Elastic Observability seems to have a good scale-out capability.

Syed Waqar Uddin

Chief Cloud Architect at a tech services company with 11-50 employees

Elastic Observability is easy in deployment in general for small scale, but when you deploy it at a really large scale, the complexity comes with the customizations.

Splunk ITSI is stable and reliable, managing large datasets efficiently, with minor challenges mainly during updates and configuration.

There are some bugs that come with each release, but they are keen always to build major versions and minor versions on time, including the CVE vulnerabilities to fix it.

Assistant Vice President at QualityKiosk Technologies Pvt. Ltd.

It is very stable, and I would rate it ten out of ten based on my interaction with it.

Adelina Craciun

Product Owner at Swisscom

Room For Improvement

Elastic Observability needs automation, AI, and customization improvements, addressing complex deployment, market presence, metrics, licensing, and usability issues.

Splunk ITSI needs better integration, user interface, predictive analytics, machine learning, real-time alerting, automated response, and user support.

For instance, if you have many error logs and want to create a rule with a custom query, such as triggering an alert for five errors in the last hour, all you need to do is open the AI bot, type this question, and it generates an Elastic query for you to use in your alert rules.

Lakshmi Bodepu

Senior Consultant at Skillfield

It lacked some capabilities when handling on-prem devices, like network observability, package flow analysis, and device performance data on the infrastructure side.

Senior Technical Sales at a tech vendor with 1,001-5,000 employees

Some areas such as AI Ops still require data scientists to understand machine learning and AI, and it doesn't have a quick win with no-brainer use cases.

Assistant Vice President at QualityKiosk Technologies Pvt. Ltd.

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.

Ahmed Naguib

Director at Techpace

Splunk ITSI could benefit from including more features that other solutions support, such as vulnerability management modules.

Senior consultant at a tech services company with 51-200 employees

I believe the installation process should be more uniform, meaning it could be deployed across all components to avoid post-installation issues.

Setup Cost

Elastic Observability provides competitive pricing, benefiting large enterprises with comprehensive licensing, but may be costly for smaller users.

Splunk ITSI is a costly but comprehensive tool, valued for its observability despite complex licensing and high pricing.

The license is reasonably priced, however, the VMs where we host the solution are extremely expensive, making the overall cost in the public cloud high.

Adelina Craciun

Product Owner at Swisscom

Elastic Observability is cost-efficient and provides all features in the enterprise license without asset-based licensing.

Syed Waqar Uddin

Chief Cloud Architect at a tech services company with 11-50 employees

Observability is actually cheaper compared to logs because you're not indexing huge blobs of text and trying to parse those.

Valuable Features

Elastic Observability excels with flexible integration, powerful search, scalability, real-time insights, affordability, and robust support, enhancing efficiency.

Splunk IT Service Intelligence enhances incident management with agile data handling, advanced analytics, and effective troubleshooting features for quick issue resolution.

The most valuable feature is the integrated platform that allows customers to start from observability and expand into other areas like security, EDR solutions, etc.

Syed Waqar Uddin

Chief Cloud Architect at a tech services company with 11-50 employees

the most valued feature of Elastic is its log analytics capabilities.

reviewer708360

Senior Technical Sales at a tech vendor with 1,001-5,000 employees

All the features that we use, such as monitoring, dashboarding, reporting, the possibility of alerting, and the way we index the data, are important.

The predictive analysis can give you proactive information about potential bottlenecks that can occur on applications, desk, storage, SQL servers, databases, or other systems.

Ahmed Naguib

Director at Techpace

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.

Senior Consultant at a consultancy with 10,001+ employees

Splunk ITSI allows for integration with threat intelligence, enabling my organization to correlate more than two events for generating alerts.

Featured Reviews

Has provided powerful customization for unique monitoring needs but needs more out-of-the-box capabilities

Assistant Vice President at QualityKiosk Technologies Pvt. Ltd.

In my opinion, the best features of Elastic Observability are their flexibility to integrate with other existing systems and the ability to build a unified monitoring tool that can integrate with existing ones and end-to-end user journeys which require a lot of customizations. The greatest feature in Elastic is the ability to customize. This is similar to my comments about customizable dashboards in Elastic because it's visible to the analyst. However, it's very great. Customizing these dashboards can meet the customer's specific use cases and specific stories that they have in their environment, their special environment that doesn't look like other environments. The dashboarding in Elastic is highly customizable to the level of logos. If the customer wants his company logo in the dashboard, it can be done.

Service health has been monitored and visual insights support proactive telecom operations

Senior Consultant at a consultancy with 10,001+ employees

The installation process is the first aspect I dislike about Splunk ITSI (IT Service Intelligence). If you do not configure it correctly, you will encounter issues in the search head. Because we use a distributed environment where each component has its own specific roles, installation is critical and requires careful attention. Splunk ITSI (IT Service Intelligence) is built with many applications. It is a compressed file, and when you extract the Splunk ITSI (IT Service Intelligence) app, you receive approximately 19 apps. Some applications, add-ons, and packages must be installed on specific components. If you do not configure an application correctly, it will not work. Sometimes we encounter issues during installation because of this complexity. I believe the installation process should be more uniform, meaning it could be deployed across all components to avoid post-installation issues. Sometimes after installation, you receive errors, and users cannot access Splunk ITSI (IT Service Intelligence). We have experienced this type of issue due to installation errors. I believe there is currently room for improvement regarding scalability. 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) should have a lightweight version to address these concerns. I would rate current scalability as medium.
