My simple config looks like this.
I have created a dummy folder in my home directory and created some log files in it.
My config file looks like this.
input{
file{
type => "dummylog"
path => [/home/rohit/dummy/*.log" ]
}
}
output{
elasticsearch{
embedded => true
}
}
Now after running logstash i am unable to see in any files in web ui of logstash. Those files have not fetched into elasticsearch. I am using an embedded elasticsearch so no need to run a separate process. Can anyone help me where i am committing mistake?
input {
file {
path => "/home/rohit/dummy/*.log"
type => "log"
}
}
filter {
if [type] == "log" {
grok {
pattern => "%{COMBINEDAPACHELOG}"
}
}
}
output {
elasticsearch { host => localhost } stdout { } }
}
to check for the pattern if correct run
$ bin/logstash agent -f
httpd-shipper.conf --configtest
Perhaps you should fix the syntax errors in your config and then see if there is a deeper problem.
You are missing a " in the line:
path => [/home/rohit/dummy/*.log" ]
If that doesn't solve the problem, it would be wise to confirm that the user that runs the logstash process, has read access to the log(s) it is trying to read.
Be very careful of the syntax. You missed "(quotes) in the path
input{
file{
type => "dummylog"
path => ["/home/rohit/dummy/*.log"]
}
}
output{
elasticsearch{
embedded => true
}
}
Also note that for this to work, elasticsearch has to be on the same host as logstash.
In addition to the opening quotation mark you must have forgotten about:
start_position => ... # string, one of ["beginning", "end"]
(optional), default: "end"
So, it should be:
input{
file{
type => "dummylog"
path => "/home/rohit/dummy/*.log"
start_position => "beginning"
}
}
output {
elasticsearch{
embedded => true
}
}

I am new to Logstash and ELK as a whole. I am trying to send my airflow logs to Logstash. I am confused on how to configure my configuration file, especially because I have several (nested) log files.
My airflow is deployed on an AWS EC2 instance and my logs directory is something like this: /home/ubuntu/run/logs/scheduler/
The scheduler directory has a couple of dated folders. Using one of the folders as an example:
/home/ubuntu/run/logs/scheduler/2022-08-31.
The dated folder has files such as
testing.py.log hello_world.py.log dag_file.py.log
Now, while configuring my /etc/logstash/conf.d/(based on the log path I shared above), how can I define my path to pick all the logs?
This is what my /etc/logstash/conf.d/apache-01.conf currently looks like, but I know the path isn't accurate:
input {
file {
path => "~/home/ubuntu/run/log/scheduler/"
start_position => "beginning"
codec -> "line"
}
}
filter {
grok {
match => { "path" => "" }
}
mutate {
add_field => {
"log_id" => "%{[dag_id]}-%{[task_id]}-%{[execution_date]}-%{[try_number]}"
}
}
}
output{
elasticsearch {
hosts => ["localhost:9200"]
}
}
The path parameter needs a absolute path.
To process all py.log files you can use this input
input {
file {
path => "/home/ubuntu/run/logs/scheduler/*/*py.log"
start_position => "beginning"
codec -> "line"
}
}
To process only the files hello_world.py.log and dag_file.py.log you can use an array for your path
input {
file {
path => ["/home/ubuntu/run/logs/scheduler/*/hello_world.py.log", "/home/ubuntu/run/logs/scheduler/*/dag_file.py.log"]
start_position => "beginning"
codec -> "line"
}
}
I am trying to collect logs from multiple directories through Logstash and send them to Elasticsearch.
This is my configuration:
input{
file {
path => ["/XXX/XXX/results/**/log_file.txt"]
start_position => "beginning"
sincedb_path => "/dev/null"
}
}
filter {
grok {
pattern_definitions => { "THREAD_NAME" => "%{WORD}?%{NUMBER}?" }
match => { "message" => "%{SPACE}?%{TIMESTAMP_ISO8601:asctime}?%{SPACE}?\|%{SPACE}?%{THREAD_NAME:thread_name}"}
}
}
output{
elasticsearch {
hosts => ["x.x.x.x:9200"]
}
stdout { codec => rubydebug }
}
The file path is a relative path.
The logs are placed inside different directories placed inside the results directory:
results/dir/log_file.txt.
I have tried this configuration with stdin and logs appeared inside Kibana, but Logstash doesn't pick up the logs in the directories. Please advise.
I have configured the logstash configuration as below to read the logs generated by spring boot to push into elastic search, but index is not creating even though logstash started successfully,
Conf file:
input {
file {
path => "C:\workspace\app\logback\applogs.log"
codec => "json"
type => "logback"
}
}
output {
if [type]=="logback" {
elasticsearch {
hosts => [ "localhost:9200" ]
index => "logback-test"
}
}
}
Thanks in Advance!
You should change the character from "\" to "/" in path for windows, specially windows 10.
So, you can rewrite the path like the following:
file {
path => "C:/workspace/app/logback/applogs.log" // not like "C:\workspace\app\logback\applogs.log"
codec => "json"
type => "logback"
}
I am following an online tutorial and have been provided with a cars.csv file and the following Logstash config file. My logstash is running perfectly well and is indexing the CSV as we speak.
The question is, I have another log file (entirely different data) which I need to parse and index into a different index.
How do I add this configuration without restarting logstash?
If above isn't possible and I edit the config file then restart logstash - it won't reindex the entire cars file will it?
If I do 2. How do I format the config for multiple styles of log file.
eg. my new log file looks like this:
01-01-2017 ORDER FAILED: £12.11 Somewhere : Fraud
Existing Config File:
input {
file {
path => "/opt/cars.csv"
start_position => "beginning"
sincedb_path => "/dev/null"
}
}
filter {
csv {
separator => ","
columns =>
[
"maker",
"model",
"mileage",
"manufacture_year",
"engine_displacement",
"engine_power",
"body_type",
"color_slug",
"stk_year",
"transmission",
"door_count",
"seat_count",
"fuel_type",
"date_last_seen",
"date_created",
"price_eur"
]
}
mutate {
convert => ["mileage", "integer"]
}
mutate {
convert => ["price_eur", "float"]
}
mutate {
convert => ["engine_power", "integer"]
}
mutate {
convert => ["door_count", "integer"]
}
mutate {
convert => ["seat_count", "integer"]
}
}
output {
elasticsearch {
hosts => "localhost"
index => "cars"
document_type => "sold_cars"
}
stdout {}
}
Config file for orders.log
input {
file {
path => "/opt/logs/orders.log"
start_position => "beginning"
sincedb_path => "/dev/null"
}
}
filter {
grok {
match => { "message" => "(?<date>[0-9-]+) (?<order_status>ORDER [a-zA-Z]+): (?<order_amount>£[0-9.]+) (?<order_location>[a-zA-Z]+)( : (?<order_failure_reason>[A-Za-z ]+))?"}
}
mutate {
convert => ["order_amount", "float"]
}
}
output {
elasticsearch {
hosts => "localhost"
index => "sales"
document_type => "order"
}
stdout {}
}
Disclaimer: I'm a complete newbie. Second day using ELK.
For point 1, either in your logstash.yml file, you can set
config.reload.automatic:true
Or, while executing logstash with conf file, run it like:
bin/logstash -f conf-file-name.conf --config.reload.automatic
After doing either of these settings, you can start your logstash and from now on any change you make in conf file will be reflected back.
2. If above isn't possible and I edit the config file then restart logstash - it won't reindex the entire cars file will it?
If you use sincedb_path => "/dev/null", Logstash won't remember where is has stopped reading a document and will reindex it at each restart. You'll have to remove this line if you wish for Logstash to remember (see here).
3.How do I format the config for multiple styles of log file.
To support multiple style of log files, you can put tags on the file inputs (see https://www.elastic.co/guide/en/logstash/5.5/plugins-inputs-file.html#plugins-inputs-file-tags) and then use conditionals (see https://www.elastic.co/guide/en/logstash/5.5/event-dependent-configuration.html#conditionals) in your file config.
Like this:
file {
path => "/opt/cars.csv"
start_position => "beginning"
sincedb_path => "/dev/null"
tags => [ "csv" ]
}
file {
path => "/opt/logs/orders.log"
start_position => "beginning"
sincedb_path => "/dev/null"
tags => [] "log" ]
}
if csv in [tags] {
...
} else if log in [tags] {
...
}
I want to send logs from different location to elasticsearch using logstash conf file.
input {
file
{
path => "C:/Users/611166850/Desktop/logstash-5.0.2/logstash-5.0.2/logs/logs/ce.log"
type => "CE"
start_position => "beginning"
}
file
{
path => "C:/Users/611166850/Desktop/logstash-5.0.2/logstash-5.0.2/logs/logs/spovp.log"
type => "SP"
start_position => "beginning"
}
file
{
path => "C:/Users/611166850/Desktop/logstash-5.0.2/logstash-5.0.2/logs/logs/ovpportal_log"
type => "OVP"
start_position => "beginning"
}
}
output {
elasticsearch {
action => "index"
hosts => "localhost:9200"
index => "multiple"
codec => json
workers => 1
}
}
This is the config file I use, but Kibana is not recognising this index. Can someone help with this
Thanks in advance ,Rashmi
Check logstash's log file for errors.(maybe you'r config file is not correct)
Also search ES directly for preferred index, maybe problem is not Kibana, and you don't have any index with this name.
try starting logstash in debug mode to see if there are any logs in it.
you can also try to get the logstash out put to a file on local system rather than directly sending it to the elasticsearch. uncomment block as per your requirement
# block-1
# if "_grokparsefailure" not in [tags] {
# stdout {
# codec => rubydebug { metadata => true }
# }
# }
# block-2
# if "_grokparsefailure" not in [tags] {
# file {
# path => "/tmp/out-try1.logstash"
# }
# }
so by any of these methods you can get the output to console or to a file. comment _grokparsefailure part in case you don't see any output in file.
Note: in kibana default indices have #timestamp in their fields so check
1. if kibana is able to recognize the index if you unckeck the checkbox on page where you create new index
2. if your logs are properly parsed. if not you need to work out with grok filters with pattern matching your logs or create grok filters
all elasticsearch indices are visible on http://elasticsearch-ip:9200/_cat/indices?v (your elasticsearch ip) so try that too. share what you find
