I might be wrong but I see a flaw in your contrôl.
Your contrôl is based on this check :
$INCEPT being the value of your watched log_file. What happens if the process who feeds your log file crashs? Or if the application fucks up and don't have anything else to feed to your log_file?
Your log file will still be greater than 0 and your script won't detect it.
I was thinking of a similar script for work with the same check on a log file (ls -lrt | awk '{print $5}' )
but instead of checking the current value, I compare the new value to the previous one (just by redirecting old value to random file > old_value) and if it's equal to the previous value => restart.
Something like this
Might need a little tweaking or add a count so that it only restarts the process after 2 failed checks or something.

SCRIPTMGR(1)SCRIPTMGR(1)NAME
scriptmgr - utility for controlling other skytools scripts.
SYNOPSIS
scriptmgr.py [switches] config.ini <command> [-a | job_name ... ]
DESCRIPTION
scriptmgr is used to manage several scripts together. It discovers potential jobs based on config file glob expression. From config file it
gets both job_name and service type (that is the main section name eg [cube_dispatcher]). For each service type there is subsection in the
config how to handle it. Unknown services are ignored.
COMMANDS
status
scriptmgr config.ini status
Show status for all known jobs.
start
scriptmgr config.ini start -a
scriptmgr config.ini start job_name1 job_name2 ...
launch script(s) that are not running.
stop
scriptmgr config.ini stop -a
scriptmgr config.ini stop job_name1 job_name2 ...
stop script(s) that are running.
restart
scriptmgr config.ini restart -a
scriptmgr config.ini restart job_name1 job_name2 ...
restart scripts.
reload
scriptmgr config.ini reload -a
scriptmgr config.ini reload job_name1 job_name2 ...
Send SIGHUP to scripts that are running.
CONFIG
Common configuration parameters
job_name
Name for particulat job the script does. Script will log under this name to logdb/logserver. The name is also used as default for PgQ
consumer name. It should be unique.
pidfile

logfile

loop_delay
If continuisly running process, how long to sleep after each work loop, in seconds. Default: 1.
connection_lifetime
Close and reconnect older database connections.
log_count
Number of log files to keep. Default: 3
log_size
Max size for one log file. File is rotated if max size is reached. Default: 10485760 (10M)
use_skylog
If set, search for [./skylog.ini, ~/.skylog.ini, /etc/skylog.ini]. If found then the file is used as config file for Pythons logging
module. It allows setting up fully customizable logging setup.

If this service should be ignored.
Example config file
[scriptmgr]
job_name = scriptmgr_livesrv
logfile = ~/log/%(job_name)s.log
pidfile = ~/pid/%(job_name)s.pid
config_list = ~/scripts/conf/*.ini
# defaults for all service sections
[DEFAULT]
cwd = ~/scripts
[table_dispatcher]
script = table_dispatcher.py
args = -v
[cube_dispatcher]
script = python2.4 cube_dispatcher.py

-h, --help

-q, --quiet
make program silent
-v, --verbose

-d, --daemon
make program go background
Following switches are used to control already running process. The pidfile is read from config then signal is sent to process id specified
there.
-r, --reload
reload config (send SIGHUP)
-s, --stop
stop program safely (send SIGINT)
-k, --kill
kill program immidiately (send SIGTERM)
Options specific to scriptmgr:
