System Center Monitoring Pack for System Center 2012 — App Controller: Complete GuideThis guide explains what the System Center Monitoring Pack for System Center 2012 — App Controller is, why it matters, how it works, how to install and configure it, common troubleshooting steps, and best practices for effective monitoring. It’s aimed at systems administrators and monitoring engineers using System Center 2012 who need to monitor App Controller health and functionality across private and public cloud resources.
What is the Monitoring Pack for App Controller?
System Center Monitoring Pack for System Center 2012 — App Controller is a set of management pack components designed to extend System Center Operations Manager (SCOM) so it can monitor Microsoft System Center 2012 App Controller. The pack provides discovery rules, monitors, alerts, performance counters, and knowledge articles specific to App Controller roles and services. It lets administrators proactively detect issues, track performance trends, and correlate App Controller availability and health with other System Center components.
Key monitoring coverage typically includes:
- App Controller service availability and responsiveness
- App Controller web application and IIS health
- Communication between App Controller and other System Center components (e.g., VMM and Configuration Manager)
- Authentication and certificate problems
- Performance metrics for request throughput, memory, CPU, and thread usage
- Event and log-based alerts for known failure conditions
Why monitor App Controller?
App Controller is a bridging component that enables administrators and tenants to manage cloud services and virtual machines across private clouds (System Center Virtual Machine Manager) and public clouds (Windows Azure / Azure). A malfunctioning App Controller can block self-service operations, hamper service deployment, and mask larger integration issues. Monitoring helps you:
- Maintain service availability and responsiveness for users
- Detect integration problems with VMM, library servers, or cloud providers
- Track performance trends to plan capacity and scaling
- Automate alerting and remediation workflows to reduce downtime
Prerequisites and compatibility
Before installing the monitoring pack:
- Ensure you have a supported environment: System Center 2012 Operations Manager and App Controller 2012 (and relevant Update Rollups). Confirm exact versions and update rollups in your environment match the monitoring pack’s requirements.
- SCOM management servers and console must be accessible and properly configured.
- SCOM agents must be installed on App Controller servers or use agentless monitoring where supported.
- Appropriate administrative permissions in SCOM and on target servers.
- Network connectivity between SCOM servers, management servers, App Controller, VMM, and other System Center components.
Components of the monitoring pack
Typical elements included in the MP:
- Discovery rules and classes to detect App Controller roles and instances
- Monitors targeting service state, IIS application pools, and application responsiveness
- Performance collection rules for CPU, memory, requests/sec, active connections, thread counts
- Event-based rules to convert key Windows Event Log entries into SCOM alerts
- Views, dashboards, and reports for App Controller health and performance
- Knowledge articles and recommended remediation steps embedded in alerts
- Overrides and tuning snippets to adjust thresholds per environment
Installation steps
-
Obtain the monitoring pack
- Download the official System Center Monitoring Pack for App Controller from Microsoft or from your internal repository. Verify the version matches App Controller and SCOM Update Rollups.
-
Import the management pack into SCOM
- Open the SCOM Operations console.
- Go to Administration → Management Packs → Import Management Packs.
- Browse and select the MP file(s) (.mp or bundled .mpb).
- Review dependencies and import any required base packs first (e.g., Microsoft.Platform.Health, Windows Server OS MPs, IIS MP).
-
Configure Run As accounts and profiles
- App Controller monitoring may require specific Run As accounts to query APIs, WMI, or access performance counters. Create and distribute Run As accounts with least privilege, and map them to the MP’s Run As profiles.
-
Deploy agents (if needed)
- Ensure SCOM agents are installed on App Controller servers. Use SCOM agent deployment or manual installation. Verify agent health.
-
Tune discoveries and overrides
- Allow time for discoveries to run. Validate that App Controller objects appear in the SCOM monitoring tree.
- Apply overrides for monitor thresholds or disable noisy monitors initially to avoid alert storms.
-
Validate monitoring
- Trigger known conditions (e.g., stop a service or recycle an App Pool) to confirm monitors generate expected alerts.
- Review performance collection and dashboards for expected metrics.
Configuration and tuning
- Override thresholds: Default thresholds often need tuning to match your environment. Use the SCOM console to create management pack–scoped overrides targeted at specific App Controller instances or groups.
- Create groups: Group App Controller servers by role, location, or tenant to apply targeted monitoring and overrides.
- Alert suppression and escalation: Configure suppression windows for planned maintenance and configure alert subscriptions for correct on-call teams.
- Performance retention: Adjust SCOM data warehouse and reporting settings if you need long-term retention of App Controller performance counters.
- Maintenance mode: Use maintenance mode for App Controller updates, patches, or planned changes to prevent false alerts.
Common alerts and how to respond
- App Controller service stopped or not responding
- Check Windows service status, IIS app pool, and event logs. Restart service or recycle app pool if safe; check for underlying errors.
- Authentication failures or certificate errors
- Verify certificates used by App Controller and its trust chain. Confirm credentials used for Run As accounts have not expired.
- Communication errors with VMM or other SC components
- Check network connectivity, firewall rules, service endpoints, and integration service accounts.
- High CPU/memory or thread count
- Review recent activity (deployments, imports). Consider scaling App Controller roles or optimizing workloads. Collect memory dumps if needed.
- Excessive request latency or failed HTTP requests
- Check IIS logs, application errors, and backend dependencies. Investigate load balancer and SSL/TLS negotiation issues.
Troubleshooting steps
- Check SCOM generated alert details and associated knowledge.
- Review Windows Event Logs on App Controller servers for correlating errors.
- Examine IIS logs and application diagnostics to identify request failures.
- Validate service accounts, certificates, and integration endpoints (VMM, library servers).
- Use SCOM Health Explorer to drill into monitor health and component-level details.
- Enable verbose logging temporarily on App Controller if needed and collect logs for analysis.
- If the monitoring pack itself misdiscovers or fails, check MP dependencies, Run As configuration, and ensure agent health.
Best practices
- Keep SCOM and App Controller updated with supported update rollups and service packs.
- Test the monitoring pack in a lab or staging environment before production rollout.
- Apply overrides gradually and scope them narrowly (by server or group) rather than globally.
- Use Run As accounts with least privilege and rotate credentials regularly.
- Automate common remediations (service restart scripts, runbooks) and integrate with System Center Orchestrator or other automation tools.
- Monitor the monitoring system: ensure SCOM’s own health is tracked, including data collector and data warehouse performance.
- Maintain documentation of overrides and changes to management packs for auditing and future troubleshooting.
Reporting and capacity planning
Use SCOM reporting and performance views to:
- Track request volumes and latency trends for App Controller
- Forecast resource needs (CPU/memory) and plan scaling
- Identify usage patterns that correlate with tenant activity or deployments
- Retain historical data in the data warehouse for compliance or trend analysis
When to customize or extend the pack
Customize when:
- You have custom App Controller integrations or plugins not covered by the default MP.
- You need tenant-specific or role-specific monitors.
- You want finer-grained performance thresholds or custom reports.
Extend by:
- Creating new monitors/rules targeted at custom events or application logs.
- Adding additional performance counters or synthetic transactions.
- Integrating SCOM alerts with ticketing or automation platforms.
