Log_to_metric convert mcs to seconds in field

[Manniac07]

Is my field syntax correct. Or is there a better way to convert mcs to second
wfm_scheduleViewerAction_latency-prod:
type: log_to_metric inputs:

• filter_wfm_scheduleVtewerAction_prod_message
  metrics:
• type: histogram
  field: http.request.request_time_mcs/1000000
  name: nice_apache_access_agent_adherence increment_by_value: true namespace: vector

Unfortunately, the configuration for log_to_metric is static; you can't have an expression for the field like you have. The workaround would be to use remap to divide the value before feeding it into log_to_metric.

@jszwedko Like this?

-filter_wfm_scheduleViewerAction_test_message
type: "remap"
source: . = parse_json!(.message)
.http.request.request_time_mcs =to_float!(http.request.request_time_mcs) / 1000000
