7.3.4. target ¶

Default value:

Optional:

Yes

Comma separated list of event ids starting with an exclamation mark.
Leave empty to handle all events.

From version:

2.10.0

Description:

Define a comma separated list of event ids to have the event handler triggered only for those events.

When you want to have it triggered for all the events, excepting a few events you should prefix each event id with the exclamation mark (!).

Leave it empty to handle all events.

Defines the list of event groups for which this handler is active.

When you want to handle all the events, except for the ones from a set of groups, prefix the group names with the exclamation mark (!).

An event can be a member of one or multiple groups. The event is handled if any of its groups is found in the list of configured allowed groups. The event is not handled if any of its groups is found in the list of configured ignored groups (starting with !).

Leave it empty to handle events from all groups.

7.3.9. data_filter ¶

Default value:

Optional:

Yes

Values:

Comma-separated list of data member names and filter expressions.
Multiple expressions, one per line (Since 4.29.0)
Leave empty to handle all events.

From version:

3.22.0

Description:

Comma separated definition with the name of attribute data member and the targeted matching expression.

Data member names are configured with insensitive cases.

For more details about the available expressions see the matching expression documentation.

The following example will extract the value to be matched/filtered from the path data member of the event. The extracted value is then matched against the */folderA/* globbing expression:

[event-handlers/b904ed23-a234-4ccf-8abd-edcae4d3324f]
data_filter = path, */folderA/*

See the usage instructions for more operational details.

You can filter based on multiple data members using multiple rules. Each rule is defined on a separate line.

In the following example, events are triggered only if they are uploaded into the directory named reports-A with a size of 0 bytes (empty file):

[event-handlers/b904ed23-a234-4ccf-8abd-edcae4d3324f]
data_filter =
    path, */reports-A/*
    size, 0

Leave this configuration empty to not filter based on the event's attached data, and handle events regardless of their data attributes.

3.0.0

Values:

An integer number greater than 0.

Second value is the the full path matching expression. Globbing expression or regular expression can be used. For more details see the matching expression documentation.

The remaining values are paths to which the file is dispatched. The file is dispatched into the configured destinations observing the configured order. Certain actions do not need a destination path.

When regular expressions are used for the path matching configuration, the destination path can be dynamically generated based on regex matching groups and event specific variables.

The following variables (case-insensitive) are provided as context data containing information about the event being triggered:

id

message
account.name
account.email
account.peer.address
