11.9 Help icons lead to online manual Oldtime Zabbix users might remember the days when help icons from Zabbix frontend linked to the online manual. With the conversion to online documentation that again specify regular expressions in logfile monitoring. 6.13 Online documentation Documentation from an inflexible PDF file has been converted to online format where anybody can comment on individual pages.

Zabbix 3.0.22 Item changes • system.cpu.num agent item on AIX now returns the current number of online logical processors and not the number of logical processors attached to an AIX LPAR. 28 What’s 163 Key CPU load. Float cpu - possible values: all (default), percpu (total load divided by online CPU count) mode - possible values: avg1 (one-minute average, default), avg5, avg15 Example: sys- tem.cpu.loadX system.cpu.num[] Number of CPUs. Integer type - possible values: online (default), max Example: => sys- tem.cpu.num system.cpu.switches Count of context switches

Zabbix 3.4.14 Item changes • system.cpu.num agent item on AIX now returns the current number of online logical processors and not the number of logical processors attached to an AIX LPAR. 25 Frontend 148 Key CPU load. Float cpu - possible values: all (default), percpu (total load divided by online CPU count) mode - possible values: avg1 (one-minute average, default), avg5, avg15 Example: sys- tem.cpu.loadX system.cpu.num[] Number of CPUs. Integer type - possible values: online (default), max Example: => sys- tem.cpu.num system.cpu.switches Count of context switches

system.cpu.load now accepts percpu as the first parameter - if specified, total load divided by online CPU count is returned (default is still all and returns normal load value) vm.memory.size now supports ] CPU load. Float cpu - possible values: all (default), percpu (total load divided by online CPU count) mode - possible values: avg1 (one-minute average, default), avg5 (5-minute average) since Zabbix 2.0.0. system.cpu.num[] Number of CPUs. Integer type - possible values: online (default), max Example key: system.cpu.num system.cpu.switches Count of context switches.

target machine. On *nix systems, the processors (or cores) will be reported in two states - as being ”online” or ”offline”. On Windows a third, ”unknown” state, is possible. A processor is considered to be ] CPU load.

Float cpu - possible values: all (default), percpu (since version 2.0; total load divided by online CPU count) mode - possible values: avg1 (one-minute average, default), avg5, avg15 Example: sys- tem.cpu.loadX system.cpu.num[] Number of CPUs. Integer type - possible values: online (default), max Example: => sys- tem.cpu.num system.cpu.switches Count of context switches network discovery actions are event-based, they will be triggered both when a discovered host is online and when it is offline. It is highly recommended to add an action condition Discovery status: up
