Hi All,

I am trying to get all the java versions and paths where it is located. I got all java_paths in a fact called java_path. Now i need those versions in each custom facts.

I wrote a code but this not executing .

Please help me

require 'rexml/document'
require 'facter'

Facter.add("java_path") do
  setcode do
    Facter::Util::Resolution.exec('/home/suppalapati/java.sh')
    end
end




logfile = '/home/suppalapati/java.txt'

line_num=0

log = Facter::Util::FileRead.read(logfile)
unless log.nil?
  log.each_line do |line|
    if line.include?('java')
       line_num += 1
       javaid, val =  %x[ #{log} ]
    Facter.add("java_#{javaid}") do
      setcode do
         val
        end
       end
     end
   end

 Facter.add("java_version_count") do
  setcode do
    line_num
  end
 end
end


Here is my java.txt file

/usr/java/jre1.7.0_51/bin/java
/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/jre/bin/java

Can you provide more details about how it isn't  executing? Is it producing an error? Are any of your facts showing up (java_version_count for example)? Are you sure that you've put the custom fact file in the correct location? Have you followed the guide at https://docs.puppetlabs.com/facter/2.2/custom_facts.html for how to write and use custom facts?

Hi,

It isn't executing anything. it means it is not showing individual fact for each java version. yes my facts(java_version_count ) is showing me how many lines(means java) i have in java.txt. yes i placed in wright location.I followed the  link which you provided me.

I feel some thing is wrong here, i think

logfile = '/home/suppalapati/java.txt'

line_num=0

log = Facter::Util::FileRead.read(logfile)
unless log.nil?
  log.each_line do |line|
    if line.include?('java')
       line_num += 1
       javaid, val =  %x[ #{log} ]
    Facter.add("java_#{javaid}") do
      setcode do
         val
 

Can you correct me?


Thank You

A useful tool to understand and debug ruby code is irb. With irb you can try out your code interactively. To try out some of your code here you can do:

> irb
1.9.1 :001 > require 'facter'
 => true
1.9.1 :004 > require 'facter/util/file_read'
 => true
1.9.1 :005 > hosts = Facter::Util::FileRead.read("/etc/hosts")
 => ....
1.9.1 :007 > hosts.each_line do |line|
1.9.1 :008 >     puts line
1.9.1 :009?>   end
  ....

logfile = '/home/suppalapati/java.txt'

line_num=0

log = Facter::Util::FileRead.read(logfile)
unless log.nil?
  log.each_line do |line|
    if line.include?('java')
       line_num += 1
       javaid, val =  %x[ #{log} ]

If you try running one of these lines you'll see what is happening:

1.9.1 :012 >   javaid, val = %x{java}
  ...lots of output...
1.9.1 :013 > javaid
  ...same output as above...
1.9.1 :014 > val
  => nil

So you are ending up with nil as the value of your fact and the name of the fact is the output of your command. You can't assign the output of a process execution to a list of variables, only the first variable will receive a value. You'll need to parse the output of that command to get whatever value it is that you are looking for.

Hi Andrey,

When i tried your example, It is not returning any values

Hi,

My question is 

require 'facter/util/file_read'
=> true
irb(main):005:0> log = Facter::Util::FileRead.read("/home/suppalapati/java.txt")
=> "\n/usr/java/jdk1.7.0_25/jre/bin/java\n/usr/java/jdk1.7.0_25/bin/java\n/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.45.x86_64/jre/bin/java\n/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/jre/bin/java\n\n"
irb(main):006:0> log.each_line do |line|
irb(main):007:1* javaid, val = %x{line}
irb(main):008:1> javaid, val = %x{java}


It is not returning anything. My question is something i am doing wrong here to get the out. I understood the factname and the output of the factname should be different. But it is not showing any output when the running the command itself.  

Help me

You won't get any output until you enter "end". IRB will only execute complete statements. Instead of simply assigning the output of the command to a variable in irb you'll be better off if you print it out as well.

log.each_line do |line|
  val = %{#{line}}
  puts val
end

Supriya, you don't seem to be having a problem with developing against facter or puppet here, which is the purpose of this mailing list. You seem to be having problems understanding and writing a program in ruby in general. I suggest that you take some time to read some tutorials, try some exercises, and learn how to write, understand, and debug ruby. There are many mailing lists and websites that can help you with that. If you search for "ruby tutorial" or "ruby command execution" you'll find many pages that cover aspects of the language. The ruby language website also has links to a large number of tutorials that others have found helpful (https://www.ruby-lang.org/en/documentation/). Please use this list for suggestions or questions about how to develop on or against puppet or related tools.
 


Where is in the facts it is not showing anything:
$/opt/puppet/bin/facter -p | grep -i java_*

Here is my code:
logfile = '/home/suppalapati/java.txt'

line_num=0

log = Facter::Util::FileRead.read(logfile)
unless log.nil?
  log.each_line do |line|
    if line.include?('java')
       line_num += 1
       javaid, val = %x[#{log}]
    Facter.add("java_#{javaid}") do
      setcode do
         puts val

Facter considers a fact that has a nil return value from the setcode block to not exist. "puts" returns nil. In your previous examples, as well as this one, "val" evaluated to nil. The %x[] command does not return two values, which is why "val" is nil (http://www.ruby-doc.org/core-2.1.3/Kernel.html#method-i-60). You also are executing "log" instead of "line".

Hi Andy,

The way i approach for this, was i took my code and first run it in ruby parser and also in my test server to execute first in ruby.After executing that ruby script then i tried to convert ruby script into puppet facts. like Facter.add to retireve the result.

My question was, when i executed in ruby it is showing me exact result what i need. But in the facts it is not returning any value. even though  i removed puts and replaced log with line
