Alerts were sent out one by one In the new version, parallel processing of alerts is implemented. There is a new alert manager process that can distribute alerts to several ”worker” processes, if needed. Media types are processed in Attempts and Retry interval: • Functionality of the database watchdog process has been merged into the alert manager and the watchdog process itself removed. 6 Improved notifications 6.1 Notification on problem

All errors had to be handled using one and the same option for error handling - either to frontend locations except the Data collection section. A new configuration syncer worker server process has been added that is responsible for resolving and synchronizing the user macro values in item

trigger prototypes has been optimized by reducing the number of SQL statements. As a result, the process of creating triggers takes only half of the time as before. 5.10 Multiple OID support in SNMP discovery Performance improvements The process of trigger expression evaluation has been improved dramatically by using a hashing mechanism. Also configuration cache locking during that process has been reduced multiple performance. 23 5.21 Item changes/improvements A new proc.cpu.util item has been added to monitor process CPU utilisation. This item is supported on Linux and Solaris platforms. net.udp.service and net
