Zabbix trigger expression

I have one item with the two possible value of a string.

OK and ERROR,

I need trigger expression with will switch trigger to Problem only when 20 last value is 'ERROR' and will switch to OK only when all 20 last value will be OK.

I was testing with {iteam.count(120,error,"like")}>1 or with regexp but it return 1 at each change occurrence.

Solution

  • Problem only when last 20 values is 'ERROR':

    {item.count(#20,error,"like")}>19

    Trigger version with hysteresis (switch to OK only when last 20 values will be OK) is left as an exercise for the reader :)
