We (wavefront) have modified the fdbcli (under fdb version 5.2) a bit, so that we can run a command to parse the returned json object and turn into wavefront supported format metrics. (I think one of the benefits we have is to translate non-friendly metrics into human readable values and add additional information like host /process id/ machine id as point tag)
fdbcli —exec "status wavefront"
fdbcli —exec "status wavefront" | nc "wavefront proxy address"
Feel like that could be helpful for the teams which deploying FoundationDB at scale and you can find sample output in the attachment below.
