Actually I have one more bug:


Any idea why we see the same DIFF_DATE syntax error in expr for this section:

Code:
while IFS=, read -r INSTANCE SESS_COUNT INSERT_TIME

DATE_DIFF=`expr ${CHECK_DATE_1} - ${INSERT_TIME}`

do

if  [[ ${SESS_COUNT} -eq 0 ]]
then
echo Send Normal Alert

elif [[ ${DATE_DIFF} -gt 300 && ${DATE_DIFF} -lt 600 ]]
then
echo Critical Alert: ${DATE_DIFF}

elif [[ ${DATE_DIFF} -gt 600 ]]
then
echo Major Alert: ${DATE_DIFF} ${INSTANCE}

fi
done < ${FILE1}


Code:
+ IFS=,
+ read -r INSTANCE SESS_COUNT INSERT_TIME
++ expr 1525273451 -
expr: syntax error
+ DATE_DIFF=


It seems to another read of the file at the end of the script even though there are no extra lines before the data or after the data in the file:

Code:
lit-dbracm01-p002:/home/oracle>cat /tmp/longrunmon.out
testinst,0,1525186184
testinst-2,0,1525186184

locale::codes::langfam

Locale::Codes::LangFam(3)				User Contributed Perl Documentation				 Locale::Codes::LangFam(3)

NAME

       Locale::Codes::LangFam - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangFam;

	  $lext = code2langfam('apa');		       # $lext gets 'Apache languages'
	  $code = langfam2code('Apache languages');    # $code gets 'apa'

	  @codes   = all_langfam_codes();
	  @names   = all_langfam_names();

DESCRIPTION

       The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in
       ISO 639-5.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5
       language family codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a
       constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lext = code2langfam('apa','alpha');
	  $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages.

	   This is the default code set.

ROUTINES

       code2langfam ( CODE [,CODESET] )
       langfam2code ( NAME [,CODESET] )
       langfam_code2code ( CODE ,CODESET ,CODESET2 )
       all_langfam_codes ( [CODESET] )
       all_langfam_names ( [CODESET] )
       Locale::Codes::LangFam::rename_langfam  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangFam::add_langfam  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangFam::delete_langfam  ( CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangFam::delete_langfam_alias  ( NAME )
       Locale::Codes::LangFam::rename_langfam_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::delete_langfam_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
