Problem with os::linux::local::plugin Regex --exclude-mountpoint doesn't works

[dailyline]

Hello,

We use centreon plugin to check datstorage space on remote linux. I want to exlude more than one folder. We use 'os::linux::local::plugin' mode 'storage'. A single exclusion works I have problem with the regexp of "--exclude-mountpoint 'Exclude filesystem mount point (regexp can be used)" I try lots of things --exclude-mountpoint '(/boot|/dev)' --exclude-mountpoint '((/boot|/dev)$$)' "--exclude-mountpoint '(/boot|/dev)"

error is syntax error near unexpected token `(' or Receive header underflow - only 0 bytes received (4 expected). _

full syntax /usr/lib64/nagios/plugins/check_centreon_nrpe3 -u -H tatayoyo -p 5666 --cipher-list ADH --ssl-version=TLSv1.2 -t 120 -c check_centreon_plugins -a 'os::linux::local::plugin' 'storage --units 'B' --free --warning-usage 1400MB: --critical-usage 900MB: --exclude-mountpoint '^(?!(/boot|/dev)) '

It works for me:

perl centreon_plugins.pl --plugin=os/linux/local/plugin.pm --mode=storage --exclude-mountpoint='' --verbose

Be careful in NRPE. You cannot use the character !. So you cannot do negative regexp and that's why i have added the option --exclude-mounpoint.

Hello, Thanks for your answer. I just tested like you did and it actually works. I ran a test with my args with your command line and the result is ok ./centreon_plugins.pl --plugin=os/linux/local/plugin.pm --mode=storage --exclude-mountpoint='(/var|/boot/efi)' --units=B --free --warning-usage=1400MB: --critical-usage=900MB: --verbose It's not works when I exclude / exemple (/[boot/efi) It's return "UNKNOWN: No storage found (filters or command issue)"

My initial problem seems to come to my syntax when I use check_centreon_nrpe3, I will investigate. Thanks again for you assistance.

thanks for your feedback. i close it. Your regexp (/[boot/efi) cannot match (--> [)
