Logic for alert scripts.

Hello,
In my system, I have implemented various alerts.
An example:

Code:

#!/bin/sh
BILL=bill@company.com
#GETS THE CURRENT NO OF SESSIONS OPENED IN ORACLE
SESSION_NO=`sqlplus -s ${TEST_USER} <<EOF
SET HEAD OFF
@/home/alerts/vlib/cur_session_no.sql
EOF`
 
#MANUALLY SET A THRESHOLD FOR THE SESSONS
SESSION_THRESHOLD=300
 
MAX_SESSIONS=`sqlplus -s ${TEST_USER} <<EOF
SET HEAD OFF
@/home/alerts/vlib/max_session_no.sql
EOF`
 
#IF NO OF SESSIONS EXCEED THE THRESHOLD SEND ME AN EMAIL
if [ $SESSION_NO -gt $SESSION_THRESHOLD ];
then
mailx -s "Number of processes in $ORACLE_SID Critical" $BILL <<EOF
Current No. of sessions in $ORACLE_SID: $SESSION_NO
Max No. of sessions are $MAX_SESSIONS
EOF
fi
exit

And these alerts are scheduled hourly.
My problem is that untill the problem is solved, it keeps sending the mail every hour.

Please give my any ideas (logic) on how I can have the alerts send to me once.
e.g use a flag that I will manually delete when the problem is resolved ?

Any ideas welcomed

Thank you in advance for your help.

I am thinking of:
1)Send the email once,
2)if the check (if [ $SESSION_NO -gt $SESSION_THRESHOLD ];
) does not change do not send the mail again.
3) When problem solved (check fails)
reenable the alert mechanism.

set_color

set_color(1)                                                           fish                                                           set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
