Re: [Puppet Users] Dynamic Nagios Hostgroup members via collected resources?

I admit I'm somewhat new to this game, so please excuse my ignorance on the complexities. I'm looking for a way that puppet can use collections / exported resources to create nagios host groups. For instance, I'd like a hostgroups for osfamilies, puppet environments, domains, and perhaps virtual or hardware platform. It seems like using @@nagios_hostgroup on the nodes, and collecting the resources on the Nagios server is not sufficient, when what I'm looking for is one hostgroup named RedHat with members of this osfamily, and another hostgroup named Solaris whose members are of the solaris osfamily. I've not had much success writing this into puppet, so is this just not possible? Would I be better served creating custom resource(s) that simply collect lists of node names by the facts I'm interested and then the Nagios server uses those collections as data to populate its set of nagios_hostgroup resources? Thanks for your thoughts and wisdom. I think that the only real way to do this properly is to not realize nagios resources in the standard way. Check https://github.com/dalen/puppet-puppetdbquery out and see if you can do your nagios configuration with it.

[Puppet Users] Re: Help on Hiera automate
Thanks Jc,
i did what you said..i have changed .yaml like this:
servers:
s10:
sn: de3de
project: b
user: b
dbname: de
dbuser: e
dbpwd: de
s16:
sn: de3dedede
project: b

...
and obtain params like this hiera('servers') and use create_resources

Try adding the parameter logoutput = on_failure to the 'exec' and
re-run puppet. It should drop the output of the make command to the

[Puppet Users] Re: Write a function to puupet
On Wednesday, January 15, 2014 4:28:41 AM UTC-6, shlo@gmail.com wrote:
Hi,
I want to write a function for Puppet that check if package already

define safepackage ( $ensure = present ) {

package { $title: ensure = $ensure }
}
}
In which file I need put this function so all other modules can access
it? because I'm getting 'unknown function...' error.
That's not a function, it's a defined type. You declare instances just as
you would declare instances of a built-in type, such as Package itself.
You cannot call it as if it were a function. You really ought to put it
into a module, though.
With that said, what you propose to do is one of the persistent bad ideas
in the Puppet universe. Using such a definition to allow multiple points
of declaration of a given resource (only one of which will be effective)
makes your manifest set harder to maintain and opens it to subtle bugs
because you must keep all declarations of the target resource
synchronized. If you don't, then your manifest set thereby has an internal
inconsistency that you prevent Puppet from diagnosing. All manner of
strangeness may then ensue. Moreover, the approach is only effective for a
given resource if you apply it to every declaration of that resource.
The best way to avoid multiple-declaration errors is to factor out multiple
declarations of any given resource into a single class that the other
erstwhile declaration points will rely on. That is usually fairly
natural. It may involve modifying third-party modules, but so does any
approach based on the defined() function or similar.

Re: [Puppet Users] Re: Puppet calls the ENC twice for some nodes.
On Tuesday, January 14, 2014 5:20:55 PM UTC-6, James Ellis wrote: Hi, chanced across this discussion when I noticed an ENC was being called twice. I understand I may not be using the ENC terminus exactly as it's been designed, but it's unexpected that it was called twice. Also worth noting that I can't see a note about the ENC being called twice here: http://docs.puppetlabs.com/guides/external_nodes.htmlhttp://www.google.com/url?q=http%3A%2F%2Fdocs.puppetlabs.com%2Fguides%2Fexternal_nodes.htmlsa=Dsntz=1usg=AFQjCNFK7HQpajIuPvlZjm7asakMiSwElg True, but the docs also don't say it's called only once. If you read between the lines, you might infer that it can be called multiple times. In particular, consider this excerpt from the doc: In Puppet 3 and later, ENCs can set an environment for a node, overriding whatever environment the node requested. However, previous versions of Puppet use ENC-set and node-set environments inconsistently, with the ENC’s used during catalog compilation and the node’s used when downloading files. The reason for the inconsistency in Puppet 2 is that file downloads occur in separate request contexts, and that version of Puppet did not re-run the ENC for each of those as it would have needed to do to compute the appropriate environment correctly. To be sure, the docs could be clearer on the point. Feel free to file an RFE. In my case, I'm using an ENC to push virtual host changes to an agent running a web server, the YAML returned by the ENC uses create_resources to dynamically add resources to the catalogue. I observed via logging in the ENC script that on the first run, the ENC was excecuted but the catalogue was not applied, on the second run the catalogue was applied on the agent. By default, the agent issues at least two web requests to the master on every run because it first synchronizes plugins, then requests a catalog. It may make other requests as well, to retrieve plugin contents when it determines those are needed, or to retrieve 'source'd files. All of those requests require the master to determine the node's environment to provide correct service, and determining the environment requires running the ENC, if there is one. This causes problems where we use an API to dynamically apply resources to a catalogue (1st run gets the catalogue resources, returns 'OK' to the API, 2nd run then tries to get resources but gets nothing as the 'OK' sent to the API has effectively modified the resources to be applied). I've worked around this, for now, by using a lock file, so that the 'OK' API call is only run once but this still applies two calls to the API to dynamically get resources for the catalogue, where only one is required. I double checked the master and the agent configs, and the master only shows the ENC being referenced once and there is one agent being run, only. Based on this, is there any way the agent can be set to call the ENC once only ? The only argument to the script is the agent hostname and there is no apparent difference in the environment of the first and second ENC calls. If you disable pluginsync at the agent and avoid declaring any 'source'd File resources pointing back to the master, then I think the agent will make only one request to the master per catalog run. In that case, the master should run the ENC only once for that catalog run. Disabling pluginsync may make it difficult to insert certain new modules into your Puppet infrastructure or to update such modules, and avoiding 'source'd Files will require great discipline and vigilance. I would think twice before going that route. Instead, if you want to stick with your current ENC concept then you should consider how your ENC might recognize multiple calls associated with the same catalog run. I think node facts are updated only once per catalog run, after pluginsync and just prior to running the ENC to kick off catalog compilation. Perhaps, then, you could watch each node's 'uptime_seconds' fact, and perform your once-per-catalog-run work only if the value of that fact is different from what it was during the previous run of the ENC for the given node. The doc you referred to has a bit of information about how the ENC can access node facts. John -- You received this message because you are subscribed to the Google Groups Puppet Users group.

What i have not found so far is a Hiera tutorial I understand, i read through puppetlabs docu but i dont understand it.

I think ridiculous and bizarre is a bit strong. It's strange that
the type selects one element and ignores the rest, but it's not so
surprising that's what's wanted in the first place is whatever string
is supposed to be plugged in to the corresponding hole in the Nagios
config file. That's even a viable way to read the documentation for
the type. And I certainly don't understand what any of this has to do
with the whole point of having a managed resource.
John,
I'm sorry for my outburst yesterday - quite embarrassed to read my
message back again :\ I was just a bit frustrated to run into bugs
and/or unexpected behaviour when I also had some of our dev/ops guys on
my back wondering when I was going to fix their monitoring notifications.
Hulk smash, Hulk do Nagios configs!
I think what I meant was - data structures within Puppet and Hiera are
almost always handled as arrays or hashes, and when you call upon other
classes and resources you would tend to pass it an array or a hash. I
was surprised that this isn't the case for nagios_* types, which expect
a comma-delimited format.
There's a workaround using templates as a filthy hack:
# manifest.pp
nagios_host { $fqdn:
address = $ipaddress,
hostgroups = template(join_hostgroups.erb)
}
You seem angry about this. I don't understand why.
Yeah, today I'm not sure why either. I guess it seems a less elegant
solution (and potentially more expensive in terms of resources on an
already busy puppetmaster). It's the first time I've had to do something
like this (I guess that makes me lucky).
Anyway, if you have Puppetlabs's stdlib add-in module installed,
then it provides a join() function that can replace the template. Or
at minimum it would probably be better to use an inline_template()
instead of an external one.
After my email yesterday, I changed my approach to use an
inline_template() which works nicely. Also good to know that there's a
join() function for for joining arrays - thanks for the tip. We do
already have stdlib installed, but only as a dependency for other
forge modules - I've never called upon its functions myself. Thanks for
the tip - I'll check it out tomorrow (now after 4pm here and we're not
allowed to make changes in case we break stuff!)
Sorry again for my rage, and thanks for your advice. If you're ever in
Bristol (UK), I'll buy you a pint :)
Cheers,
Jonathan

Re: [Puppet Users] Doubt about lots of persistent connections
Those connections don't take much in the way of resources on the ActiveMQ server (you might need to up the number of open files the activemq process is able to access). I'm not sure what you mean about non-persistent connections; are you talking about agents periodically connecting to check? i'd expect the continual connection setup/teardown to put more load on the MQ server that 1000 or so idle connections (with maybe the occasional keepalive). STOMP is pretty lightweight.

[Puppet Users] Using Virtual Resources and create_resource combination
Hi friends,
I have an issue where that I receive error Error 400 on SERVER: Cannot
reassign variable name on node app1. When I run the agent on admin1 it
works fine, but when I run the agent on app1 it give me the error.
Having read few forum posts it seems this is most likely that the same
resource is used. resource network::if::static is used with eth0 in the
same class when it runs for admin1 and app1. I believe when it run on
admin1 variables are used without any problem and when it run on app1 it
find the variable has been used for admin1. It appears these kind of issues
are addressed by creating virtual resources. However I cannot figure out
how I can define virtual resources and combine that with create_resources.
I need to use the create_resources because I was to pass the hieradata to
the resource.
*Any ideas how I can address this problem?*
Details of the implementation given below:
I have following hieradata which applied to each server:
/etc/puppet/hieradata/admin1.json
{
networks:{
eth0:{
ipaddress:192.168.1.1,
netmask:255.255.255.0
}
}
}
/etc/puppet/hieradata/app1.json
{
networks:{
eth0:{
ipaddress:192.168.1.2,
netmask:255.255.255.0
}
}
}
I have a class call foundation and it has following files
/etc/puppet/modules/foundation/manifests/init.pp
class foundation {
include foundation::network
}
/etc/puppet/modules/foundation/manifests/network.pp
class foundation::network{
# Defaults for network configuration
$nic_default = {
'ensure' = 'up'
}
# Extract Data from Hiera for the host in concern
$nics = hiera(networks,{})
# Configure networks based on the parameters
create_resources(network::if::static, $nics, $nic_default)
}
Above class is included in base node and individual nodes has extended from
the base node
/etc/puppet/manifests/nodes.pp
node base {
include foundation
}
node admin1 inherits base {
}
node app1 inherits base {
}
Thanks,
CD

[Puppet Users] ssh module dependency failure
Hi All,
I'm writing to you today because I am attempting to follow along in the
Pro Puppet book I am attempting the ssh module example from page 39.
I am getting the following error on the client when I try to implement it:
[root@beta:~] #puppet agent --test --server puppet.mydomain.com
info: Caching catalog for beta.mydomain.com
err: Failed to apply catalog: Could not find dependency Class[Ssh:install]
for File[/etc/ssh/sshd_config] at
/etc/puppet/modules/ssh/manifests/init.pp:16
This is the class I have defined on the puppet server:
class ssh::install {
package { openssh:
ensure = present,
}
}
class ssh::config {
file { /etc/ssh/sshd_config:
ensure = present,
owner = 'root',
group = 'root',
mode = 0600,
source = puppet:///modules/ssh/sshd_config,
require = Class[ssh:install],
notify = Class[ssh::service],
}
}
class ssh::service {
service { sshd:
ensure = running,
hasstatus = true,
hasrestart = true,
require = Class[ssh::config],
}
}
class ssh {
include ssh::install, ssh::config, ssh::service
}
And this is the definition I tried to copy from the book:
class ssh::install {
package { openssh:
ensure = present,
}
}
class ssh::config {
file { /etc/ssh/sshd_config:
ensure = present,
owner = 'root',
group = 'root',
mode = 0600,
source = puppet:///modules/ssh/sshd_config,
require = Class[ssh::install],
notify = Class[ssh::service],
}
}
class ssh::service {
service { sshd:
ensure = running,
hasstatus = true,
hasrestart = true,
enable = true,
require = Class[ssh::config],
}
}
class ssh { include ssh::install, ssh::config, ssh::service }
However I can't tell what the differences are that prevent the version I
keyed in from working. I've even created a diff of the two files with the
same order of files that you see above (mine first , theirs second)
[root@beta:~] #cat ssh_diff.txt
1,5c1,5
class ssh::install {
package { openssh:
ensure = present,
}
}
---
class ssh::install {
package { openssh:
ensure = present,
}
}
7,17c7,17
class ssh::config {
file { /etc/ssh/sshd_config:
ensure = present,
owner = 'root',
group = 'root',
mode = 0600,
source = puppet:///modules/ssh/sshd_config,
require = Class[ssh:install],
notify = Class[ssh::service],
}
}
---
class ssh::config {
file { /etc/ssh/sshd_config:
ensure = present,
owner = 'root',
group = 'root',
mode = 0600,
source = puppet:///modules/ssh/sshd_config,
require = Class[ssh::install],
notify = Class[ssh::service],
}
}
19,26d18
class ssh::service {
service { sshd:
ensure = running,
hasstatus = true,
hasrestart = true,
require = Class[ssh::config],
}
}
28c20,30
class ssh { include ssh::install, ssh::config, ssh::service }
---
class ssh::service {
service { sshd:
ensure = running,
hasstatus = true,
hasrestart = true,
enable = true,
require = Class[ssh::config],
}
}
class ssh { include ssh::install, ssh::config, ssh::service }
Could I possibly borrow a fresh pair of eyeballs that might be able to
recognize what's wrong?
Thanks

Re: [Puppet Users] Re: Puppet calls the ENC twice for some nodes.
Thanks Jason for the info. Bear with me, but I'm still unsure why the ENC would run twice, particularly given the dynamic nature of an ENC terminus where it would be connecting to other systems to get information for a catalogue -- those systems are then hit twice, regardless of whether or not the same information is returned, which seems a waste of resources (e.g maybe the external system has a quota limit ?) I see in our logs running twice when the agent, in verbose mode, outputs Info: retrieving plugin and then another run when it outputs Info: Caching catalog for ... In relation to applying changes to a virtual hosting setup, I'll look at other options. Given a quick example of say a domain 'enc.example.com' being created, then the customer fails to pay for their domain or hosts elsewhere, such that it should be deleted, the ENC should then provide this account for deletion in the catalogue, so that it is removed on the relevant server. I understand that this is changing the catalogue information across ENC runs but how else would this change be provided to the agent ? Regards James On Wednesday, 15 January 2014 12:40:39 UTC+11, Jason Antman wrote: James, I vaguely remember seeing this 'node_terminus called twice' thing in the past. The simple answer, though I know it's not what people want to hear, is that the ENC should always return the right information. If you want to modify the content of the catalog based on something that happens between runs (which, by the way, I would highly suggest against, and suggest that if you're doing that, something in your puppet configuration is amiss), you should be checking somewhere like PuppetDB, not changing it based on how many times the ENC script is run. Aside from the problem you're having now, what happens if there's a timeout, or some other failure after the ENC script is called but before the catalog is applied? -Jason On 01/14/2014 06:20 PM, James Ellis wrote: Hi, chanced across this discussion when I noticed an ENC was being called twice. I understand I may not be using the ENC terminus exactly as it's been designed, but it's unexpected that it was called twice. Also worth noting that I can't see a note about the ENC being called twice here: http://docs.puppetlabs.com/guides/external_nodes.html In my case, I'm using an ENC to push virtual host changes to an agent running a web server, the YAML returned by the ENC uses create_resources to dynamically add resources to the catalogue. I observed via logging in the ENC script that on the first run, the ENC was excecuted but the catalogue was not applied, on the second run the catalogue was applied on the agent. This causes problems where we use an API to dynamically apply resources to a catalogue (1st run gets the catalogue resources, returns 'OK' to the API, 2nd run then tries to get resources but gets nothing as the 'OK' sent to the API has effectively modified the resources to be applied). I've worked around this, for now, by using a lock file, so that the 'OK' API call is only run once but this still applies two calls to the API to dynamically get resources for the catalogue, where only one is required. I double checked the master and the agent configs, and the master only shows the ENC being referenced once and there is one agent being run, only. Based on this, is there any way the agent can be set to call the ENC once only ? The only argument to the script is the agent hostname and there is no apparent difference in the environment of the first and second ENC calls. Using 3.4 O/S on ubuntu with the following agent command (run as root manually to debug) : puppet agent --no-usecacheonfailure --onetime --no-daemonize --server valid.server --verbose Thanks James On Monday, 23 September 2013 23:59:45 UTC+10, jcbollinger wrote: On Friday, September 20, 2013 12:05:17 PM UTC-5, Greg Sutcliffe wrote: Is this puppet3? As I recall, in puppet3, the master makes a separate call to the enc to determine the environment the should authoritatively be in. Once that's established, it makes a second call to get the classes and parameters. Not exactly, but that may well be the right track. It would be pointless for the master to run the ENC more than once for catalog compilation, for it would have no reason to expect that the ENC's output would change. HOWEVER, the master's file server may need to run the ENC again to determine the environment from which to serve 'source'd files.

[Puppet Users] Re: Using Virtual Resources and create_resource combination
ok I found a workaround to my problem. I updated the network module
(https://forge.puppetlabs.com/razorsedge/network) so that it is now
accepting a label as the name rather than interface (eth0 etc). In this way
I can provide a unique name and get away with assigning same name leading
to error. then I introduced a new parameter to module to accept interface.
For example my data now updated as follows.
/etc/puppet/hieradata/admin1.json
{
networks:{
admin1-admin:{
interface:eth0,
ipaddress:192.168.1.1,
netmask:255.255.255.0
}
}
}
But I still like to know is it possible to use the create_resources and
virtual resources together where I need to pass hieradata also.
Thanks,
CD
