Sounds like you didn't grab some command definitions from your old install. Also this is clearly not a NagiosXI problem but a Core problem, can we move it to the appropriate forum?

You can find all of the included config files from your old setup by doing a

Code: Select all

[root@localhost etc]# grep ^cfg_ nagios.cfg
cfg_dir=/usr/local/nagios/etc/static
cfg_file=/usr/local/nagios/etc/contacttemplates.cfg
cfg_file=/usr/local/nagios/etc/contactgroups.cfg
cfg_file=/usr/local/nagios/etc/contacts.cfg
cfg_file=/usr/local/nagios/etc/timeperiods.cfg
cfg_file=/usr/local/nagios/etc/commands.cfg
cfg_file=/usr/local/nagios/etc/hostgroups.cfg
cfg_file=/usr/local/nagios/etc/servicegroups.cfg
cfg_file=/usr/local/nagios/etc/hosttemplates.cfg
cfg_file=/usr/local/nagios/etc/servicetemplates.cfg
cfg_file=/usr/local/nagios/etc/servicedependencies.cfg
cfg_file=/usr/local/nagios/etc/serviceescalations.cfg
cfg_file=/usr/local/nagios/etc/hostdependencies.cfg
cfg_file=/usr/local/nagios/etc/hostescalations.cfg
cfg_file=/usr/local/nagios/etc/hostextinfo.cfg
cfg_file=/usr/local/nagios/etc/serviceextinfo.cfg
cfg_dir=/usr/local/nagios/etc/hosts
cfg_dir=/usr/local/nagios/etc/services

Sorry. Couldnt find the appropriate forum. thats y i posted here.

[jdalrymple]

That's no problem, we can move it to Core easy enough.

Was my advice useful in solving your problem? Did you find your missing command definitions?

[sinkak]

i have problems connecting to the server.
as soon i connect i will post the result here.

Thank You

[jolson]

Sounds good - let us know what you find out.

[sinkak]

both have same files

old server
monitoring:/etc/nagios3$ grep ^cfg_ nagios.cfg
cfg_file=/etc/nagios3/commands.cfg
cfg_dir=/etc/nagios-plugins/config
cfg_dir=/etc/nagios3/conf.d


new server
@ip-new:/etc/nagios3$ grep ^cfg_ nagios.cfg
cfg_file=/etc/nagios3/commands.cfg
cfg_dir=/etc/nagios-plugins/config
cfg_dir=/etc/nagios3/conf.d

Well, the validation output is pretty clear about the problem:

Code: Select all

Error: Service check command 'check_nrpe_args' specified in service 'Free memory' for host 'ips06.wsa.local' no t defined anywhere!

Can you find this command definition anywhere?

[sinkak]

i couldnt find that command.
i gave up this method, deleted this files.
i am installing from scratch again.
may be add each host individually to config files.

[jdalrymple]

Adding the command definition should be trivial, 4 lines. In addition if your old server still exists it should be easy to find. Unless you really really need to I wouldn't rebuild from scratch.
