The Splunk Infrastructure Monitoring plugin, which integrates the monitoring capabilities of what was formerly known as SignalFx, is now available for Grafana users with a Cloud account or Enterprise license, allowing them to visualize Splunk and other data sources side-by-side through Grafana dashboards. This plugin is particularly useful for businesses aiming to maintain high availability targets, like a "four nines" SLA, as it provides real-time monitoring and metrics for cloud infrastructure, microservices, and applications, offering high-resolution metrics and real-time analytics. Users can configure the plugin by downloading it from Grafana's plugins page, setting up their data source with a realm name and SignalFx access token, and using SignalFlow queries to populate data. The integration simplifies monitoring Kubernetes clusters and other infrastructures by enabling the use of pre-existing SignalFlow queries and adding variables for filtering data, which helps in creating comprehensive dashboards that can include metrics from Prometheus and SignalFx side-by-side.
