我写了一个自定义事实,它返回一个逗号分隔的列表addr:port
,如下所示:
sb_intl_conn => sbcms-t:22,sbsql05-wvuk-inst5:1434,sborc07-uk-t:1533,..,..,..
字符串中的元素数量因节点而异。我需要对它们中的每一个进行 Nagios tcp-port-check。我认为sb_intl_conn.split(",")
会将这个字符串变成一个数组,然后我如何迭代它来做这样的事情?
@@nagios_service { "check_stat_${::fqdn}_${addr}_${port}":
use => 'generic-service',
check_command => "remote-nrpe-tcp-check!${addr}!${port}",
service_description => "V2::CON: ${addr} [Palms]",
display_name => "Connection check: ${addr}:${port}",
servicegroups => 'batch-worker',
hostgroup_name => 'batch-job',
}
任何帮助将不胜感激。干杯!!

我与模拟器 iamauser 的建议联系在一起,但还没有完全理解它。这就是我所做的:在我的 foo.pp 中:
class test::foo {
define bar {
$var1 = inline_template("<%= scope.lookupvar($name).split(':').first.to_s.chomp %>")
$var2 = inline_template("<%= scope.lookupvar($name).split(':').last.to_s.chomp %>")
notify {"${var1}_${var2}": }
}
}
然后在我的 node.pp 中:
$ifs = ['abc.com:80','xyz.co.uk:1512']
test::foo::bar {$ifs:}
这会在节点上引发这些错误:
err: Could not retrieve catalog from remote server: Error 400 on SERVER: Failed to parse inline template: Could not find value for 'abc' in 65 at /etc/puppet/services/test/manifests/foo.pp:4 on node jobserver-01.local.cloud.uk
warning: Not using cache on failed catalog
err: Could not retrieve catalog; skipping run
不明白我做错了什么。为什么是Could not find value for 'abc'
;不是abc.com
吗?任何的想法??干杯!!

我最终使用了 heira 并决定尝试最初的“哈希数组”想法并且在实现时遇到了一些问题:
这就是我在 heira 中所拥有的:
hiera -d -c /etc/puppet/hiera.yaml nag_chk m_env=talend s_env=local
[ ... ]
DEBUG: Thu Mar 21 12:28:02 +0000 2013: Got answer for key nagi_chk, final answer
DEBUG: Thu Mar 21 12:28:02 +0000 2013: Answer after outer loop = archimedes-db-02.svc.ft.com:1521 ftftp01-uvln-uk-p:22 www.google.com:80 ftaps01-lvpr-uk-local:8080
archimedes-db-02:1521 ftftp01-uvln-uk-p:22 google.com:80
然后,在我的 foo.pp
class test::foo {
define bar2 () {
$var1 = $name['addr']
$var2 = $name['port']
notify {"*** ${var1}_${var2} *********": }
}
}
和我的node.pp:
$array_chk = hiera('nag_chk')
$urls = inline_template("<%= '$array_chk'.split(' ').map{|kv| v1,v2 = kv.split(':'); {'addr' => v1, 'port' => v2}} -%>")
test::foo::bar2 {$urls:}
和往常一样,我收到一个错误:
错误:无法从远程服务器检索目录:服务器上的错误 400:在节点 talend 上的 /etc/puppet/services/talend/talend/manifests/foo.pp:10 上使用 0 访问名称时,名称不是哈希或数组- jobserver-01.local.cloud.ft.com 警告:未在失败的目录上使用缓存错误:无法检索目录;跳过跑步
我做错了什么?据我所见,irb
控制台中正确格式的“哈希数组”:
irb(main):001:0> STRING = "archimedes-db-02:1521 ftftp01-uvln-uk-p:22 google.com:80"
=> "archimedes-db-02:1521 ftftp01-uvln-uk-p:22 google.com:80"
irb(main):003:0>
irb(main):002:0> STRING.split(' ').map{|kv| v1,v2 = kv.split(':'); {'addr' => v1, 'port' => v2}}
=> [{"addr"=>"archimedes-db-02", "port"=>"1521"}, {"addr"=>"ftftp01-uvln-uk-p", "port"=>"22"}, {"addr"=>"google.com", "port"=>"80"}]
任何进一步的想法?干杯!!
