I am trying to read a son file data and visualize it in Kibana.The following is my stack.
read json file --> logstash --> elastic search -> Kibana (UI)
I tried the following simple configuration and it works fine till it reaches kibana.
input { stdin { } }
output {
elasticsearch { host => localhost }
}
When I tried to read the data from file and push it to elastic.I am not able to see the output .
input {
stdin {
type => "stdin-type"
}
file {
type => "jsonlog"
# Wildcards work, here :)
path => [ "/Users/path/logstash-1.5.0/sample.json" ]
codec => json
}
}
output {
stdout { }
elasticsearch { embedded => true }
}
Output : It says "logstash started".But I could not see the results in elastic nor the stdout
Jun 10, 2015 4:32:10 PM org.elasticsearch.node.internal.InternalNode start
INFO: [logstash-MacBook-Pro.local-12298-9782] started
Logstash startup completed
Software Version :
Logstash -> 1.5.0
Elasticsearch -> 1.5.2
Thanks in advance !

I have a problem about running defined configuration file in logstash though its command.
Here is my conf file shown below.
input {
file {
type => "userslog"
path => "C:\Users\aaa\Downloads\logstash-8.1.0\users-ms.log"
}
file {
type => "albumslog"
path => "C:\Users\aaa\Downloads\logstash-8.1.0\albums-ms.log"
}
}
output {
if[type]=="userslog"{
elasticsearch {
hosts => ["localhost:9200"]
index => "userslog-%{+YYYY.MM.dd}"
}
} else if[type]=="albumslog"{
elasticsearch {
hosts => ["localhost:9200"]
index => "albumslog-%{+YYYY.MM.dd}"
}
}
stdout {codec => rubydebug}
}
Here is the result shown below.
C:\Users\aaa\Desktop\logstash-8.1.0\bin>logstash logstash-simple.conf
"Using bundled JDK: ."
OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.
[FATAL] 2022-03-17 12:03:32.267 [main] Logstash - Logstash stopped processing because of an error: (NameError) missing class name (`org.apache.http.─▒mpl.client.StandardHttpRequestRetryHandler')
org.jruby.exceptions.NameError: (NameError) missing class name (`org.apache.http.─▒mpl.client.StandardHttpRequestRetryHandler')
When changed 'Java::OrgApacheHttpImplClient::StandardHttpRequestRetryHandler' to 'Java::OrgApacheHttp.impl.client::StandardHttpRequestRetryHandler', it didn't work.
How can I fix it?
I´m trying to setup an environment for grok debugging and made this with a docker.
Everything works fine, until logstash tries to resolve a custom pattern.
Here is my environment
I start the docker with
docker run -it --name logstash_debug -v
/home/cloud/docker-elk/logstash/config/logstash.yml:/usr/share/logstash/config/logstash.yml
-v /home/cloud/docker-elk/logstash/pipeline/:/usr/share/logstash/pipeline/
-v /home/cloud/docker-elk/logstash/patterns/:/usr/share/logstash/patterns
docker.elastic.co/logstash/logstash:7.2.0
As I said, logstash starts up, loads the pipeline (debug.conf)
input { stdin {} }
filter {
grok {
patterns_dir => ["/usr/share/logstash/patterns"]
match => ["message", "%{YEAR1} \[%{LOGLEVEL:loglvl}\] %{GREEDYDATA:message}"]
}
date {
match => ["customer_time", "${YEAR1}"]
target => "#timestamp"
}
}
output { stdout { codec => rubydebug } }
and gives me this error:
Cannot evaluate ${YEAR1}. Replacement variable YEAR1 is not
defined in a Logstash secret store or as an Environment entry and
there is no default value given.
the patterns_dir contains a file "dateformats" which contains (stripped it down to a minimum)
YEAR1 %{YEAR}
the logstash debug output gives me this:
[DEBUG][logstash.filters.grok ] config
LogStash::Filters::Grok/#patterns_dir =
["/usr/share/logstash/patterns"]
[DEBUG][logstash.filters.grok ] config
LogStash::Filters::Grok/#match = {"message"=>"%{YEAR1}
\[%{LOGLEVEL:loglvl}\] %{GREEDYDATA:message}"}
.....
[DEBUG][logstash.filters.grok ] config
LogStash::Filters::Grok/#patterns_files_glob = "*"
Normally logstash should be able to grab this file (I even started the docker with --user 0 to be sure that I have no permission problem) but it somehow can´t.
Anyone can me give a hint to what´s going on ?
Thanks and cheers,

I am trying to configure my Logstash to read from a specified log file. When I configure it to read from stdin it works as expected, my input results in a message from Logstash and displays in my Kibana UI.
$ cat /tmp/logstash-stdin.conf
input {
stdin {}
}
output {
elasticsearch { hosts => ["localhost:9200"] }
stdout { codec => rubydebug }
}
$./logstash -f /tmp/logstash-stdin.conf
WARNING: Could not find logstash.yml which is typically located in $LS_HOME/config or /etc/logstash. You can specify the path using --path.settings. Continuing using the defaults
Could not find log4j2 configuration at path //usr/share/logstash/config/log4j2.properties. Using default config which logs errors to the console
The stdin plugin is now waiting for input:
hellloooo
{
"#version" => "1",
"host" => "myhost.com",
"#timestamp" => 2017-11-17T16:05:41.595Z,
"message" => "hellloooo"
}
However, when I run Logstash with a file input I get no indication that the file is loaded into Logstash, and it does not show in Kibana.
$ cat /tmp/logstash-simple.conf
input {
file {
path => "/tmp/test_log.txt"
type => "syslog"
}
}
output {
elasticsearch { hosts => ["localhost:9200"] }
stdout { codec => rubydebug }
}
$ ./logstash -f /tmp/logstash-simple.conf
WARNING: Could not find logstash.yml which is typically located in $LS_HOME/config or /etc/logstash. You can specify the path using --path.settings. Continuing using the defaults

Any suggestions of how I can troubleshoot why my Logstash is not ingesting the configured file?
By default the file input plugin starts reading at the end of the file, so only lines added after Logstash starts will be processed. To read all existing lines upon startup add the option "start_position" => "beginning" to the configuration, as explained in documentation.
I have created a simple json like below
[
{
"Name": "vishnu",
"ID": 1
},
{
"Name": "vishnu",
"ID": 1
}
]
I am holding this values in file named simple.txt . Then i used file beat to listen the file and send the new updates to port 5043,on other side i started the log-stash service which listen to this port in order to parse and pass the json to elastic search.
log-stash is not processing the json values,it hangs in the middle.
logstash
input {
beats {
port => 5043
host => "0.0.0.0"
client_inactivity_timeout => 3600
}
}
filter {
json {
source => "message"
}
}
output {
stdout { codec => rubydebug }
}
filebeat config:
filebeat.prospectors:
- input_type: log
paths:
- filepath
output.logstash:
hosts: ["localhost:5043"]
Logstash output

Every time when i am running log-stash using command
logstash -f logstash.conf
And since there is no processing of json i am stopping that service by pressing ctrl + c .
Please help me in finding the solution.Thanks in advance.
finally i got ended up with config like this.It works for me.
input
{
file
{
codec => multiline
{
pattern => '^\{'
negate => true
what => previous
}
path => "D:\elasticdb\logstash-tutorial.log\Test.txt"
start_position => "beginning"
sincedb_path => "D:\elasticdb\logstash-tutorial.log\null"
exclude => "*.gz"
}
}
filter {
json {
source => "message"
remove_field => ["path","#timestamp","#version","host","message"]
}
}
output {
elasticsearch { hosts => ["localhost"]
index => "logs"
"document_type" => "json_from_logstash_attempt3"
}
stdout{}
}
Json format:
{"name":"sachin","ID":"1","TS":1351146569}
{"name":"sachin","ID":"1","TS":1351146569}
{"name":"sachin","ID":"1","TS":1351146569}
Need your help in custom log parsing through logstash
Here is the log format that I am trying to parse through logstash
2015-11-01 07:55:18,952 [abc.xyz.com] - /Enter, G, _null, 2702, 2, 2, 2, 2, PageTotal_1449647718950_1449647718952_2_App_e9c00521-eeec-4d47-bf5b-b842ec14a4ff_178.255.153.2___, , , NEW,
And my logstash conf file looks like below
input {
file {
path => [ "/tmp/access.log" ]
}
}
filter{
grok {
match => { "message" => "%{TIMESTAMP_ISO8601:timestamp} %{GREEDYDATA:message}" }
}
date {
match => ["timestamp","yyyy-MM-dd HH:mm:ss,SSSS"]
}
}
For some reason running the logstash command passing the conf file doesnt parse the logs, not sure whats wrong with the config. Any help would be highly appreciated.
bin/logstash -f conf/access_log.conf
Settings: Default filter workers: 6
Logstash startup completed
I have checked your Grok Match filter and is fine with:
Grok Debugger
You don't have to use the date matcher because the grok matcher already correctly match the TIMESTAMP_ISO8601 timestamp.
I think your problem is with "since_db" file.
Here is the documentation:
since_db
In few words, logstash remember if a file is already read and doesn't read it anymore. Logstash remember if one file was already read because write it in the since Database.
If you would like to test your filter reading always the same file, you could try:
input {
file {
path => [ "/tmp/access.log" ]
sincedb_path => "/dev/null"
}
}
