I want Logstash to output to Papertrail log service, how can I transform logstash output to this plain text pattern? :
<22>1 2014-06-18T09:56:21Z sendername programname - - - the log message
Okay I figured it out using logstash-output-syslog plugin:
output {
syslog {
host => ...
port => ...
protocol => "tcp"
codec => "plain"
facility => "user-level"
severity => "notice"
rfc => "rfc5424"
}
}

My Logstash server is CentOS Linux release 8.1.1911.
logstash.version"=>"7.7.0"
I have a capture of what I received on port UDP 5514 with :
nc -lvu 5514 -o log.txt

I have tried also "\<133\>" but it still appears. I have no idea what this <133> is.
P.S. I'm learning by myself since last 2 weeks.
I have these logs:

I want to combine all these lines to the same line, so I used this input in logstash:
input {
tcp {
port => 5002
codec => json
codec => multiline {
pattern => "^%{TIMESTAMP_ISO8601}"
negate => true
what => previous
}
type => "logspout-logs-tcp"
}
}
But it is not working, I don't know if it's beacuase of the empty line on the second line, if so, how can I resolve this problem? I am using logstash version 5.6.14.
Please check the below code,
input {
tcp {
port => 5002
codec => multiline {
pattern => "^%{TIMESTAMP_ISO8601}"
negate => true
what => "previous"
}
type => "logspout-logs-tcp"
}
}
I am trying to configure my Logstash to read from a specified log file. When I configure it to read from stdin it works as expected, my input results in a message from Logstash and displays in my Kibana UI.
$ cat /tmp/logstash-stdin.conf
input {
stdin {}
}
output {
elasticsearch { hosts => ["localhost:9200"] }
stdout { codec => rubydebug }
}
$./logstash -f /tmp/logstash-stdin.conf
WARNING: Could not find logstash.yml which is typically located in $LS_HOME/config or /etc/logstash. You can specify the path using --path.settings. Continuing using the defaults
Could not find log4j2 configuration at path //usr/share/logstash/config/log4j2.properties. Using default config which logs errors to the console
The stdin plugin is now waiting for input:
hellloooo
{
"#version" => "1",
"host" => "myhost.com",
"#timestamp" => 2017-11-17T16:05:41.595Z,
"message" => "hellloooo"
}
However, when I run Logstash with a file input I get no indication that the file is loaded into Logstash, and it does not show in Kibana.
$ cat /tmp/logstash-simple.conf
input {
file {
path => "/tmp/test_log.txt"
type => "syslog"
}
}
output {
elasticsearch { hosts => ["localhost:9200"] }
stdout { codec => rubydebug }
}
$ ./logstash -f /tmp/logstash-simple.conf
WARNING: Could not find logstash.yml which is typically located in $LS_HOME/config or /etc/logstash. You can specify the path using --path.settings. Continuing using the defaults

Any suggestions of how I can troubleshoot why my Logstash is not ingesting the configured file?
By default the file input plugin starts reading at the end of the file, so only lines added after Logstash starts will be processed. To read all existing lines upon startup add the option "start_position" => "beginning" to the configuration, as explained in documentation.
I have LS_JAVA_OPTS = -DproxySet=true -Dhttp.proxyHost=127.0.0.1 -Dhttp.proxyPort=8888
And yet, I see no traffic to my elasticsearch node from logstash in Fiddler.
I know my elasticsearch is up and running. When I curl it, Fiddler clearly shows the requests, so it is something about jruby that does not route requests through Fiddler.
I am not calling jruby directly. Rather I use the bin\logstash.bat script.

PS E:\logstash-2.3.2\bin>
As you can see, http://ncesearch01:9200/logstash-*/_count returns incremented count, hence running logstash did send a request to the elasticsearch. However, it bypassed Fiddler, despite the LS_JAVA_OPTS.
I find some possible reasons for this condition，although I did not try.May this answer should be called "discussion"，I`m sorry.
1.You may need a linux OS instead of windows，for the reason，
I am not sure this question has been deal in the latest logstash version
you may be interested in this,Make JAVA_OPTS and LS_JAVA_OPTS work consistently on Windows
2.As we see，the most possible is that
logstash ES_output plugin use the http way to send message
after logstash-2.0,you may use the old version?

If anyone has any ideas,your share will be expected~
I've been trying to do this all day. I want to send logs from Docker to FluentD via the fluentd logging engine and then from fluentd send those logs to logstash for processing.
I keep getting this error from logstash though:
{:timestamp=>"2016-03-09T23:29:19.388000+0000",

fairly basic logstash config:
input {
tcp {
port => 4000
codec => "fluent"
}
}
output {
stdout {
}
}
fairly basic fluentd config:
<source>
#type forward
</source>
<match docker.json>
#type forward
send_timeout 60s
recover_wait 10s
heartbeat_type none
phi_threshold 16
hard_timeout 60s
<server>
name logstash
host 172.18.0.2
port 4000
weight 60
</server>
</match>
<match docker.**>
#type stdout
</match>
One would think this would work, but I've already found that Logstash won't:
Work with fluentd's forward_out heartbeat configuration.
Logstash doesn't open a UDP port on the same port as the TCP.
The above error.
The above configuration does work if I craft Fluentd message pack messages in Ruby and send them manually.The key though is I want Fluentd to manage the logs locally and send them to an external logstash server to process the messages correctly into JSON.
We found a way to make fluent -> logstash work. Set time_as_integer true. A minimal configuration on the fluentd side would be
<source>
#type http
#id input_http
port 8888
</source>
<match **>
#type forward
time_as_integer true
<server>
host localhost
port 24114
</server>
</match>
It's mentioned quite hidden in https://docs.fluentd.org/v0.12/articles/in_forward#i-got-messagepackunknownexttypeerror-error-why .
On the logstash side, use a recent release (6.2.4), then simply configure the fluent codec, tcp input like this:
input {
tcp {
codec => fluent
port => 24114
}
}
filter {
}
output {
stdout { codec => rubydebug }
}
test with
curl -X POST -d 'json={"json":"message"}' http://localhost:8888/debug.test
as in the documentation. With the time_as_integer setting, the logstash output will look nice, like.
{
"port" => 32844,
"#version" => "1",
"host" => "localhost",
"json" => "message",
"#timestamp" => 2018-04-26T15:14:28.000Z,
"tags" => [
[0] "debug.test"
]
}
Without it, I get
[2018-04-26T15:16:00,115][ERROR][logstash.codecs.fluent ] Fluent parse error, original data now in message field {:error=>#<MessagePack::UnknownExtTypeError: unexpected extension type>, :data=>["fluent.info", "\x92\xD7\u0000Z\xE1\xEC\xF4\u0006$\x96傦worker\u0000\xA7message\xD9&fluentd worker is now running worker=0", {"size"=>1, "compressed"=>"text"}]}

}
AFAIK, there's no way to transport data from Fluentd to Logstash. We need to write any Fluentd output plugins to send data to Logstash, or to write any Logstash input plugins to receive data from Fluentd.
FYI: there are some plugins for direction of Logstash -> Fluentd:
fluent-plugin-beats (fluentd input plugin for Elastic beats protocol)
logstash-output-fluentd (logstash output plugin to send data to Fluentd)
You can forward it directly to logstash tcp input.
This open-source flunetd output plugin will send the data directly to logstash tcp input (or any other receiver) in json format (also supports ssl/tls).
seen first at this question.
