Jenkins

Monitor Jenkins build results, durations, queue lengths, executor utilisation, and node health.

Key Metrics

Metric	Description
jenkins_builds_total	Total builds executed
jenkins_builds_success_total	Successful builds
jenkins_builds_failed_total	Failed builds
jenkins_builds_duration_milliseconds_sum	Cumulative build duration

Prerequisites

• Jenkins 2.x
• Prometheus Metrics Plugin installed

Configuration

Install the plugin: Manage Jenkins → Plugins → Prometheus Metrics Plugin

After installation, metrics are available at <jenkins-url>/prometheus.

Option A — Prometheus scrape

scrape_configs:
  - job_name: jenkins
    metrics_path: /prometheus
    static_configs:
      - targets: ['localhost:8080']

remote_write:
  - url: https://<region>.xscalerlabs.com/api/v1/push
    headers:
      X-Scope-OrgID: <tenant-id>
    basic_auth:
      password: <api-token>

Option B — Grafana Alloy

prometheus.scrape "jenkins" {
  targets      = [{"__address__" = "localhost:8080"}]
  metrics_path = "/prometheus"
  forward_to   = [prometheus.remote_write.xscaler.receiver]
}

prometheus.remote_write "xscaler" {
  endpoint {
    url = "https://<region>.xscalerlabs.com/api/v1/push"
    headers = { "X-Scope-OrgID" = "<tenant-id>" }
    basic_auth { password = "<api-token>" }
  }
}

Option C — OpenTelemetry Collector

receivers:
  prometheus:
    config:
      scrape_configs:
        - job_name: jenkins
          metrics_path: /prometheus
          static_configs:
            - targets: ['localhost:8080']

exporters:
  prometheusremotewrite:
    endpoint: https://<region>.xscalerlabs.com/api/v1/push
    headers:
      Authorization: Bearer <api-token>
      X-Scope-OrgID: <tenant-id>

service:
  pipelines:
    metrics:
      receivers: [prometheus]
      exporters: [prometheusremotewrite]

Logs

Collect Jenkins server log including build output and system events. Add the following to your Alloy config:

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

loki.source.file "jenkins_logs" {
  targets    = local.file_match.jenkins_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") }
  }
}
