Blunting Zabbix web scenario

[Stefan_x96]

Hello, I have a bunch of websites that I am monitoring with following web scenario:

Update interval:30sec
Step 1: Timeout-15 ---> example.com --> code 200

And then there is a trigger:

{Zabbix server:web.test.fail[example.com].last()}=1

The issue is that time to time I get 500 error and it immediately sends emails to everyone, now that is an issue when people receive 50 fake emails during the night and want to murder me.

The steps I took are:

​​​Increase update interval to 600 sec
Timeout increase to 60sec

But I still have issues.
What I really want is to set up that the check needs to fail at least 3 times before it sends an email, but I am failing to do so.
Please if someone can help me fix my trigger or give me another suggestion.
Thanks

You could set your trigger to evaluate the last 3 values before sending:

Like beneath (check the last 3 values and if the minimal value of them is 1, triggers your trigger):

 
 {Zabbix server:web.test.fail[example.com].min(#3)}=1

Thank you for your answer brunohl , I do however have one more question. How does this differ from the number of attempts set in web scenarios?

From what I understand if I have check every 60min with a timeout of 1m, if I put no. of attempts 3 for example, it will try 3 times in a row (for 3 min) to get the code 200? And would all of those count in the trigger, so then if I have 3 attempts should I set trigger with #9?
Thanks for help

Hey,

From what I see, the Web Monitoring will return, in the end only one value for the key fail, for example. So if you put 3 attempts it will try once, if doesn't work it will try again and then again, but in the end the result will be fail = 1 (one data).

When you check last 3 values in a trigger, you would expect that each of the final result is a fail, not just one that has failed 3 times.

I would keep the 3 checks and use last 3 values in the test.

Hi, someone can help me??
i have to implement for two web apps an alerts in event of fail...


now is running only the trigger that send email when response code <> 200 and a second email when response code return = 200.


Sometimes happend (and i want to send email in this case) that the request goes in timeout(30 sec set on web scenario)

can i use only a step to verify timeout and response code in the same action?
can i use only a trigger with "OR" sintax to send email? (timeout or response code <> 200)

can you provide an example to menage the timeout??

thanks
