Analysis of sealing messages aggregated #18
Description
we track the receive of sealing messages for each validator in the metrics interface, therefore this information is available in prometheus and grafana as well.
The real interesting information to see, is what node has received how many sealing messages for the active block being produced.
Therefore we could identify the Nodes that should be able to create a Block, or to figure out what sealing messages are missing.
This could also be just a "momentary" information, just delivering the "latest" news of the given time range, for example as bar diagram.
