Zabbix takes more than 5 min to report an issue.

[sssdexp]

Hi,

My zabbix setup is taking at least 6+ min to report issue for some items. I have tested this multiple times on HTTP template provided by zabbix. My HTTP Item has interval of 3min.

Strange thing is that it shows correct value in latest data / graph for HTTP, aisde this it reports problem resoloved on time (i.e. as soon as it gets value). Why there is delay only for reporting issue despite having latest data too.


Zabbix: 3.0
OS: CentOS 7
No. of Hosts: 50~

Kindly help.

simple check is slow in alerting as compare to zabbix_agent

Hi,

I did some research and came to know that, when I am using Type: simple_checks in item for monitoring then I am facing at least 5 min delay for getting alert.

Type: Simple check
Key: net.tcp.service[http]
Interval: 180

But if I use Type: zabbix_agent in item then alert is instantaneous.

Type: Zabbix_agent
Key: net.tcp.listen[80]
Interval: 180

But both are quick at alert when problem get resolved. Still curious to know why simple check are slow at alert when issue occurs, but fast at alert when issue get resolved.

Got solution

Hi,

Finally I got solution, actually I was using http template provided by zabbix, in this item, they have below mentioned trigger, which was taking max of last 3 values, hence it was taking 3x more time than interval value to report issue.

{Template App HTTP Service:net.tcp.service[http].max(#3)}=0
