I would like to know of any commands or utilities there are to check the runtime footprint of application in vxworks (target board).
And I'd also like to know how to find the CPU usage of target board.
Not quite sure what you mean by "runtime footprint", but the ti command will show you the stack usage for a particular task:
-> ti tNet0

For cpu usage, enable INCLUDE_SPY in your BSP and execute spy to start the display of the cpu usage:
->spy

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.

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.
I have linux application on embedded linux that uses pthread library. From time to time pthread "manager" thread get signal 33 and crashed.
How do I know who is sending the signal?
Strace log:

Signal 33 is used internally by the pthreads library (it is referred to as SIGSETXID, and is raised by the library for every thread whenever one of the uids or gids of the process are changed).
It should not cause a thread to crash. Why do you believe this signal is responsible?
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:
