The key point here is that Netdata can export metrics from its internal DB or can send metrics _as-collected_ by specifying the `source=as-collected` URL parameter like so. <http://localhost:19999/api/v1/allmetrics?format=prometheus&help=yes&types=yes&source=as-collected> If you choose to use this method you will need to use Prometheus's set of functions here: <https://prometheus.io/docs/querying/functions/> to obtain useful metrics as you are now dealing with raw counters from the system. For example you will have to use the `irate()` function over a counter to get that metric's rate per second. If your graphing needs are met by using the -metrics returned by NetData's internal database (not specifying any source= URL parameter) then use that. If you find +metrics returned by Netdata's internal database (not specifying any source= URL parameter) then use that. If you find limitations then consider re-writing your queries using the raw data and using Prometheus functions to get the desired chart. |
