hamann / check-barman Goto Github PK

Hello,

I have an issue with nrpe & check-barman, I don't understand where is my problem.
I modified /etc/sudoers adding this :
Defaults:nagios !requiretty
nagios ALL=(ALL) NOPASSWD:/usr/lib64/nagios/plugins/check-barman/check-barman.rb

With nagios user, when I execute the command, it works :
-sh-4.1$ whoami
nagios
-sh-4.1$ sudo /usr/lib64/nagios/plugins/check-barman/check-barman.rb -a pg -s KBILL-SAP -h /opt/data/MSA/barman
PG connection ok
-sh-4.1$ rvmsudo /usr/lib64/nagios/plugins/check-barman/check-barman.rb -a pg -s KBILL-SAP -h /opt/data/MSA/barman
PG connection ok

I configured nrpe file :
dont_blame_nrpe=1
allowed_hosts=X.X.X.X
command[check-barman]=/usr/local/rvm/bin/rvmsudo /usr/lib64/nagios/plugins/check-barman/check-barman.rb -a $ARG1$ -h /opt/data/MSA/barman -s $ARG2$ -w $ARG3$ -c $ARG4$
command[check_barman_pg]=sudo /usr/lib64/nagios/plugins/check-barman/check-barman.rb -a pg -s KBILL-SAP -h /opt/data/MSA/barman

With other nrpe commands, it works but not with the barman plugin. I have this error :
NRPE: Unable to read output

Did you encounter this error?

Hello,

With the new barman version 1.3.0, the result of the command "barman list-backup KBILL-SAP" returns :

KBILL-SAP 20140422T220001 - Wed Apr 23 10:00:53 2014 - Size: 124.5 GiB - WAL Size: 4.2 GiB (tablespaces: kbill_tbs:/opt/data/postgres)
KBILL-SAP 20140417T220002 - Thu Apr 17 22:38:50 2014 - Size: 120.1 GiB - WAL Size: 4.0 GiB (tablespaces: kbill_tbs:/opt/data/postgres)

The command "./check-barman.rb -a last_wal_received -s KBILL-SAP -w 300 -c 600" returns an error :

/usr/local/rvm/gems/ruby-2.1.0/gems/rbarman-0.0.12/lib/rbarman/cli_command.rb:269:in size_in_bytes': unit not one of B|KiB|MiB|GiB|TiB (ArgumentError) from /usr/local/rvm/gems/ruby-2.1.0/gems/rbarman-0.0.12/lib/rbarman/cli_command.rb:217:inblock in parse_backup_list'

from ./check-barman.rb:78:in check_last_wal_received' from ./check-barman.rb:202:in

The issue is in your match of these lines in your lib rbarman/cli_command.rb, line 215 :
sizematch = l.match(/.+Size:\s(.+)\s(.+)\s-.+Size:\s(.+)\s(.+)/)

You need to modify it for not to match " (tablespaces: kbill_tbs:/opt/data/postgres)" at the end of the result. You can change it by this match :
sizematch = l.match(/.+Size:\s(.+)\s(.+)\s-.+Size:\s(.+)\s(.+)\s(/)

when i am going to execute

./check-barman.rb -a last_wal_received -s postgresdb -w 300 -c 600

i am getting error

I am using pgbarman version 1.4.1 in ubuntu 14.04.

Hi

I am using redhat , and I assume it shuold be installed on barman server where we a nagios agent is installed already ?

thank you

$ ./check-barman.rb -a backups_available -s test1 -w 5 -c 6
"4 backups available"

check number of backups and set warning if number of backups is > 5 or set critical if number of backups is > 6

Shouldn't the ">" (larger then) be "<" (smaller then) in the sentence above explaining the avail backups and warning level?

So, give a warning if the number of available backups is "smaller then" 5?

Is it because new barman version output changed?

When I call
/check-barman.rb -a last_wal -s <HOST> -w 300 -c 600
I get this error:
.../check-barman.rb:95:in check_last_wal_received': undefined method created' for nil:NilClass (NoMethodError)

Apparently the object latest.wal_files.last does not exist.

Hi,

I've encountered an error with check-barman for the actions last_wal and mssing_wal, that is caused by a WAL history file. The history file is created when the timeline changes. In my case this always occurs after performing a failover in a master/slave cluster managed by crm.

./check-barman.rb -a last_wal -s mypgcluster -w 5 -c 10

The check command is causing the following error:

/var/lib/gems/1.9.1/gems/rbarman-0.0.15/lib/rbarman/wal_file.rb:109:in parse': name has to be exactly 24 chars (RBarman::InvalidWalFileNameError) from /var/lib/gems/1.9.1/gems/rbarman-0.0.15/lib/rbarman/cli_command.rb:196:inblock in parse_wal_files_list'

Hello,

I have an error when I try to execute the check with the user nagios and sudo :

-sh-4.1$ whoami
nagios
-sh-4.1$ sudo /usr/lib64/nagios/plugins/check-barman/check-barman.rb -a pg -h /opt/data/MSA/barman -s KBILL-SAP
/usr/lib64/nagios/plugins/check-barman/check-barman.rb:26:in `require': no such file to load -- rbarman (LoadError)
from /usr/lib64/nagios/plugins/check-barman/check-barman.rb:26

However, I have the rbarman gem installed :

-sh-4.1$ gem list rbarman

*** LOCAL GEMS ***

rbarman (0.0.13, 0.0.12)

And in sudoers file, I followed your advice and I added these lines :

Defaults:nagios !requiretty
nagios ALL=NOPASSWD: /usr/lib64/nagios/plugins/check-barman/check-barman.rb

And when I list gem with the command sudo, I also add rbarman gem :

-sh-4.1$ sudo gem list rbarman

*** LOCAL GEMS ***

rbarman (0.0.13, 0.0.12)

Isn't there something missing in your documentation to use check-barman with sudo command and nagios user?

I dont know why i have this return..
Effectivly i have a oldest failed backup but I think this a bug to parse returns ?

Greetings dev.

Recently updated our pgbarman installation to 1.6.0 and decided it was time to have some proper checks to verify the backups are proper.
However I am having some issues when running most of the check-barman actions. The psql setup is master --> slave replication with wal_level hot standby. Barman is running on the slave host, dumping to a locally mounted share.

whoami
barman

gem list rbarman
*** LOCAL GEMS ***
rbarman (0.0.15)

barman -v
1.6.0

The only check that works

./check-barman.rb -a pg -s main
PG connection ok

The checks that fails

./check-barman.rb -a ssh -s main
SSH connection failed!

Although SSH works according to barman itself

barman check main | grep ssh
ssh: OK (PostgreSQL server)

The ssh check I can live without. However the "good" checks spits out more fails which I interpret as being related to rbarman:
./check-barman.rb -a last_wal_received -s main -w 300 -c 600

Hi,
Thank you for the plugin. I have Barman 2.5 installed and I can successfully:
ssh [email protected] to mine postgresql 11 instance.

However I can't explain why the plugin fails to do the same:
barman@dev-gb-mgt-pg-01:/usr/lib/nagios/plugins/./check-barman.rb -a ssh -s dev-gb-gal-pg11-01
SSH connection failed!

I can however connect using action pg:
barman@dev-gb-mgt-pg-01:/usr/lib/nagios/plugins/./check-barman.rb -a pg -s dev-gb-gal-pg11-01
PG connection ok
Thank you.
