I am using logstash for the first time and trying to setup a simple pipeline for just printing the nginx logs. Below is my config file
input {
file {
path => "/var/log/nginx/*access*"
}
}
output {
stdout { codec => rubydebug }
}
I have saved the file as /opt/logstash/nginx_simple.conf
And trying to execute the following command
sudo /opt/logstash/bin/logstash -f /opt/logstash/nginx_simple.conf
However the only output I can see is:
Logstash startup completed
Logstash shutdown completed
The file is not empty for sure. As per my understanding I should be seeing the output on my console. What am I doing wrong ?
Make sure that the character encoding of your logfile is UTF-8. If it is not, try to change it and restart the Logstash.
Please try this code as your Logstash configuration, in order to setup a simple pipeline for just printing the nginx logs.
input {
file {
path => "/var/log/nginx/*.log"
type => "nginx"
start_position => "beginning"
sincedb_path=> "/dev/null"
}
}
filter {
if [type] == "nginx" {
grok {
patterns_dir => "/home/krishna/Downloads/logstash-2.1.0/pattern"
match => {
"message" => "%{NGINX_LOGPATTERN:data}"
}
}
}
date {
match => [ "timestamp" , "dd/MMM/yyyy:HH:mm:ss Z" ]
}
}
output {
elasticsearch {
hosts => [ "127.0.0.1:9200" ]
}
stdout { codec => rubydebug }
}

Currently, I have a program that writes a json array into a json file. The json file is initially blank. I also have an instance of logstash running with the following config file.
input{
file{
path => "/Users/CP4/Downloads/gs-accessing-data-mysql-master/complete/example.json"
codec => "json"
start_position => "beginning"
ignore_older => 0
}
}
filter {
mutate {
gsub => [ "message","\[",""]
gsub => [ "message","\n",""]
gsub => [ "event","\},\{",","]
}
json { source => message }
}
output{
elasticsearch{
hosts => "localhost:9200"
index => "test123"
}
stdout { codec => rubydebug }
}
For some reason, logstash will only read the file once I go in and make some changes manually, rather than when my program writes json to it. What could be causing this? Is the way my config file is set up wrong? Thanks.
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 }
}

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 going to configure all log files present in location(D:\Logs folder)
log files are
1.Magna_Log4Net.log.20150623_bak
2.Magna_Log4Net.log.20150624_bak
3.Magna_Log4Net.log.20150625_bak
4.Magna_Log4Net.log.20150626_bak
logstash.conf file
input {
file {
path =["C:\Test\Logs\Magna_Log4Net.log.*_bak"]
start_position => "beginning"
}
}
filter {
grok { match => [ "message", "%{HTTPDATE:[#metadata][timestamp]}" ] }
date { match => [ "[#metadata][timestamp]", "dd/MMM/yyyy:HH:mm:ss Z" ] }
}
output {
elasticsearch { host => localhost}
stdout { codec => rubydebug }
}
I am not able to load all files into elastic search , I didn't understand the problem here. can any body help to to how to parse multiple files into logstash config files ???
I have just put up an ELK stack, but I am having trouble regarding the logstash configuration in /etc/logstash/conf.d I have two input sources being forwarded from one linux server, which has a logstash forwarder installed on it with the "files" looking like:
{
"paths": ["/var/log/syslog","/var/log/auth.log"],
"fields": { "type": "syslog" }
},
{
"paths": ["/var/log/osquery/osqueryd.results.log"],
"fields": { "type": "osquery_json" }
}
As you can see, one input is an osquery output (json formatted), and the other is syslog. My current config for logstash is osquery.conf:
input {
lumberjack {
port => 5003
ssl_certificate => "/etc/pki/tls/certs/logstash-forwarder.crt"
ssl_key => "/etc/pki/tls/private/logstash-forwarder.key"
codec => "json"
}
}
filter {
if [type] == "osquery_json" {
date {
match => [ "unixTime", "UNIX" ]
}
}
}
output {
elasticsearch { host => localhost }
stdout { codec => rubydebug }
}
Which works fine for the one input source, but I do not know how to add my other syslog input source to the same config, as the "codec" field is in the input -- I can't change it to syslog...
I am also planning on adding another input source in a windows log format that is not being forwarded by a logstash forwarder. Is there anyway to structure this differently?
It's probably better to just remove the codec from your input if you are going to be handling different codecs on the same input:
input {
lumberjack {
port => 5003
ssl_certificate => "/etc/pki/tls/certs/logstash-forwarder.crt"
ssl_key => "/etc/pki/tls/private/logstash-forwarder.key"
}
}
filter {
if [type] == "osquery_json" {
json {
source => "field_name_the_json_encoded_data_is_stored_in"
}
date {
match => [ "unixTime", "UNIX" ]
}
}
if [type] == "syslog" {
}
}
output {
elasticsearch { host => localhost }
stdout { codec => rubydebug }
}
Then you just need to decide what you want to do with your syslog messages.
I would suggest also splitting your config into multiple files. I tend to to use 01-filename.conf - 10-filename.conf for inputs, 11-29 as filters and anything above that for outputs. These files will be loaded in to logstash in the order they are printed in an ls.
