Hi all,

I've got a Zabbix Server 3.4 with a Web Scenario setup. The Web scenario looks like:

Code:

Headers:
Content-Type => text/xml
Required string => "APIcheckTest1" status="up"
Required status codes => 200
URL: https://api.example.com/Ping/1.1

That works fine and I have created a trigger like:

Code:

{webserver.example.com:web.test.rspcode[API_example.com,API - APIcheckTest1].[B]min([/B]5m[B])[/B]}<>200

however, I also need another trigger for the Required string. If the required string returns anything but ("APIcheckTest1" status="up"), then triggers an alert.

Already tried this thread but it does not work for me.

Any tips?
Thanks in advance!

Hello
I think '.regex' time for web monitoring: https://www.zabbix.com/documentation...ar_expressions
Search string: (status)(=)("up") or this one ((?:[a-z][a-z]+))(.)(("up").

Do you mean "web.page.regexp[]"?

So it would be something like???

Code:

{webserver.example.com:web.page.regexp[https://api.example.com,/Ping/1.1,443,(status)(=)("up")]}

Cheers!

EDIT 1:

Tried to simulate that and I get an error from the Zabbix Server:

Code:

zabbix_get -s webserver.example.com -k "web.page.regexp[api.example.com,/Ping/1.1,443,(status)(=)("up"),10]"

ZBX_NOTSUPPORTED: HTTP get error: cannot connect to [[webserver.example.com]:443]: [4] Interrupted system call

Hello

Code:

zabbix_get -s webserver.example.com

Hello

In your example: webserver.example.com - whose is this address?

**kernbug** · 21-06-2018, 07:36

Do you have Zabbix Agent on this web server?

**lpossamai** · 26-06-2018, 08:38

Does anyone have any tips here? Still trying to figure this out....

Cheers!

UPDATE:

test.xml:

Code:

<?xml version="1.0" encoding="UTF-8"?><ping><service name="APITest1" status="up"/><service name="APIcheck1" status="down"/></ping>

Tried with (from the webserver itself):

Code:

zabbix_agentd -t 'web.page.regexp[localhost,test.xml,80,\"APITest1\"]'
Returns: [s|"APITest1"]

zabbix_agentd -t 'web.page.regexp[localhost,test.xml,80,/"APITest1" status="up"\/>/]'
Returns: web.page.regexp[localhost,test.xml,80,/"APITest1" status="up"\/>/] [s|]

**kernbug** · 28-06-2018, 07:24

Hi,

Code:

 
 zabbix_agentd -t 'web.page.regexp[localhost,test.xml,80,[COLOR=#FF0000]\"APITest1\"[/COLOR]]' Returns: [s|"APITest1"]

Yep, correct.

Code:

<?xml version="1.0" encoding="UTF-8"?><ping><service name="APITest1" status="up"/><service name[COLOR=#FF0000]="A[/COLOR]PIcheck1" [COLOR=#FF0000]status="down"[/COLOR]/></ping>

zabbix_agentd -t 'web.page.regexp[localhost,test.xml,80,[COLOR=#FF0000]/"[/COLOR]APITest1[COLOR=#FF0000]"[/COLOR] status=[COLOR=#FF0000]"up"[/COLOR]\/>/]'
Returns: web.page.regexp[localhost,test.xml,80,/"APITest1" status="up"\/>/] [s|]

Highlighted in red, if you are trying to find exact string, specify exact string to find

Also tested on my test setup:

Code:

[root@z34t]# zabbix_agentd -t 'web.page.regexp[www.apache.org,/foundation/how-it-works.html,80,[COLOR=#008000]themselves the "Apache Group"[/COLOR]]'

web.page.regexp[www.apache.org,/foundation/how-it-works.html,80,themselves the "Apache Group"] [COLOR=#0000FF][s|themselves the "Apache Group"][/COLOR]

[root@z34t]# zabbix_agentd -t 'web.page.regexp[www.apache.org,/foundation/how-it-works.html,80,[COLOR=#008000]themselves the "[/COLOR][COLOR=#FF0000]_[/COLOR][COLOR=#008000]Apache Group[/COLOR]"]'

web.page.regexp[www.apache.org,/foundation/how-it-works.html,80,themselves the "_Apache Group"] [COLOR=#0000FF][s|][/COLOR]

Hi, lpossamai

Try a trigger like this one:

{webserver.example.com:web.test.error[API_example.com,API - APIcheckTest1].regexp("required pattern")}=1 and {webserver.example.com:web.test.fail[API_example.com,API - APIcheckTest1].last()}>0

web.page.regexp[www.apache.org,/foundation/how-it-works.html,80,themselves the "_Apache Group"] [COLOR=#0000FF][s|][/COLOR]

Hi,

umm... so how can I know if it is the correct regexp? When it returns this?

Code:

[B][root@zabbix ~]# [/B]zabbix_agentd -t 'web.page.regexp[api.example.com,/Ping/1.1,443,\"APITest1\" status="up"]'
web.page.regexp[api.example.com,/Ping/1.1,443,\"APITest1\" status="up"] [s|]

If that is correct and the expression is

Code:

\"APITest1\" status="up"

, then on my Web Monitoring scenario where should I put it? In the "Required string" field?

Thanks but I first need to find out the correct regexp for it.

regexp("required pattern") is your regexp, because there is this text in "Last error message of scenario ..." item if required string not found:
required pattern "APIcheckTest1" status="up" was not found on ....

**lpossamai** · 29-06-2018, 00:10

okay.. got it...

The expression is:

Code:

 [TABLE]
[TR]
[TD]\"APITest1\" status="up"[/TD]
 		[/TR]
[/TABLE]

I changed my test.xml to status="down" and it is working. It is giving me an error that could not find the string.

Now I need to figure out the trigger.

Hi,

I managed to get the trigger working like this:

Code:

{webserver.example.com:web.test.error[Scenario].strlen()}>0 and {webserver.example.com:web.test.fail[Scenario].last()}>0

Reference: https://www.zabbix.com/documentation...nitoring/items

Thanks guys for the help!

**lpossamai** · 29-06-2018, 01:04

Is there a way to get the Web Scenario Step name on the trigger?

I.e: Failed step {STEP.NAME} on host {HOST.NAME}

Assuming by https://www.zabbix.com/forum/zabbix-...rigger-message this feature has not been implemented yet? Does anyone have a workaround this?

Cheers!
