not fire immediately after a restored connection, but will skip the data for the delayed period. Suppression is turned on: • for passive proxies - if connection is restored more than 15 seconds and no no less than 2 & ProxyUpdateFrequency seconds later • for active proxies - if connection is restored more than 15 seconds later You may also turn off sensitiveness to proxy availability, using the new For upgraded installations, a manual patch must be applied. ODBC monitoring without DSN A new connection string parameter has been added to db.odbc.* items. Now Database monitor items can be configured

allows to customize the needed history poller instances. As each history poller requires a database connection, it is recommended to keep the number of instances as low as possible. To deal with host availability to the Oracle host. • Support of Net Service Name connection method has been added. Now Zabbix supports two types of connect identifiers (connection methods): Easy Connect and Net Service Name. See Oracle dates of TLS/SSL website certificates. • Plugins MySQL and PostgreSQL now support encrypted TLS connection between the agent and monitored databases. TLS encryption parameters can be provided in the agent

with -Dcom.sun.management.jmxremote option on the command line. Java gateway accepts incoming connection from Zabbix server or proxy and can only be used as a ”passive proxy”. As opposed to Zabbix proxy gateway starts multiple threads, controlled by the START_POLLERS option. On the server side, if a connection takes more than Timeout seconds, it will be terminated, but Java gateway might still be busy retrieving as much as possible (affected by item intervals) and send them to the Java gateway in a single connection for better performance. It is suggested to have StartJavaPollers less than or equal to START_POLLERS

Updated 10.11.X. TimescaleDB 2.10 support The maximum supported version for TimescaleDB is now 2.10. Connection options for Oracle plugin The Oracle plugin, supported for Zabbix agent 2, now allows to specify new values in the item key parameters. Previously, users had to select if they prefer to provide connection string values in a named session or in an item key. If a named session has been used, related

When the database goes up database connection re-established will be printed. There were no such messages on DebugLevel=2 previously. 5.20 odbc.discovery item has been introduced to support low-level discovery using ODBC SQL queries. A connection protocol parameter has been added to net.dns and net.dns.record agent items. The accepted values

Terminology Setting this option enforces to use TLS connection to database from Zabbix server/proxy and frontend to database: • required - connect using TLS
