SYNOPSIS
prometheus [<flags>]
DESCRIPTION
The Prometheus monitoring server
OPTIONS
-h, --help
Show context-sensitive help (also try --help-long and --help-man).
--version
Show application version.
--config.file="/etc/prometheus/prometheus.yml"
Prometheus configuration file path.
--web.listen-address="0.0.0.0:9090"
Address to listen on for UI, API, and telemetry.
--web.config.file=""
[EXPERIMENTAL] Path to configuration file that can enable TLS or authentication.
--web.read-timeout=5m
Maximum duration before timing out read of the request, and closing idle connections.
--web.max-connections=512
Maximum number of simultaneous connections.
--web.external-url=<URL>
The URL under which Prometheus is externally reachable (for example, if Prometheus is served via a
reverse proxy). Used for generating relative and absolute links back to Prometheus itself. If the
URL has a path portion, it will be used to prefix all HTTP endpoints served by Prometheus. If
omitted, relevant URL components will be derived automatically.
--web.route-prefix=<path>
Prefix for the internal routes of web endpoints. Defaults to path of --web.external-url.
--web.local-assets="/usr/share/prometheus/web/"
Path to static asset/templates directory.
--web.user-assets=<path>
Path to user asset directory, available at /user.
--web.enable-lifecycle
Enable shutdown and reload via HTTP request.
--web.enable-admin-api
Enable API endpoints for admin control actions.
--web.enable-remote-write-receiver
Enable API endpoint accepting remote write requests.
--web.console.templates="/etc/prometheus/consoles"
Path to the console template directory, available at /consoles.
--web.console.libraries="/etc/prometheus/console_libraries"
Path to the console library directory.
--web.page-title="Prometheus Time Series Collection and Processing Server"
Document title of Prometheus instance.
--web.cors.origin=".*"
Regex for CORS origin. It is fully anchored. Example: 'https?://(domain1|domain2).com'
--storage.tsdb.path="/var/lib/prometheus/metrics2/"
Base path for metrics storage. Use with server mode only.
--storage.tsdb.retention=STORAGE.TSDB.RETENTION
[DEPRECATED] How long to retain samples in storage. This flag has been deprecated, use
"storage.tsdb.retention.time" instead. Use with server mode only.
--storage.tsdb.retention.time=STORAGE.TSDB.RETENTION.TIME
How long to retain samples in storage. When this flag is set it overrides
"storage.tsdb.retention". If neither this flag nor "storage.tsdb.retention" nor
"storage.tsdb.retention.size" is set, the retention time defaults to 15d. Units Supported: y, w,
d, h, m, s, ms. Use with server mode only.
--storage.tsdb.retention.size=STORAGE.TSDB.RETENTION.SIZE
Maximum number of bytes that can be stored for blocks. A unit is required, supported units: B, KB,
MB, GB, TB, PB, EB. Ex: "512MB". Based on powers-of-2, so 1KB is 1024B. Use with server mode only.
--storage.tsdb.use-lockfile
Create a lockfile in data directory. Use with server mode only.
--storage.tsdb.head-chunks-write-queue-size=0
Size of the queue through which head chunks are written to the disk to be m-mapped, 0 disables the
queue completely. Experimental. Use with server mode only.
--storage.agent.path="/var/lib/prometheus/data-agent/"
Base path for metrics storage. Use with agent mode only.
--storage.agent.wal-compression
Compress the agent WAL. Use with agent mode only.
--storage.agent.retention.min-time=STORAGE.AGENT.RETENTION.MIN-TIME
Minimum age samples may be before being considered for deletion when the WAL is truncated Use with
agent mode only.
--storage.agent.retention.max-time=STORAGE.AGENT.RETENTION.MAX-TIME
Maximum age samples may be before being forcibly deleted when the WAL is truncated Use with agent
mode only.
--storage.agent.use-lockfile
Create a lockfile in data directory. Use with agent mode only.
--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. This limit is ignored for streamed response types. Use with server mode only.
--storage.remote.read-concurrent-limit=10
Maximum number of concurrent remote read calls. 0 means no limit. Use with server mode only.
--storage.remote.read-max-bytes-in-frame=1048576
Maximum number of bytes in a single frame for streaming remote read response types before
marshalling. Note that client might have limit on frame size as well. 1MB as recommended by
protobuf by default. Use with server mode only.
--rules.alert.for-outage-tolerance=1h
Max time to tolerate prometheus outage for restoring "for" state of alert. Use with server mode
only.
--rules.alert.for-grace-period=10m
Minimum duration between alert and restored "for" state. This is maintained only for alerts with
configured "for" time greater than grace period. Use with server mode only.
--rules.alert.resend-delay=1m
Minimum amount of time to wait before resending an alert to Alertmanager. Use with server mode
only.
--alertmanager.notification-queue-capacity=10000
The capacity of the queue for pending Alertmanager notifications. Use with server mode only.
--query.lookback-delta=5m
The maximum lookback duration for retrieving metrics during expression evaluations and federation.
Use with server mode only.
--query.timeout=2m
Maximum time a query may take before being aborted. Use with server mode only.
--query.max-concurrency=20
Maximum number of queries executed concurrently. Use with server mode only.
--query.max-samples=50000000
Maximum number of samples a single query can load into memory. Note that queries will fail if they
try to load more samples than this into memory, so this also limits the number of samples a query
can return. Use with server mode only.
--enable-feature=
Comma separated feature names to enable. Valid options: agent, exemplar-storage, expand-external-
labels, memory-snapshot-on-shutdown, promql-at-modifier, promql-negative-offset, promql-per-step-
stats, remote-write-receiver (DEPRECATED), extra-scrape-metrics, new-service-discovery-manager,
auto-gomaxprocs, no-default-scrape-port, native-histograms. See

--log.level=info
Only log messages with the given severity or above. One of: [debug, info, warn, error]
--log.format=logfmt
Output format of log messages. One of: [logfmt, json]
