Last Event Monitor

Last Event Monitor The app helps Splunk administrators, SOC teams, and SIEM operations teams monitor whether log sources are actively sending data to Splunk. It tracks the latest received event time for each monitored host/index pair and highlights sources that are healthy, delayed, or not sending data. The main problem this app addresses is the lack of simple operational visibility into log source availability. In many Splunk and SIEM environments, log sources may stop sending data because of network issues, forwarder problems, system downtime, configuration changes, or data collection failures. If this is not detected quickly, SOC monitoring, correlation searches, investigations, and compliance reporting may be affected. Last Event Monitor provides dashboards, reports, lookup-based monitoring, automatic host/index discovery, configurable thresholds, exclusion macros, and an optional alert for delayed or missing log sources. The app is useful for: SIEM health checks SOC daily operational control Log collection monitoring Splunk administration Data source availability tracking Investigation of missing or delayed logs
