I have a very simple pipelines.yml file defined with a single pipeline. It looks like this:
- pipeline.id: testPipe1
path.config: "/tmp/test.conf"
pipeline.workers: 1
when starting logstash I received the following error:
ERROR: Failed to read pipelines yaml file. Location [path to file].pipelines.yml
, where "path to file" is valid path to yaml file.
the contents of test.conf are:
input { stdin {} } output { stout {codec => rubydebug} }
when I comment out path.config line and use:
config.string: input { stdin {} } output { stout {codec => rubydebug} }
, then logstash creates the pipeline and starts up fine.
What is going on here? Grateful for any insights. thanks
One thing to note is pipelines (with .conf extension) are considered config. Settings (with .yml) extension are your settings. I would separate these into two different directories then run the command line this.
./bin/logstash --path.settings /path_to_your_yml_settings_dir --path.config=/path_to_your_conf_pipelines
Your pipelines.yml file should be placed at "--path.settings" which you would pass on the command line when starting logstash process. Something like:
./bin/logstash --path.settings /path_to_your_settings_dir_containing_your_configs_and_pipelines.yml
Passing the path to my pipelines.yml in --path.settings when starting Logstash did not work out for me.
Removing the quotation marks in path.config worked:
- pipeline.id: testPipe1
path.config: /tmp/test.conf
pipeline.workers: 1
Then run ./bin/logstash

I want to write output file on logstash, but logstash can't write file. file is empty and i can see logs on Kibana Dashboard.
My output.conf file ;
output {
file {
path => "/home/freed/example.txt"
codec => line { format => "custom format: %{message}"}
}
}
I want to help ?
I suspect that you have problems accessing (permission) the file for the logstash.
Check you log: /var/log/logstash/logstash-plain.log
In you example logstash must have accessing to /home/freed and be the owner file example.txt
Version: ElasticSearch-5.2.1/Logstash-5.2.1/Kibana-5.2.1
OS: Windows 2008
I've just started working on the ELK Stack & am facing some problems loading data
I've got the following .json code
input {
file {
path => "D:\server.log"
start_position => beginning
}
}
filter {
grok {
match => ["message","\[%{TIMESTAMP_ISO8601:timestamp}\] %{GREEDYDATA:log_message}"]
}
}
output {
elasticsearch {
hosts => "localhost:9200"
}
}
I've deleted the .sincedb files
And yet when I extract log info in Kibana, I can see data starting only since I first parsed. I've got data worth 2-3 months in my log file.
What if you have your file input as such, where you're missing out the ignore older which actually will stop you re-reading the old files plus you're missing out the since db path property I believe. You could have a look up on this answer by #Steve Shipway for a better explanation on having these two properties within your file input.
So your input could look something like this:
input {
file {
path => "D:\server.log"
start_position => "beginning" <-- you've missed out the quotes here
ignore_older => 0
sincedb_path => "/dev/null"
}
}
Note that setting sincedb_path to /dev/null will make the files read from the beginning, every time which isn't a good solution at all. But then deleting the .sincedb file should work I reckon. If you really want to pick up lines from where you left off, you really need the .sincedb file to hold into the last position which got updated lastly. You could have a look on this for a detailed illustration.
Hope this helps!
in my case, when you enter systemctl restart logstash, even if you have deleted the sincedb file, logstash before the process closes save a new sincedb file and then closes.
if you want really read file from beginning, you should:
stop the logstash service: sudo systemctl stop logstash
delete sincedb file from /var/lib/logstash/plugins/inputs/file or /usr/share/logstash/data/plugins/input/file directory
start the logstash service: sudo systemctl start logstash
I've a logstash instance, version 2.3.1 which isn't running using the command
sudo service logstash start
Whenever I run this command, it returns logstash started and after a few moments when I check the status, I find that logstash isn't running. Although, when I start the logstash from opt to get output on the terminal, it runs without any error.
Note that logstash.err and logstash.stdout files are empty and logstash.log file isn't anywhere to be found. I've also set LS_GROUP to adm in init.d which caused the same issue on another instance, but even that doesn't seem to work now. Any help would be appreciated!
On an Ubuntu system, this behavior can be seen by logstash. To get around it, you can change the logstash user group in /etc/init.d/logstash to adm which stands for admin and you're good to go.
This is normal behaviour of Logstash.
Can you test if your Logstash instance is working correctly?
Windows:
Go to your bin folder of logstash
and type logstash
Linux:
Enter this command in the prompt (bin folder of your logstash instance)
/opt/logstash/bin/logstash
Both:
If you get No command given ... you're logstash instance has the correct setup.
You can always run your Logstash instance with this command
logstash -e 'input { stdin { } } output { stdout {} }'
After this you can enter some text values and they will output to your console.
If this all works you can be sure that your Logstash instance is running correctly.
You may ask yourself why is this? This is because Logstash waits to start untill it gets a config to run with or another option.
If you want to start Logstash automatically on startup. You need to use this command.
sudo update-rc.d logstash defaults 96 9
Actually,you should read the guide of logstash.In the "getting started section",The official documentation has the corret way for you to start a logstash work.
First,you should write a configure file such as "std.conf",look like this:
input {
stdin {
}
}
output{
stdout{
codec=>rubydebug
}
}
Then,start your logstash:
bin/logstash -f conf/std.conf
If you want this work can run in the background(such as get some log files into elasticsearch),you may also need add "&" in the end of the command,like this:
bin/logstash -f conf/getlog.conf &
with this file(std.conf) and this command,your logstash will start up and if you type any word in you terminal,it will print out in the terminal,like this:
{
"message" => "hello",
"#version" => "1",
"#timestamp" => "2016-08-06T19:47:36.543Z",
"host" => "bag"
}
Now,you have got the normal operation of logstah,you may need more information,from there:The official documentation of logstash
Try this,and keep going,it`s easy for you~
I am able to run logstash as:
bin/logstash -f /etc/logstash/conf.d/config.json
but running logstash as a service
sudo service logstash start
is giving me the following error:
... Error: Expected one of #, input, filter, output at line 24, column 1 (byte 528) after "}
Not sure what I am doing wrong here? Configtest also says the config file is fine.
bin/logstash -f /etc/logstash/conf.d/config.json --configtest
Configuration OK
Any help is appreciated.
Thanks.
When logstash runs, it combines all the files in your config directory into one file. When there's an error, you're getting line and position information into that merged config.
Try:
cat /etc/logstash/conf.d/* > /tmp/total.conf
and then look at line 24 or 25 there.
FYI mine complains about line about line 163 and my combined files don't get that far.
Here someone had left an ~.vimrc file in the conf.d directory, which was then appended to the big configuration file.
--configtest probably ignores the file, but reading configs did not.
How to install logstash on Windows 7?
I install zip file which size is 90 mb and then version is logstash-1.5.0
and extract then file and move it to the bath C:\Logstash
When I run:
C:\Logstash\logstash-1.5.0\bin\logstash
I have the following message:
io/console not supported; tty will not be manipulated
No command given
Usage: logstash [command args]
Run a command with the --help flag to see the arguments.
For example: logstash agent --help
Available commands:
agent - runs the logstash agent
version - emits version info about this logstash
any help
thank you
The most simple way to get started and verify that your logstash is working is to start it with the following command
logstash -e 'input { stdin { } } output { stdout {} }'
this means that logstash will echo what you type in the console back out to the console, for example:
C:\logstash\bin>logstash -e 'input { stdin { } } output { stdout {} }'
io/console not supported; tty will not be manipulated Settings:
Default filter workers: 4 Logstash startup completed
I typed this
2015-12-11T09:22:22.349Z MY_PC I typed this
and then I typed this
2015-12-11T09:22:26.218Z MY_PC and then I typed this
The next thing to do is read an input from something else, for example your windows logs. For this you can save a config file to your bin folder, it can be called anything, for instance 'logstash.config'. Contents as below
# contents of logstash\bin\logstash.config
input {
eventlog {
type => 'Win32-EventLog'
logfile => 'System'
}
}
output {
stdout { }
}
If you then run
logstash -f logstash.config
Leave this running for a bit and you will see that your windows event log gets written out to the console. (You could trigger some events by running iisreset in a different console.)
not sure why is says "io/console not supported; tty will not be manipulated", probably because it is running in a windows console, but logstash is still working.
Make a conf file and paste it in bin folder of logstash
and type
in cmd logstash/bin>logstash agent -f logstash.conf
You have to run logstash manually by command in windows 7. tc-log.conf is my conf file. lslog.log is my log file. Change directory to the bin folder of logstash and run following command .
*make sure that you have done changes in command as per yours.
logstash agent -f D:/cloud/logstash-1.4.2/tc-log.conf -l D:/cloud/logstash-1.4.2/logs/lslog.log –verbose
I tried this method but using the test command I obtained:
Cannot find Java 1.5 or higher.
I have %LS_HOME%, %JAVA_HOME% and the PATH updated.
Debugging the logstash.bat (with echo) I found error is raised by:
%JRUBY_BIN% "%LS_HOME%\lib\bootstrap\environment.rb" "logstash\runner.rb" %*
%JRUBY_BIN% and "%LS_HOME% are rightly defined:
- "C:\ELK\logstash\vendor\jruby\bin\jruby"
- "C:\ELK\logstash"
Thanks.
