### Get Logwatch detail level (default to 0)
my $detailLevel = $ENV{'LOGWATCH_DETAIL_LEVEL'} || 0;


### Declare variables
my $summaryErr;
my $summaryWarn;
my $summarySuccess;

my %reportHash = ();
my $key;


### Minimal detail level: provide summary data only
if ($detailLevel == 0) {
    ### process logfile and summarize message types
    while (defined(my $ThisLine = <STDIN>)) {
        if ($ThisLine =~ /\-- \[ERROR\] /) {
            $summaryErr++;
        }
        elsif ($ThisLine =~ /\-- \[WARNING\] /) {
            $summaryWarn++;
        }
        elsif ($ThisLine =~ /All processes completed/) {
            $summarySuccess++;
        }
    }

    ### fill hash table with headings and summary counts
    if ($summarySuccess > 0) {
        $reportHash{"All processes successfully completed"} = $summarySuccess;
    }
    if ($summaryWarn > 0) {
        $reportHash{"Warnings issued"} = $summaryWarn;
    }
    if ($summaryErr > 0) {
        $reportHash{"Errors encountered"} = $summaryErr;
    }

    ### print hash table
    foreach $key (sort keys %reportHash) {
        print "$key: $reportHash{$key}\n";
    }
}
### Levels 1-4 provide the actual error, warning and success messages instead
### of a summary count
elsif ($detailLevel >= 1 && $detailLevel <= 4) {
    while (defined(my $ThisLine = <STDIN>)) {
        if ($ThisLine =~ /\-- \[ERROR\] /) {
            print $ThisLine;
        }
        elsif ($ThisLine =~ /\-- \[WARNING\] /) {
            print $ThisLine;
        }
        elsif ($ThisLine =~ /\-- \[SUCCESS\] /) {
            print $ThisLine;
        }
    }
}
### Level 5 is similiar to levels 1-4 except it also reports informational
### messages such as the location of script created files, variable checks,
### etc. This is useful when verifying the script's operation.
elsif ($detailLevel == 5) {
    while (defined(my $ThisLine = <STDIN>)) {
        if ($ThisLine =~ /\-- \[ERROR\] /) {
            print $ThisLine;
        }
        elsif ($ThisLine =~ /\-- \[WARNING\] /) {
            print $ThisLine;
        }
        elsif ($ThisLine =~ /\-- \[SUCCESS\] /) {
            print $ThisLine;
        }
        elsif ($ThisLine =~ /\-- \[INFO\] /) {
            print $ThisLine;
        }
    }
}
### Any level above 5 will echo the entire log including the debugging notes
### within the script meant for troubleshooting.  Using this level of detail
### should only be done if you cannot view the actual log file directly for
### whatever reason.  The actual log file is colour-coded for easier debugging.
elsif ($detailLevel > 5) {
    while (defined(my $ThisLine = <STDIN>)) {
        print $ThisLine;
    }
}



### Exit gracefully
exit (0);
