Send selected metrics with write option

[Mohan Nagandlla]

Hi team 

I am sending all the metrics to the influxdb by using remote write option.  So I just want to sent a specified metrics only how can do that.

Hi,

In section "remote_write:", where you most likely configure your influxdb setup, you can add some "write_relabel_configs:".

For example, this would send only all metrics with "prefix:"

write_relabel_configs:
    - source_labels: ['__name__']
      regex: (prefix:.*)
      action: keep

So, you keep or drop based on labels. You may combine with recording rules:

1. define recording rules with some known prefix, and use those rules to perform aggregations
   
2. define write_relabel_configs as above to send only metrics with "prefix:" so only the aggregated metrics
