support for setting spawn limit via puppet

[cabecada]

we have hit the bottleneck of too many checks (JIT) from a single server leading to issues addressed by sensu/sensu#1265. i know there are other workarounds to deal with this, but since this is public(?) config, i guess it should be configurable via puppet.

but it seems this is not yet configurable via puppet.
any plans to include this configurable option ?

Thanks @cabecada for reporting this!

@agoddard @cwjohnston I cannot find any documentation for this option on our site. Could you point me in the right direction?

Which file should this go in?

[cwjohnston]

You're right there's no documentation for this setting presently. sensu/sensu-docs#451 is tracking that need. Because this modifies the concurrency of both sensu-server pipe handler execution and sensu-client check execution (when running on same system), I recommend using /etc/sensu/conf.d/spawn.json

This is what i tried but i guess this has to go via providers and types?
though hardcoded, but it can be parameterized.

class profiles::sensu::spawn {

  $config = {
    "sensu" => {
      "spawn" => {
        "limit" => 20
      }
    }
  }

  file { "/etc/sensu/conf.d/spawn.json":
    mode    => '0644',
    owner   => 'sensu',
    group   => 'sensu',
    require => Package['sensu'],
    content => inline_template(
      '<%= require "json"; (JSON.pretty_generate @config) + $/ %>'
    ),
    notify  => Class['sensu::client::service']
  }
}
