Mirantis StackLight LMA is a comprehensive Logging, Monitoring, and Alerting software suite designed to provide a unified operational view, or "single pane of glass," for managing cloud environments. By leveraging integrated open-source tools such as Prometheus for time-series metrics and monitoring, and OpenSearch for log aggregation and analysis, StackLight delivers critical insights into the health and performance of the cloud infrastructure and its services, supporting effective day-to-day operations and maintenance activities.

This centralized approach significantly speeds up troubleshooting and enables proactive identification of potential issues before they impact end-users. Consequently, it enhances overall system reliability and simplifies the complexities of cloud management.

In Mirantis k0rdent Enterprise, StackLight is distributed as Kubernetes Operator--a CustomResourceDefinition (stacklights.monitoring.mirantis.com) and corresponding controller--and is installed as a Helm chart. For Mirantis k0rdent Virtualzation (KubeVirt) as part of Mirantis k0rdent Enterprise, StackLight is distributed as a ServiceTemplate object.

StackLight consists of the following components:

Prometheus: Provides a time-series database
Prometheus Relay: Prometheus API High Availability proxy
Grafana: For timeseries visualization
AlertManager: Notifications system
Alerta: Provides alerts visualization
cAdvisor: Exports metrics
Node Exporter: OS metrics collector
Blackbox exporter: Provides endpoint probes
Kube-state-metrics: K8s objects metrics collector
OpenSearch: A database for system and audit logs
OpenSearch Dashboards: Provides logs visualization
Fluentd: A tool for logs collecting and processing
Spilo: A High Availability Postgresql solution using Patroni (as a backend for Alerta and Grafana)
