DAY 2 EXAM
What do most Trigger functions require? - ANSWERS-/host/key i.e.
last(/prod/system.cpu.local)
In this case 'last' is the function
What is one of the most common parameters for Trigger functions? -
ANSWERS-Time i.e. 10 (seconds), 10m (minutes), #10 (10 values),
10h (hours)
What operators are supported for Trigger functions? - ANSWERS-+,-
,*,/. <, <=, >, >=, =, <>, and, or, not
True or False. It is possible to compare a function against a user
macro. - ANSWERS-True.
How can you use the last() function to return the 35th last value
received one hour ago? - ANSWERS-last(/host/key,#35:now-1h)
How often are time-based Trigger functions recalculated? -
ANSWERS-Every 30 seconds no matter what update interval is
configured (in addition to)
What does this Trigger function do?
, min(/host/system.cpu.load,30s) > 2 and dayofweek() > 5 -
ANSWERS-Detects CPU load for a minimum value of 2 every 30
seconds, only on weekdays (check this)
What are the two possible return values for the 'nodata' Trigger
function? - ANSWERS-0 = data, 1 = no data
What is the issue with using time-based functions in Triggers with
multiple event generation? - ANSWERS-It will create a new problem
every 30 seconds
What are three things that nodata() can be used to detect? -
ANSWERS-Zabbix agent availability. Changes in log files monitored
by Zabbix. Data received on regular intervals.
True or False. Zabbix supports dependencies between hosts directly. -
ANSWERS-False
When setting up Trigger dependencies, what three things will happen
to problems generated by dependent triggers? - ANSWERS-They will
be suppressed and hidden. Zabbix will not execute actions for the
dependent trigger. Dependent Trigger will be re-evaluated and follow
state of parent when parent Trigger changes state to "OK".
Does the hostname have any impact on passive checks? - ANSWERS-
No
