- Supply chain layers
- The supply chain is a layered graph where supply entities such as hosts, datastores, clusters, and storage provide resources to demand entities such as VMs, pods, containers, and applications.
- Market analytics engine
- The decision core that computes actions by resolving contention for shared resources among supply chain entities, rather than by comparing metrics to static thresholds.
- Multi-node deployment
- An installation topology where platform services, the database, and analytics run on separate nodes for scale and availability, requiring an external supported database.
- Installation prerequisites
- Before installing, confirm supported OS version, bidirectional DNS resolution, synchronized time via NTP, and required port access between nodes and targets.
- License capacity model
- Licensing is capacity-based per entity type, so the license file defines covered editions and entity types, and usage is measured against licensed capacity for compliance.
- Action mode default
- The platform-wide default action mode, Recommend, Manual, or Automatic, applies where no more specific policy overrides it for the scoped entities.
- Role-based access
- Administrator, scoped site administrator, and read-only roles determine whether a user may execute actions or only view entities, actions, and reports.
- SSO and LDAP mapping
- Directory groups from LDAP/AD or SAML/OIDC single sign-on are mapped to platform roles, so membership changes in the directory change effective permissions.
- Target credential validation
- Each target's credentials are validated against the endpoint; a failed validation blocks discovery and automation for that target until corrected.
- Read vs action credentials
- Monitoring credentials only permit discovery, while automation credentials with higher privileges are required for the platform to execute actions on the target.
- Stitching
- Stitching correlates entities reported by different targets, such as a VM, its datastore, and the backing storage array, so shared resources are modeled once.
- Target groups
- Targets can be organized into groups so that policies and scopes apply to many targets at once instead of being configured individually.
- Policy precedence
- The effective policy is the most specific applicable one: entity-level settings override group-level policies, which override global platform defaults.
- Placement policy
- Placement policies constrain which clusters or hosts a workload may move to, including pinning and anti-affinity, limiting the actions the engine may propose.
- Scaling policy
- Scaling policies define whether a workload may scale and set bounds such as minimum and maximum replicas or VM size limits.
- Scheduling policy
- Scheduling policies define time windows during which automation is permitted or suppressed, letting administrators block changes during business-critical periods.
- Resize action
- A resize action changes an entity's allocated capacity up or down when sustained utilization falls outside the acceptable range set by headroom constraints.
- Move action
- A move action migrates a workload to another host or cluster when the current host is over-utilized and a destination can absorb it without violating policies.
- Benefit versus risk
- The engine ranks candidate actions by expected benefit in utilization or performance against the risk of contention if the action is executed.
- Action approval workflow
- In Manual mode, pending actions are listed for review; approving one causes the platform to execute it on the target using the automation credential.
- Provision action
- A provision action adds capacity, such as a host or node, when existing supply cannot satisfy demand without violating constraints after other actions.
- Action not executing
- When actions do not run, check in order the applicable action mode policy, approval status, credential permissions, and target connectivity.
- Missing entities
- Entities absent from the supply chain usually indicate a target discovery failure, missing stitching, or a target that was removed from the platform.
- Audit and action history
- History records which actions were proposed, approved, and executed, by whom and with what result, and is the primary trace for automation questions.
- Time skew impact
- Clock drift between the platform and targets can cause authentication and discovery failures, so NTP synchronization is a standard troubleshooting check.
- REST API usage
- The REST API exposes entities, actions, and policies for querying and allows actions to be approved or executed programmatically by external automation.
- Webhook notifications
- Webhooks push event and action notifications to external systems such as ticketing or chat tools, enabling workflow outside the platform UI.
- APM integration
- Application performance monitoring integrations supply application-level data so workload performance can be correlated with the underlying infrastructure entities.
- Kubernetes operator
- An operator-based deployment lets the platform run natively on Kubernetes or OpenShift and manage container clusters as targets.
- Upgrade order
- For multi-node environments, back up the database first, upgrade services and analytics in supported order, then re-verify targets and policies.
- Backup and restore
- Backups include the database and configuration; a restore must target the same platform version before any further upgrade is applied.
- Discovery interval
- Discovery runs on a target-specific schedule and can be triggered manually; the first run populates the supply chain and later runs refresh it.
