# Configuration "Without template"

The configuration template "Without template" is available to users to build his own algorithm for processing the incoming stream, by writing his own handlers in Lua, or selecting handlers from the list provided.

# Tasks

There are no predefined tasks for this configuration template. Users can add new tasks.

# Handlers

There are no predefined handlers for this configuration template. Users can add new handlers.

# Configuration "AnyStream default"

The configuration template "AnyStream default" is used for all non-standard source connections. The principle of transferring primary data is based on an authorized POST request to the Acure public API.

Events received by such a stream are sent for processing to the "Synthetic Trigger" prefilter. If this processing is not required, select the configuration template "Without template".

# Tasks

There are no predefined tasks for this configuration template. Users can add new tasks.

# Handlers

In the template "AnyStream default" there is a predefined handler - Routing for Any stream, which puts the label postRouting: cl.stream-ready-event.new for further event routing. Users can add new handlers to the existing one.

# Configuration "Zabbix default"

The configuration template is designed to integrate the Acure system with a Zabbix monitoring system.

# Tasks

Users can add new tasks to the preset ones.

# Handlers

In the template "Zabbix default" there is a pre-installed handler - Routing for Zabbix stream, which sets the following labels for further event routing:

type: Zabbix,
postRouting: cl.stream-ready-event.zabbix.new

labels_add('type', 'Zabbix')
labels_add('postRoutings',{'cl.stream-ready-event.zabbix.new'})
next_step(source)

Users can add new handlers to the existing one.

# Configuration "SCOM default"

- Agent - SharedAgents - system agent by default, can be changed to an external agent.
- Default launching interval is 30 sec.

Users can add new tasks to the preset ones.

# Handlers

In the template "SCOM default" there is a pre-installed handler - Routing for Scom stream, which sets the following labels for further event routing:

type: SCOM,
postRouting: cl.stream-ready-event.new.

labels_add('postRoutings',{'cl.stream-ready-event.new'})
next_step(source)

Users can add new handlers to the existing one.

# Configuration "Prometheus default"
