not sure if this is the "best" way to do this, but, taking from a different
module I have:
hiera yaml:
snmp_filesystems:
root: {
mountpoint: '/',
threshold: '10%'
}
snmp_collector:
test: {
ip: '1.2.3.4',
group: 'readonly',
community: 'somecommunity'
}
class:
class snmp::params(
filesystems = hiera(snmp_filesystems, undef),
collector = hiera(snmp_collector, undef)
{
#…
}
template:
<%
collector = scope.lookupvar('snmp::params::collector')
filesystems = scope.lookupvar('snmp::params::filesystems')
-%>
<% collector.each_pair do |key, hash| -%>
group <%=hash['group']-%> v2c <%=key%>
<%end-%>
# Filesystem monitoring enabled
<% filesystems.each_pair do |key, hash| -%>
# <%=key%>
disk <%=hash['mountpoint']-%> <%=hash['threshold']%>
<%end-%>
does that help at all?
