I am new in Elasticsearch,Kibana et Logstash. I am trying to load a json file like this one:
{"timestamp":"2014-05-19T00:00:00.430Z","memoryUsage":42.0,"totalMemory":85.74,"usedMemory":78.77,"cpuUsage":26.99,"monitoringType":"jvmHealth"}
{"timestamp":"2014-05-19T00:09:10.431Z","memoryUsage":43.0,"totalMemory":85.74,"usedMemory":78.77,"cpuUsage":26.99,"monitoringType":"jvmHealth"}
{"timestamp":"2014-05-19T00:09:10.441Z","transactionTime":1,"nbAddedObjects":0,"nbRemovedObjects":0,"monitoringType":"transactions"}
{"timestamp":"2014-05-19T00:09:10.513Z","transactionTime":6,"nbAddedObjects":4,"nbRemovedObjects":0,"monitoringType":"transactions"}
No index is created and I just get this message :
Using milestone 2 input plugin 'file'. This plugin should be stable,
but if you see strange behavior, please let us know! For more
information on plugin milestones, see
http://logstash.net/docs/1.4.1/plugin-milestones {:level=>:warn}
What can be the problem? I can use directly bulk but I must go with logstash.
Do you have any suggested code that can help?
EDIT (to move the config from a comment into the question):
input {
file {
path => "/home/ndoye/Elasticsearch/great_log.json"
type => json
codec => json
}
}
filter {
date {
match => ["timestamp","yyyy-MM-dd HH:mm:ss.SSS"]
}
}
output {
stdout{
#codec => rubydebug
}
elasticsearch {
embedded => true
}
}

I am using LogStash which accepts data from a log file, which has different types of logs.
The first row represents a custom log, whereas the second row represents a log in JSON format.
Now, I want to write a filter which will parse the logs on the basis of content and finally direct all the JSON format logs to a file called jsonformat.log and the other logs into a seperate file.
You can leverage the json filter and check if it failed or not to decide where to send the event.
input {
file {
path => "/Users/mysystem/Desktop/abc.log"
start_position => beginning
ignore_older => 0
}
}
filter {
json {
source => "message"
}
}
output {
# this condition will be true if the log line is not valid JSON
if "_jsonparsefailure" in [tags] {
file {
path => "/Users/mysystem/Desktop/nonjson.log"
}
}
# this condition will be true if the log line is valid JSON
else {
file {
path => "/Users/mysystem/Desktop/jsonformat.log"
}
}
}
I am new to ES. Trying to send json events to ES with https://github.com/awslabs/logstash-output-amazon_es
However, when I give below configuration it does not recognize any events?
input {
file {
path => "C:/Program Files/logstash-2.3.1/transactions.log"
start_position => beginning
codec => "json_lines"
}
}
filter {
json {
source => "message"
}
}
output {
amazon_es {
hosts => ["endpoint"]
region => "us-east-1"
codec => json
index => "production-logs-%{+YYYY.MM.dd}"
}
}
I am running it in debug mode but there is nothing in the log
Also do I need to create the index before I start sending the events from Logstash?
The below config works somehow, however it does not recognize any json fields
input {
file {
path => "C:/Program Files/logstash-2.3.1/transactions.log"
start_position => beginning
}
}
output {
amazon_es {
hosts => ["Endpoint"]
region => "us-east-1"
index => "production-logs-%{+YYYY.MM.dd}"
}
}
There may be several things at play here, including:
Logstash thinks your file has already been processed. start_position is only for files that haven't been seen before. If you're testing, set sincedb_path to /dev/null, or manually manage your registry files.
You're having mapping problems. Elasticsearch will drop documents when the field mapping isn't correct (trying to insert a string into a numeric field, etc). This should be shown in the elasticsearch logs, if you can get to them on AWS.
debug is very verbose. If you're really getting nothing, then you're not receiving any input. See the first bullet item.
adding a stdout{} output is a good idea until you get things working. This will show you what logstash is sending to elasticsearch.
I'm not sure if this is a follow-up or separate question to this one. There is some piece about LogStash that is not clicking. For that, I apologize for a related question. Still, I'm going out of my mind here.
I have an app that writes logs to a file. Each log entry is a JSON object. An example of my .json file looks like the following:
{
"logger":"com.myApp.ClassName",
"timestamp":"1456976539634",
"level":"ERROR",
"thread":"pool-3-thread-19",
"message":"Danger. There was an error",
"throwable":"java.Exception"
},
{
"logger":"com.myApp.ClassName",
"timestamp":"1456976539649",
"level":"ERROR",
"thread":"pool-3-thread-16",
"message":"I cannot go on",
"throwable":"java.Exception"
}
This format is what's created from Log4J2's JsonLayout. I'm trying my damnedest to get the log entries into LogStash. In an attempt to do this, I've created the following LogStash configuration file:
input {
file {
type => "log4j"
path => "/logs/mylogs.log"
}
}
output {
file {
path => "/logs/out.log"
}
}
When I open /logs/out.log, I see a mess. There's JSON. However, I do not see the "level" property or "thread" property that Log4J generates. An example of a record can be seen here:
{"message":"Danger. There was an error","#version":"1","#timestamp":"2014-04-08T17:20:10.035Z","type":"log4j","host":"ip-myAddress","path":"/logs/mylogs.log"}
Sometimes I even get parse errors. I need my properties to still be properties. I do not want them crammed into the message portion or the output. I have a hunch this has something to do with Codecs. Yet, I'm not sure. I'm not sure if I should change the codec on the logstash input configuration. Or, if I should change the input on the output configuration. I would sincerely appreciate any help as I'm getting desperate at this point.
Can you change your log format?
After I change your log format to
{ "logger":"com.myApp.ClassName", "timestamp":"1456976539634", "level":"ERROR", "thread":"pool-3-thread-19", "message":"Danger. There was an error", "throwable":"java.Exception" }
{ "logger":"com.myApp.ClassName", "timestamp":"1456976539649", "level":"ERROR", "thread":"pool-3-thread-16", "message":"I cannot go on", "throwable":"java.Exception" }
One json log per one line and without the "," at the end of the log, I can use the configuration below to parse the json message to correspond field.
input {
file {
type => "log4j"
path => "/logs/mylogs.log"
codec => json
}
}
input {
file {
codec => json_lines { charset => "UTF-8" }
...
}
}
should do the trick
Use Logstash's log4j input.
http://logstash.net/docs/1.4.2/inputs/log4j
Should look something like this:
input {
log4j {
port => xxxx
}
}
This worked for me, good luck!
I think #Ben Lim was right, your Logstash config is fine, just need to properly format input JSON to have each log event in a single line. This is very simple with Log4J2's JsonLayout, just set eventEol=true and compact=true. (reference)
I'm going out of my mind here. I have an app that writes logs to a file. Each log entry is a JSON object. An example of my .json file looks like the following:
{"Property 1":"value A","Property 2":"value B"}
{"Property 1":"value x","Property 2":"value y"}
I'm trying desperately to get the log entries into LogStash. In an attempt to do this, I've created the following LogStash configuration file:
input {
file {
type => "json"
path => "/logs/mylogs.log"
codec => "json"
}
}
output {
file {
path => "/logs/out.log"
}
}
Right now, I'm manually adding records to mylogs.log to try and get it working. However, they appear oddly in the stdout. When I look open out.log, I see something like the following:
{"message":"\"Property 1\":\"value A\", \"Property 2\":\"value B\"}","#version":"1","#timestamp":"2014-04-08T15:33:07.519Z","type":"json","host":"ip-[myAddress]","path":"/logs/mylogs.log"}
Because of this, if I send the message to ElasticSearch, I don't get the fields. Instead I get a jumbled mess. I need my properties to still be properties. I do not want them crammed into the message portion or the output. I have a hunch this has something to do with Codecs. Yet, I'm not sure. I'm not sure if I should change the codec on the logstash input configuration. Or, if I should change the input on the output configuration.
Try removing the json codec and adding a json filter:
input {
file {
type => "json"
path => "/logs/mylogs.log"
}
}
filter{
json{
source => "message"
}
}
output {
file {
path => "/logs/out.log"
}
}
You do not need the json codec because you do not want decode the source JSON but you want filter the input to get the JSON data in the #message field only.
By default tcp put everything to message field if json codec not specified.
An workaround to _jsonparsefailure of the message field after we specify the json codec also can be rectified by doing the following:
input {
tcp {
port => '9563'
}
}
filter{
json{
source => "message"
target => "myroot"
}
json{
source => "myroot"
}
}
output {
elasticsearch {
hosts => [ "localhost:9200" ]
}
}
It will parse message field to proper json string to field myroot
and then myroot is parsed to yield the json.
We can remove the redundant field like message as
filter {
json {
source => "message"
remove_field => ["message"]
}
}
Try with this one:
filter {
json {
source => "message"
target => "jsoncontent" # with multiple layers structure
}
}
I am trying to use logstash for analyzing a file containing JSON objects as follows:
{"Query":{"project_id":"a7565b911f324a9199a91854ea18de7e","timestamp":1392076800,"tx_id":"2e20a255448742cebdd2ccf5c207cd4e","token":"3F23A788D06DD5FE9745D140C264C2A4D7A8C0E6acf4a4e01ba39c66c7c9cbd6a123588b22dc3a24"}}
{"Response":{"result_code":"Success","project_id":"a7565b911f324a9199a91854ea18de7e","timestamp":1392076801,"http_status_code":200,"tx_id":"2e20a255448742cebdd2ccf5c207cd4e","token":"3F23A788D06DD5FE9745D140C264C2A4D7A8C0E6acf4a4e01ba39c66c7c9cbd6a123588b22dc3a24","targets":[]}}
{"Query":{"project_id":"a7565b911f324a9199a91854ea18de7e","timestamp":1392076801,"tx_id":"f7f68c7fb14f4959a1db1a206c88a5b7","token":"3F23A788D06DD5FE9745D140C264C2A4D7A8C0E6acf4a4e01ba39c66c7c9cbd6a123588b22dc3a24"}}
Ideally i'd expect Logstash to understand the JSON.
I used the following config:
input {
file {
type => "recolog"
format => json_event
# Wildcards work, here :)
path => [ "/root/isaac/DailyLog/reco.log" ]
}
}
output {
stdout { debug => true }
elasticsearch { embedded => true }
}
I built this file based on this Apache recipe
When running logstash with debug = true, it reads the objects like this:
How could i see stats in the kibana GUI based on my JSON file, for example number of Query objects and even queries based on timestamp.
For now it looks like it understand a very basic version of the data not the structure of it.
Thx in advance
I found out that logstash will automatically detect JSON byt using the codec field within the file input as follows:
input {
stdin {
type => "stdin-type"
}
file {
type => "prodlog"
# Wildcards work, here :)
path => [ "/root/isaac/Mylogs/testlog.log"]
codec => json
}
}
output {
stdout { debug => true }
elasticsearch { embedded => true }
}
Then Kibana showed the fields of the JSON perfectly.
