This is one of the first custom facts I wrote, you would likely want to improve
on it based on the guide. However it has worked for us for a few years now.
Enjoy?
This lives in inventory/lib/facter/hpsrl.rb.
if FileTest.exists?("/usr/sbin/dmidecode")
# Add remove things to query here
query = {
'HP ProLiant System/Rack Locator' => [
'Rack Name:',
'Enclosure Name:',
'Enclosure Model:',
'Enclosure Serial:',
'Enclosure Bays:',
'Server Bay:',
'Bays Filled:',
]
}
# Run dmidecode only once
output=%x{/usr/sbin/dmidecode 2>/dev/null}
query.each_pair do |key,v|
v.each do |value|
output.split("Handle").each do |line|
if line =~ /#{key}/ and line =~ /#{value} (\w.*)\n*./
result = $1
result = result.gsub(/ *$/, '').gsub(/^ */, '')
Facter.add(value.chomp(':').gsub(/ /, '_')) do
confine :kernel => :linux
setcode do
result
end
end
end
end
end
end
end
