Ghost Host Issue

[Sandeep_Patil]

We are facing Ghost Host Issue, tried below mention solution but issue not resolved.

1) Check with steps mention in http://support.nagios.com/wiki/index.ph ... t_Hosts.29

2) Delete entry form /prefdata

3) Go to CCM -> Write -> Verify -> Delete -> Restart Nagios

Need your help to remove ghost host, due to ghost host we are unable to add Hosts and Services.

Are you sure that you removed the host from the database? Can you see it in the CCM? Do you see any config errors, when you run the Write Config Tool?

CCM->Tools->Write Config Files->Write->Verify

Have you tried running the Write Config Tool in the following order?

CCM->Tools->Write Config Files->Delete->Write->Verify->Apply Configuration

Do you have multiple nagios processes running? What is the output of the following command?

Code: Select all

ps -ef | grep bin/nagios

[Sandeep_Patil]

Can you look for that configuration error in the CCM?

[Sandeep_Patil]

we are not facing error after applying below mention CCM tool order.

CCM->Tools->Write Config Files->Delete->Write->Verify->Apply Configuration

What about "ps -ef | grep bin/nagios" out put ?

You have a lot of workers, but you didn't have multiple processes running, which is what I was looking for.

The red frame is showing a configuration error. Can you investigate that?

[Sandeep_Patil]

Yes investigated red frame error, but www.universalsompo.com.cfg not found in "/usr/local/nagios/etc/services/"
