Doctl / Retrieve Replica Information
Retrieve Replica Information
Retrieve information about a specified database replica.
doctl d r g <database_id> <replica_name> doctl d r g <database_id> <replica_name> #!/bin/bash
# Retrieve Replica Information
doctl {{[d|databases]}} {{[r|replica]}} {{[g|get]}} {{database_id}} {{replica_name}} import subprocess
# Retrieve Replica Information
# Make sure to replace <placeholders> with actual values

run_command() When To Use
When assessing the status and configuration of database replication across clusters.
Pro Tip
Monitor replica lag times to assess synchronization issues.
Command Builder
Tune the command before you copy it
doctl d r g <database_id> <replica_name> Anatomy of Output
Understanding the result
Replica Name: reporting-replica Replica Name The defined name of the database replica.
Status: Active Replica Status Current operational status of the replica.
Lag: 2 seconds Replication Lag Indicates the time lag between primary and replica.
Power User Variants
Optimized versions
doctl databases replica get 678901 reporting-replica --verbose Retrieve detailed replica information.
doctl databases replica get 678901 reporting-replica --format json Format the output in JSON for parsing.
Troubleshooting
Common pitfalls
Error: Replica not found for the given database ID.
Solution: Ensure the replica name matches the actual replica.
Error: Database ID is invalid.
Solution: Verify the database ID is active and correctly entered.
Error: Failed to retrieve information due to a timeout.
Solution: Check the database connectivity and retry the command.
