Executive SummaryUpdated on Feb 6, 2025

Splunk Observability Cloud and Nagios Core are in the competitive category of IT monitoring solutions. Splunk Observability Cloud holds an upper hand due to its capabilities in data integration, real-time analytics, and advanced visualization, while Nagios Core is preferred for cost-effectiveness and configurability.

Features: Splunk Observability Cloud is notable for its data integration, real-time analytics, and application performance monitoring. It provides extensive customization through dashboards and advanced data visualization. Users value its capability in proactive notification management. Nagios Core is valued for its robust monitoring capabilities and flexibility with plugins. It is highly configurable owing to its open-source nature, offers easily interpretable reports, and supports third-party modules integration.

Room for Improvement: For Splunk Observability Cloud, users recommend enhancements in integration capabilities and pricing structure, alongside improvements in technical support responsiveness and reducing configuration complexity.

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.

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.

"The company has many systems that the customer is paying to access. Splunk APM issued via AppDynamics helps find problems in the feed. It reduces the risk of supervising all the devices. I can supervise the flow and simulate the conditions of the repository across several dashboards to show what's happening at the moment."

"Detectors are a powerful feature."

"Splunk Infrastructure Monitoring provided our customers with visibility into their overall infrastructure."

"The feature I find most valuable, is the data integration."

More Splunk Observability Cloud pros

Cons

"Nagios Core does not have a graphic display."

"The mapping is a little hard."

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

"The alerting mechanism in Nagios Core could be improved."

"There is room for improvement in the graphics."

"The initial setup process could be easier."

"The dashboard should be improved."

"Cloud monitoring is an area for improvement because there aren't too many plugins available."

More Nagios Core cons

"We never had any issues when it comes to the type of use cases we are using it for. We did not need more advancement on it, but I know that, in general, everything can be updated. There are tiny little tweaks that can be made regardless of whether it looks better or has a different flow to it than it does right now, but it works pretty well for what we use it for."

"The solution should have more sensors regarding fiber intelligence for security measures."

"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."

"Splunk APM's performance could be improved - at the moment, it's very slow and takes forever to give me what I want."

"Splunk Infrastructure Monitoring's data analytics can be improved by including suggestions for various types of continuous monitoring."

"Splunk could be better integrated with configuration manager solutions so we can automatically resolve issues without human interference."

"There is not a lot of support for the tool's on-premises version, especially since everything is on the cloud."

"The deployment can be quite complex."

More Splunk Observability Cloud cons

Pricing and Cost Advice

"Splunk APM is a very cost-efficient solution."

"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."

"It appears to be expensive compared to competitors."

"I am not in that circle, but we are currently licensing based on our queries. That is working out for us. Previously, it was by volume of data, and now, we can store as much data as we want."

"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."
