CitiGroup, with a vast global presence, faces significant IT challenges due to its complex infrastructure and demands for greater efficiency. To address these issues, CitiGroup's IT teams implemented an integrated monitoring system using the Elastic Stack to centralize data, configure agents, and reduce costs. This system ingests vast amounts of data daily to monitor tool performance, offering a centralized data store and enabling data governance with role-based access control. Elasticsearch facilitates data storage, retrieval, and analysis, allowing for advanced search analytics and visualization. The system also supports container infrastructure monitoring, delivering comprehensive and real-time insights into application health through Kibana dashboards, which are used for audit findings, alert management, and various operational tasks. This setup empowers CitiGroup to monitor its IT infrastructure effectively, providing the necessary data to management for informed decision-making and operational improvements.
