Hi,

so the .txt file is on the agent?

Where is the fact from?

Hi,

Yes .txt can be on agent.

The fact is already displayed on agent

Hi,

Just a quick hack.

<!-- HTML generated using hilite.me --><div style="background: #ffffff; overflow:auto;width:auto;border:solid gray;border-width:.1em .1em .1em .8em;padding:.2em .6em;"><pre style="margin: 0; line-height: 125%">     javaversion.rb
    <span style="color: #00aaaa">require</span> <span style="color: #aa5500">&#39;facter&#39;</span>

    <span style="color: #aa0000">Facter</span>.add(<span style="color: #0000aa">:is_javaversion</span>) <span style="color: #0000aa">do</span>
    setcode <span style="color: #0000aa">do</span>
            a = <span style="color: #aa0000">File</span>.readlines(<span style="color: #aa5500">&#39;javaversion.txt&#39;</span>).map { |x| x.chomp }.join
            <span style="color: #0000aa">if</span> <span style="color: #aa0000">Facter</span>.value(<span style="color: #0000aa">:java_known_weblogic_version1</span>) == a
                    <span style="color: #0000aa">true</span>
            <span style="color: #0000aa">else</span>
                    <span style="color: #0000aa">false</span>
            <span style="color: #0000aa">end</span>
    <span style="color: #0000aa">end</span>
    <span style="color: #0000aa">end</span>
</pre></div>

Sorry,

Was trying something..

A clear snippet.

require 'facter'

Facter.add(:is_javaversion) do
setcode do
        a = File.readlines('javaversion.txt').map { |x| x.chomp }.join
        if Facter.value(:java_known_weblogic_version1) == a
                true
        else
                false
        end
end
end

Yes, but is it a custom fact you made? Is it from some module?

I get the feeling you might be over-engineering here.

What is the source of the information in the text file?

I feel that there might be a much cleaner solution than you are
designing. What is the greater problem you are solving?

Hi,

i made a custom fact, I am doing this because my manger wants an alert if the value doesnt match or changed by comparing with the external and the values we are comparing with the facts should be from a txt file not writing the values directly in the .pp file

Can you give me any suggestion?

In this case, I'd write a simple bash plugin for your monitoring
solution of choice, make Puppet distribute that and use monitoring to
keep track of the version match.

This script would use your fact via `facter -p`, or reimplement its
logic, so that you can do away with the fact.

HTH,

Hi,

Do you have any sample script. ?
