+The Bull Board is a tool that allows you to check issues with scheduling and internal flow runs issues.

+
+## Queue Overview
+
+We have one main queue called `workerJobs` that handles all job types. Each job has a `jobType` field that tells us what it does:
+
+### Low Priority Jobs
+
+#### RENEW_WEBHOOK
+Renews webhooks for pieces that have webhooks channel with expiration like Google Sheets.
+
+#### EXECUTE_POLLING
+Checks external services for new data at regular intervals.
+
+### Medium Priority Jobs
+
+#### EXECUTE_FLOW
+Runs flows when they're triggered.
+
+#### EXECUTE_WEBHOOK
+Processes incoming webhook requests that start flow runs.
+
+#### DELAYED_FLOW
+Runs flows that were scheduled for later, like paused flows or delayed executions.
+
+### High Priority Jobs
+
+#### EXECUTE_PROPERTY
+Loads dynamic properties for pieces that need them at runtime.
+
+#### EXECUTE_EXTRACT_PIECE_INFORMATION
+Gets information about pieces when they're being installed or set up.
+
+#### EXECUTE_VALIDATION
+Checks that flow settings, inputs, or data are correct before running.
+
+#### EXECUTE_TRIGGER_HOOK
+Runs special logic before or after triggers fire.
+
+
+<Info>
+Failed jobs are not normal and need to be checked right away to find and fix what's causing them. 
+They require immediate investigation as they represent executions that failed for unknown reasons that could indicate system issues.
+</Info>
+
+<Tip>
+Delayed jobs represent either paused flows scheduled for future execution, upcoming polling job iterations, or jobs being retried due to temporary failures. They indicate an internal system error occurred and the job will be retried automatically according to the backoff policy.
