Userparameter with Foreman

[georgesouzafarias]

I'm using your puppet module in my environment. I haven't a lot of experience with puppet, but I'm using the foreman's web interface to manager my configurations.

My questions is:

How to configure userparameter using the web interface?

For example:

userparameter=pje.available,/usr/local/sbin/test_pje

Thank you

Hello!
@georgesouzafarias,did you find the answer?

[georgesouzafarias]

No, I'm waiting for.

Actually I found a solution.
As Dominic said here https://groups.google.com/d/msg/foreman-users/o-Sqjo-n21A/66pEAIG17PYJ

You can't instantiate resources (defined types, or native) over the
Puppet ENC interface. Maybe use create_resources instead, e.g.

define foo($a, $b) { 
 notify { "$title: got $a and $b": } 
} 

class createfoo($data){ 
create_resources(foo, $data) 
} 

Then in foreman for the createfoo class, set the data parameter to:

--- 
data: 
 first: 
   a: "param 1a" 
   b: "param 1b" 
 second: 
   a: "param 2a" 
   b: "param 2b" 

So I've created module on puppet master puppet module generate nrzabbix and in manifests/init.pp I've put

class nrzabbix($data){
        create_resources(zabbix::userparameters, $data)
}

Then in foreman UI I've imported newly created module. It has only one smart parameter data which could be overridden in foreman

For example my UserParameter for montoring mongodb is described as

mongo:
  source: puppet:///modules/nrzabbix/mongo.conf

And content of nrzabbix/files/mongo.conf is

UserParameter=mongo.coll.count[*],echo "db.setSlaveOk();db.getCollection('$1').count()" | /opt/mongo/bin/mongo processor | sed -n 3p
UserParameter=mongo.db.queries,echo "db.currentOp().inprog.length" | /opt/mongo/bin/mongo processor | sed -n 3p

Then I've added this class to certain config group for my mongodb servers.
In YAML for a host I've got

---
classes:
  nrzabbix:
    data:
      mongo:
        source: puppet:///modules/nrzabbix/mongo.conf

On a host:

[root@nr-db-cl-c3 ~]# puppet agent -t

and

[root@nr-db-cl-c3 ~]# cat /etc/zabbix/zabbix_agentd.d/mongo.conf
UserParameter=mongo.coll.count[*],echo "db.setSlaveOk();db.getCollection('$1').count()" | /opt/mongo/bin/mongo processor | sed -n 3p
UserParameter=mongo.db.queries,echo "db.currentOp().inprog.length" | /opt/mongo/bin/mongo processor | sed -n 3p

Hope this could help

Hi @inspired-geek

Thank you for this reply.

You could use this class: 'zabbix::userparameter.pp' instead of creating your own.
(Without the s.. ;-))

Can I update the readme for using userparameters with this information you provided?

Thanks!

[inspired-geek]

@dj-wasabi, of course you could!
It's non-obvious so I felt the need to dive deep into details :)

Hi, class zabbix::userparameter.pp has no smart class parameter
This Puppet class has no parameters in its signature.
To update the class signature, go to the Puppet Classes page and select "Import".

Foreman 1.9.2

[chernogorsky]

class zabbix::userparameterf($data) {
validate_hash($data)
create_resources('zabbix::userparameters', $data)
}

This work as expected
