Metrics Issues #4
Description
Issue: Metrics Not Reporting Correctly for Substreams Sink Noop
The substreams_sink_noop_chain_head_block_number metric is consistently returning a value of 0. Additionally, the substreams_sink_noop_backprocessing_completion metric also remains at 0, even when the substreams_sink_noop_head_block_reached metric shows 1, indicating that the head block has been reached. Could you clarify at which point this metric should reflect meaningful values?
Enhancement Request: Labeling for Metrics
To improve observability and ease of dashboard creation, it would be highly beneficial to include a native label, such as app = substreams_sink, across all sink-related metrics (similar to the blockmeta label). This would greatly aid in distinguishing between native substreams and substreams sinks when building dashboards with common metrics. .i.e. head_block_time_drift
