Puppet users - Oct 2012 - Possible to exclude an event in Puppet dashboard?

Hi All,

I was wondering if it is possible to NOT show an event in puppet dashboard.
I have an exec resource that fires of a ruby script. This is triggering a
changed event on every run, but actually I want to exclude this from
showing up as "CHANGED"

Is this possible, if so how can I achieve this?

---
myscript:
---

        exec {
            "run_myscript" :
            # run myscript
                command => "/usr/bin/env ruby ${my_script}
${csv_files}",
                cwd => "${myscript_dir}",
                timeout => 0,
                logoutput => "on_failure",
        }

The traditional way to have a script run periodically is to put
something in cron.  Puppet can help you with that.

Thank you Steven,

I''m aware of cron resources I also use them. This particular script is
creating a couple of custom facts, that I''m uploading to the
inventory_service  using puppet facts upload preferably I would like to
have in the same or right after the puppet run.

I was hoping to be able to specify a debug level to logging. ( to dashboard
)

Like debug => true

For now I will create a cron to fire off the script.

Thanks for your reply.

There''s actually a trick you can do with the ''onlyif''
and ''unless''
options to the exec type that can accomplish what you want. The expense
is that you no longer get log output from the command on failure:

        exec {
            "run_myscript" :
                unless => "/usr/bin/env ruby ${my_script}
${csv_files}",
                command => "/bin/false",
                cwd => "${myscript_dir}",
                timeout => 0,
                logoutput => "on_failure",
        }

(This will show up as an error in the puppet run if the command fails,
but not show up at all if it succeeds.)

However, you mentioned something about facts generation in a later post?
Do keep in mind that facts are uploaded to the puppet master *before*
any of the code in your manifest executes, so anything done in your
manifest will only affect the facts for the next puppet run.

Thank for this suggestion Calvin,

I''m uploading facts to the inventory as part of this manifest.

I have a bunch of files I want to monitor. This can be random files. I
created a small script in ruby to check the existence of those files and
check the current md5sum. If the sum is not in my log, or the file has been
added to the list of files that need to be monitored, that file is being
send to the puppet filebucket and the file plus sum is added as a customer
fact.

The last step in my script will do a `puppet facts upload  --terminus
inventory_service --mode agent` if any of the files has been changed. This
trick is here just for the reason you mentioned. The facts are
''known'' to
others in the next run. I need this information directly.

Thanks again for your hint. Will be the first thing I try tomorrow.
