# Discover replication delays in Instance Data Replication
Monitor possible data replication issues by using the Instance Data Replication \(IDR\) Monitoring Dashboard.
## Before you begin
Role required: admin
## About this task
## Procedure
1. To view the time lag on a producer instance, navigate to **Instance Data Replication** > **Monitoring Dashboard**, and check the Active Producer Replication Sets for the following details.
|
**Name**
|
Name of the producer replication set.
|
|
**Replication Queue Reading Lag**
|
Time between a record change on the producer instance and the moment it is 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 \(Hermes\).
|
To get additional information, view the producer instance xmlstats at `https:///xmlstats.do?include=idr`.
\[Omitted image "xmlstats-producer.png"\] Alt text: Producer instance xmlstats
The xmlstats shows:
- The *producer\_last\_run* indicates the last time that the replication job ran on the producer instance.
- The *last\_message\_sent\_on* indicates the last time that the producer sent updated data to consumers.
**Note:** The timestamps are GMT.
2. To view the time lag on a consumer instance, navigate to **Instance Data Replication** > **Monitoring Dashboard** and check the Active Consumer Replication Sets for the following details.
|
**Name**
|
Name of the consumer replication set.
|
|
**Data Lag**
|
Time between a record change on the producer instance and the moment it is recorded in the consumer instance.
|
|
**Network Lag**
|
Time between a record change logs in the outbound replication queue and the moment it is 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 \(Hermes\)
|
To get additional information, view the consumer instance xmlstats at `https:///xmlstats.do?include=idr`. \[Omitted image "xmlstats-consumer.png"\] Alt text: Consumer xmlstats The xmlstats shows:
- The *consumer\_last\_run* indicates the last time that the consumer job ran and received changes from the producer.
- The *last\_heartbeat\_received\_on* shows the timestamp when the consumer last received a heartbeat from the producer instance.
**Note:** The timestamps are GMT.
