Logstash service doesn't want to read my conf file in /etc/logstash/conf.d/.
Service is running all the time.
For example:
...
output {
stdout { codec => rubydebug }
file { path => "/home/vagrant/LOGSTASH_TEST.txt" }
}
And nothing is added to the file.
But when I'm running bin/logstash -f /etc/logstash/conf.d/myconfig.conf — everything is fine.
/etc/init.d/logstash is looking good:
LS_CONF_DIR=/etc/logstash/conf.d
...
program=/opt/logstash/bin/logstash
args="agent -f ${LS_CONF_DIR} -l ${LS_LOG_FILE} ${LS_OPTS}"
What could be the problem?
Try changing /etc/init.d/logstash to:
LS_CONF_DIR=/etc/logstash/conf.d
LS_CONF_FILE=myconfig.conf
...
program=/opt/logstash/bin/logstash
args="agent -f ${LS_CONF_DIR}/${LS_CONF_FILE} -l ${LS_LOG_FILE} ${LS_OPTS}"

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.
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"
}
}

I am new to logstash on ubuntu. I am using file plugin in the input where I have given the path for displaying the content of the file on the stdout.This is my configuration file
input{
file{
path =>"/home/om/Desktop/app/logstash/logstash-1.4.22/logs.txt"
start_position => "beginning"
}
}
output{
stdout{}
}
I am not getting any output on the console. I want to dump the data from the .txt file on the console.
Use this configuration:
input {
file {
path => [ "\\IpAddress\logs/filename.*.*_bak"" ]
start_position => "beginning"
}
}
output {
elasticsearch {
bind_host => "127.0.0.1"
port => "9200"
protocol => http
}
stdout { codec => rubydebug }
}
And also checking with below commands:
>logstash --configtest -f logstash.conf --> for configuration testing
>logstash --debug -f logstash.conf --> for debugging
I am new to logstash and docker.
I am using logstash container to retrieve logs, generated by other application. As i am able to run container successful but i am not getting the output in my file "finalOuput.log" [ both the file finalOuput.log & pipeline.conf is in container]
1->
My Docker File Content:
FROM logstash
copy pipeline.conf /var/app/
copy finalOuput.log /var/app/
CMD ["-f", "/var/app/pipeline.conf"]
2-> My pipeline.config file contains
input {
file {
path => "/predix/Documents/workspace-sts-3.8.1.RELEASE/sendRohit/9aug/application-logs/application-log.log"
}
}
filter {
grok {
match => { "message" => "%{COMBINEDAPACHELOG}"}
}
}
output {
file {
path => "/finalOuput.log"
codec => line { format => "custom format: %{message}"}
}
}
Now i am getting the data. Need to put the pipeline.conf in the root directory of container.
FROM logstash
run mkdir rvol
copy third-pipeline.conf /
copy outputdata.log /rvol/
copy inputData.log /rvol/
CMD ["-f", "/third-pipeline.conf"]
And then fire the command: Below command is single command
docker run -d --name=container_Name -v '/predix/Documents/rvol/inputData.log':'/rvol/inputData.log' -v '/predix/Documents/rvol/outputdata.log':'/rvol/outputdata.log' image_Name
