Hello @amit devi
Thank you for posting in Q & A forum.
Azure Database for PostgreSQL provides various metrics that give insight into the behavior of the resources supporting the PostgreSQL server. Each metric is emitted at a one-minute frequency, and has up to 93 days of history.
You can configure alerts on the metrics. For step by step guidance, see How to set up alerts
These metrics are available for Azure Database for PostgreSQL:
Error
Failed Connections | connections_failed | Count | The number of established connections that failed. |
Latency
Max Lag Across Replicas | pg_replica_log_delay_in_bytes | Bytes | The lag in bytes between the primary and the most-lagging replica. This metric is available on the primary server only. |
Replica Lag | pg_replica_log_delay_in_seconds | Seconds | The time since the last replayed transaction. This metric is available for replica servers only. |
Saturation
Backup Storage Used | backup_storage_used | Bytes | The amount of backup storage used. This metric represents the sum of storage consumed by all the full database backups, differential backups, and log backups retained based on the backup retention period set for the server. The frequency of the backups is service managed and explained in the concepts article. For geo-redundant storage, backup storage usage is twice that of the locally redundant storage. |
CPU percent | cpu_percent | Percent | The percentage of CPU in use. |
IO percent | io_consumption_percent | Percent | The percentage of IO in use. (Not applicable for Basic tier servers.) |
Memory percent | memory_percent | Percent | The percentage of memory in use. |
Server Log storage limit | serverlog_storage_limit | Bytes | The maximum server log storage for this server. |
Server Log storage percent | serverlog_storage_percent | Percent | The percentage of server log storage used out of the server's maximum server log storage. |
Server Log storage used | serverlog_storage_usage | Bytes | The amount of server log storage in use. |
Storage limit | storage_limit | Bytes | The maximum storage for this server. |
Storage percentage | storage_percent | Percent | The percentage of storage used out of the server's maximum. |
Storage used | storage_used | Bytes | The amount of storage in use. The storage used by the service may include the database files, transaction logs, and the server logs. |
Traffic
Active Connections | active_connections | Count | The number of active connections to the server. |
Network Out | network_bytes_egress | Bytes | Network Out across active connections. |
Network In | network_bytes_ingress | Bytes | Network In across active connections. |
