Important Notes for Upgrade

Pre- and post-upgrade tasks should be reviewed and completed as needed to ensure a successful upgrade.
Some releases within the upgrade path (Zurich and Australia) had no updates or changes.
Highlights from Zurich include the ability to discover TLS/SSL certificates, improved resource management by disabling only intensive checks, enhanced troubleshooting via instance error views, and macOS file-based Discovery support.

By understanding these enhancements and upgrade considerations, ServiceNow customers can optimize ACC functionality for better performance, security, and visibility across their environment from Zurich through to Australia releases.

Release	Release notes
Zurich	Agent Client Collector Framework Upgrade MID-less agents Starting in version 6.0.0, perform selective and high-volume upgrades on ACC agents when not using a MID Server by using products such as DEX and ACC-VC. [Placeholder link text to key verify-agent-functionality] Starting in version 6.0.0, verify that an agent is functioning properly by performing a self-test on the agent. [Placeholder link text to key acc-workspace-dashboard] Starting in version 6.0.0, view a list of agents and their statuses on the ACC Workspace dashboard. Use improved debug logging Starting in version 6.0.0, benefit from enhanced debug logging by sending all debug statements to a log file Manage Agent Client Collector certificates Starting in version 5.0, configure a schedule by which to rotate Agent Client Collector certificates which enable communication between agents and ITOM Cloud Services. Rotating certificates ensures that when a certificate expires, a new certificate is in place. Perform high-volume Agent Client Collector upgrade in a macOS environment Starting in version 5.0, upgrade large numbers of Agent Client Collector agents at a time that are running on macOS. This extends the existing high-volume upgrade capabilities available for Windows and Linux in the 4.3.0 release. Use an IMDSv2 endpoint for metadata discovery Starting in version 5.0, the IMDSv2 endpoint for metadata discovery is invoked when using Agent Client Collector in an AWS EC2 environment. Use enhanced errors and diagnostics to troubleshoot issues with servers and endpoints Starting in version 5.0, view errors that occur before or after the registration process when Agent Client Collector connects to the instance. This provides enhanced debugging capabilities by enabling you to view issues in the instance, without requiring direct access to the agent logs. Disable checks using heavy system resources while in CPU protection mode Starting in version 5.0, disable only those checks that are causing high CPU usage while in CPU protection mode. It is still possible to disable all checks and completely stop data collection while in CPU protection mode. In a Windows environment, Agent Client Collector has improved the accuracy of how check CPU usage is monitored. Configuration data files size limit Starting in version 5.0, configuration data files have a maximum size of 10MB. Configure Agent Client Collector with proxy auto-configuration (PAC) files Starting in version 5.0, enable easier connection of Agent Client Collector to a proxy server by using a proxy auto-configuration (PAC) file. Agent Client Collector Monitoring [Placeholder link text to key gcp-config-file] Starting in version 3.15.0, GCP checks provide added support to configure metrics through a configuration file in JSON format. Monitor Linux events Starting in version 3.15.0, monitor Linux events using Linux event checks. Agent Client Collector for Visibility Content Discover MSSQL components using ACC-VC Starting in version 1.5.0, use ACC-VC to discover MSSQL components in your environment. Discover software information with ACC-VC using SWID tags Starting in version 1.5.0, gather software information with ACC-VC using software identification (SWID) tags on an agent and a ServiceNow® instance. Run certificate Discovery using Agent Client Collector for Visibility Content Starting in version 1.3.0, use the Agent Client Collector for Visibility Content to discover TLS/SSL certificates used by the ports running on the server's configuration items (CIs). Certificate Inventory and Management uses the certificate data to manage the TLS/SSL certificate life cycle. File-based Discovery is supported in a macOS environment Starting in version 1.3.0, use File-based Discovery in a macOS environment. Collect metrics using non-osqueryd data collection Starting in version 1.3.0, collect data more efficiently by invoking non-osqueryd data collection.
