructure Monitoring reduces our mean time to resolve. We are more proactive than reactive."
"The Add data feature lets you gather any type of log and easily analyze it."
 

Cons

"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"The product's stability could be even better."
"The interface could be more user-friendly."
"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."
"Improve the documentation, examples, and best practices, therefore users can understand how to do things."
"The scalability of Nagios XI is scalable. However, it is not easy to do."
"We often need to develop custom plugins to get Nagios to work the way we want it to work because the features we need are not always available in Nagios."
"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"There is not a lot of support for the tool's on-premises version, especially since everything is on the cloud."
"The cardinality is pretty low."
"The licensing model is expensive. We need to monitor the amount of data ingested because the cost is based on the data collected."
"The product collects a lot of data but it does not assure that it collects all of it."
"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."
"There is a lot of room for improvement with the automation."
"Primarily, the logs in Splunk APM can be challenging to navigate and comprehend, making it difficult to understand the details within each log. Compared to other tools like LogDNA, which are more intuitive in this aspect, the logs in Splunk APM can require more effort to understand."
"The security could be better."
 

Pricing and Cost Advice

"The licensing fees for this solution are approximately $3,000 USD per year."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"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."
"Licensing costs are reasonable."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"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."
"Nagios XI is an expensive solution."
"The pricing is high with separate licensing for the product and support."
"The pricing is reasonable."
"It is expensive."
"This is an expensive solution."
"It appears to be expensive compared to competitors."
"The product is a bit expensive considering the competition but the company may negotiate the price."
"Licensing cost is the biggest argument I get from those divesting from Splunk. There are those within our organization who say we are going to go to other tools since Splunk is too expensive."
"The pricing is based on several factors, including the scale of deployment."
"The price of Splunk APM is less than some of its competitors."
