Trigger not created correctly

[bbx-github]

The triggers never get created (Zabbix 5.0) The Webscenarios are working though. I have to delete them again every time I am testing because otherwise it wont even try to start creating the triggers again.

I used this as my trigger template in the .yml file: value: "last(/${HOST}/web.test.fail[Check index page '${URL}'])<>0" since this exact trigger is already working after I set it up manually. Something seems messed up in the way the expression is put together I think. It seems to add <>0 on the end for example.

Any help is appreciated.

Thanks for report. Please, post log here with --log-level=debug.

This is the part about trigger creation that shows up for every single item.

I'll check and come back

[lebe-dev]

You noticed that your Zabbix version is v5, not sure about syntax. We have Zabbix v6 and triggers look like this:

last(/somesrv.ourcompany.com/web.test.fail[Check index page 'https://somesrv.ourcompany.com'])<>0

I've never seen syntax last(...) for Zabbix 5. I think your trigger should be look like this:

someserv.ourcompany.com:web.test.fail[Check index page 'someserv.ourcompany.com'].last()

Could you provide config wszl.yml?

[bbx-github]

First, sorry about the confusion I thought I was using Zabbix 5, but in fact I am also using 6.0.

But, I dont think it happens because I defined the trigger wrongly. As I said I am already using the exact same definition in a manually created trigger and it works. But I can show you my wszl.yml:

zabbix:
  api:
    version: 6
    endpoint: https://zabbix.server.org/zabbix/api_jsonrpc.php
    username: user
    password: 'password,'

  trigger:
    name: "Site '${URL}' on '${HOST}' is unavailable"

    # Zabbix 6
    # Template variables are supported: ${HOST}, ${URL}
    #value: "last(/${HOST}/web.test.fail[Check index page '${URL}'])<>0"

    # Zabbix 5
    # Template variables are supported: ${HOST}, ${URL}
    #value: "${HOST}:web.test.fail[Check index page '${URL}'].last()"

    # Custom
    # copied from working trigger
    value: "last(/${HOST}/web.test.fail[Check index page '${URL}'])<>0"

  scenario:
    # Template variables are supported: ${HOST}, ${URL}
    name: "Check index page '${URL}'"
    response-timeout: "15s"
    expect-status-code: "200"
    attempts: 3
    update-interval: "5m"

As you can see the custom one is even the exact same trigger then the predefined one. The trigger that I manually created and is working (for a manually defined web scenario): last(/myerver.net/web.test.fail[Availability of mysite.org])<>0

[lebe-dev]

Please try new build https://github.com/tinyops-ru/zabbix-lld-ws/releases/tag/0.7.1-2

If problem will appear again, send me piece of log

[bbx-github]

Yes, it works now. But the functionality of not skipping the trigger creation when there is a web scenario already is gone again. You fixed this in another release of a different issue I created. Was this intentional. If yes, then I will close it, otherwise this may be a regression bug?

[lebe-dev]

Could you provide the latest log file with DEBUG logging mode?

[bbx-github]

What I did:

• Deleted all the created triggers but not the web scenarios
• ran sudo -u zabbix ./wszl --log-level=debug gen
• No Triggers were created

The debug log, but I cut out everything but one vhost, so I dont have to censor the whole thing:

EDIT: I did this with the latest 0.7.1.-2 release of course

[lebe-dev]

@bbx-github is the problem still relevant? sorry, i missed this issue somehow.

[lebe-dev]

I've release a new version 0.7.2 https://github.com/tinyops-ru/zabbix-lld-ws/releases/tag/0.7.2

Web scenarios and triggers are now independent of each other.
