Web content triggers

[Mangirdas]

Hello,

I would like to get some assistance with web page content trigger
I read all of this forum, but didn't find any working solution

My web page content looks:

 {"status":"UP","details":{"db":{"status":"UP","details":{"database":"MySQL","hello":1}}}}

and I am creating web.page.regexp where I have to get error when one of those status <>UP
So, current trigger which I am testing from command line looks okay

zabbix_agentd -t 'web.page.regexp[my.server,/health,8080,\"status"\:\"(\w*)]'
web.page.regexp[my.server,/health,8080,\"status"\:\"(\w*)] [s|"status":"UP]

but when I am starting create trigger I am always getting "Incorrect Item key"
I tried those triggers:

{my.server:web.page.regexp[my.server,/health,8080,\"status"\:\"(\w*)].str(UP)}=0

{my.server:web.page.regexp[my.server,"/health",8080,("status")(:)("UP")]}

Any help would be really appreciated.

How are you retrieving this page? Http agent? I think that it can read the response as JSON

I retrieving this page with Web scenario and yes it response as JSON code, but I didn't find anything regarding with JSON in here https://www.zabbix.com/documentation...gers/functions

[gofree]

maybe http agent for json parsing ( with jsonpath preprocessing ) - only drawback to webscenario is that you'll not get the response times

Hi. Yes http agent Item is my key to success. Now I can get all values from my page. thank you!

Now need to understand Preprocessing steps with JSON

For example I chosen JSONPath with Parameters: $.status and got:
cannot extract value from json by path "$.status": JSONPath query must start with the root object/element $.

Finally I managed everything
Preprocessing looks like->
Name -> JSONPath
Parameters -> $.status
Checked on Custom on fail
Set value to DOWN

and trigger
{my_web:test.diff()}=1
