Astra Linux 1.7 SE "Orel" is supported in ADPG Enterprise edition

A connection pooler is implemented based on PgBouncer in ADPG Enterprise edition. ADCM UI now contains the PgBouncer settings for the ADPG and Balancer services. For ADPG: Enable PgBouncer, listen_port, pool_mode, max_client_conn, default_pool_size, min_pool_size, reserve_pool_size, reserve_pool_timeout, max_db_connections, max_user_connections, Enable all users, Users list, Enable all databases, Databases list, Use custom pg_hba.conf и Custom pg_hba.conf. For Balancer: pgbouncer_leader_port, pgbouncer_replica_port.

The Force reconfigure and restart checkbox is added to the Reconfigure & Restart action settings. Force reconfigure and restart disables validation of the configuration settings before restarting ADPG

The port that PgBouncer listens on cannot be changed for a running cluster (the listen_port PgBouncer parameter of the ADPG service). After changing the port, you must execute Reconfigure & Restart action of the ADPG service

The new monitoring system is implemented. Added the Metrics storage service that can collect metrics from multiple ADPG clusters. For information on the installation of the new monitoring system, refer to Install monitoring

ADCM UI now contains the following monitoring cluster settings: Use external ADPG cluster for monitoring, External ADPG cluster [ip_address:port], Monitoring db name, Monitoring username, and Monitoring user password

The following settings of the new Metrics storage service are available in ADCM UI: Monitoring db name, Monitoring username, Monitoring user’s password, Grafana TCP port, and Grafana admin’s password

Since the new built-in monitoring system is implemented, ADPG no longer supports the integration with the Monitoring cluster. If you want to upgrade to version ADPG 14.3.4 from previous versions via automatic updates, you have to configure the monitoring system manually.

If you upgrade from ADPG Community 14.3.4 to Enterprise 14.3.4, you also need to configure monitoring manually, since the Community version does not support load balancing, which is necessary for monitoring
