module: zabbix_screen
short_description: Create/update/delete Zabbix screens
description:
- This module allows you to create, modify and delete Zabbix screens and associated graph data.
author:
- "Cove (@cove)"
- "Tony Minfei Ding (!UNKNOWN)"
- "Harrison Gu (@harrisongu)"
requirements:
- "python >= 2.6"
- "zabbix-api >= 0.5.4"
options:
screens:
description:
- List of screens to be created/updated/deleted (see example).
type: list
elements: dict
required: true
suboptions:
screen_name:
description:
- Screen name will be used.
- If a screen has already been added, the screen name won't be updated.
type: str
required: true
host_group:
description:
- Host group will be used for searching hosts.
- Required if I(state=present).
type: str
state:
description:
- I(present) - Create a screen if it doesn't exist. If the screen already exists, the screen will be updated as needed.
- I(absent) - If a screen exists, the screen will be deleted.
type: str
default: present
choices:
- absent
- present
graph_names:
description:
- Graph names will be added to a screen. Case insensitive.
- Required if I(state=present).
type: list
elements: str
graph_width:
description:
- Graph width will be set in graph settings.
type: int
graph_height:
description:
- Graph height will be set in graph settings.
type: int
graphs_in_row:
description:
- Limit columns of a screen and make multiple rows.
type: int
default: 3
sort:
description:
- Sort hosts alphabetically.
- If there are numbers in hostnames, leading zero should be used.
type: bool
default: no
extends_documentation_fragment:
- community.general.zabbix
notes:
- Too many concurrent updates to the same screen may cause Zabbix to return errors, see examples for a workaround if needed.
