Room For Improvement

Enhancing Gremlin with AWS, GCP, machine learning integration and resources can improve usability, despite high cost and complexity.
Splunk ITSI needs better integration, UI, real-time alerts, simplification, scalability, support, and affordability for enhanced user experience.
I think it would be useful to have some integration with Splunk or other log collectors, or maybe in the future, the ability to link Dynatrace or any other observability platform.
Dev Ops To Development (IT)
If we can integrate it with natural language, could we talk to Gremlin Reliability Management Platform and have it configure some of the basic settings so that non-technical persons can also work on Gremlin Reliability Management Platform-like tools?
DEVOPS specialist at a media company with 10,001+ employees
The user interface is great, the integration is smooth, and Gremlin Reliability Management Platform has a fantastic support team that helps us a lot in many cases.
DevOps & Mlops Engineer at a printing company with 1-10 employees
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.
Director at Techpace

Valuable Features

Gremlin Reliability Management Platform enhances system performance with prebuilt tests, automated scheduling, and a user-friendly dashboard for improved uptime.
Splunk ITSI enhances IT management with predictive analytics, customizable dashboards, and integrations for proactive monitoring and swift issue resolution.
There are really two pathways along: fewer incidents because with Gremlin Reliability Management Platform, we can make every part of the infrastructure more solid, and less downtime because we can test more architectures and then things like how to put in high availability clusters.
Dev Ops To Development (IT)
The best feature that Gremlin Reliability Management Platform offers for me is the prebuilt reliability test; I think that is the best feature along with the automated scheduling.
DEVOPS specialist at a media company with 10,001+ employees
One of my best features of Gremlin Reliability Management Platform is the built-in chaos experiments, which gives you the reliability score of your service.
DevOps & Mlops Engineer at a printing company with 1-10 employees
The predictive analysis can give you proactive information about potential bottlenecks that can occur on applications, desk, storage, SQL servers, databases, or other systems.
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
The most beneficial aspect for me is that it is AI-enabled, providing us with very good analytics.

Senior Software Engineer at a sports company with 10,001+ employees
Chaos experiments have revealed weak points and now provide controlled cost-saving tests
The best features of Gremlin Reliability Management Platform are the safe failure injection, which is crucial as we can simulate the failures in a manner that we know these are just dumping tests and not the actual issues. Whether it is the CPU spike or the memory exhaustion, or the network latency, or the server shutdown, server shutdown is one of the most favorite features that I have in Gremlin Reliability Management Platform. The controlled blast radius is another standout feature. The controlled blast radius feature has helped my team in that we actually wanted to target only one specific container, our Docker containers that we deployed. It helped us to conduct tests in a very specific, isolated manner instead of launching a larger test or focusing on hundreds of servers at a time, resulting in very limited impact. Since ours is a very small team, we do not want to impact other servers. This controlled blast radius helped us to only focus on our servers and not impact any other team. Gremlin Reliability Management Platform has positively impacted my organization because before Gremlin Reliability Management Platform, we did not even know how to conduct these chaos engineering tests. We heard about it, but we had no idea of how to do something of that nature. If there are ten servers, ten systems in our architecture and if suddenly something goes down, nobody knew what would happen next. We did not even know how to simulate these types of tests. This lack of confidence has been mitigated by using Gremlin Reliability Management Platform. Now we can confidently test and see which system is the most critical. If this goes down, what happens? How much business valuation are we going to impact? How much loss are we going to incur? All of this is now clearly visible and transparent. Since using Gremlin Reliability Management Platform, we were able to reduce the incidents by six percent after conducting our limited experiments. We were also able to increase the uptime from ninety-eight to ninety-nine, which represents a one percent increase in uptime.

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