Asterisk

Monitor Asterisk PBX — active channels, call volumes, SIP registration status, voicemail counts, and system uptime — using asterisk-exporter.

Pattern: asterisk_exporter → Prometheus scrape → xScaler remote_write

---

Prerequisites

• Asterisk 16+
• ARI (Asterisk REST Interface) enabled
• xScaler tenant credentials (token + tenant ID)

---

Enable ARI

In asterisk/ari.conf:

[general]
enabled = yes
pretty = yes
allowed_origins = *

[xscaler_monitor]
type = user
password = ari_password
read_only = no

---

Option A — Prometheus Exporter

docker run -d \
  -p 9088:9088 \
  -e ASTERISK_URI=http://localhost:8088 \
  -e ASTERISK_USERNAME=xscaler_monitor \
  -e ASTERISK_PASSWORD=ari_password \
  bitergia/asterisk-exporter

Add to prometheus.yml:

scrape_configs:
  - job_name: asterisk
    static_configs:
      - targets: ['localhost:9088']

remote_write:
  - url: https://euw1-01.m.xscalerlabs.com/api/v1/push
    authorization:
      credentials: <token>
    headers:
      X-Scope-OrgID: <tenant-id>

---

Option B — Grafana Alloy

prometheus.scrape "asterisk" {
  targets    = [{"__address__" = "localhost:9088"}]
  forward_to = [prometheus.remote_write.xscaler.receiver]
}

prometheus.remote_write "xscaler" {
  endpoint {
    url = "https://euw1-01.m.xscalerlabs.com/api/v1/push"
    authorization {
      type        = "Bearer"
      credentials = "<token>"
    }
    headers = { "X-Scope-OrgID" = "<tenant-id>" }
  }
}

---

Option C — OpenTelemetry Collector

receivers:
  prometheus:
    config:
      scrape_configs:
        - job_name: asterisk
          static_configs:
            - targets: ['localhost:9088']

processors:
  batch:
    timeout: 10s

exporters:
  otlphttp/xscaler:
    endpoint: https://euw1-01.m.xscalerlabs.com
    headers:
      Authorization: "Bearer <token>"
      X-Scope-OrgID: "<tenant-id>"
    compression: gzip

service:
  pipelines:
    metrics:
      receivers:  [prometheus]
      processors: [batch]
      exporters:  [otlphttp/xscaler]

Logs

Collect Asterisk full log including calls, errors, and AMI events. Add the following to your Alloy config:

local.file_match "asterisk_logs" {
  path_targets = [{
    __address__ = "localhost",
    __path__    = "/var/log/asterisk/full",
    instance    = constants.hostname,
    job         = "integrations/asterisk",
  }]
}

loki.source.file "asterisk_logs" {
  targets    = local.file_match.asterisk_logs.targets
  forward_to = [loki.write.xscaler.receiver]
}

loki.write "xscaler" {
  endpoint {
    url = "https://euw1-01.l.xscalerlabs.com/api/v1/logs/push"

    http_client_config {
      authorization {
        type        = "Bearer"
        credentials = env("XSCALER_TOKEN")
      }
    }

    headers = { "X-Scope-OrgID" = env("XSCALER_TENANT_ID") }
  }
}
