COS Proxy Operator

cos-proxy is a charm facilitating migration from LMA to COS. It is an optional part of the COS Lite bundle.

This Charmed Operator is an intermediate charm that forms as an adapter between the legacy LMA relations and COS relations.

The goal of the cos-proxy operator is to provide a bridge between Reactive charms which integrated with the Reactive Prometheus, Grafana, and Nagios charms, enabling a zero-configuration migration path to COS Lite.

Once deployed in a Reactive/machine Juju model, cos-proxy transparently ties things together, so you can migrate your environment.

The charm create metrics and alerts on the fly for nrpe checkes to be forwarded to prometheus, forwards logs to Loki and dashboards to Grafana.

This charm is:

  • an optional part of the COS Lite bundle
  • intended to be used together with charms implementing the legacy LMA relations.
