module: zabbix_screen
short_description: Zabbix screen creates/updates/deletes
description:
- This module allows you to create, modify and delete Zabbix screens and associated graph data.
version_added: "2.0"
author:
- "(@cove)"
- "Tony Minfei Ding"
- "Harrison Gu (@harrisongu)"
requirements:
- "python >= 2.6"
- zabbix-api
options:
server_url:
description:
- Url of Zabbix server, with protocol (http or https).
required: true
aliases: [ "url" ]
login_user:
description:
- Zabbix user name.
required: true
login_password:
description:
- Zabbix user password.
required: true
http_login_user:
description:
- Basic Auth login
required: false
default: None
version_added: "2.1"
http_login_password:
description:
- Basic Auth password
required: false
default: None
version_added: "2.1"
timeout:
description:
- The timeout of API request (seconds).
default: 10
screens:
description:
- List of screens to be created/updated/deleted(see example).
- If the screen(s) already been added, the screen(s) name won't be updated.
- When creating or updating screen(s), C(screen_name), C(host_group) are required.
- When deleting screen(s), the C(screen_name) is required.
- 'The available states are: C(present) (default) and C(absent). If the screen(s) already exists, and the state is not C(absent), the screen(s) will just be updated as needed.'
required: true
notes:
- Too many concurrent updates to the same screen may cause Zabbix to return errors, see examples for a workaround if needed.
