input
beats
port => 5044
codec => json
type => "SuricataIDPS"
My Logstash config file is the following:
output
elasticsearch
hosts => ["localhost:9200"]
sniffing => true
manage_template => false
index => "%{[#metadata][beat]}-%{+YYYY.MM.dd}"
#document_type => "%{[#metadata][type]}"
I'd like to be able to rename the field alert.signature,
How can I do so?... Seems that it does not recognize that field...
Thanks for your help!

You have to define mutate filter within filter stanza:
filter {
mutate {
rename => [ "[alert][signature]", "[alert][signature_renamed]" ]
}
}

I'm currently discovering elastic search, kibana and logstash with docker. (Version 7.1.1) The three containers are running well.
I have some data files containing some lines like this one:
foo=bar type=alpha T=20180306174204527
My logstash.conf contains:
input {
file {
path => "/tmp/data/*.txt"
start_position => "beginning"
}
}
filter {
kv {
field_split => "\t"
value_split => "="
}
}
output {
elasticsearch { hosts => ["elasticsearch:9200"] }
stdout {
codec => rubydebug
}
}
I handle this data:
{
"host" => "07f3051a3bec",
"foo" => "bar",
"message" => "foo=bar\ttype=alpha\tT=20180306174204527",
"T" => "20180306174204527",
"#timestamp" => 2019-06-17T13:47:14.589Z,
"path" => "/tmp/data/ucL12018_03_06.txt",
"type" => "alpha"
"#version" => "1",
}
First step of job is done.
Now I want to add a filter to transform the value of the key T as a timestamp.
{
...
"T" => "2018-03-06T17:42:04.527Z",
"#timestamp" => 2019-06-17T13:47:14.589Z,
...
}
I do not know how to do it. I tried to add a second filter just after the kv filter, but nothing change when I add new files.
Add this filter after the kv filter:
date {
match => [ "T", "yyyyMMddHHmmssSSS" ]
target => "T"
}
The date filter will try to parse the field T using the provided pattern to create a date, which will be written to the T field (by default it overwrite the #timestamp field).
Data missed a lot in logstash version 5.0,
is it a serous bug ,when a config the config file so many times ,it useless,data lost happen again and agin, how to use logstash to collect log event property ?
any reply will thankness
Logstash is all about reading logs from specific location and based on you interested information you can create index in elastic search or other output also possible.
Example of logstash conf
input {
file {
# PLEASE SET APPROPRIATE PATH WHERE LOG FILE AVAILABLE
#type => "java"
type => "json-log"
path => "d:/vox/logs/logs/vox.json"
start_position => "beginning"
codec => json
}
}
filter {
if [type] == "json-log" {
grok {
match => { "message" => "UserName:%{JAVALOGMESSAGE:UserName} -DL_JobID:%{JAVALOGMESSAGE:DL_JobID} -DL_EntityID:%{JAVALOGMESSAGE:DL_EntityID} -BatchesPerJob:%{JAVALOGMESSAGE:BatchesPerJob} -RecordsInInputFile:%{JAVALOGMESSAGE:RecordsInInputFile} -TimeTakenToProcess:%{JAVALOGMESSAGE:TimeTakenToProcess} -DocsUpdatedInSOLR:%{JAVALOGMESSAGE:DocsUpdatedInSOLR} -Failed:%{JAVALOGMESSAGE:Failed} -RecordsSavedInDSE:%{JAVALOGMESSAGE:RecordsSavedInDSE} -FileLoadStartTime:%{JAVALOGMESSAGE:FileLoadStartTime} -FileLoadEndTime:%{JAVALOGMESSAGE:FileLoadEndTime}" }
add_field => ["STATS_TYPE", "FILE_LOADED"]
}
}
}
filter {
mutate {
# here converting data type
convert => { "FileLoadStartTime" => "integer" }
convert => { "RecordsInInputFile" => "integer" }
}
}
output {
elasticsearch {
# PLEASE CONFIGURE ES IP AND PORT WHERE LOG DOCs HAS TO PUSH
document_type => "json-log"
hosts => ["localhost:9200"]
# action => "index"
# host => "localhost"
index => "locallogstashdx_new"
# workers => 1
}
stdout { codec => rubydebug }
#stdout { debug => true }
}

When I am trying to use logstash to read through a configuration file, I come up with map parsing error.
:response=>{"index"=>{"_index"=>"logstash-2016.06.07",
"_type"=>"txt", "_id"=>nil, "status"=>400,
"error"=>{"type"=>"mapper_parsing_exception", "r eason"=>"Failed to

unsupported parameters: [ignore_above : 1024]",
"caused_by"=>{"type"=>"mapper_parsing_exception", "reason"=>"Mapping
definition for [data] has unsupported para meters: [ignore_above :
1024]"}}}}, :level=>:warn}←[0m
I found that there is no problem is groking my logs but just do not know what is the matter of the error.
Here is my logstash.conf
input{
stdin{}
file{
type => "txt"
path => "C:\HA\accesslog\trial.log"
start_position => "beginning"
}
}
filter{
grok{
match => {"message" => ["%{IP:ClientAddr}%{SPACE}%{NOTSPACE:access_date}%{SPACE}%{TIME:access_time}%{SPACE}%{NOTSPACE:x-eap.wlsCustomLogField.VirtualHost}%{SPACE}%{WORD:cs-method}%{SPACE}%{PATH:cs-uri-stem}%{SPACE}%{PROG:x-eap.wlsCustomLogField.Protocol}%{SPACE}%{NUMBER:sc-status}%{SPACE}%{NUMBER:bytes}%{SPACE}%{NOTSPACE:x-eap.wlsCustomLogField.RequestedSessionId}%{SPACE}%{PROG:x-eap.wlsCustomLogField.Ecid}%{SPACE}%{NUMBER:x-eap.wlsCustomLogField.ThreadId}%{SPACE}%{NUMBER:x-eap.wlsCustomLogField.EndTs}%{SPACE}%{NUMBER:time-taken}"]}
}
if "_grokparsefailure" in [tags] {
drop { }
}
}
output{
elasticsearch {
hosts => ["localhost:9200"]
index => "logstash-%{+YYYY.MM.dd}"
template_overwrite => true
}
stdout { codec => rubydebug }
}
Please help. Thanks.
I turn out find out the sollution here: github.com/elastic/elasticsearch/issues/16283
Another problem is the created field for indexing is too long. Shortening the name can solve the issue.
I had been using the multline codec of logstash for my java exceptions. However, recently I wanted to capture more things and hence used another pattern. This causes my logstash not to read file even though I am using sincedb_path attribute.
My configurations file -
input {
file {
type => "pa"
path => "/home/jigar/POC/Docs/smalllogs/test"
codec => multiline {
pattern => "^%{DATESTAMP}"
negate => true
what => "previous"
}
start_position => "beginning"
sincedb_path => "/dev/null"
}
}
filter {
grok {
match => [ "message", "%{DATESTAMP:actualTimeStamp}%{SPACE}%{LOGLEVEL:level}%{SPACE}%{GREEDYDATA:identifier}%{SYSLOG5424SD:Id}%{SPACE}%{JAVACLASS:package}:%{INT:lineNum}%{SPACE}-%{SPACE}%{DATA:mydata}\n(\t)?%{GREEDYDATA:stack}" ]
}
}
output {
elasticsearch {
cluster => "smartdebugger"
protocol => "http"
host => "localhost"
}
stdout { codec =>rubydebug }
}
Can somebody please help me why logstash is not able to read the file.
I am shipping Glassfish 4 logfiles with Logstash to an ElasticSearch sink. How can I remove with Logstash the trailing newline from a message field?
My event looks like this:
{
"#timestamp" => "2013-11-21T13:29:33.081Z",
"message" => "[2013-11-21T13:29:32.577+0000] [glassfish 4.0] [INFO] [] [javax.resourceadapter.mqjmsra.lifecycle] [tid: _ThreadID=142 _ThreadName=Thread-43] [timeMillis: 1385040572577] [levelValue: 800] [[\n MQJMSRA_RA1101: GlassFish MQ JMS Resource Adapter stopped.]]\n",
"#version" => "1",
"tags" => ["multiline", "date_filtered"],
"host" => "myhost",
"path" => "../server.log"
}
A second solution is using the mutate filter of Logstash. It allows you to strip the value of a field.
filter {
# Remove leading and trailing whitspaces (including newline etc. etc.)
mutate {
strip => "message"
}
}
You have to use the multiline filter with the correct pattern, to tell logstash, that every line with precending whitespace belongs to the line before. Add this lines to your conf file.
filter{
...
multiline {
type => "gflogs"
pattern => "\[\#\|\d{4}"
negate => true
what => "previous"
}
...
}
You can also include grok plugin to handle timestamp and filter irregular lines from beeing indexed.
See complete stack with single logstash instance on same machine
input {
stdin {
type => "stdin-type"
}
file {
path => "/path/to/glassfish/logs/*.log"
type => "gflogs"
}
}
filter{
multiline {
type => "gflogs"
pattern => "\[\#\|\d{4}"
negate => true
what => "previous"
}
grok {
type => "gflogs"
pattern => "(?m)\[\#\|%{TIMESTAMP_ISO8601:timestamp}\|%{LOGLEVEL:loglevel}\|%{DATA:server_version}\|%{JAVACLASS:category}\|%{DATA:kv}\|%{DATA:message}\|\#\]"
named_captures_only => true
singles => true
}
date {
type => "gflogs"
match => [ "timestamp", "ISO8601" ]
}
kv {
type => "gflogs"
exclude_tags => "_grokparsefailure"
source => "kv"
field_split => ";"
value_split => "="
}
}
output {
stdout { codec => rubydebug }
elasticsearch { embedded => true }
}
This worked for me. Pleas look also this post on logstash-usergroup. I can also advice the great and up to date logstash book. Its also a good way to support the work of the logstash author.
Hope to see you on any JUG-Berlin Event!
