I am trying to load a txt file into Elasticsearch with Logstash. The txt file is a simple text which consists of 3 lines, and it looks like this:
text file
My conf file looks like this:
input {
file {
path => "C:/Users/dinar/Desktop/myfolder/mytest.txt"
start_position => "beginning"
sincedb_path => "NULL"
}
}
output {
elasticsearch {
hosts => "localhost:9200"
index => "mydemo"
document_type => "intro"
}
stdout {}
}
After I run this and I go to Kibana, I can see the index being created. However, the only messages I see are the first two lines, and the last line is not displayed. This is what I see:
Kibana page
Does anybody know why the last line is not being imported and how I can fix this?
Thank you all for your help.
Based on the screenshot, my assumption is that you are editing the file manually. In that case please verify, there is a newline after the last log entry: Just hit Enter & Save.

I'm trying to upload some csv files in elastic search. I don't want to mess it up , so I'm writing for some guidance. Can someone help with a video/tutorial/documentation , of how to index a document in elastic search? I've read the official documentation, but I feel a bit lost as a begginer. It will be fine If you'll recommend me a video tutorial , or you'll describe me some steps. Hope you are all doing well! Thank you for your time !
The best way is to use Logstash, which is official and very fast pipeline for elastic ,you can download it from here
First of all create a configuration file as below example and save it as logstashExample.conf in bin directory of logstash.
With assuming that elastic server and kibana console are up and running , run the configuration file with this command "./logstash -f logstashExample.conf" .
I've also added a suitable example of related configuration file for Logstash , please change the index name in output and your file path in input with respect of your need, you can also disable filtering by removing csv components in below example.
input {
file {
path => "/home/timo/bitcoin-data/*.csv"
start_position => "beginning"
sincedb_path => "/dev/null"
}
}
filter {
csv {
separator => ","
#Date,Open,High,Low,Close,Volume (BTC),Volume (Currency),Weighted Price
columns => ["Date","Open","High","Low","Close","Volume (BTC)", "Volume (Currency)" ,"Weighted Price"]
}
}
output {
elasticsearch {
hosts => "http://localhost:9200"
index => "bitcoin-prices"
}
stdout {}
}
Elasticsearch has become extremely slow when receiving input from Logstash, particularly when using file input. I have had to wait for 10+ minutes to get results. Oddly enough, standard input is mapped very quickly, which leads me to believe that my config file may be too complex, but it really isn't.
My config file uses file input, my filter is grok with 4 fields, and my output is to Elasticsearch. The file I am inputting is a .txt with 5 lines in it.
Any suggestions? Elasticsearch and Logstash newbie here.
input {
file {
type => "type"
path => "insert_path"
start_position = > "beginning'
}
}
filter {
grok { match => {"message" => "%{IP:client} %{WORD:primary} %{WORD:secondary} %{NUMBER:speed}" }
}
output {
elasticsearch {
hosts => ["localhost:9200"]
}
}
Thought: Is it a sincedb_path issue? I often try to reparse files without changing the filename.
I have a 2 separate IIS log files (advanced and simple)
They need to be joined, because the advanced log is missing information that the simple one has written, but they have the same timestamp.
input { file {
path => "C:/Logs/*.log"
start_position => "beginning"}
}
filter {
grok {
break_on_match => "true"
match => ["message", '%{TIMESTAMP_ISO8601:log_timestamp} \"%{DATA:s_computername}\"']
match => ["message", "%{TIMESTAMP_ISO8601:log_timestamp} %{NOTSPACE:uriQuery} "]
}
output {
elasticsearch {
hosts => "localhost:9200"
}
}
}
simplified version. I want elasticsearch to have a entry containing log_timestamp, s_computername, and uriQuery.
Using the multiline codec, it is possible to merge them if the lines were next to each other. As they're in separate files, I have not yet found a way to do this. Is it possible to merge the two using the same timestamp as a unique identifier?
I'm very new to the elasticsearch-kibana-logstash and can't seem to find solution for this one.
I'm trying to create index that I will see in kibana without having to use the POST command in Dev Tools section.
I have set test.conf-
input {
file {
path => "/home/user/logs/server.log"
type => "test-type"
start_position => "beginning"
}
}
output {
elasticsearch {
hosts => ["localhost:9200"]
index => "new-index"
}
}
and then
bin/logstash -f test.conf from logstash directory
what i get is that I can't find the new-index in kibana (index patterns section), when I use elasticsearch - http://localhost:9200/new-index/ it presents an error and when I go to http://localhost:9600/ (the port it's showing) it doesn't seem to have any errors
Thanks a lot for the help!!
It's obvious that you won't be able to find the index which you've created using logstash in Kibana, unless you're manually creating it there within the Managemen section of Kibana.
Make sure, that you have the same name of the indice which you created using logstash. Have a look at the doc, which conveys:
When you define an index pattern, indices that match that pattern must
exist in Elasticsearch. Those indices must contain data.
which pretty much says that the indice should exist for you to create the index in Kibana. Hope it helps!
I have actually succeeded to create index even without first creating it in Kibana
I used the following config file -
input {
file {
path => "/home/hadar/tmp/logs/server.log"
type => "test-type"
id => "NEWTRY"
start_position => "beginning"
}
}
filter {
grok {
match => { "message" => "%{YEAR:year}-%{MONTHNUM:month}-%{MONTHDAY:day} %{HOUR:hour}:%{MINUTE:minute}:%{SECOND:second} - %{LOGLEVEL:level} - %{WORD:scriptName}.%{WORD:scriptEND} - " }
}
}
output {
elasticsearch {
hosts => ["localhost:9200"]
index => "new-index"
codec => line { format => "%{year}-%{month}-%{day} %{hour}:%{minute}:%{second} - %{level} - %{scriptName}.%{scriptEND} - \"%{message}\"" }
}
}
I made sure that the index wasn't already in Kibana (I tried with other indexes names too just to be sure...) and eventually I did see the index with the log's info in both Kibana (I added it in the index pattern section) and Elasticsearch when I went to http://localhost:9200/new-index
The only thing I should have done was to erase the .sincedb_XXX files which are created under data/plugins/inputs/file/ after every Logstash run
OR
the other solution (for tests environment only) is to add sincedb_path=>"/dev/null" to the input file plugin which indicates to not create the .sincedb_XXX file
You can create directly index in elastic search using https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-create-index.html
and these indices can be used in Kibana.
I have tab separated data which I want to input into logstash. Here is my configuration file:
input {
file {
path => "/*.csv"
type => "testSet"
start_position => "beginning"
}
}
filter {
csv {
separator => "\t"
}
}
output {
stdout {
codec => rubydebug
}
}
It simply looks for all .csv files and separates them using tabs. For an input like this:
col1 col2
data1 data2
logstash output is (for the two rows):
column1 => "col1\tcol2"
column1 => "data1\tdata2"
Obviously it is not correctly parsing it. I saw that this issue was brought up a while ago here but there was no solution. Does anyone know if this problem has been resolved or maybe there's another way to do it? Thanks!
Instead of using "\t" as the seperator, input an actual tab.
like this:
filter {
csv {
separator => " "
}
}
https://www.elastic.co/guide/en/logstash/6.2/plugins-filters-csv.html#plugins-filters-csv-separator
Define the column separator value. If this is not specified, the default is a comma ,. If you want to define a tabulation as a separator, you need to set the value to the actual tab character and not \t.
