barman plugin

[amicohen1]

hi,
whenver i use barman plugin, the NRPE respond with "NRPE: Unable to read output".

i was adding nagios to sudo without password for this script, and when i execute the command in command line (from root), it apears fine:
sudo /usr/lib/nagios/plugins/check-barman.rb -a backups_available -s angus -w 5 -c 6.
same thing happen also when i do it with: barman check --nagios .....
any idea ?
Thanks,
Ami

What happens if you execute it as the nagios user (no sudo)?

Also - what are the permissions on the file? ls -l check-barman.rb

[amicohen1]

actually i moved to work directly on barman (barman check --nagios angus) and still same thing happening, also without sudo (when executing it directly with sudo account, its working fine)

sudo -U nagios -l
Matching Defaults entries for nagios on localhost:
env_reset, mail_badpass, secure_path=/usr/local/sbin\:/usr/local/bin\:/usr/sbin\:/usr/bin\:/sbin\:/bin

User nagios may run the following commands on localhost:
(root) NOPASSWD: /usr/lib/nagios/plugins/check-barman.rb, /usr/bin/barman
(ALL : ALL) ALL


-rwxr-xr-x 1 root root 851 Nov 16 11:51 /usr/bin/barman*

Can you post how the command is setup in the nrpe,cfg file on the remote sysrem and how you are running the check on the Nagios system?

Does adding the line below to sudors help?

Code: Select all

nagios ALL=NOPASSWD: /usr/lib/nagios/plugins/check-barman.rb *

[amicohen1]

i tryed both options:
command[check_barman]=sudo /usr/bin/barman check --nagios angus
and
command[check_barman]=sudo /usr/lib/nagios/plugins/check-barman.rb -a backups_available -s angus -w 5 -c 6

(and also without the sudo).

i also tried the advise of adding * to sudoers file (nagios ALL=NOPASSWD:/usr/bin/barman * ), and same result

[tgriep]

On your remote system that the check is installed, can you run the following and post the output here?

Code: Select all

/usr/lib/nagios/plugins/check-barman.rb -a backups_available -s angus -w 5 -c 6
su nagios
/usr/lib/nagios/plugins/check-barman.rb -a backups_available -s angus -w 5 -c 6

Thanks

sorry for late response: when i logged in as root i get the following:

/usr/lib/nagios/plugins/check-barman.rb -a backups_available -s angus -w 5 -c 6

1 backups available


su -l nagios -c '/usr/lib/nagios/plugins/check-barman.rb -a backups_available -s angus -w 5 -c 6'

no output

[amicohen1]

found the problem...
nagios ALL=(root) NOPASSWD:/usr/bin/barman need to apear after the definitions of the groups. as described in: http://askubuntu.com/questions/504652/a ... oesnt-work

thanks alot for those who were trying to assist!!!
