Let’s set up a basic demonstration with two nodes, the first acting as a placeholder load with Telegraf installed - the “Workload”, and the second acting as our data visualization system - the “Monitor”. For this LMA stack, visualization is handled via Grafana and email/pager alerts are generated via the Prometheus Alertmanager plugin. Prometheus works as a hub, polling data from different Telegraf nodes and sending it to various outputs, including persistent storage. Its plugin system permits export of data in any arbitrary format for this system we collect the data in a central data manager called Prometheus. Telegraf collects metrics from the operating system, running software, and other inputs. Architectural OverviewĬanonical’s LMA stack involves several discrete software services acting in concert, including: Your LMA stack will help point out issues in load, networking, and other resources before it becomes a failure point. Logging, Monitoring, and Alerting (LMA) is a collection of tools used to guarantee the availability of your running infrastructure. While the current LMA will continue to work for the time being, most users are recommended to instead consider COS.
