Enabling support for OpenTSDB
This module sends all metrics to OpenTSDB server. You need something like Grafana for graphing.
What you don't get
Pretty graphs, this is why at present you need Grafana. You need to build your own graphs within Grafana.
RRD will continue to function normally so LibreNMS itself should continue to function normally.
You can add the following to your config:
lnms config:set opentsdb.enable true lnms config:set opentsdb.host '127.0.0.1' lnms config:set opentsdb.port 4242
The same data than the one stored within rrd will be sent to OpenTSDB and recorded. You can then create graphs within Grafana to display the information you need.
