A suitable choice for unified and efficient infrastructure monitoring across diverse environments providing user-friendly GUI, cost-effectiveness, and versatility
We use it for this specific client, they've deployed multiple instances of it across various locations to facilitate monitoring. To effectively monitor their infrastructure, it seems necessary to implement additional monitoring solutions for all three types of devices they have Nagios Fusion…

Alerting improves incident response across teams and enables faster awareness before customer impact
Splunk Observability Cloud could be improved in terms of integrations with more technical add-ons, such as Zoom. Although they have one with Zoom, it's not available in the cloud, so having that feature would be beneficial. Essentially, Splunk should continue expanding to create easier ways to ingest logs from different products. The out-of-the-box customizable dashboards in Splunk Observability Cloud are very effective in showcasing IT performance to business leaders. However, there are aspects that could be improved, such as linking dashboards to one another. While IT leaders may not drill down, it's crucial to create levels of dashboards for technical users to find root causes, making it effective for stakeholders.

"It is easier for client installation, and the configurations are doable even for a newcomer in the field."
"It's very easy to manage and monitor it."

"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."
"It's very easy to manage and monitor it."
"The solution's service map feature allows us to have a holistic overview and to see quickly where the issues are."
"The best feature of this product is the latency and processing of all the telemetry that is being received, which gives full visibility at the right time."
"Detectors are a powerful feature."
"Splunk Real User Monitoring (RUM) has one great advantage in that if they have SAP users, they can monitor their SAP applications."
"The features of Splunk Observability Cloud that I prefer the most are its all-encompassing licensing model, which is comparatively better than others in the market."
"The solution monitors attacks or unauthorized access to the information we want to protect."
"My experience with this solution in analyzing machine data is really good."
"From an ROI perspective, Splunk Observability Cloud offers much higher value because, as I mentioned earlier, our MTTR has reduced by more than 50%, which decreases the overall downtime for our application."
 

Cons

"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."
"There are some bugs, although not that many. There are some situations where the solution is not stable but the number of problems is not very high."
"There are some bugs, although not that many. There are some situations where the solution is not stable but the number of problems is not very high."
"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."
"The only strain point we've encountered with Splunk Observability Cloud is that the search times can be lengthy for some things."
"To improve Splunk Observability Cloud, we need more applications to be included in the observability so that more applications can have agents to monitor them and bring that information to the cloud."
"I would like to see an improvement and some innovation in the customer interface, which puts something in your design."
"Splunk's functionality could be improved by adding database connectors for other platforms like AWS and Azure."
"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."
"Unfortunately, with our current setup, we just have to implement Log Observer in a couple of instances so that we can have that integration with Splunk Observability Cloud."
"In Splunk Observability Cloud, I notice room for improvement in synthetic monitoring. It does not provide output based on server names."
"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."
 

Pricing and Cost Advice

"The pricing is quite reasonable, especially when compared to the broader market."
"It is expensive."
"Splunk APM is expensive."
"The product is a bit expensive considering the competition but the company may negotiate the price."
"The solution's pricing is costly."
"Splunk has been fairly expensive, but it has been predictable."

"Splunk APM is a very cost-efficient solution."
"Splunk offers a 14-day free trial and after that, we have to pay but the cost is reasonable."
