nagios restart error

[mohiddins]

Hi All,

Recently my nagios got crashed as im unable to browse are view any host entries & other information getting below error

Whoops!

Error: Could not read host and service status information!

The most common cause of this error message (especially for new users), is the fact that Nagios is not actually running. If Nagios is indeed not running, this is a normal error message. It simply indicates that the CGIs could not obtain the current status of hosts and services that are being monitored. If you've just installed things, make sure you read the documentation on starting Nagios.

Some other things you should check in order to resolve this error include:

Check the Nagios log file for messages relating to startup or status data errors.
Always verify configuration options using the -v command-line option before starting or restarting Nagios!
Make sure you read the documentation on installing, configuring and running Nagios thoroughly before continuing. If all else fails, try sending a message to one of the mailing lists. More information can be found at http://www.nagios.org.

Can any one help me out from this..

Please post the output of the following:

Code: Select all

ls -l /usr/local/nagios/var/status.dat
ls -l /usr/local/nagios/var/retention.dat

Also, if you stop nagios, does the status.dat file from above get removed? If not, manually delete the status.dat file (it will get rebuilt) and start nagios.
