Nagios Support Forum

I am getting following error message when trying to login to NagiosXI.
DB Connect Error [nagiosxi]: Database connection failed DB Connect Error [nagiosxi]: Database connection failed
CPU jumped to 80x normal usage, npcd process leading the pack.

Tried repairing the database as per http://assets.nagios.com/downloads/nagi ... tabase.pdf but no go. I didn't get SQL error message after I started Nagios again so I didn't proceed further.

Centos 6.4x64 (virtual), Nagios (latest one forgot the version and can't retrieve it now as it's down), MySQL (mysql-server-5.1.69-1.el6_4.x86_64)

Can you run the following and try accessing the interface again?:

Thanks for help slansing, that was it. It looks like postrgresql was stoppped. Does nagios uses two different db servers (mysql, postgresql)?

That is correct. MySQL is used for object data, postgres is used for user data.

thank you guys

I'll close this as resolved!
