Prometheus is a systems and service monitoring system. It collects metrics
from configured targets at given intervals, evaluates rule expressions,
displays the results, and can trigger alerts if some condition is observed
to be true.
Prometheus' main distinguishing features as compared to other monitoring
systems are:
- a multi-dimensional data model (timeseries defined by metric name and
set of key/value dimensions)
- a flexible query language to leverage this dimensionality
- no dependency on distributed storage; single server nodes are autonomous
- timeseries collection happens via a pull model over HTTP
- pushing timeseries is supported via an intermediary gateway
- targets are discovered via service discovery or static configuration
- multiple modes of graphing and dashboarding support
- support for hierarchical and horizontal federation

FreshPorts has no man page information for this port.
===> The following configuration options are available for prometheus-2.55.1_1:
DOCS=on: Build and/or install documentation
===> Use 'make config' to modify these settings
TLS 1.0 and 1.1 disabled by default client-side.
Prometheus users can override this with the min_version parameter of tls_config.
Certificates signed with the SHA-1 hash function are rejected. This doesn't apply to self-signed root certificates.
If upgrading from < 2.20:
promtool: Changed rule numbering from 0-based to 1-based when reporting rule errors.
Added `prometheus_remote_storage_read_queries_total` counter and
`prometheus_remote_storage_read_request_duration_seconds` histogram, removed
`prometheus_remote_storage_remote_read_queries_total` counter.
Added buckets for longer durations to
`prometheus_remote_storage_sent_batch_duration_seconds` histogram.
WAL compression is enabled by default.
If upgrading from < 2.15:
The `prometheus_sd_kubernetes_cache_*` metrics were removed.
The `prometheus_sd_kubernetes_workqueue_latency_seconds` and
`prometheus_sd_kubernetes_workqueue_work_duration_seconds` now show correct
values in seconds.
The `query` label on `prometheus_remote_storage_*` metrics has been changed to
`remote_name` and `url`.
If upgrading from < 2.11:
The `prometheus_tsdb_wal_reader_corruption_errors` metric was renamed to
`prometheus_tsdb_wal_reader_corruption_errors_total`.
If upgrading from < 2.8:
The `prometheus_tsdb_storage_blocks_bytes_total` metric is now
`prometheus_tsdb_storage_blocks_bytes`.
If upgrading from < 2.7:
The `storage.tsdb.retention` flag has been deprecated in Prometheus 2.7.0.
Users of this flag will want to update their configuration to use the newer
`storage.tsdb.retention.time` flag.
If upgrading from < 2.3:
Users of `marathon_sd` should now use `auth_token` and `auth_token_file` for
token-based authentication instead of `bearer_token` and `bearer_token_file`
respectively.
Metric names for the HTTP server metrics were changed.
