Room For Improvement

Gremlin could improve through AI-driven analysis, better user onboarding, expanded service integrations, enhanced UI, and additional learning resources.
Splunk ITSI faces complexity and cost issues, needing better documentation, integrations, monitoring, predictive analytics, and improved usability features.
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) at a non-tech company with self employed
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?

Valuable Features

Gremlin enhances efficiency with test suites, fault injection, risk detection, and reliability insights, boosting uptime and customer satisfaction.
Splunk ITSI is valued for intelligent alerting, predictive analytics, and integration capabilities, enhancing visibility and reducing incident noise.
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) at a non-tech company with self employed
We fix failures even before they occur, which is basically proactive risk detection and risk mitigation.

VP Global at a tech vendor with 10,001+ employees
Proactive failure testing has increased confidence and reliability across complex microservices
There are certain areas where I think Gremlin Reliability Management Platform can improve. I would certainly add features related to AI and GenAI for recommendations. While dependency identification works well seamlessly, deeper dependency intelligence is lacking. When you have deeper dependencies, reliability management can struggle with identifying those deeper dependency intelligences. Having the intelligence to deeply analyze dependencies will be very helpful. Regarding reliability scores, while those scores are good, having more actionable reliability scores is something I would recommend adding to the existing system. Initially, when I started with Gremlin Reliability Management Platform certification programs, I completed two certifications with Gremlin—one professional and another practitioner. While that certification has helped me, an easier onboarding and learning curve for bringing people into this program can be adjusted. That is one current gap I see. If you really look at the cost-benefit visibility, it is not very evident by using Gremlin Reliability Management Platform. If Gremlin Reliability Management Platform could help realize that and bring in visibility regarding the cost versus the benefit, that is the reason I provide a score less than ten. From a standpoint of simulating complex real-world failures, I believe there is still a gap concerning gap identification. Currently, Gremlin Reliability Management Platform mainly focuses on infrastructure-level failures and does not really simulate business logic failures, data corruption scenarios, or potential failures across regions. One of the key elements needing improvement with Gremlin Reliability Management Platform is the limited team workflow integration I see in my organization. Collaboration and limited team workflow integration are areas I would highlight as needing improvement.

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.
