The core vocabulary used throughout Minion Agent's help topics -- what each one is, and why it exists, in one place.
Availability Group (AG)
SQL Server's own high-availability feature: a set of databases replicated across several servers (replicas), with exactly one holding the Primary role (live, read-write) at a time and the rest Secondary (standby copies). SQL Server can fail over between them, planned or not. See Availability Group Settings for how a job or step stays correct through a failover.
Constant
A named value referenced in step command text (MAconst:Name) instead of being retyped everywhere it's needed -- change it once, every step referencing it picks up the new value on its next run. See Constants.
Credential
A stored, encrypted set of connection details (a SQL login or Windows account) a step uses to actually connect to a Target Server. Scoped per Target Server -- a credential is only ever valid against the server(s) it was set up for.
Gate
A named, reusable pause/stop condition -- a CPU/memory/runtime threshold, a file to wait for, or another job's status -- attached to a job or step. Not the same thing as Availability Group Settings' own skip-gate, despite the shared name: that one only ever checks one specific database's current AG role, nothing else. See Gates.
Job Trigger
Chains jobs by outcome -- when one job reaches a chosen status, a trigger starts a different job automatically. See Job Triggers.
Permission
What a Role grants -- a specific action (Run, Edit, Manage, and so on) against a specific scope (Everywhere, a folder, a job, a Target Server). See Roles, Permissions, and Identity.
Schedule
A recurring day/time pattern that starts a job on its own, without anyone clicking Run. See Schedules.
Sync Peer
Another Minion Agent installation this one can reach over its own Api, for Fleet Job Sync. See Fleet Job Sync.
Target Server
Any SQL Server instance registered in Minion Agent that a job or step is allowed to run against -- nothing can be targeted unless it's listed here first, a deliberate security boundary, not just an inventory. See Target Servers.
