# Integration Broker > Integration Broker alerts: operation errors, contract errors, stalled messages, abnormal volume detection, and sync exceptions. --- Site [llms.txt](/llms.txt) --- Integration Broker alerts monitor your PeopleSoft IB infrastructure for errors, stalled messages, volume anomalies, and sync exceptions. **Where to start.** For a new environment, enable IB Down, IB Dispatcher Down, IB No Active Domain, and IB Operation Errors first. These four catch the conditions that produce the most pages. Add stalled checks after tuning thresholds for your operations. Volume checks need 24 hours of history before they fire usefully. | Alert | Description | | ----------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------ | | [IB Operation Errors](/docs/alerts/integration-broker/ib-operation-errors/) | Async IB operation instances in Error or Timeout status | | [IB Publication Contract Errors](/docs/alerts/integration-broker/ib-pub-contract-errors/) | IB publication contracts in Error or Timeout status | | [IB Subscription Contract Errors](/docs/alerts/integration-broker/ib-sub-contract-errors/) | IB subscription contracts in Error or Timeout status | | [IB Operations Stalled](/docs/alerts/integration-broker/ib-operation-stalled/) | Async IB operations stuck in New or Working status longer than the threshold | | [IB Publication Contracts Stalled](/docs/alerts/integration-broker/ib-pub-contract-stalled/) | IB publication contracts stuck in New or Working status | | [IB Subscription Contracts Stalled](/docs/alerts/integration-broker/ib-sub-contract-stalled/) | IB subscription contracts stuck in New or Working status | | [Abnormal IB Operation Volume](/docs/alerts/integration-broker/ib-operation-volume/) | IB operation instance volume exceeds the rolling historical average by the configured percentage | | [Abnormal IB Publication Contract Volume](/docs/alerts/integration-broker/ib-pub-contract-volume/) | Publication contract volume exceeds the rolling historical average by the configured percentage | | [Abnormal IB Subscription Contract Volume](/docs/alerts/integration-broker/ib-sub-contract-volume/) | Subscription contract volume exceeds the rolling historical average by the configured percentage | | [IB Sync Operation Exceptions](/docs/alerts/integration-broker/ib-sync-exceptions/) | Synchronous service operations with errors in the sync transaction log (PSIBLOGHDR) | | [Integration Broker Down](/docs/alerts/integration-broker/ib-down/) | SWS connection failure indicating Integration Broker is down | | [IB No Active Domain](/docs/alerts/integration-broker/ib-no-active-domain/) | Detects when no active message domains exist in PSAPMSGDOMSTAT | | [IB Dispatcher Down](/docs/alerts/integration-broker/ib-dispatcher-down/) | Active domain dispatcher processes that are inactive or stalled | | [IB Nodes Down](/docs/alerts/integration-broker/ib-nodes-down/) | Message nodes registered as down in PSNODESDOWN with blocked transactions | --- Section pages: -
