Exporting metrics to Prometheus

Metrics in MITIGATOR are stored in Graphite. It is possible to export metrics to Prometheus via graphite_exporter.

To organize sending, you need to deploy and configure graphite_exporter
(the main configuration file and the configuration file for metrics matching), then configure sending metrics to graphite_exporter.

Brief sequence of actions:

1. Writing a metric compliance configuration for specific needs.
2. Deploying graphite_exporter with this configuration.
3. Setting up data sending in the MITIGATOR system.

graphite_exporter metrics matching configuration

A list of metrics with a short description is available by link.

Configuration example:

- match: ^mitigator\.elements\.extInputCounter\.(.*)$
  name: extInputCounter
  labels:
    unit: $1

- match: ^mitigator\.elements\.policy_(\d+)\.inputCounter\.(.*)$
  name: inputCounter
  labels:
    policy: $1
    unit: $2

- match: ^mitigator\.ports\.((?:int|ext)\d+)\.opackets$
  name: opackets
  labels:
    port: $1

MITIGATOR Setup

In docker-compose.override.yml add:

version: "2.2"
services:
  fwstats:
    environment:
      FWSTATS_GRAPHITE_ADDRESS: "carbon-clickhouse.mitigator:2003,some_server:9109"

Where some_server:9109 is the address and port of the graphite_exporter; the first value must be saved. You can specify multiple servers if you wish.

Apply parameters:

docker-compose up -d fwstats
