2023/07/08 14:51:12 Starting HTTP server on :2023GET /lmp returns the Locational Marginal Price (LMP) for each node in each region of the MISO network. There are
four kinds of prices:
5m, the realtime 5-minute price1h, the realtime hourly integrated priceexante, the day-ahead ex ante priceexpost, the day-ahead ex post price
There are three components:
LMP, the full location marginal priceMLC, the component of the price due to transmission lossesMCC, the component of the price due to congestion

GET /metrics returns all of the above.
A good starting point:
scrape_configs:
- job_name: 'miso'
scrape_interval: 2m
scrape_timeout: 1m
static_configs:
- targets:
- http://localhost:2023
metric_relabel_configs:
- if: '{__name__=~"^miso_.*"}'
action: labeldrop
regex: "instance|job"/metrics returns unusually large responses, exceeding e.g. VictoriaMetrics' default maximum scrape size of 16 MB.
-promscrape.maxScrapeSize=67108864 seems to work.
As of this writing, miso_price_usd (via /metrics or /lmp) produces 4116 series. This is very high cardinality but
it is also very low churn; series are created or destroyed only as the set of nodes changes, and MISO nodes correspond
to long-lived capital projects like substations or power plants.
