Nagios Support Forum

Hi Team,

While access the GUI web console ,i am getting the ERROR - " DB Connect Error [nagiosxi]: database connection failed ".

I already tried to start / stop the mysqld,but it didn't work.

Please provide us the solution.

Thanks & Regards

I moved this to the XI forum as this is not a core question. Anyway, when you say that you restarted mysql and it did not work, what exactly do you mean? Was the database not started, or did the errors not change in XI? Have you altered the mysql passwords at all?

Hi,

We are able to login on Nagios web console after server reboot,however i am not able to view the Service Status "No matching services found".
I am able to view the Host details.

Could you please help on this to get the fix.

You may be experiencing crashed tables depending on how you rebooted your server. Lets run the database repair script and see if you have your services back in their tables on the web interface. Also, run the following commands and share the output: http://assets.nagios.com/downloads/nagi ... tabase.pdf
