Nagios XI manual install
Centos6
32bit

So far I have read the posts on this error and tried the fixes and so far nothing seems to fix my issue. Also when i try to restart the postgresql service it fails to start. httpd restarts without issues though.

looking in /var/lib/pgsql/data/pg_log I am seeing over and over

ERROR: relation "xi_notifications" does not exist
STATEMENT: VACUUM ANALYZE xi_notifications;

and

Also I am straight command line on this install no GUI so I don't have gnome installed and am definitely not out of drive space I have 2x 1TB drives in raid -1 and have a lot of free space.
df output.

Code: Select all

[root@nagios ~]# df

Any ideas or anything I can do that might help trouble shoot this issue any kind of log file I should look in for errors?

I would start by restarting the server. Then from there I would run the following:

Code: Select all

cd /usr/local/nagiosxi/tools
./fix_postgres_sequences.sh

psql nagiosxi nagiosxi
vacuum;
vacuum analyze;
vacuum full;
\q

when trying to login to psql

Code: Select all

 psql nagiosxi nagiosxi
psql: could not connect to server: No such file or directory
        Is the server running locally and accepting
        connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

Hmm, is postgresql running at all?

Code: Select all

service postgresql restart

Posted: **Mon Dec 12, 2011 5:45 pm**

[root@nagios ~]# service postgresql restart
Stopping postgresql service: [ OK ]
Starting postgresql service: [FAILED]
[root@nagios ~]#

I don't know if this helps but in the /var/lib/pgsql/pgstartup.log

Code: Select all

Have you made any recent firewall changes or system changes recently that might point to a cause of this? Is this machine able to correctly resolve to localhost? It looks like it might not be...

32" to address: Name or service not known

I was having issues with FQDNS before and I tried to modify /etc/hosts changed it to

127.0.0.1 nagios.localdomain.com
::1

other than that nothing.

ok so I fixed the hosts/fqdn issue I was having which allows me to log back in and use nagios. But all of the hosts and services are gone from nagiosxi but everything seems to still be intact in nagioscore.

There's probably still a host name issue with mysql. Can you check the apache log for info:

Code: Select all

tail -f /var/log/httpd/error_log
