Open Liberty in Docker on a Raspberry Pi

Open Liberty is small and lightweight so it was never a problem to fit it on the original Raspberry Pi back in 2012. I set off on a mission to see how easy it is to get a Raspberry Pi-compatible Docker image of Open Liberty.

Get alerts from your Open Liberty apps in Slack using Prometheus Alertmanager

Set up Prometheus Alertmanager to fire alerts to a specified Slack channel to notify you when, for example, your app's heap usage is too high. Configure Prometheus with alerting rules to receive certain alerts from Open Liberty, then configure Prometheus Alertmanager to pass those alerts to a Slack channel.

New Kibana dashboard visualizations to spot potential problems in your Liberty servers

Log aggregation and analysis are essential in order to monitor and quickly troubleshoot problems in your server. You can use the popular Elastic Stack tools to aggregate and analyze the log events then display those log events in dashboards such as Kibana to help you spot potential problems in your Liberty server in real time. We have added new visualizations to our sample Kibana dashboards to help you.
