ps -elf AND grep for changes
Hoping theres something already out there like this.

I have a list of proccesses who's "ps -elf" (field 10) values I need to continuously monitor and if the values of field 10 start to signiciantly increase (double, triple) then do something. The field 10 is the "memory size" field.

(these are constant process names)
Code:
process1
process2
process3

Code:
foreach proccx ( process1 process2 process3 )
  initvar1,2,3 = ps -elf |grep $proccx |awk '{print $10}'
end

So now I would have 3 initial vars, (initvar1, initvar2, and initvar3)

Now enter some kind of a monitoring loop "for each" of the processes.
Code:
foreach proccx ( process1 process2 process3 )
  set curvar1,2,3 = ps -elf |grep process1 |awk {print $10}'
  if $curvar1 > $initvar1 * 2 , do something.
end

sleep 5
end


cshell or bash on solaris v10. The real problem I have found is variable "passing"

Running elf files

I have a few questions about elf files and how they are executed. When gcc compiles a elf file it creates an executable. Is this executable then run directly by the hardware or does the kernel get involved, interpret the elf file and place the asm code directly in memory. Cheers (0 Replies)

elf_end

ELF_END(3)						   BSD Library Functions Manual 						ELF_END(3)

NAME

     elf_end -- release an ELF descriptor

LIBRARY

     ELF Access Library (libelf, -lelf)

SYNOPSIS

     #include <libelf.h>

     int
     elf_end(Elf *elf);

DESCRIPTION

     Function elf_end() is used to release the resources associated with an ELF descriptor pointed to by argument elf.	This descriptor must have
     been allocated by a previous call to elf_begin(3) or elf_memory(3).  For programming convenience, a NULL value is permitted for argument elf.

     A call to elf_end() decrements the activation count for descriptor elf by one.  The resources associated with the descriptor are only
     released with its activation count goes to zero.

     Once function elf_end() returns zero, the ELF descriptor elf will no longer be valid and should not be used further.

RETURN VALUES

     Function elf_end() returns the current value of the ELF descriptor elf's activation count, or zero if argument elf was NULL.
