- --storage.tsdb.path="/var/lib/prometheus/metrics2/"

- --storage.tsdb.retention=15d
- [DEPRECATED] How long to retain samples in storage. This flag has been
deprecated, use "storage.tsdb.retention.time" instead
- --storage.tsdb.retention.time=15d
- How long to retain samples in storage. Overrides
"storage.tsdb.retention" if this flag is set to anything other
than default.
- --storage.tsdb.retention.size=0
- [EXPERIMENTAL] Maximum number of bytes that can be stored for blocks.
Units supported: KB, MB, GB, TB, PB. This flag is experimental and can be
changed in future releases.
- --storage.tsdb.use-lockfile

- --storage.remote.flush-deadline=<duration>
- How long to wait flushing sample on shutdown or config reload.
- --storage.remote.read-sample-limit=5e7
- Maximum overall number of samples to return via the remote read interface,
in a single query. 0 means no limit.
- --storage.remote.read-concurrent-limit=10
- Maximum number of concurrent remote read calls. 0 means no limit.

- --query.max-concurrency=20
- Maximum number of queries executed concurrently.
- --query.max-samples=50000000
- Maximum number of samples a single query can load into memory. Note that
queries will fail if they would load more samples than this into memory,
so this also limits the number of samples a query can return.
- --web.cors.origin=".*"
- Regex for CORS origin. It is fully anchored. Eg.
'https?://(domain1|domain2).com'
- --log.level=info
- Only log messages with the given severity or above. One of: [debug, info,
