Blackbox ExporterBlackbox exporter is a prometheus exporter which can probe endpoints via http/https, icmp, etc. It's extremely simple to setup and can be used to monitor the status of various endpoints (which could be web applications, REST endpoints, etc.). We've already setup Node_Exporternode_exporter is a prometheus exporter which monitors hardware and 'nix OS metrics. It runs on a port exposed to prometheus and prometheus can then query it and get a (large) ranger of metrics for whatever machine is running node_exporter. GrafanaGrafana is a great platform for visualising data and metrics from large data sets. It can connect with a very large number of data sources and has native (built-in) prometheus support, which makes it extremely easy to integrate prometheus and provides an attractive and versatile front-end to view various prometheus metrics. |
