Nagios Core and Splunk ITSI compete in the IT infrastructure and advanced analytics monitoring space. Splunk ITSI seems to have the upper hand due to its advanced features and comprehensive monitoring capabilities.
Features: Nagios Core offers configurability, broad monitoring capabilities across diverse environments, and simplicity. Splunk ITSI provides predictive analytics, machine learning insights, and a comprehensive service-view dashboard.
Room for Improvement: Nagios Core could modernize its notification system, integrate advanced analytics, and update core functionalities. Splunk ITSI could enhance integration with third-party tools, improve its learning curve, and streamline usability.
Ease of Deployment and Customer Service: Nagios Core has straightforward deployment for open-source familiar users and strong community support, though it requires manual configuration. Splunk ITSI has a complex deployment requiring professional services but offers robust customer support and documentation.
Pricing and ROI: Nagios Core is cost-effective with high ROI due to low setup costs. Splunk ITSI has a higher initial investment but delivers strong ROI via advanced features and analytics capabilities.
We estimate a 30 to 35 percent saving on resource costs and around 25 to 30 percent savings on inventory expenses, all credited to utilizing Splunk ITSI (IT Service Intelligence) effectively.
Risks can mean that if one failure happens, it can result in risks in hundreds of thousands of USD.
It has saved me a lot of money and a lot of time.
The technical support is excellent, and I would rate it at ten.
We typically have weekly calls with the technical staff, and whenever we encounter issues, they usually reply with solutions within one or two days.
I would rate Splunk ITSI (IT Service Intelligence) support at nine or 9.5 because it is a highly effective and handy tool.
The solution is scalable.
Splunk is highly scalable, with the ability to expand efficiently.
When we create Glass Tables containing many searches, the Glass Tables sometimes fail due to memory constraints, and we receive error pages.
Splunk ITSI (IT Service Intelligence) scalability allows us to predict analytics such as service degradation and perform root cause analysis through metrics, logs, and traces.
I tried many other solutions at work, however, in terms of Nagios, I haven't seen any disruption or downtime.
The setup, however, must be done correctly as incorrect deployment can lead to issues.
Splunk ITSI (IT Service Intelligence) fails if you do not have good hardware requirements.
I would rate the stability of Splunk ITSI (IT Service Intelligence) as a perfect ten; it is an extremely stable tool.
I would appreciate additional features in the next release of Splunk ITSI (IT Service Intelligence) such as cloud infrastructure monitoring including CICDs, Kubernetes, and similar technologies.
On-cloud upgrades are easy, but on-premises upgrades are very painful.
If Splunk ITSI (IT Service Intelligence) could handle real-time call-outs automatically—not just incident creation—this would reduce our dependency on PagerDuty and consolidate processes within Splunk ITSI (IT Service Intelligence).
Splunk ITSI tends to be more expensive compared to some open-source solutions.
I believe the pricing is based on daily volume ingestion.
The pricing reflects usage levels, and compared to others in the market, Splunk ITSI (IT Service Intelligence) provides a reasonable solution.
You can monitor anything.
The predictive analysis can give you proactive information about potential bottlenecks that can occur on applications, desk, storage, SQL servers, databases, or other systems.
One valuable feature is the scheduled maintenance window provided by Splunk ITSI (IT Service Intelligence) because Splunk does not offer this scheduling maintenance feature in the core product, but Splunk ITSI (IT Service Intelligence) helps us with these maintenance reports.
The most beneficial aspect for me is that it is AI-enabled, providing us with very good analytics.
