Compression for server-proxy communication All communications between Zabbix server and all proxies, and vice versa are now unconditionally timer - timer for processing maintenances • trapper - trapper for active checks, traps, proxy communication • unreachable poller - poller for unreachable devices • vmware collector - VMware data collector value now, remote command functionality) • trapper - trapper for active checks, traps, proxy communication • unreachable poller - poller for unreachable devices • vmware collector - VMware data collector

through the preprocessing manager before being added to the history cache. Socket-based IPC communication is introduced between data gatherers (pollers, trappers, etc) and the preprocessing process. depending on number of monitored parameters and chosen database engine. Other hardware A serial communication port and a serial GSM modem are required for using SMS notification support in Zabbix. USB-to-serial SELinux status enabled in enforcing mode, you need to execute the following commands to enable communication between Zabbix frontend and server: RHEL 7 and later: # setsebool -P httpd_can_connect_zabbix

server was possible using the Zabbix sender utility or by implementing a custom JSON- based communication protocol similar to that used in Zabbix sender. Now it is also possible to send data to Zabbix is also possible to set Host name or Text column as the order column in Top hosts widget. 11 Communication framework for widgets , Dashboard widgets can now connect and communicate with each other, making timer - timer for processing maintenances • trapper - trapper for active checks, traps, proxy communication • trigger housekeeper - process for removing problems generated by triggers that have been deleted
