Module metrics 

The dashboard’s and the health alerts’ counts over the whole ledger.

Structs

CreditRegistrationErrorCodeCount

Live rows carrying an error code, split by whether the pipeline is still working on them.

CreditRegistrationThroughputDay

One day of terminal outcomes, for the throughput series.

ModuleRegistrationTotals

Live volumes per course module, for the Courses tab’s one row per module.

OldestNonTerminalRegistration

The row that has been waiting longest for the pipeline to do something with it.

RegistrationLatency

How long registration took, in seconds, for rows that reached registered in a window.

StuckRegistrationCount

StuckThresholds

How long a row may sit in one state before it counts as stuck. Seconds, per state.

TerminalOutcomeTotals

What the pipeline finished in a window.

Functions

count_by_error_code

The error-code breakdown the Overview shows.

count_by_module

failed_count is failed_permanent and misregistered only, so the columns do not add up to the total by design.

count_by_state

Live rows per state, for the dashboard funnel. Superseded attempts are excluded, as in the per-course sibling, or a course that regrades counts every student twice.

count_due_enrolment_checks

Live rows parked in no_usable_enrolment that an unscoped resolve-enrolments claim would take for an enrolment check now; the rest wait for their schedule, their module, or a lookup already out. Leaves out the claim’s one-row-per-student-and-module hold, which only defers a row.

count_entered_state_since

Live rows that entered one state within the window. misregistered is not terminal, so terminal_at cannot answer this.

count_pending_by_reason

Live pending rows per blocker. Derived from credit_registration_preconditions, so it cannot disagree with what the recompute is waiting for or with what the student is shown.

count_stuck

Rows the pipeline should have moved by now, per state. Only the four states with a threshold count: the rest wait on a student or a human, where an alert would fire on normal operation.

count_terminal_outcomes_since

get_oldest_non_terminal

get_registration_latency_between

get_throughput_by_day

Daily terminal outcomes over the window. Withdrawn rows are in no column: they are neither a success nor a failure.
