You don't need to cat into grep; grep can read the file on its own. Secondly, you can get by with one awk process rather than the whole pipeline, and you can assign the output to your variable rather than putting it into a file and having to read it back. If you do it that way, then you can compare directly. For example assuming kshell or bash:

Code:
danger=95
concern=80
cconn=$( awk '/DBX/ { split( $6, a, ":" ); c = a[2]; } END { print c }' /home/users/apps/alarms.log )
if (( cconn > danger ))
then
    echo "too many connections: $cconn"
else
    if (( cconn > concern ))
    then
        echo "large number of connections: $cconn"
    else
        echo "number of connections acceptable: $cconn"
    fi
fi

       writelog - add a entry to an INN log file.

SYNOPSIS

       writelog name text...

DESCRIPTION

       The writelog script is used to write a log entry or send it as mail.  The name parameter specifies the name of the log file where the entry
       should be written.  If it is the word ``mail'' then the entry is mailed to the  news  administrator,  <USER specified with --with-news-mas-
       ter at configure>.  The data that is written or sent consists of the text given on the command line, followed by standard input indented by
       four spaces.  Shlock(1) is used to avoid simultaneous updates to a single log file.
