I figured out a workaround for this FlowDoh issue on my setup (first row is
empty):
If you get an error message like this when running the nfdump command:
Verify map id 5: ERROR: Expected 7 elements in map, but found 2!
Apparently this is normal.
Peter has already mentioned this about it:
"This is a known issue in the v5 module of nfdump-1.6.10. nfdump self
corrects this, therefore you can safely
ignore the message. This will be fixed a the next release."
As a temporary fix, I edited this file: /var/www/nfsen/plugins/flowdoh.php
Find: function flowdoh_output_table($csvdata, $offset, $settings) {
In this function add the following lines:
$csvdata = array_diff($csvdata, array('Verify map id 0: ERROR: Expected 7
elements in map, but found 2!'));
$csvdata = array_values($csvdata);
This got rid of the first element in the array (which was the error) and my
flowdoh page looks good now.
No more errors in my httpd logs either.
As I said I don't mess with PHP much, so maybe they'll find a better way.
Works for me though.
I'm liking FlowDoh.
