To monitor the overall health of all replication sets, see [IDR Monitoring dashboard](https://www.servicenow.com/docs/UaD5juasqZXd6C3M29RzLg "Monitor the status of active producer and consumer replication sets, scheduled jobs, seeding requests, license usage, or scheduled replication through the Instance Data Replication (IDR) Monitoring Dashboard.").{#common-issues-idr__table_dsk_121_mkb__entry__2} | Check | Description | |-|-| | Monitor || | [Check connectivity](https://www.servicenow.com/docs/r9kxDGCGnt3RUXRd8UrVrA "Verify the status of services and the connection between your instance and the Instance Data Replication (IDR) message queue.") | Test your IDR instance connectivity to determine the connectivity of your instance to the message queue. | | [Check IDR monitoring dashboard to see if replication jobs are active](https://www.servicenow.com/docs/UaD5juasqZXd6C3M29RzLg "Monitor the status of active producer and consumer replication sets, scheduled jobs, seeding requests, license usage, or scheduled replication through the Instance Data Replication (IDR) Monitoring Dashboard.") | For the dashboard to properly display replication set information, these IDR scheduled jobs must be available and running on your instance: * Hermes Metrics Collection * Hermes Periodic Purge * Hermes Topics Util * IDRConsumerJob * IDRDeltaConsumerJob-\ * IDRHeartbeatJob * IDRMetadataConsumerJob * IDRProducerJob * IDRSeedingProducerJob {#common-issues-idr__ul_vhc_3jl_vkb} If any of these jobs are missing or not running, contact Customer Service and Support. Note: The system only creates the IDRDeltaConsumerJob-\ when a consumer instance subscribes to a producer instance that is outside the local datacenter. | | Producer replication set || | Check activation of the producer replication set | If the status of your producer replication set is In Draft, click Activate. | | Check consumer subscription approval | Review the consumer access requests for your producer replication sets. A consumer replication set must request access before it can receive replication data. | | [Check producer replication log errors](https://www.servicenow.com/docs/wHHXLzuyDDVlkdJr~8AKMw "Identify Instance Data Replication (IDR) errors by viewing the metadata for messages between producer and consumer instances, payload error logs, and message logs.") | Identify IDR errors by viewing the metadata for messages between producer and consumer instances, payload error logs, and message logs. | | Consumer replication set || | Check activation status of the consumer replication set | If the status of your consumer replication set is In Draft, click Activate. | | [Check if you need to synchronize replication sets](https://www.servicenow.com/docs/Qj_CEPgzd029S3VOVA~abQ "Review the status field to check if synchronization is working correctly on the Instance Data Replication (IDR) consumer instance.") | A synchronization issue occurs when a producer instance doesn't send data or a consumer instance doesn't receive data. Synchronization errors appear in the Status field on the consumer instance as Replication Error. | | [Check your consumer replication set status](https://www.servicenow.com/docs/nNcd8P80dSZsEZ8XEkVFMA "Review the status of your consumer replication set and research error messages to identify or fix Instance Data Replication (IDR) replication issues.") | Review the status of your consumer replication set and what that means for your replication. | | Error and status messages || | [Check replication or replication metadata log errors](https://www.servicenow.com/docs/wHHXLzuyDDVlkdJr~8AKMw "Identify Instance Data Replication (IDR) errors by viewing the metadata for messages between producer and consumer instances, payload error logs, and message logs.") | Identify IDR errors by viewing the metadata for messages between producer and consumer instances, payload error logs, and message logs. | | [Check status messages](https://www.servicenow.com/docs/nNcd8P80dSZsEZ8XEkVFMA "Review the status of your consumer replication set and research error messages to identify or fix Instance Data Replication (IDR) replication issues.") | Review these status messages with recovery information. | [Table 1.
