Problems regarding nagios.cfg with defined services and hosts (generated by Nagiosql) - nagios

Question

Nagiosql generated files make problems during preflight check - but everythings seems to be okay.
/etc/nagios/nagios.cfg
....
## Hosts
cfg_dir=/etc/nagiosql/hosts/
cfg_file=/etc/nagiosql/hosttemplates.cfg
cfg_file=/etc/nagiosql/hostgroups.cfg
cfg_file=/etc/nagiosql/hostextinfo.cfg
cfg_file=/etc/nagiosql/hostescalations.cfg
cfg_file=/etc/nagiosql/hostdependencies.cfg
## Services
cfg_dir=/etc/nagiosql/services/
cfg_file=/etc/nagiosql/servicetemplates.cfg
cfg_file=/etc/nagiosql/servicegroups.cfg
cfg_file=/etc/nagiosql/serviceextinfo.cfg
cfg_file=/etc/nagiosql/serviceescalations.cfg
cfg_file=/etc/nagiosql/servicedependencies.cfg
...
nagios -v /etc/nagios/nagios.cfg
....
Running pre-flight check on configuration data...
Checking services...
Error: There are no services defined!
Checked 0 services.
Checking hosts...
Error: There are no hosts defined!
Checked 0 hosts.
The content seems okay to me
[root#xxx services]# cd /etc/nagiosql/services/
[root#xxx services]# ls -alh
total 20K

-rw-r--r-- 1 apache nagios 948 Aug 11 07:12 psm01.cfg
Content also seems to be fine (generated by nagiosql):

Can somebody tell me where the solution for this problem is? Already wasted 2 hours...

Answer 1

Try removing the final slash from the directory names in your cfg_dir definitions and see if that doesn´t get it to recognize the cfg files in that directory.
For example,
Change:
cfg_dir=/etc/nagiosql/hosts/
...
cfg_dir=/etc/nagiosql/services/
To:
cfg_dir=/etc/nagiosql/hosts
...
cfg_dir=/etc/nagiosql/services
EDIT:
Okay I think directory permissions may be causing the cfg_dir evaulations to fail. According to the ls -alh output you listed, your /etc/nagiosql/hosts/, /etc/nagiosql/services/, and /etc/nagiosql/ directories do not grant write permissions to the nagios group. Nagios will need to get a directory listing for those directories and will need group write permissions to do it.
To remedy:
chmod g+w /etc/nagiosql/hosts/
chmod g+w /etc/nagiosql/services/
Restart nagios service.
Also, you don't need to remove the slashes from the directory paths in the nagios cfg_dir configurations. Nagios will strip the trailing slash (/) for you, according to the code:
https://github.com/NagiosEnterprises/nagioscore/blob/eb8e83d5d05e572eb8c0d4d4764885c5427b4b69/xdata/xodtemplate.c#L327
/* process all files in a config directory */ else if(!strcmp(var, "xodtemplate_config_dir") || !strcmp(var, "cfg_dir")) {
if(config_base_dir != NULL && val[0] != '/') {
asprintf(&cfgfile, "%s/%s", config_base_dir, val);
} else
cfgfile = strdup(val);
/* strip trailing / if necessary */ if(cfgfile != NULL && cfgfile[strlen(cfgfile) - 1] == '/')
cfgfile[strlen(cfgfile) - 1] = '\x0';
/* process the config directory... */ result = xodtemplate_process_config_dir(cfgfile, options);
my_free(cfgfile);
/* if there was an error processing the config file, break out of loop */ if(result == ERROR)
break; } }
EDIT #2: In the host definition you posted, your register value is set to 0. Try setting it to 1 instead. register 0 is used for templates that will be inherited from, but will not actually show up in the Nagios UI.
Change:
define host {
host_name GIT
alias GIT Server
address 172.25.10.80
register 0
}
To:
define host {
host_name GIT
alias GIT Server
address 172.25.10.80
register 1
}
Also please set register 1 for your service definitions as well.

Answer 2

Try adding executable permissions to your directories. Some programs and languages require +x permissions in order to actually open the directory.
If that doesn't work, temporarily set everything to 0777 permissions to see if the issue is permissions related at all.
You also have config problems even if you get that part working. Your host and service configs don't have a use directive in them, which points to a template that would have most of the default values. The register directive is implied as 1 unless you specifically set it to 0 for a template. See the object definitions docs if you need a reference: https://assets.nagios.com/downloads/nagioscore/docs/nagioscore/3/en/objectdefinitions.html
