Diagnostics CLI (nrdiag) v3.9.0

Task Updates

• K8s/AgentControl/Logs - Updated to collect all log lines (#267).

New Feature

• We have added a new suite and the following tasks for Agent Control (#268):
  • onhost-agent-control suite - Gathers information about agent-control logs, status, connectivity, and resources on the host. To use it, run nrdiag -suites onhost-agent-control.
  • AgentControl/Config/Agent - Detects agent-control via PATH, known install paths, and data directory fallback; collects all YAML files from fleet-data and local-data, preserving the original directory structure for all registered sub-agents
  • AgentControl/Config/DirTree - Writes a formatted directory tree of all agent-control installation paths to the zip for structure inspection
  • AgentControl/Agent/Connect - Checks TCP/TLS reachability of the OpAMP, JWKS, and OAuth2 token endpoints (reading URLs from local_config.yaml); validates that the local identity private key is a readable, parseable PKCS8 key (RSA, Ed25519, or ECDSA)
  • AgentControl/Agent/Logs - On Linux, collects logs via journalctl -u newrelic-agent-control; on Windows, globs all date-rotated *.newrelic-agent-control.log files from the default log directory
  • AgentControl/Agent/StatusServer - Queries the local status server at the host/port configured in local_config.yaml (default 127.0.0.1:51200) and saves the JSON response to the diagnostics zip
