Prometheus metrics explanations

I’m looking at the prometheus metrics that algod exports. The “algod_” metrics have generally useful help text but the “ledger_” metrics help text is a little sparse. I’m wondering about these two in particular:

    var ledgerGetblockCount = metrics.NewCounter("ledger_blockq_getblock_count", "calls")
    var ledgerGetblockMicros = metrics.NewCounter("ledger_blockq_getblock_micros", "µs spent")

Would those be counters that tell me how many blocks have been requested and how long we spend responding to such requests? That’s kind of what the data looks like when I observe it in Prometheus/Grafana.

In particular, I’m curious about this in terms of an algod instance that is a source of blocks for the Indexer-v2.
