I ran into a multiline processing problem in Filebeat when the filebeat.inputs: parameters specify type: filestream - the logs of the file stream are not analyzed according to the requirements of multiline. pattern: '^[[0-9]{4}-[0-9]{2}-[0-9]{2}', in the output, I see that the lines are not added to the lines, are created new single-line messages with individual lines from the log file.
If you specify type: log in the file bat.inputs: parameters, then everything works correctly, in accordance with the requirements of multiline. pattern: '^[[0-9]{4}-[0-9]{2}-[0-9]{2}' - a multiline message is created.
What is not correctly specified in my config?
filebeat.inputs:
- type: filestream
enabled: true
paths:
- C:\logs\GT\TTL\*\*.log
fields_under_root: true
fields:
instance: xml
system: ttl
subsystem: GT
account: abc
multiline.type: pattern
multiline.pattern: '^\[[0-9]{4}-[0-9]{2}-[0-9]{2}'
multiline.negate: true
multiline.match: after
To get it working you should have something like this:
filebeat.inputs:
- type: filestream
enabled: true
paths:
- C:\logs\GT\TTL\*\*.log
fields_under_root: true
fields:
instance: xml
system: ttl
subsystem: GT
account: abc
parsers:
- multiline:
type: pattern
pattern: '^\[[0-9]{4}-[0-9]{2}-[0-9]{2}'
negate: true
match: after
There are 2 reasons why this works:
The general documentation at the time of this writing regarding multiline handling is not updated to reflect changes done for fileinputstream type. You can find information regarding setting up multiline for fileinputstream under parsers on this page: https://www.elastic.co/guide/en/beats/filebeat/current/filebeat-input-filestream.html
The documentation I just mentioned above is also wrong (at least at the time of this writing). The example shows configuring the multiline parsers without indenting its children, which will not work as the parser will not initialize any of the values underneath it. This issue is also being discussed here: https://discuss.elastic.co/t/filebeat-filestream-input-parsers-multiline-fails/290543/13 and I expect it will be fixed sometime in the future.

I have the same kind of log file that uses the same grok patterns to match, however they are in different folders and I want to tag them accordingly. How would I go about it?
Would something like this work:
filebeat.inputs:
- type: log
enabled: true
paths:
- /opt/IBM/WebSphere/server_one/SystemOut.log
tags: ["server_one"]
paths:
- /opt/IBM/WebSphere/server_two/SystemOut.log
tags: ["server_two"]
You can add custom fields to the events and then use conditional filtering in Logstash.
In order to do this, you need to define multiple prospectors in the Filebeat configuration. Now, group the files that need the same processing under the same prospector so that the same custom fields can be added.
More reference: https://www.elastic.co/guide/en/beats/filebeat/1.1/multiple-prospectors.html
Having multiple log entries with different tags worked.
filebeat.inputs:
- type: log
enabled: true
paths:
- /opt/IBM/WebSphere/server_one/SystemOut.log
tags: ["server_one"]
- type: log
enabled: true
paths:
- /opt/IBM/WebSphere/server_two/SystemOut.log
tags: ["server_two"]
am using filebeat to forward incoming logs from haproxy to Kafka topic but after forwarding filebeat is adding so much metadata to the kafka message which consumes more memory which I want to avoid.
Example of message sinked to kafka from filebeat where it is adding metadata, host and lot of other things:
{
"#timestamp": "2017-03-27T08:14:09.508Z",
"beat": {
"hostname": "stage-kube03",
"name": "stage-kube03",
"version": "5.2.1"
},
"input_type": "log",
"message": {
"message": {
"activityType": null
},
"offset": 3783008,
"source": "/var/log/audit.log",
"type": "log"
}
How do I control/reduce the additional metadata filebeat adds to kafka message along with the log line payload? below is my filebeat.yml file

You need to remove the additional add_host_metadata and add_cloud_metadata metadata you're adding explicitly and remove the remainder of the fields with the drop_field processor:
I've tested your configuration and changed the following:
filebeat.inputs:
- type: log
enabled: true
paths:
- /var/log/*.log
output.console:
pretty: true
processors:
- drop_fields:
fields: ["agent", "log", "input", "host", "ecs" ]
#- add_host_metadata: ~
#- add_cloud_metadata: ~
The result:
{
"#timestamp": "2020-11-27T15:55:17.098Z",
"#metadata": {
"beat": "filebeat",
"type": "_doc",
"version": "7.10.0"
},
"message": "2020-11-27 00:29:58 status installed libc-bin:amd64 2.28-10"
}
According to the documentation, you can't remove some of the metadata, namely the #timestamp and type (which should include the #metadata field).
The drop_fields processor specifies which fields to drop if a certain
condition is fulfilled. The condition is optional. If it’s missing,
the specified fields are always dropped. The #timestamp and type
fields cannot be dropped, even if they show up in the drop_fields
list.
EDIT:
Since you appear to be running filebeat 5.2.1, I've tried the following configuration with even better success than filebeat 7.x:
filebeat.prospectors:
- input_type: log
paths:
- /var/log/*.log
output.console:
pretty: true
processors:
- drop_fields:
fields: ["log_type", "input_type", "offset", "beat", "source"]
Result:
{
"#timestamp": "2020-11-30T09:51:40.404Z",
"message": "2020-11-27 00:29:58 status half-configured vim:amd64 2:8.1.0875-5",
"type": "log"
}
EDIT2:
Conversely, because you've posted a filebeat 6.8.0 version output, I've also tested with this very same version:
filebeat.inputs:
- type: log
enabled: true
paths:
- /var/log/*.log
output.console:
pretty: true
processors:
- drop_fields:
fields: ["beat", "source", "prospector", "offset", "host", "log", "input", "event", "fileset" ]
#- add_host_metadata: ~
#- add_cloud_metadata: ~
Output:

"#timestamp": "2020-11-30T10:08:26.176Z",
"#metadata": {
"beat": "filebeat",
"type": "doc",
"version": "6.8.0"
},
"message": "2020-11-27 00:29:58 status unpacked vim:amd64 2:8.1.0875-5"
}
Below is how im trying to add a custom fiels name in my filebeat 7.2.0
filebeat.inputs:
- type: log
enabled: true
paths:
- D:\Oasis\Logs\Admin_Log\*
- D:\Oasis\Logs\ERA_Log\*
- D:\OasisServices\Logs\*
processors:
- add_fields:
fields:
application: oasis
and with this, im expecting a new field called application whose data entries will be 'oasis'.
But i dont get any.
I also tried
fields:
application: oasis/'oasis'
Help me with this.
If you want to add a customized field for every log, you should put the "fields" configuration in the same level of type. Try the following:
- type: log
enabled: true
paths:
- D:\Oasis\Logs\Admin_Log\*
- D:\Oasis\Logs\ERA_Log\*
- D:\OasisServices\Logs\*
fields.application: oasis
There are two ways to add custom fields on filebeat, using the fields option and using the add_fields processor.
To add fields using the fields option, your configuration needs to be something like the one below.
filebeat.inputs:
- type: log
paths:
- 'D:/path/to/your/files/*'
fields:
custom_field: 'custom field value'
fields_under_root: true
To add fields using the add_fields processor, you can try the following configuration.
filebeat.inputs:
- type: log
paths:
- 'D:/path/to/your/files/*'
processors:
- add_fields:
target: ''
fields:
custom_field: 'custom field value'
Both configurations will create a field named custom_field with the value custom field value in the root of your document.
The fields option can be used per input and the add_fields processor is applied to all the data exported by the filebeat instance.
Just remember to pay attention to the indentation of your configuration, if it is wrong filebeat won't work correctly or even start.
Does anyone know if SAM templates support Lifecycleconfigruation settings? I see within standard cloudformation definitions you can define the lifecycle of objects like:
BucketName: "Mys3Bucket"
LifecycleConfiguration:
Rules:
- AbortIncompleteMultipartUpload:
DaysAfterInitiation: 7
Status: Enabled
- ExpirationInDays: 14
...
But this seems to fail when used in a SAM template. Am I doing something wrong or is this not part of the serverless application model definition?
It works for me using the SAM CLI 1.15.0, although documentation seems sparse (hence my landing on this question while trying to figure it out).
The SAM template snippet below successfully creates a bucket and sets an appropriate lifecycle rule.
Resources:
Bucket1:
Type: 'AWS::S3::Bucket'
Properties:
BucketName: !Sub "${BucketName}"
AccessControl: Private
VersioningConfiguration:
Status: Enabled
LifecycleConfiguration:
Rules:
- ExpirationInDays: 6
Status: Enabled
Say I want to run a task only when a specific tag is NOT in the list of tags supplied on the command line, even if other tags are specified. Of these, only the last one will work as I expect in all situations:
- hosts: all
tasks:
- debug:
msg: 'not TAG (won't work if other tags specified)'
tags: not TAG
- debug:
msg: 'always, but not if TAG specified (doesn't work; always runs)'
tags: always,not TAG
- debug:
msg: 'ALWAYS, but not if TAG in ansible_run_tags'
when: "'TAG' not in ansible_run_tags"
tags: always
Try it with different CLI options and you'll hopefully see why I find this a bit perplexing:
ansible-playbook tags-test.yml -l HOST
ansible-playbook tags-test.yml -l HOST -t TAG
ansible-playbook tags-test.yml -l HOST -t OTHERTAG
Questions: (a) is that expected behavior? and (b) is there a better way or some logic I'm missing?
I'm surprised I had to dig into the (undocumented, AFAICT) variable ansible_run_tags.
Amendment: It was suggested that I post my actual use case. I'm using ansible to drive system updates on Debian family systems. I'm trying to notify at the end if a reboot is required unless the tag reboot was supplied, in which case cause a reboot (and wait for system to come back up). Here is the relevant snippet:
- name: check and perhaps reboot
block:
- name: Check if a reboot is required
stat:
path: /var/run/reboot-required
get_md5: no
register: reboot
tags: always,reboot
- name: Alert if a reboot is required
fail:
msg: "NOTE: a reboot required to finish uppdates."
when:
- ('reboot' not in ansible_run_tags)
- reboot.stat.exists
tags: always
- name: Reboot the server
reboot:
msg: rebooting after Ansible applied system updates
when: reboot.stat.exists or ('force-reboot' in ansible_run_tags)
tags: never,reboot,force-reboot
I think my original question(s) still have merit, but I'm also willing to accept alternative methods of accomplishing this same functionality.
For completeness, and since only #paul-sweeney has offered any alternative solution, I'll answer my own question with my current best solution and let people pick / up-vote their favorite:
---
- name: run only if 'TAG' not specified
debug:
msg: 'ALWAYS, but not if TAG in ansible_run_tags'
when: "'TAG' not in ansible_run_tags"
tags: always
I know it's an old(ish) question, but I had a similar requirement.
It's probably something best implemented another way ... but ... sometimes it can be useful.
I'd achieve it by setting a fact if the tag IS specified, then outputting the message only if the fact is not set, something like:
---
- name: "test task runs only if tag missing"
hosts: all
tasks:
- name: "suppress message if tag given"
set_fact: suppress_message=yes
tags: reboot,never
- name: "message"
debug:
msg: "You didn't say 'reboot'"
when: suppress_message is not defined
I think that we have states for controlling (example: started, restarted, stopped), states for installing (present,absent) and components (webserver, db,...).
Ansible is lacking a good separation of those 3 dimensions and mixing those 3 dimensions in a single tag system is leading to confusion.
For example, if you have a 'webserver' and a 'DB' tag, you want to 'restart' the DB and not the webserver using a 'restart' tag.
But it won't work if the 'restart' tasks of the DB and the webserver are in the same tasks file with the same 'restart' tag as the 'restart' tag will start both the DB and the webserver...
So you will have probably to separate webserver and DB tasks in 2 separate files and use the tag at the level of the include.
Using tags means that you have a tree of options, not a matrix of options.
I like the tag concept but the fact that it is not possible to use it in conditional expressions is making it less appealing.
What I recommend is to declare tags in a role but map them into variables as a first task. So the 'restart' and 'db' tags would become boolean variables in my role and use when: instead of tags:
ansible-playbook has a skip-tags option. The example from the docs is
ansible-playbook example.yml --skip-tags "packages"
