Free to use and provides valuable monitoring capabilities
Prometheus is a scalable and flexible tool that I can deploy on any cloud platform. It is free to use and provides valuable monitoring capabilities. It allows me to save money by avoiding costs associated with AWS native services like CloudWatch or Amazon Prometheus. The ability to deploy on any cloud platform or environment, including Kubernetes, is a major advantage.
Sunil K R - PeerSpot reviewer
Helps improve our incident response time, and our mean time to resolve, but visibility is limited
In my previous project, I successfully led the end-to-end deployment of a Splunk migration. The process went smoothly thanks in part to Splunk's professional services team. They conducted a thorough assessment, identified all our potential pain points, and developed a tailored solution and migration plan. This comprehensive approach ensured a seamless transition. Our core deployment team consisted of 5 internal members and two specialists from Splunk. Additionally, the project included a project manager and a product owner. We also benefited from the expertise of two professional service consultants and two representatives from the customer's side. An on-site admin architect further provided valuable technical support. Throughout the deployment process, we leveraged support from various resources whenever necessary. This included assistance with configuration changes, deployments, and other related tasks. We also collaborated effectively with our teammates to ensure a smooth and successful implementation.
