XDCR Metrics
A list of the metrics provided by XDCR.
The following XDCR metrics can be queried by means of the REST APIs described in Statistics.

Total number of documents filtered and not replicated because the documents were ATR documents |
Number of documents filtered that were binary documents |
Given the vBuckets of this node, the number of sequence numbers that need to be processed (either replicated or handled) before catching up to the high sequence numbers for the vBuckets |
Total number of documents filtered and not replicated because the documents were transaction client records |
Amount of data replicated for a Replication |
Theoretical amount of data replicated for a Replication if compression were not used |
The total number of failed GET() operation on a reusable datapool within XDCR for the purpose of avoiding garbage generation |
The number of items sent by the Data Service waiting for the XDCR Source Nozzle to ingest and process |
The rolling average amount of time it takes for a document to be received by XDCR from the Data Service, to the time it is queued up in the Target Nozzle ready to be sent |

Number of Deletions written to Target |
Number of Deletions that failed Source-side Conflict Resolution |
Number of Deletions that failed Conflict Resolution at the Target |
Number of Deletions that were filtered Source-side |
Number of Deletions received from the Data Service |
Across vBuckets for this node, the sum of all sequence numbers that have been considered to be checkpointed |
Number of Source Document Mutation cloned to be written to different Target Namespaces |
Number of documents (or tombstones) that were not replicated to the Target due to Conflict Resolution evaluated on the Source |
Number of documents failed Conflict Resolution at the Target |
Total number of documents filtered and not replicated due to the presence of transaction related xattrs in it |
Total number of documents filtered and not replicated because of user defined filter expressions |
Total number of documents filtered and not replicated due to any type of filtering |
Number of Documents Optimistically Replicated to the Target Cluster |
Number of Documents processed for a Replication |
Number of Document Mutations received from the Data Service |
Number of Document Mutations that couldn't be filtered due to inability to parse the document through Advanced Filtering engine and were not replicated |
Number of docs Document Mutations written/sent to the Target |
Number of Expirations written to the Target |
Number of Expirations that failed Source-side Conflict Resolution |
Number of Expirations that failed Conflict Resolution at the Target |
Number of Expirations filtered Source-side |
Number of Expirations or documents with TTL received from the Data Service |
Number of Document Mutations replicated that had the TTL changed to 0 before writing to Target (Source is unmodified) |
The number of writes that target rejected because each target data node is holding too much data |
The number of writes that target rejected because a data node is running out of disk space |
The number of writes that target rejected due to the target bucket being under the resident ratio threshold |
Total number of documents filtered and not replicated because the documents were mobile records |
The number of times checkpoint operation has completed successfully since this XDCR process instance is made aware of this replication |
The number of times checkpoint operation has encountered an error since this XDCR process instance is made aware of this replication |
The number of currently present errors for a specific Replication Pipeline |
The pipeline status for a specific pipeline, where it could be paused, running or, error |
The rolling average amount of time it takes from when a MemcachedRequest is created to be ready to route to an outnozzle to the time that the response has been heard back from the target node after a successful write |
The number of seqno advance events received from source data service |
Number of Set operations successfully written to the Target |
Number of Set operations that failed Conflict Resolution at the Target |
Number of documents filtered that was of a DCP mutation |
Number of Sets received from the Data Service |
Amount of data being queued to be sent in a Target Nozzle |
The number of system events received from source data service |
The total number of EACCESS errors returned from the target node. |
The total number of TMPFAIL errors returned from the target node. |
The total number of writes to target data service that returned with a status code that XDCR cannot comprehend |
The rolling average of the latency time introduced due to bandwith throttler |
The rolling average of the latency time introduced due to throughput throttler |
The rolling average amount of time it takes for a checkpoint operation to complete |
The rolling average amount of time it takes for the source cluster to receive the acknowledgement of a SET_WITH_META response after the Memcached request has been composed to be processed by the XDCR Target Nozzle |
The rolling average amount of time it takes once a getMeta command is composed to be sent to the time the request is handled once the target node has responded |
