🎵 paas-billing 2: Auditor Boogaloo 🎵

Overview

A Golang application that scrapes Cloud Controller's /v2/events endpoint for Audit Events and stores them in a Postgres database.

To understand how to run this and solve issues, see the RUNBOOK.

Installation

You will need:

• Go v1.20

To build the application run the default make target:

make

You should then get a binary in bin/paas-auditor.

Configuration

paas-auditor takes the following environment variables:

Variable name	Type	Required	Default	Description
APP_ROOT	string	no	$PWD	absolute path to the application source to discover assets at runtime
DATABASE_URL	string	yes		Postgres connection string
CF_API_ADDRESS	string	yes		Cloud Foundry API endpoint
CF_CLIENT_ID	string	yes		Cloud Foundry client id
CF_CLIENT_SECRET	string	yes		Cloud Foundry client secret
SPLUNK_API_KEY	string	no		Optional API key for Splunk, if provided it will send events to Splunk HEC
SPLUNK_HEC_ENDPOINT_URL	string	no		Optional URL for Splunk, if provided it will send events to Splunk HEC
DEPLOY_ENV	string	no		populates the source field in Splunk
PORT_ENV	string	no		port on which to listen, to serve metrics

Note: in development you can use CF_USERNAME and CF_PASSWORD instead of CF_CLIENT_ID CF_CLIENT_SECRET to allow it to log into Cloud Foundry

Metrics

paas-auditor exposes the following metrics via /metrics:

Metric	Description
cf_audit_event_collector_collect_duration_total	Number of seconds spent collecting events by CF Audit Event Collector
cf_audit_event_collector_errors_total	Number of errors encountered by CF Audit Event Collector
cf_audit_event_collector_events_collected_total	Number of events collected and saved to the DB by CF Audit Event Collector
cf_audit_events_to_splunk_shipper_errors_total	Number of errors encountered by CF Audit Events to Splunk shipper
cf_audit_events_to_splunk_shipper_events_shipped_total	Number of CF audit events shipped to Splunk by CF Audit Events to Splunk shipper
cf_audit_events_to_splunk_shipper_latest_event_timestamp	Unix epoch seconds of most recent event shipped to Splunk
cf_audit_events_to_splunk_shipper_ship_duration_total	Number of seconds spent shipping events by CF Audit Events to Splunk Shipper
informer_cf_audit_events_total	Number of CF audit events in the database (This number is approximate, and depends on Postgres reltuples)
informer_latest_cf_audit_event_timestamp	Unix epoch seconds of most recent event in the database
