prometheus-pusher

prometheus-pusher aggregates Prometheus metrics from different endpoints and pushes them to pushgateway This component scrapes metrics from CockroachDB and pushes to our gateway.

Run it

./prometheus-runner -config="conf.d"

Usage

See -help.

Configuration

• push_interval
  • Valid sections: [config]
  • Default: 60
  • interval of scraping in seconds
• pushgateway_url
  • Valid sections: [config], [<resource>]
  • Default: ``
  • URL of the pushgateway. If you want to use inverse multiplexing by metric name, you have to include %s in the string. That place will be used by the resolved route destination either from route map file or default_route. Can be configured both in [config] section and separately for each resource.
• route_map
  • Valid sections: [config], [<resource>]
  • Default: n/a
  • Absolute path to the route map file. Can be configured both in [config] section and separately for each resource. Mandatory when using inverse multiplexing
• default_route
  • Valid sections: [config], [<resource>]
  • Default: n/a
  • Default route for metrics with unnamed prefixes. Can include multiple strings separated by , (without spaces). Metrics will be pushed to all the named destinations. Can be configured both in [config] section and separately for each resource. Mandatory when using inverse multiplexing
• host
  • Valid sections: [<resource>]
  • Default: localhost
  • Hostname of the resource
• port mandatory option
  • Valid sections: [<resource>]
  • Default: 0
  • Port of the resource.
• path
  • Valid sections: [<resource>]
  • Default: /metrics
  • The path part of the resource URL.
• ssl
  • Valid sections: [<resource>]
  • Default: false
  • Whether the endpoint is encrypted (HTTPS).
• env_labels
  • Valid sections: [default_env_labels], [service_env_labels]
  • Default: n/a
  • List of ENV variables that will be converted into the labels in all metrics scraped in defined [<resource>]s
  • Final list is a merge of both lists

Example config

[config]
push_interval = 60                 # Default (in seconds)
pushgateway_url = "http://%s.somedomain.com:9092" # Default
route_map = "/path/to/route1.map"
default_route = "prometheus1,prometheus2"

[resource1]
host = "localhost" # Default
path = "/metrics"  # Default
ssl = false        # Default
port = 9111

[resource2]
pushgateway_url = "http://%s.somedomain.com:9091/"
route_map = "/path/to/route2.map"
default_route = "prometheus"
port = 9112

Example route map

go_ prometheus1
go_debug_ prometheus
mem_ prometheus1
