Description of the Solution

This PR expands LDMS deployment and cleanup orchestration, improves telemetry status reporting, and adds comprehensive LDMS and OME validation. It also centralizes reusable credential, inventory, command, and validation utilities in omnia_auto.

Changes

LDMS Deployment

  • Added sampler deployment for architecture-specific Slurm control, compute, login, and login-compiler groups
  • Added per-node sampler configuration and systemd service management
  • Added firewall, service-state, and listening-port verification
  • Propagated slurm_cluster_mount to sampler nodes
  • Expanded the LDMS host map with Control, Compute, Login, and LoginCompiler subroles
  • Added Kafka producer association to the LDMS storage policy
  • Corrected the sampler service name to ldmsd.service

Cleanup and Status Reporting

  • Added delegated LDMS sampler cleanup tasks
  • Added source-before-sink ordering during full telemetry cleanup
  • Added component cleanup result tracking
  • Added write_cleanup_status.yml
  • Unified deployment and cleanup status generation through telemetry_status.yml.j2
  • Added deploy and cleanup status types
  • Added component states including deployed, cleaned, failed, and skipped

LDMS Validation

  • Added LDMS package-installation validation
  • Added sampler service and plugin-configuration validation
  • Added earliest and latest Kafka-data validation
  • Added per-host and per-plugin metric reporting
  • Added human-readable Kafka timestamps
  • Centralized LDMS constants, paths, messages, and commands in ldms_vars.py
  • Added reusable LDMS validation functions in ldms_func.py

OME Validation

  • Added external Kafka certificate validation
  • Added PFX certificate generation
  • Added OME server and client certificate upload
  • Added uploaded-certificate comparison
  • Added Kafka forwarder configuration and connectivity validation
  • Added validation for OME telemetry, inventory, alerts, health, and audit-log topics
  • Centralized OME constants and commands in ome_vars.py

Shared Test Automation

  • Added generic encrypted credential-field prompting
  • Added reusable inventory host and host-variable lookup functions
  • Updated validation-runner behavior and help output
  • Updated telemetry and image-build setup scripts
  • Rebuilt the omnia_auto wheel
  • Removed tracked test_creds.yml

…lemetry_config

- Remove kube_vip from telemetry_config.json schema required fields
- Update validation to extract kube_vip from cluster_inventory file
  (kube_vip_group.hosts[0].ansible_host or hostname)
- Remove directory restriction for cluster_inventory path (can be absolute)
- Update error messages to reflect kube_vip comes from cluster_inventory
- Remove unused KUBE_VIP_REQUIRED_MSG

Migrate external_kafka_connect_details from omnia_core (2.2) to the
monorepo telemetry domain (2.3) following the new architecture.

Changes:
- Add external_kafka_connect role under roles/
  - Validates Kafka pods health on kube_vip
  - Extracts bridge LB external IP and TLS certs from K8s secrets
  - Writes ca.crt, user.crt, user.key, and connection details YAML
  - Displays OME mTLS integration steps
- Add playbook at playbooks/utils/external_kafka_connect.yml
  - Reuses telemetry_prereq.yml for config loading and kube_vip resolution
  - No dependency on high_availability_config.yml (uses cluster_inventory)
- Register as --tags external_kafka in telemetry.yml
- Add external_kafka to usage help in telemetry_setup vars
- Output generated at: /opt/omnia/telemetry/output/project_default/external_kafka/

…Helm deploy

- Fix cleanup tag isolation: import_playbook tags were inherited by
  parent, causing all components to be cleaned when only one tag was
  specified (e.g. cleanup_powerscale deleted Kafka, Victoria, OME).
  Restructured cleanup.yml to use include_tasks with ansible_run_tags
  conditions instead of import_playbook with tags.

- Add karavi-observability Helm deployment: the old container staged
  files to NFS and deferred helm install to cloud-init. Now the
  deploy_powerscale role directly runs helm install/upgrade for
  karavi-observability, applies cert-manager CRDs, copies isilon-creds
  secret, patches OTEL collector service for Prometheus metrics, and
  creates OTEL collector PVC for persistent buffering. This adds the
  previously missing pods: karavi-metrics-powerscale, otel-collector,
  cert-manager (3 pods).

- Add csi_powerscale_secret_path input validation.

- Clean up external_kafka_connect output to show only file location
  and bootstrap IPs/ports.

- Add csi-volume-exporter resources to cleanup vars (deployment,
  service, serviceaccount, clusterrole, clusterrolebinding).

…empotency

- Fix key-order[task] in all 7 cleanup _tasks.yml files (name: before module)
- Add Dell copyright headers to all cleanup task include files
- Add source-before-sink guard in cleanup.yml: check remaining source pods
  and wait for termination before proceeding to sink cleanup
- Fix risky-shell-pipe: add set -o pipefail to all shell tasks with pipes
- Fix yaml[line-length]: break lines exceeding 160 chars
- Fix jinja[spacing]: correct Jinja2 whitespace in folded scalars
- Add csi_powerscale_secret_path to telemetry_config.json schema validation
- Improve pod stabilization wait in deploy.yml with explicit Ready check
- Ensure telemetry_status.yml is idempotent (gather_facts: true on Phase 5)
- Refactor telemetry_packages.yml schema and validation for new package
  manifest format (Helm charts, git repos, pip modules)
- Add OME source to telemetry_status.yml.j2 template and write task
- Cleanup summary shows explicit remaining pod/PVC/service counts
- All files pass ansible-lint 26.8.0 (profile: production, 0 failures, 0 warnings)

Verified: full cleanup (0 pods/PVCs/services) + deploy (40/40 pods Ready)

Consolidate 11 separate cleanup_* roles into a single roles/cleanup
role with per-component task files. This eliminates code duplication
across cleanup playbooks and centralizes cleanup variables.

Changes:
- Create roles/cleanup/ with task files for each component
  (idrac, ldms, ome, powerscale, ufm, vast, dcgm, sfm,
  kafka, victoria_metrics, victoria_logs)
- Refactor cleanup.yml to use include_role with tasks_from
  instead of include_tasks from separate _tasks.yml files
- Update standalone cleanup playbooks to use the consolidated role
- Add missing cleanup tags for ufm, vast, dcgm, sfm sources
- Fix UFM/VAST resource names to match deployed service names
  (ufm-external, vast-external)
- Improve deploy templates for UFM, VAST, OME, PowerScale
- Add credential exposure as top-level facts in telemetry_prereq
- Update deploy.yml phase comments to reflect actual flow

Tested: full cleanup + deploy cycle passes (40/40 pods ready)

Major redesign of telemetry FVT test framework:

Test structure:
- Flatten test hierarchy: remove per-source/sink subdirectories
  (e.g. sinks/kafka/test_kafka.py -> sinks/test_kafka.py)
- Remove duplicate fvt/telemetry/ folder; consolidate into tag-based folders
- Add cleanup/ tag folder with test_playbook.py and verify_cleanup tests
- Rename test_vm.py -> test_victoriametrics.py, test_vl.py -> test_victorialogs.py

New test sources:
- PowerScale: CSM deploy, OTEL collector, isilon-creds secret, VM metrics,
  VL logs, syslog forwarding (TC_SR_008 - TC_SR_013)
- UFM: external service, VMServiceScrape, credentials secret, InfiniBand
  metrics in VictoriaMetrics (TC_SR_016 - TC_SR_019)
- OME: Vector bridge, KafkaUser CR, Kafka cert upload and connectivity
  (TC_SR_014 - TC_SR_015, TC_SR_021)
- iDRAC: graceful skip when StatefulSet not found (no BMC inventory)

CLI redesign (run_validation.sh):
- Domain name as first argument: ./run_validation.sh telemetry <cmd>
- Rename deploy command to exec for playbook execution
- Tag-based routing: ./run_validation.sh telemetry deploy verify
- OMNIA_DEPLOY_TAG env var for test_playbook.py tag selection

Library:
- Split monolithic source_func.py into powerscale_func.py, ufm_func.py,
  ome_func.py

Bug fix: LDMS sampler was only being deployed on slurm_node (compute
nodes). It should be deployed on ALL LDMS-enabled nodes:
- slurm_node (compute nodes)
- slurm_control_node (control node also runs sampler)
- login_node
- login_compiler_node

Changes:
- Add login_node and login_compiler_node to inventory in pre_tasks
- Add sampler configuration plays for slurm_control_node, login_node,
  and login_compiler_node
- Use max_fail_percentage: 100 to continue on node failures
