Author	SHA1	Message	Date
Javier Jaramago Fernández	ebedd5e37b	Several improvements to prometheus metrics definitions ... - Metrics now follow prometheus base unit convention. - Many metrics now make use of labels instead of enconding the info in the metric name. - Almost all metrics now have a meaningful 'help' message.	5 years ago
René Cannaò	aaddb4e568	Port of #3001 to 2.1.0 , related to #3000 ... A client connection can use a backend connection with a session variable set by a different client	6 years ago
René Cannaò	6d785dc103	Changed min max_connections for Aurora autodiscovery ... Changed minimum value from 1000 to 10 (very conservative) See issue #3043	6 years ago
René Cannaò	507a68db29	Variable mysql-monitor_replication_lag_count ... Renamed variable mysql-monitor_replication_lag_retries to mysql-monitor_replication_lag_count to match other variables naming convention. As it is a counter, it minimum value is changed to 1. Maximum value sets to 10. Use of thread storage variable mysql_thread___monitor_replication_lag_count instead of GloMTH->variables.monitor_replication_lag_retries to avoid dirty reads .	6 years ago
Javier Jaramago Fernández	a2727739e4	Added new variable 'mysql-monitor_replication_lag_retries' ... This new variable controls the number of retries that replication lag needs to exceed 'max_replication_lag' in order to set a server SHUNNED.	6 years ago
Jim Riggs	601809e6fd	Log emergency check of shunned servers when no servers are available ... Issue #531 added "a desperate attempt to bring back online any shunned server" when no servers are available; however, no indication or notification of this is logged. Add a log message indicating that the hostgroup has no servers available and shunned hosts are being checked before the normal shun recovery time.	6 years ago

René Cannaò	d722bbe62a	Merge pull request #2944 from sysown/v2.1.0-2711 ... Re-enable PXC node after pxc_maint_mode is DISABLED #2711	6 years ago
René Cannaò	33d8db02a6	Change the mapping logic for SESSION_TRACK_GTIDS ... Changing the mapping logic in SESSION_TRACK_GTIDS in frontend and backend connections. Up to now, frontend and backend `SESSION_TRACK_GTIDSs match. This is now changed: * backend connections are by default set to `mysql-default_session_track_gtids` * if `mysql-default_session_track_gtids=OFF` (the default) , `session_track_gtids` is not changed on backend * if the client asks for `session_track_gtids=OFF` , proxysql ignores it (it just acknowledge it) * if the client asks for `session_track_gtids=OWN_GTID` , proxysql will apply it * if the client asks for `session_track_gtids=ALL_GTIDS` , proxysql will switch to OWN_GTID and generate a warning * if the backend doesn't support `session_track_gtids` (for example in MySQL 5.5 and MySQL 5.6), proxysql won't apply it. It knows checking server capabilities This commit also deprecates function `MySQL_Session::handler_again___verify_backend__generic_variable()` ProxySQL is now also able to know when proxysql binlog reader is perhaps in use tracking all gtid_port in mysql_servers. This feature in future will be used to deprecate `mysql-default_session_track_gtids`	6 years ago
