Nagios® Core™ Version 4.4.2 error

[tjapke]

Hello i have a problem with the Nagios® Core™ Version 4.4.2 August 16, 2018 .

The following error appears:
---------------------------------------------------
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 https://www.nagios.org.
---------------------------------------
i have a the moment not the idea to resolv this problem.

First is the nagios service running?

Code: Select all

ps -ef|grep nagios

Second, is the status.dat file in the nagios var directory readable by the nagios user/group?

Is apache user part of the nagios group?

Code: Select all

grep nag /etc/group
