Sentry Exporter for prometheus

Parse sentry stats API and provide metrics to prometheus.

There are two available modes:

DAEMON mode

Start webserver providing HTTP access to gathered metrics. Metrics are stored in file on disk and is regenerated every 60s (by default).

This mode will be enabled after -daemon-mode parameter is set. This mode uses parameters:

• -i <int> ...interval in seconds between reading stats from sparkpost (Example 120)
• -p <string> ...http endpoint listening port (Example :9091)
• -read-token=<string> ...token that have to be sent by prometheus to read metrics (Example -read-token=MySECRET123 mean that request should looks like /_metrics?token=MySECRET123)

SIMPLE mode

Get metrics and generate file in promfile format to defined path and exits. It works well with node_exporter and defined metrics dir.

This mode ignores parameters:

• -i
• -p
• -read-token

Metrics example

# HELP sentry_received_events_count Hourly received amount of events grouped by project-slug.
sentry_received_events_count{project="fe-landing"} 6
sentry_received_events_count{project="fe-user_area"} 1

Program help

  -daemon-mode
        Run in daemon mode and server results via HTTP protocol
  -i int
        Interval in seconds between gathering data from sentry (default 60)
  -o string
        Path to file where metrics should be saved (default "tmp_out.prom")
  -p string
        Listening port (default ":9091")
  -read-token string
        Read token for HTTP endpoint, if empty, no autentication is required

Program accept ENV vars

• SENTRY_TOKEN - required parameter
• INTERVAL - same to -i parameter
• PORT - same to -p parameter
• METRICS_FILE - same to -o parameter
• READ_TOKEN - same to -read-token parameter
