ROI

Sentiment score
7.1
Organizations experienced diverse returns with Datadog, reporting time savings, reduced blindspots, enhanced visibility, integration benefits, and efficiency improvements.
Sentiment score
7.8
Splunk Observability Cloud enhances visibility and efficiency, resulting in faster resolutions, reduced costs, and improved KPI performance for users.
Using Splunk has saved my organization about 30% of our budget compared to using multiple different monitoring products.
Anyone working in front-end management should recognize the market price to see the true value of end-user monitoring.
 

Customer Service

Sentiment score
7.3
Datadog customer service is responsive and professional, offering proactive support despite occasional delays in their ticket system.
Sentiment score
7.4
Splunk Observability Cloud support is responsive but needs faster response times and deeper expertise for improved service quality.
They often require multiple questions, with five or six emails to get a response.
Support from Splunk is not very helpful because Splunk doesn't have a dedicated APM; they only have one APM engineer in Korea.
They did respond to us, but they did not explicitly inform us about the feature's absence.
 

Scalability Issues

Sentiment score
7.6
Datadog scales efficiently with diverse technologies, though rising costs and limited API capabilities remain concerns for some users.
Sentiment score
7.8
Splunk Observability Cloud offers scalable and flexible solutions, though concerns about cost and complexity persist among users.
We've used the solution across more than 250 people, including engineers.
I would rate its scalability a nine out of ten.
The issue is mainly about pricing because if they want to monitor more, it costs money.
 

Stability Issues

Sentiment score
8.0
Datadog offers reliable performance with minimal downtime, resolving integration issues promptly and maintaining consistent uptime even during peak traffic.
Sentiment score
8.3
Splunk Observability Cloud is mostly stable and reliable, with users experiencing minimal issues and frequent alert notification management.
I would rate its stability a nine out of ten.
We rarely have problems accessing the dashboard or the page.
Unlike NetScout or regular agents for APM, RUM has many problems during the POC phase because customer environments vary widely.
 

Room For Improvement

Datadog struggles with performance, usability, and cost issues, requiring improvements in integration, documentation, and user interface.
Users seek better integration, customization, scalability, and performance in Splunk Observability Cloud, alongside improved support and navigation features.
The documentation is adequate, but team members coming into a project could benefit from more guided, interactive tutorials, ideally leveraging real-world data.
There should be a clearer view of the expenses.
There is room for improvement in the alerting system, which is complicated and has less documentation available.
Improvements in dashboard configuration, customization, and artificial intelligence functionalities are desired.
Customers sometimes need to create specific dashboards, particularly for applicative metrics such as Java and process terms.

Datadog's pricing model is flexible yet can be costly, requiring careful planning to optimize its comprehensive features and avoid surprises.
Splunk Observability Cloud's pricing is competitive and flexible, offering annual licenses with a 14-day free trial for evaluation.
The setup cost for Datadog is more than $100.
Splunk is a bit expensive since it charges based on the indexing rate of data.
It appears to be expensive compared to competitors.
Splunk is a little expensive, however, it is in line with the current market pricing.

Featured Reviews

Kevin Palmer - PeerSpot reviewer
Useful log aggregation and management with helpful metrics aggregation
Datadog provides us value in three major ways: First, Datadog provides best-in-class functionality in many, if not all, of the products to which we subscribe (infrastructure, APM, log management, serverless, synthetics, real user monitoring, DB monitoring). In my experience with other tools that provide similar functionality, Datadog provides the largest feature set with the most flexibility and the best performance. Second, Datadog allows us to access all of those services in one place. Having to learn and manage only one tool for all of those purposes is a major benefit. Third, Datadog provides significant connectivity between those services so that we can view, summarize, organize, translate and correlate our data with maximum effect. Not needing to manually integrate them to draw lines between those pieces of information is a huge time savings for us.
Lakshmi Padaga - PeerSpot reviewer
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.
