Lower default active series in agent integration

The agent integration exposes ~700 active series out of the box, most of which may not be useful for just scraping agent metrics. Some extra options should be provided to...

Scrape-time aggregation

1

grafana/agent#393 created a proof of concept of a way to perform aggregation across series at scrape time. I'd like to see this added as a feature.

Work with upstream to make node_exporter integration easier to maintain

grafana/agent#1228 updated our dependency on node_exporter from v1.0.1 to v1.3.1. This ended up being a lot more work than I thought it would be, primarily due to its mapping of...

Manually stored metrics do not have metadata

Samples which are manually written to the WAL (i.e., written outside of the normal scraping process of a metrics instance) do not support metadata being sent over remote write. Metadata...

Failed scrapes prevents series from being deletable

2

When a scrape fails, series written to the Appender will be discarded with a `Rollback`. This breaks the garbage collection check, where it looks to see if a series is...

Metrics: GC stale series separately from truncating WAL

3

## Background Today, Grafana Agent performs a metrics "garbage collection" every 60 minutes (when metrics collection is enabled). The garbage collection process does the following for a specific point in...

CI: automate fuzz tests

`otelcol.exporter.prometheus` was originally released without supporting translating delta aggregation temporalities to cumulative aggregation temporalities; we should add support for it.
