Return basic information about the Redis/RQ environment.

Includes Redis connection status, Redis/RQ versions, discovered queue names, and the number of active workers.

Return selected Redis INFO fields.

Defaults to memory, clients, stats, and keyspace sections: used_memory, maxmemory, maxmemory_policy, evicted_keys, connected_clients, and per-database key counts. Unrecognized section names are ignored and listed in ignored_sections rather than raising an error.

List all discovered RQ queues.

Returns, per queue: job counts by status (queued, started, finished, failed, deferred, scheduled, canceled) and the number of workers currently listening to it.

Return detailed status for a single queue by name.

Includes the same per-status counts as list_queues, the age in seconds of the oldest still-queued job (null if empty), and default_timeout in seconds (reflects this server's own default, since RQ does not persist a per-queue default_timeout to Redis). An unknown queue name is not an error -- RQ queues are lazy/virtual, so it returns the same shape with all counts at 0.

Return full details for a single RQ job by ID, or null if it does not exist.

Includes status, origin queue, function name, redacted/truncated args/kwargs/meta, timeout, ttl, dependency IDs, worker name, and lifecycle timestamps. Does not include the job's result or exception info -- use get_job_result for that.

Return a job's result/exc_info, or null if the job does not exist.

Truncated to max_bytes, with a truncated flag when that happened.

List jobs in a queue filtered by status.

status must be one of: queued, started, finished, failed, deferred, scheduled, canceled. Returns up to limit (max 100) job summaries (id, function name, description, status, enqueued_at, started_at, ended_at) starting at offset, plus the total number of jobs at that status in the queue.

Group a queue's failed jobs by function name + exception type.

Scans up to limit failed jobs (default 200) and returns one entry per (function, exception type) group: count, an example job ID, and first/last failure timestamps.

List scheduled jobs in a queue: id, function name, and scheduled time.

Returns up to limit (max 100) entries starting at offset, plus the total number of scheduled jobs in the queue.

List currently registered RQ workers, optionally filtered by queue.

Returns, per worker: name, state (idle/busy/started/suspended), the queue names it listens to, the ID of the job it's currently processing (if any), last heartbeat and its age in seconds, and its successful/failed job counters. If queue is given, only workers listening to that queue are returned.

Return full details for a single worker by name, or null if not currently registered.

Includes state, hostname, IP address, PID, queue names, current job ID (if any), birth/last-heartbeat timestamps (plus heartbeat age in seconds), job counters, and total working time in seconds.

Run read-only diagnostics across queues, workers, and Redis itself.

Returns {"ok": bool, "findings": [...]}; findings is empty and ok is true when nothing is wrong. Each finding has a severity, a stable code (QUEUE_NO_WORKERS, WORKER_STALE_HEARTBEAT, ORPHANED_STARTED_JOB, OLDEST_JOB_TOO_OLD, REDIS_EVICTION_RISK, HIGH_FAILURE_COUNT), a human-readable message, and structured details.
