Requires an API key with the write scope or higher. Update an existing LastPing monitor's schedule/config by UUID using merge-patch semantics: only the fields you supply are changed, and any field you omit keeps its current stored value. If supplied, tags replaces the full tag set on the monitor (not merged). slug is immutable and cannot be changed. This is also the tool that sets a monitor's OUTPUT ASSERTIONS (the assertions argument) — conditions the ping body of a successful run must satisfy, which is how a job that exits zero having done nothing gets caught — and its METRIC GUARDS (the guards argument) — ceilings on a number the job reports, which is how an agent that loops and burns money gets caught. Like tags, assertions and guards each REPLACE the full set. ci_provider is NOT patchable — it is immutable once set, so only its ci_workflow/ci_branch filters can be changed here; rebinding a monitor to a different CI system means deleting and recreating it.
