Please provide us the solution.

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?

Code: Select all

service mysqld status
service postgresql status

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:

Code: Select all

df -i

Code: Select all

df -h

As previously asked, did you alter the mysql or postgres passwords at all? Run the command below as well please and return the output.

Code: Select all

tail -n 50 /var/log/httpd/error_log
