but certain scripts which are expected to take a long time to let them go?
How to categorize them actually ?
To be on the safer side for these kind of problems; a safe and reliable approach would be to,
if possible make the process which needs to be monitored dump some [DEBUG] messages, [INFO] messages every 'n' time slice to an unique log file
With that it would be quite easy to track the status of the process by parsing the log file that is specific to each of the process that needs to be monitored.

NAME
strerr - receive error messages from the STREAMS log driver
SYNOPSIS
sys_admin_mail_name] logdir]
DESCRIPTION
receives error messages from the STREAMS log driver (strlog(7)) for addition to the STREAMS error log files mm-dd) in the STREAMS error
logger directory by default). When first called, creates the log file This is a daily log file, where mm indicates the month and dd indi-
cates the day of the logged messages. then appends error messages to the log file as they are received from the STREAMS log driver.
STREAMS error log messages have the following format:
seq time tick pri ind mod sub text
Components are interpreted as follows:
seq Error event sequence number.
time Time the message was sent expressed in hh:mm:ss.
tick Time the message was sent expressed in machine ticks since the last boot.
pri Error priority level as defined by the STREAMS driver or module that originates the messages.
ind Can be any combination of the following three message indicators:
The message has also been saved in the trace log.
The message signaled a fatal error.
The message has also been mailed to the system administrator.
mod Module identification number of the error message source.
sub Subidentification number of the error message source.
text Error message text.
runs continuously until terminated by the user.
Options
recognizes the following options and command-line arguments:
Specify the user's mail name for sending mail messages.
Mail is sent to the system administrator by default.
Specify the directory to contain the error log file.
Default is
WARNINGS
Only one process can open the STREAMS log driver at a time. This restriction is intended to maximize performance.
The STREAMS error logging mechanism works best when it is not overused. can degrade STREAMS performance by affecting the response,
throughput, and other behaviors of the drivers and modules that invoke it. also fails to capture messages if drivers and modules generate
messages at a higher rate than its optimum read rate. If there are missing sequence numbers among the messages in a log file, messages
have been lost.
