ES 2.4.1
Logstash 2.4.0
I am sending data to elasticsearch from local to create a index "pica".I used the below conf file.
input {
file {
path => "C:\Output\Receive.txt"
start_position => "beginning"
codec => json_lines
}
}
output {
elasticsearch {
hosts => "http://localhost:9200/"
index => "pica"
}
stdout{
codec => rubydebug
}
}
I couldn't see any output in either logstash prompt or in elasticsearch cluster.
When i seen the .sincedb file it has the following code:
612384816-350504-4325376 0 0 3804
May i know what's the problem here?
Thanks
I guess you're missing out the square brackets [] for the hosts value, since it's a type of array as per the doc. Hence it should look like:
elasticsearch {
hosts => ["localhost:9200"]
index => "pica"
}
OR :
hosts => ["127.0.0.1"] OR hosts => ["localhost"]

I am using the latest version of logstash(7.6.2). I tried uploading a sample data and was able to successfully upload it into the elasticsearch using logstash(enabled auto-reload) and was able to see the index in the Kibana interface.
But, when I make changes to the below config file, I was unable to see the updated data in the Kibana interface. I was trying to remove the mutate filter plugin and the logstash pipeline reloaded but the data in Kibana is not updated. Interestingly it didn't throw up any errors.
Sample.conf
input{
file{
path => "/usr/local/Cellar/sample.log"
start_position => "beginning"
}
}
filter{
grok{
match => ["message", "%{TIMESTAMP_ISO8601:timestamp_string}%{SPACE}%{GREEDYDATA:line}"]
}
date{
match => ["timestamp_string", "ISO8601"]
}
mutate{
remove_field => [message, timestamp_string]
}
}
output{
elasticsearch{
hosts => ["localhost:9200"]
index => "sample"
}
stdout{
codec => rubydebug
}
}
Any help here is appreciated. TIA
P.S. - I am new to ElasticSearch!
If you want to parse again a complete file, you need to :
delete sindedb files
OR only delete the corresponding line in sincedb file
Then, restart Logstash. Logstash will reparse the file.
For more info: https://www.elastic.co/guide/en/logstash/current/plugins-inputs-file.html#sincedb_path
I've tried to parse it using the json, json_lines and even the multiline input plugin, yet to no avail. The multiline works well on my local machine but doesn't seem to work on my s3 and ec2 instance.
How would I write the grok filter to parse this?
This is what my JSON file looks like
{
"sourceId":"94:54:93:3B:81:6F1",
"machineId":"c1VR21A0GoCBgU6EMJ78d3CL",
"columnsCSV":"timestamp,state,0001,0002,0003,0004",
"tenantId":"iugcp",
"valuesCSV":"1557920277890,1,98.66,0.07,0.1,0.17 ",
"timestamp":"2019-05-15T11:37:57.890Z"
}
This is my config -
input {
file{
codec => multiline
{
pattern => '^\{'
negate => true
what => previous
}
path => "/home/*myusername*/Desktop/data/*.json"
start_position => "beginning"
sincedb_path => "/dev/null"
}
}
filter {
mutate
{
replace => [ "message", "%{message}}" ]
gsub => [ 'message','\n','']
}
if [message] =~ /^{.*}$/
{
json { source => message }
}
}
//Output tag is correct, haven't included it here
The results I get is just the json file present in the "message" field.
What I wanted is for every json tag, there should be a separate field in the document.
I am pretty new to logstash.
In our application we are creating multiple indexes, from the below thread i could understand how to resolve that
How to create multiple indexes in logstash.conf file?
but that results in many duplicate lines in the conf file (for host, ssl, etc.). So i wanted to check if there is any better way of doing it?
output {
stdout {codec => rubydebug}
if [type] == "trial" {
elasticsearch {
hosts => "localhost:9200"
index => "trial_indexer"
}
} else {
elasticsearch {
hosts => "localhost:9200"
index => "movie_indexer"
}
}
Instead of above config, can i have something like below?
output {
stdout {codec => rubydebug}
elasticsearch {
hosts => "localhost:9200"
}
if [type] == "trial" {
elasticsearch {
index => "trial_indexer"
}
} else {
elasticsearch {
index => "movie_indexer"
}
}
What you are looking for is using Environment Variables in logstash pipeline. You define this once, and can use same redundant values like you said for HOST, SSL etc.
For more information Logstash Use Environmental Variables
e.g.,
output {
elasticsearch{
hosts => ${ES_HOST}
index => "%{type}-indexer"
}
}
Let me know, if that helps.
Logstash v2.4.1.
I'm sending JSON formatted logs to my Logstash server via UDP packet. The logs look something similar to this.
{
"key1":"value1",
"key2":"value2",
"msg":"2017-03-02 INFO [com.company.app] Hello world"
}
This is my output filter
output {
stdout {
codec => rubydebug
}
file {
path => "/var/log/trm/debug.log"
codec => line { format => "%{msg}" }
}
}
The rubydebug output codec shows the log like this
{
"message" => {\"key1\":\"value1\", "key2\":\"value2\", \"msg\":\"2017-03-02 INFO [com.company.app] Hello world\"
}
and the file output filter also shows the JSON log correctly, like this
{"key1":"value1", "key2":"value2", "msg":"2017-03-02 INFO [com.company.app] Hello world"}
When I use the JSON code in the input filter, I get _jsonparsefailures from Logstash on "some" logs, even though different online JSON parsers parse the JSON correctly, meaning my logs are in a valid JSON format.
input {
udp => {
port => 5555
codec => json
}
}
Therefore, I'm trying to use the json filter instead, like this
filter {
json => {
source => "message"
}
}
Using the json filter, how can I extract the "key1", "key2", and the "msg" fields in the "message?"
I tried this to no avail, that is, I don't see the "key1" field in my rubydebug output.
filter {
json => {
source => "message"
add_field => {
"key1" => "%{[message][key1]}"
}
}
}
I would suggest you to start with one of the two configuration below (I use the multiline codec to concatenate the input into a json, because otherwise logstash will read line by line, and one line of a json is not a valid json), then either filter the json, or use the json codec, and then output it to wherever it is needed. You will still have some configuration to do, but I believe it might help you to get started:
input{
file {
path => "/an/absolute/path/tt2.json" #It really has to be absolute!
start_position => beginning
sincedb_path => "/another/absolute/path" #Not mandatory, just for ease of testing
codec => multiline{
pattern => "\n"
what => "next"
}
}
}
filter{
json {
source => "multiline"
}
}
output {
file {
path => "data/log/trm/debug.log"
}
stdout{codec => json}
}
Second possibility:
input{
file {
path => "/an/absolute/path/tt2.json" #It really has to be absolute!
start_position => beginning
sincedb_path => "/another/absolute/path" #Not mandatory, just for ease of testing
codec => multiline{
pattern => "\n"
what => "next"
}
codec => json{}
}
}
output {
file {
path => "data/log/trm/debug.log"
}
stdout{codec => json}
}
Edit With the udp input I guess it should be (not tested):
input {
udp => {
port => 5555
codec => multiline{ #not tested this part
pattern => "^}"
what => "previous"
}
codec => json{}
}
}
Working on getting our ESET log files (json format) into elasticsearch. I'm shipping logs to our syslog server (syslog-ng), then to logstash, and elasticsearch. Everything is going as it should. My problem is in trying to process the logs in logstash...I cannot seem to separate the key/value pairs into separate fields.
Here's a sample log entry:
Jul 8 11:54:29 192.168.1.144 1 2016-07-08T15:55:09.629Z era.somecompany.local ERAServer 1755 Syslog {"event_type":"Threat_Event","ipv4":"192.168.1.118","source_uuid":"7ecab29a-7db3-4c79-96f5-3946de54cbbf","occured":"08-Jul-2016 15:54:54","severity":"Warning","threat_type":"trojan","threat_name":"HTML/Agent.V","scanner_id":"HTTP filter","scan_id":"virlog.dat","engine_version":"13773 (20160708)","object_type":"file","object_uri":"http://malware.wicar.org/data/java_jre17_exec.html","action_taken":"connection terminated","threat_handled":true,"need_restart":false,"username":"BATHSAVER\\sickes","processname":"C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe"}
Here is my logstash conf:
input {
udp {
type => "esetlog"
port => 5515
}
tcp {
type => "esetlog"
port => 5515
}
filter {
if [type] == "esetlog" {
grok {
match => { "message" => "%{DATA:timestamp}\ %{IPV4:clientip}\ <%{POSINT:num1}>%{POSINT:num2}\ %{DATA:syslogtimestamp}\ %{HOSTNAME}\ %{IPORHOST}\ %{POSINT:syslog_pid\ %{DATA:type}\ %{GREEDYDATA:msg}" }
}
kv {
source => "msg"
value_split => ":"
target => "kv"
}
}
}
output {
elasticsearch {
hosts => ['192.168.1.116:9200']
index => "eset-%{+YYY.MM.dd}"
}
}
When the data is displayed in kibana other than the data and time everything is lumped together in the "message" field only, with no separate key/value pairs.
I've been reading and searching for a week now. I've done similar things with other log files with no problems at all so not sure what I'm missing. Any help/suggestions is greatly appreciated.
Can you try belows configuration of logstash
grok {
match => {
"message" =>["%{CISCOTIMESTAMP:timestamp} %{IPV4:clientip} %{POSINT:num1} %{TIMESTAMP_ISO8601:syslogtimestamp} %{USERNAME:hostname} %{USERNAME:iporhost} %{NUMBER:syslog_pid} Syslog %{GREEDYDATA:msg}"]
}
}
json {
source => "msg"
}
It's working and tested in http://grokconstructor.appspot.com/do/match#result
Regards.
