Hi!

I need to use Logstash for parsing \*.gz files. I've downloaded gzip\_lines gem and installed it with

logstash-1.5.1\bin\>plugin install logstash-codec-gzip\_lines-0.1.5.gem

the output said "Installation succesful". After I checked plugin list and found logstash-codec-gzip\_lines there. But when I run Logstash with such input declaration:

file {  
type =\> "gzip"  
path =\> "C:/run/log.gz"  
start\_position =\> "beginning"  
sincedb\_path =\> "gzip"  
codec =\> "logstash-codec-gzip\_lines"  
}

I always have error message:

"Couldn't find any codec plugin named 'logstash-codec-gzip\_lines'. Are you sure this is correct? Trying to lo  
ad the logstash-codec-gzip\_lines codec plugin resulted in this error: no such file to load -- logstash/codecs/  
logstash-codec-gzip\_lines"

What should I do to make it work?

Regards

The "logstash-codec" part of the gem name is added automatically. Try this:

```
codec => "gzip_lines"
```

Magnus,

thank you very much! LS is working now, but plugin still not. Next problem is

←[31mA plugin had an unrecoverable error. Will restart this plugin.  
Plugin: \<LogStash::Inputs::File type=\>"gzip", path=\>["C:/run/calypso.log.gz"], start\_position=\>"beginning", sincedb\_path=\>"gzip", delimiter=\>"\n"\>  
Error: Object: ▼ _some crap_ ??# is not a legal argument to this wrapper, cause it doesn't respond to "read". {:level=\>:error}←[0m

Is anyone got the text from gz file?

Regards

Hi,

I have also got the same requirement, reading .gz file from logstash. Tried with codec gzip\_lines, ended up with the same issue unrecoverable error.

Any solution for this? Please do the needfull.

Thanks,  
Lakshmi.

In my case, I found the problem is the input data of gzip\_lines. Someone who wants to handle gziped text files should offer the filelist as plugin file's input. This problem happens plugin file provide codec gzip\_lines with the data steam of each files. It means codec gzip\_lines get a part of a compressed file. The solution is to offer a file which includes file list as plugin file's option path. We need a preprocessor to process gziped files before starting plugin file.

This is an example.

list\_file.txt

* * *

## /path/a.gz /path/b.gz /path/c.gz

file {  
path =\> "list\_file.txt"  
codec =\> "gzip\_lines"  
}

Thanks for this explanation. Since I'm experiencing the same issue, I gave it another try with your tip.

Unfortunately, it still does not work for me :  
A plugin had an unrecoverable error. Will restart this plugin.  
Plugin: \<LogStash::Inputs::File path=\>["/home/mducruet/list.txt"], codec=\>\<LogStash::Codecs::GzipLines charset=\>"UTF-8"\>, type=\>"akamai-access", debug=\>false, stat\_interval=\>1, discover\_interval=\>15, sincedb\_write\_interval=\>15, start\_position=\>"end", delimiter=\>"\n"\>

I have the same requirement....The logstash reading the gz file but the output is not the "plain" text as in the original file...

I am facing a similar problem, wherein my file is entirely compressed and not line-by-line. Also, the gz files are dynamic, so they cannot be populated in a wrapper file as above. Any solution to get away with this?

**Clone Source**  
`git clone https://github.com/logstash-plugins/logstash-codec-gzip_lines`

**Change gzip\_lines.rb**  
`logstash-codec-gzip_lines/lib/logstash/codecs/gzip_lines.rb`  
line 32 `@decoder = Zlib::GzipReader.open(data)`

> <https://github.com/logstash-plugins/logstash-codec-gzip_lines/blob/master/lib/logstash/codecs/gzip_lines.rb>

**Build Gem File**  
`cd logstash-codec-gzip_lines`  
`gem build logstash-code-gzip_lines.gemspec`

**Reinstall logstash-codec-gzip\_lines**  
`cd logstash`  
`bin/plugin install /opt/logstash-codec-gzip_lines/logstash-codec-gzip_lines-2.0.2.gem`

**Create list.txt File**  
Write by yourself gzip\_lines.rb and run it. It will create list.txt file.

Sample code:  
class GzipLines  
attr\_accessor :list\_path

```
  public
  def create_list(data_path)
    #unless File.exist?(self.list_path)
    open(self.list_path,"w")
    #end

    folders = entries_list(data_path)

    folders.each do |folder|

      files.each do |file|
        open(self.list_path, "a") { |f| f << data_path+folder+'/'+file.to_s+"\n" }
      end
    end
  end

  def entries_list(basedir)
    Dir.entries(basedir).select {|entry| File.directory? File.join(basedir, entry) and !(entry =='.' || entry =='..')}
  end

  def file_list(folder_path)
    Dir.chdir(folder_path)
    files = Dir.glob('*.gz')
  end
end

    gzip_lines = GzipLines.new
    gzip_lines.list_path = '/opt/logstash/list.txt'
    gzip_lines.create_list('/home/tsanchin/rawdata/')

```

**Config logstash.conf to read list.txt file**  
file {  
type =\> "gzip"  
path =\> "/opt/logstash/list.txt"  
start\_position =\> "beginning"  
sincedb\_path =\> "gzip"  
codec =\> gzip\_lines  
}
