Mastering UCM Exporter: The Complete Step-by-Step Integration Guide
Monitoring Cisco Unified Communications Manager (CUCM) is critical for maintaining enterprise voice and video network health. The UCM Exporter bridges the gap between Cisco’s complex management layer and modern observability tools like Prometheus and Grafana. This comprehensive guide walks you through the entire integration process, turning raw telephony metrics into actionable dashboard insights. Understanding UCM Exporter
The UCM Exporter is a specialized monitoring tool designed to extract performance metrics from Cisco Unified Communications Manager cluster environments. It translates Cisco-specific data formats into standard Prometheus metrics. Why Use UCM Exporter?
Centralized Observability: Eliminates data silos by bringing voice network metrics into your standard DevOps monitoring stack.
Proactive Alerting: Enables instant notifications for dropped calls, registration failures, and trunk capacity issues.
Historical Trend Analysis: Replaces short-lived Cisco RTMT data with long-term retention capabilities in Prometheus. Key Metrics Tracked
Media Resources: Transcoder, conference bridge, and MTP utilization.
Device Registrations: Real-time counts of registered, unregistered, and rejected IP phones.
Trunk Performance: Active call volumes and error rates across SIP and H.323 trunks.
System Health: CPU utilization, memory allocations, and disk partition usage per CUCM node. Step 1: Preparing the CUCM Environment
Before installing the exporter, you must configure CUCM to allow programmatic read access to performance data. 1. Enable AXI and PerfMon Services
Navigate to Cisco Unified Serviceability and ensure the following services are active: Cisco AXL Web Service Cisco RIS Data Collector Cisco AMC Service 2. Create a Dedicated Application User
Go to Cisco Unified CM Administration > User Management > Application User. Click Add New.
Create a username (e.g., ucm_exporter_user) and a secure password. Assign the following roles to the user group: Standard AXL API Access Standard SERVICEABILITY Read Only Step 2: Installing and Configuring UCM Exporter
The exporter runs as a standalone binary or Docker container within your monitoring infrastructure network. Option A: Running via Docker (Recommended)
Create a docker-compose.yml file to spin up the container quickly:
version: ‘3.8’ services: ucm-exporter: image: profile/ucm-exporter:latest container_name: ucm_exporter ports: - “9110:9110” environment: - UCM_HOST=10.1.10.5 - UCM_USER=ucm_exporter_user - UCM_PASSWORD=YourSecurePassword Here restart: unless-stopped Use code with caution. Option B: Configuration File Setup
If running the native binary, define your targets in a config.yml file:
ucm: hosts: - 10.1.10.5 - 10.1.10.6 username: “ucm_exporter_user” password: “YourSecurePasswordHere” timeout: 10s server: listen_address: “:9110” Use code with caution.
Run the binary passing the config flag: ./ucm_exporter –config.file=config.yml Step 3: Integrating with Prometheus
With the exporter exposing metrics on port 9110, configure your Prometheus server to scrape this endpoint. Update prometheus.yml Add a new job entry to your scrape configuration file:
scrape_configs: - job_name: ‘ucm-exporter’ scrape_interval: 30s static_configs: - targets: [‘localhost:9110’] labels: environment: ‘production’ cluster: ‘hq-cucm-cluster’ Use code with caution. Verify the Targets Restart or reload your Prometheus service. Navigate to your Prometheus web UI (http://localhost:9090). Go to Status > Targets. Confirm that the ucm-exporter job status shows as UP. Step 4: Visualizing Data in Grafana
Raw metrics become truly valuable when visualized. Import or build a dashboard to monitor your unified communications ecosystem. Connecting the Data Source Log into your Grafana instance. Navigate to Connections > Data Sources.
Select Prometheus and enter your server URL (http://localhost:9090). Click Save & test. Creating Critical Panels
Use these exact PromQL queries to build your baseline dashboard visual panels: Active Calls Panel:sum(ccmActiveCalls{status=“active”})
Unregistered Phone Alerts:ccmPhoneStatus{status=“unregistered”} > 0
Gateway Trunk Utilization:ccmTrunkChannelsActive / ccmTrunkChannelsAvailable100 Step 5: Setting Up Alerting Rules
Don’t wait for users to report dropped calls. Implement these production-ready Prometheus alerts to get ahead of issues. Create a file named ucm_alerts.yml:
groups: - name: ucm_performance_alerts rules: - alert: HighUnregisteredPhones expr: sum(ccmPhoneStatus{status=“unregistered”}) > 50 for: 5m labels: severity: critical annotations: summary: “Mass IP phone unregistration detected” description: “Over 50 phones have dropped off the network in the last 5 minutes.” - alert: TrunkCapacityReached expr: (ccmTrunkChannelsActive / ccmTrunkChannelsAvailable) > 0.90 for: 3m labels: severity: warning annotations: summary: “SIP Trunk saturation high” description: “Trunk capacity is exceeding 90% utilization limit.” Use code with caution.
Link this file under the rule_files block in your main prometheus.yml configuration. Troubleshooting Common Integration Issues Exporter Returns HTTP 401 Unauthorized
Cause: Incorrect application user credentials or missing AXL permissions.
Fix: Double-check the user profile in CUCM. Test the AXL connection manually using a tool like Postman before running the exporter. Context Deadline Exceeded / Timeouts
Cause: Network firewalls or slow responding RIS Data Collector services on CUCM.
Fix: Verify network access on TCP ports 8443 (AXL) and 5000 (RIS). Increase the timeout parameter in your exporter config file to 30s. Metric Values Are Missing or Empty
Cause: The specific services are deactivated on the targeted CUCM subscriber nodes.
Fix: Ensure the Cisco AMC Service is running on all nodes across the cluster, not just the publisher. To help refine this setup for your network, let me know: What version of CUCM are you currently running?
Which alerting platform do you plan to connect (PagerDuty, Slack, Email)?
