. See Working with plugins for more details.
Getting Help
editFor questions about the plugin, open a topic in the Discuss forums. For bugs or feature requests, open an issue in Github. For the list of Elastic supported plugins, please consult the Elastic Support Matrix.

Also see Common Options for a list of options supported by all input plugins.
content_type
edit- Value type is string
-
Default value is
"text/plain"
For multipart messages, use the first part that has this content-type as the event message.
host
edit- This is a required setting.
- Value type is string
- There is no default value for this setting.
password
edit- This is a required setting.
- Value type is password
- There is no default value for this setting.
sincedb_path
edit- Value type is string
- There is no default value for this setting.
Path of the sincedb database file (keeps track of the UID of the last processed
mail) that will be written to disk. The default will write sincedb file to
<path.data>/plugins/inputs/imap
directory.
NOTE: it must be a file path and not a directory path.
uid_tracking
edit- Value type is boolean
-
Default value is
false
When the IMAP input plugin connects to the mailbox for the first time and
the UID of the last processed mail is not yet known, the unread mails are
first downloaded and the UID of the last processed mail is saved. From
this point on, if uid_tracking
is set to true
, all new mail will be
downloaded regardless of whether they are marked as read or unread. This
allows users or other services to use the mailbox simultaneously with the
IMAP input plugin. UID of the last processed mail is always saved regardles
of the uid_tracking
value, so you can switch its value as needed. In
transition from the previous IMAP input plugin version, first process at least
one mail with uid_tracking
set to false
to save the UID of the last
processed mail and then switch uid_tracking
to true
.
Common Options
editThe following configuration options are supported by all input plugins:
Details
edit
codec
edit- Value type is codec
-
Default value is
"plain"
The codec used for input data. Input codecs are a convenient method for decoding your data before it enters the input, without needing a separate filter in your Logstash pipeline.
enable_metric
edit- Value type is boolean
-
Default value is
true
Disable or enable metric logging for this specific plugin instance by default we record all the metrics we can, but you can disable metrics collection for a specific plugin.
id
edit- Value type is string
- There is no default value for this setting.
Add a unique ID
to the plugin configuration. If no ID is specified, Logstash will generate one.
It is strongly recommended to set this ID in your configuration. This is particularly useful
when you have two or more plugins of the same type, for example, if you have 2 imap inputs.
Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.
input { imap { id => "my_plugin_id" } }
tags
edit- Value type is array
- There is no default value for this setting.
Add any number of arbitrary tags to your event.
This can help with processing later.
type
edit- Value type is string
- There is no default value for this setting.
Add a type
field to all events handled by this input.
Types are used mainly for filter activation.
The type is stored as part of the event itself, so you can also use the type to search for it in Kibana.
If you try to set a type on an event that already has one (for example when you send an event from a shipper to an indexer) then a new input will not override the existing type. A type set at the shipper stays with that event for its life even when sent to another Logstash server.
