I have log file with vert.x logs that i want to show in Kibana. How do i phrase following log, I want to phrase only IP, Request and Response time.
Here is my sample log.
[vert.x-eventloop-thread-7] 2016-09-27T07:13:53.263Z INFO [com.term.local.rest.server.Server] SUCCESS RESPONSE : 1.get.mydata, remoteIp : 192.168.1.1, processing time : 115
From this log i want only following information to visualise in Kibana
SUCCESS RESPONSE : 1.get.mydata, remoteIp : 192.168.1.1, processing time : 115
grok {
match => {
"message" => [
"%{GREEDYDATA}SUCCESS RESPONSE : %{NOTSPACE:response}, remoteIp : %{IP:remoteip}, processing time : %{INT:proceesingTime}"
]
}
}

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 am new to elk my sample log is look like
2017-01-05T14:28:00 INFO zeppelin IDExtractionService transactionId abcdef1234 operation extractOCRData received request duration 12344 exception error occured
my filebeat configuration is below
filebeat.prospectors:
- input_type: log
paths:
- /opt/apache-tomcat-7.0.82/logs/*.log
document_type: apache-access
fields_under_root: true
output.logstash:
hosts: ["10.2.3.4:5044"]
And my logstash filter.conf file:
filter {
grok {
match => [ "message", "transactionId %{WORD:transaction_id} operation %{WORD:otype} received request duration %{NUMBER:duration} exception %{WORD:error}" ]
}
}
filter {
if "beats_input_codec_plain_applied" in [tags] {
mutate {
remove_tag => ["beats_input_codec_plain_applied"]
}
}
}
;
In kibana dashboard i can see log output as below
beat.name:
ebb8a5ec413b
beat.hostname:

1 First question is how to remove filebeat tag like id,hostname,version,grok_failure message
2 how to sort logs on timestamp basis because Newly generated logs not appearing on top of kibana dashboard
3 Is there any changes required in my grok filter
You can remove filebeat tags by setting the value of fields_under_root: false in filebeat configuration file. You can read about this option here.
If this option is set to true, the custom fields are stored as
top-level fields in the output document instead of being grouped under
a fields sub-dictionary. If the custom field names conflict with other
field names added by Filebeat, the custom fields overwrite the other
fields.
you can check if _grokparsefailure is in tags using, if "_grokparsefailure" in [tags] and remove it with remove_tag => ["_grokparsefailure"]
Your grok filter seems to be alright.
Hope it helps.
I'm using logstash with a configuration input{rabbitmq} filter{grok} output{elastic}
From rabbit I receive nginx logs in this format :
- - [06/Mar/2017:15:45:53 +0000] "GET /check HTTP/1.1" 200 0 "-" "ELB-HealthChecker/2.0"
and I'm using grok filter as simple as follow :
filter{
if [type] == "nginx" {
grok{
match => { "message" => "%{NGINXACCESS}" }
}
}
}
and the pattern is
NGUSERNAME [a-zA-Z\.\#\-\+_%]+
NGUSER %{NGUSERNAME}
NGINXACCESS %{NGUSER:ident} %{NGUSER:auth} \[%{HTTPDATE:timestamp}\] "%{WORD:verb} %{URIPATHPARAM:request} HTTP/%{NUMBER:httpversion}" %{NUMBER:response} (?:%{NUMBER:bytes}|-) (?:"(?:%{URI:referrer}|-)"|%{QS:referrer}) %{QS:agent}
I tried the pattern in grok debugger and it seems to work just fine but running the pipeline i get this error
[2017-03-06T16:46:40,692][ERROR][logstash.codecs.json ] JSON parse error, original data now in message field {:error=>#, :data=>"- - [06/Mar/2017:16:46:40 +0000] \"GET /check HTTP/1.1\" 200 0 \"-\" \"ELB-HealthChecker/2.0\""}
it seems like someone(logstash?) is adding \ to the result...
hope to get some help, thanks!
This does not seem to be a grok error at all. if grok fails to parse it will add a tag _grokparsefailure to your event. A JSON parse error would be due to your input trying to read codec => json {} when your log format is plainly not JSON. Make sure that your input plugin that is handling these log types is using codec => plain or an appropriate type.
See logstash codecs for more info.
I'm trying to run Logstash in an EC2 Ubuntu instance,
but when I run:
logstash-5.2.0/bin/logstash -f logstash.conf --debug
I get:
Starting puma
Trying to start WebServer {:port=>9600}
start
Trying to start WebServer {:port=>9601}
[api-service] start
Successfully started Logstash API endpoint {:port=>9601}
PeriodicPoller: Stopping

This is logstash.conf
input
{
http
{
host => "127.0.0.1"
port => 31311
}
}
output
{
elasticsearch
{
hosts => ["localhost:9200"]
}
stdout
{
codec => rubydebug
}
}
When I run
curl 'http://localhost:9200/?pretty'
I get:
{
"name" : "QrRfI_U",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "LLdvAaAsQSCULTfl_b4xIA",
"version" : {
"number" : "5.2.0",
"build_hash" : "24e05b9",
"build_date" : "2017-01-24T19:52:35.800Z",
"build_snapshot" : false,
"lucene_version" : "6.4.0"
},
"tagline" : "You Know, for Search"
}
So elasticsearch is running fine.
What if you have your hosts as:
hosts => "localhost"
And make sure that the http port which you've mentioned above is not bound to any other process.
If that's not the case just to make sure, run plugin list and check whether http-input plugin does exist.
Installed an ELK server via: https://www.digitalocean.com/community/tutorials/how-to-install-elasticsearch-logstash-and-kibana-elk-stack-on-centos-7
It seems to work except for the filebeat connection; filebeat does not appear to be forwarding anything or at least I can't find anything in the logs to indicate anything is happening.
My filebeat configuration is as follows:
filebeat:
prospectors:
-
paths:
- /var/log/*.log
- /var/log/messages
- /var/log/secure
encoding: utf-8
input_type: log
timeout: 30s
idle_timeout: 30s
registry_file: /var/lib/filebeat/registry
output:
logstash:
hosts: ["my_elk_fqdn:5044"]
bulk_max_size: 1024
compression_level: 3
worker: 1
tls:
certificate_authorities: ["/etc/pki/tls/certs/logstash-forwarder.crt"]
shipper:
logging:
to_files: true
files:
path: /var/log/filebeat
name: filebeat.log
rotateeverybytes: 10485760 # = 10MB
keepfiles: 7
level: debug
The log file output I keep getting from filebeat is just not very helpful:
2016-07-14T17:32:21-04:00 DBG Start next scan
2016-07-14T17:32:31-04:00 DBG Start next scan
2016-07-14T17:32:41-04:00 DBG Start next scan
2016-07-14T17:32:46-04:00 DBG Flushing spooler because of timeout. Events flushed: 0
2016-07-14T17:32:51-04:00 DBG Start next scan
Is there anything wrong with my configuration file?
When I test on the ELK server to see if I am getting anything:
[root#my_elk_server ~]# curl -XGET 'http://localhost:9200/filebeat-*/_search?pretty'
{
"took" : 1,
"timed_out" : false,
"_shards" : {
"total" : 0,
"successful" : 0,
"failed" : 0
},
"hits" : {
"total" : 0,
"max_score" : 0.0,
"hits" : [ ]
}
}
Oh and my logstash configuration for filebeats:
input {
beats {
port => 5044
ssl => true
ssl_certificate => "/etc/pki/tls/certs/logstash-forwarder.crt"
ssl_key => "/etc/pki/tls/private/logstash-forwarder.key"
}
}
UPDATE: It is not filebeat. Somewhat relieved that messages are indeed being passed but still have an issue I can't track:
Discovered it wasn't filebeat that was causing the issue. It appears that the configuration file in logstash to send to elasticsearch is not properly labeling the index (and the type) to make it searchable as shown in the question. Instead of putting filebeat in the index name it gives a result like this:
"_index" : "%{[#metadata][beat]}-2016.07.14",
The elasticsearch output put in the file turned out to be incorrect in the
output {
elasticsearch {
hosts => "my_elk_fqdn:9200"
sniffing => true
manage_template => false
index => "%{[#metadata][beat]}-%{+YYYY.MM.dd}"
document_type => "%{[#metadata][type]}"
}
}
Apparently this #metadata is not being passed in correctly. Has anyone been able to get the _index and _type fields to populate correctly???
This might be a bug with filebeat??
