puppettop? How can I see what puppet is doing? - monitoring

I'm getting started with Puppet. I added some lines to a manifest and when running Puppet now it's been at 100% cpu for a very longtime. Is there a good way to see what puppet is actually doing? puppettop?
top gives me this, which is quite useless:

I want to find only the average dload values
My current code is :-
local file = io.open(path, "rb")
if not file then return nil end
local lines = {}
local words = {}
for line in io.lines(path) do
for word in line:gmatch("%w+") do
table.insert(words, word)
end
table.insert(lines, words)
end
file:close()
return words;
But this code is giving me indexes , and all words as values. I am not able to find specific value for average dload
I am new to lua , any help is much appreciated

I think you are almost there. This is how I would do that. col will hold the number of the column for which we are gathering the output, such that you can separately get the stats for the different columns.
local file = io.open(path, "rb")
if not file then return nil end
local lines = {}
local stats = {}
local col
for line in io.lines(path) do
col = 0
for word in line:gmatch("%w+") do
if word then
col = col + 1
stats[col] = stats[col] or { }
stats[col][word] = (stats[col][word] or 0) + 1
end
end
table.insert(lines, words)
end
file:close()
When I do now the following:
for col, val in ipairs(stats) do
for word, count in pairs(val) do
print("Col=", col, "word=", word, "count=",count)
end
end
I get the following output:
Col= 1 word= 39k count= 1
Col= 1 word= 0 count= 13
Col= 1 word= 11 count= 5
Col= 1 word= 12 count= 4
Col= 2 word= 0 count= 9
Col= 2 word= 9539k count= 13
Col= 2 word= 11 count= 1
Col= 3 word= 12 count= 4
...etc.

Jenkins process high cpu usage 800%.

I have installed jenkins version 1.614 on ubuntu 12.04 with configuration - 32 GB ram, 2 TB hdd and 8 CPU cores. Currently Jenkins has 594 jobs added.
In normal condition when no job is running cpu usage is 0% but When I start any job build cpu usage suddenly reaches 700-800%.
Following are the stats for cpu usage.

I have also deleted job builds older than 30 days and current running job build is also small job, Still cpu usage is very high.

Example of Recording from the Mic and processing the (PCM?) file

I need to record sounds from the iPhone mic and process the samples in my Swift app. I would really appreciate an example to follow.
These Recording settings
let recordSettings:[String : AnyObject] = [
AVFormatIDKey: NSNumber(unsignedInt:kAudioFormatLinearPCM),
//AVEncoderAudioQualityKey : AVAudioQuality.Max.rawValue,
// AVEncoderBitRateKey : 320000,
AVNumberOfChannelsKey: 1,
AVSampleRateKey : 8000.0,
AVLinearPCMBitDepthKey: 16,
AVLinearPCMIsBigEndianKey: "true",
AVLinearPCMIsFloatKey: "false"
]
produce the following bytes
99 97 102 102 0 1 0 0 100 101 115 99 0 0 0 0 0 0 0 32 64 191 64 0 0 0 0 0 108 112 99 109 0 0 0 2 0 0 0 2 0 0 0 1 0 0 0 1 0 0 0 16 102 114 101 101 0 0 0 0 0 0 15 176 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
Which looks fishy maybe it's a double still?

I already created an example for something like that. It gets the data from the microphone, does a Fast-Fourier-Transform on it to find the frequencies and displays them in the view. It's done for OSX, but it should also work on iOS:
