Monitoring replication status in Instance Data Replication
Summarize
Summary of Monitoring Replication Status in Instance Data Replication
The Instance Data Replication (IDR) Monitoring Dashboard provides a centralized interface for tracking the status of active producer and consumer replication sets, scheduled jobs, seeding requests, and license usage. Accessible by users with admin or idradmin roles, this dashboard is essential for maintaining data integrity and performance across ServiceNow instances.

Key Features
- IDR Overall Monitoring Dashboard: Monitors active producer and consumer replication sets, scheduled jobs, and seeding requests over the last seven days.
- Active Producer and Consumer Replications: Tracks data and network lag times, providing insights into replication efficiency and error statuses.
- Suite of IDR Scheduled Jobs: Includes jobs that poll for data changes and health checks for producer and consumer instances, with configurable schedules for job execution.
- IDR License and Usage SMv2 Dashboard: Monitors messages sent and received, along with detailed license information including type and allocation.
- Scheduled Replication Dashboard: Allows monitoring of scheduled replication requests, including counts of completed and failed requests.
Key Outcomes
Utilizing the IDR Monitoring Dashboard enables ServiceNow customers to:
- Quickly identify and address replication issues based on real-time data lag and status messages.
- Efficiently manage scheduled jobs and optimize replication processes for better performance.
- Ensure compliance with licensing by monitoring usage and allocation of IDR licenses.
- Track the overall health of replication activities to maintain data consistency across instances.
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.
Accessing the IDR Monitoring dashboard
Users with the admin or idr_admin role can access the dashboard.
- Navigate to .
- Choose one of the following: IDR Overall Monitoring, IDR License and Usage SMv2, or Scheduled Replication dashboard.
IDR Overall Monitoring dashboard
- Active Producer Replication Sets
- Active Consumer Replications Sets
- Suite of IDR Scheduled Jobs
- Producer Seeding Requests Within Last 7 Days
- Consumer Seeding Requests Within Last 7 Days
- Active Producer Replication Sets
- The Active Producer Replication Sets monitors your producer replication set status and
reports the data lag time between your instance and the replication queue.
Field Description Name Name of the producer replication set Replication Queue Reading Lag Time between a record change on the producer instance and the moment that it’s sent over the outbound replication queue Status Status of a replication set, either active or in error Status Message Message that describes the error status Message Queue Version Version of the Message Queue. Default is V2 (Hermes). - Active Consumer Replication Sets
- Active Consumer Replication Sets monitors your consumer replication set status, reports
the network lag time, and reports the data lag time between the producer instance and
consumer instance.
Field Description Name Name of the consumer replication set. Data Lag Time between a record change on the producer instance and the moment that it’s recorded in the consumer instance. Network Lag Time between a record change log in the outbound replication queue and the moment that it’s recorded in the consumer instance. Status Status of a replication set, either active or in error. Status Message Message that describes the error status. Message Queue Version Version of the Message Queue. Default is V2 (Hermes). - Suite of IDR Scheduled Jobs
- The suite of IDR scheduled jobs poll for data changes,
requests, and check the health of your producer and consumer instances. You can monitor the
following jobs:
Jobs Description Hermes Metrics Collection Collects metrics related to the Hermes Messaging Service. Hermes Periodic Purge Cleans obsolete cached data in the Hermes API. Hermes Topics Util Synchronizes topics across Hermes clusters. Initially, topics are created in a single Hermes cluster. This job detects new topics and creates the same topics in the remaining Hermes clusters. IDRConsumerJob Polls for record changes and seeding requests on the consumer instance in 15-second intervals. IDRDeltaConsumerJob Beginning in the San Diego release, when a consumer instance subscribes to a producer instance that is outside the local datacenter, the IDRDeltaConsumerJob job is created on the producer instance. The function is the same as the IDRConsumerJob. The three-letter code denotes the datacenter location. IDRHermesDeltaConsumer Polls for consumer record changes from the Hermes delta topic in 15-second intervals. IDRHeartBeatJob Updates information about the health of every active producer or consumer set. IDRMetadataConsumerJob Polls for metadata record changes on the consumer instance in 15-second intervals. IDRProducerJob Polls for new, updated, or deleted records in the data replication queue for a producer instance in 15-second intervals. IDRSeedingProducerJob Checks for new seeding requests coming from consumer instances. Note:You can set when your IDR scheduled jobs run and configure a periodic trigger that specifies how often the job runs.Table 1. IDR Scheduled Jobs field types Field Description Name Scheduled job name. Next Action Date and time when the job next runs. Trigger type Job that you can configure to run daily, weekly, monthly, periodically, once, on-demand, or business calendar start or end date. The trigger can repeat daily, hourly, by minute, or by second. Job ID ID of the scheduled job. State State of the job, for example, ready. - Producer Seeding Request Within Last 7 Days
- You can monitor the status of a producer seeding request within the last seven days.
Field Description Replication Set Producer set and the consumer set. Status Status of the seeding request. The status can be completed, in progress, or failed. Start Time Time that the seeding begins. End Time Time that the seeding ends. Percent Complete Percentage of the seeding request job that is complete. - Consumer Seeding Request Within Last 7 Days
- You can monitor the status of a consumer seeding request within the last seven days.
Field Description Replication Set Corresponding consumer set. Status Status of the seeding request. The status can be completed, in progress, or failed. Start Time Time that the seeding begins. End Time Time that the seeding ends. Percent Complete Percentage of the seeding request job that is complete. - IDR dashboard properties
You can access the IDR dashboard properties by navigating to .
You can change the following properties on your dashboard:Property field Description Minutes of lag before the Data Lag field are highlighted in red on the IDR Monitoring Dashboard Data Lag field that is part of the Active Consumer Replication set. If the actual lag time is greater than the time threshold that you set, the system highlights the field. The default is 15 minutes. Minutes of lag before the Network Lag field is highlighted in red on the IDR Monitoring Dashboard Network Lag field that is part of the Active Consumer Replication set. If the actual lag time is greater than the time threshold that you set, the system highlights the field. The default is 15 minutes. Minutes of lag before the system highlights the Replication Queue Reading Lag field in red on the IDR Monitoring Dashboard Replication Queue Reading Lag field that is part of the Active Consumer Replication set. If the actual lag time is greater than the time threshold that you set, the system highlights the field. The default is 15 minutes. Note:You can set the colors on the fields through the personalize list columns (v_idr_dashboard_list.do).
