NagiosXI 5.5.9 - service dependency issue...

[vishfx]

Hi Nagios Team,

We are manually managing a bunch of Service Dependencies under static folder.

However, we noticed while deleting service using CCM, apply changes failed due to Service Dependency.
I understand this is the expected.

So we manually removed all the files using rm -f static/*
And followed the below steps :

1. CCM > Tools > Config File Management > Delete Files
2. CCM > Tools > Config File Management > Write Configs
3. CCM > Tools > Config File Management > Verify Files
4. All was good.

Now, we noticed that Service Dependency .cfg files were back under static/*
afaik, this is not expected.
And due to this we are unable to Delete any Host/Service & Apply Changes, it always error out with weird Dependency of Host/Service errors. It seems like these manually managed Service Dependency has somehow has got into the database and is causing issues.

Also, I do not see any Service Dependency under CCM->Host Dependencies or CCM->Service Dependencies

How can I check if there is any host/service dependency data in the DB ?
How to get rid of it ?

Kindly assist.

Regards,
Vish.

The items in the static directory will return if you go to apply config and it isn't sucessful because the system will restore the snapshot.

You can view host/service dependencies that are in the DB by navigating to CCM -> Host Dependencies and CCM -> Service Dependencies

Hi,


As I mentioned in initial post,

Service Dependency cfg files were managed manually under static directory.

CCM -> Host Dependencies and CCM -> Service Dependencies shows EMPTY.

So I am not sure how static directory will return if you go to apply config.

Kindly clarify.

Vish.

I was answering your question.

Now, there are backups created of the nagios/etc directory that contain everything that was in nagios/etc the last time the configuration was applied successfully, and if there is an unsuccessful Apply Configuration it will automatically roll back to the last known good configuration, which may include your files in the static directory.

I would recommend doing the following (and if possible prevent any coworkers from running a Apply Configuration or running any wizards while you are doing so.

1. rm -f /usr/local/nagios/etc/static/*
1. CCM > Tools > Config File Management > Delete Files
2. CCM > Tools > Config File Management > Write Configs
3. CCM > Tools > Config File Management > Verify Files
if all is good, immediately run Apply Configuration

The Apply Configuration when successful will reset the last known good configuration to not contain the files that were removed from static.
