Problem to add or remove new host / services

[Grejao]

i import all my hosts and services from nagios (2.10) ... all imports are ok.
But after migrate from nagios to centreon i can not add more hosts or services, i add hosts and services at configuration panel, but they don't appear at monitoring panel.

How do i configure new hosts and services to appear at monitoring after create then in configuration panel?

[juraj]

You do restart nagios with the "move export files" on, do you?

[Grejao]

No, i don't.

Every time that i add new hosts and services in centreon configuration panel i need to run
Centreon > Configuration > Nagios > Generate
to restart nagios and mark move export files?

i need to run it to get effects every time that i change some configuration?

[juraj]

That is correct, as far as I understand.

[Grejao]

i create a new host, create new services for this host, remove old services from an existent host. But when i try to restart Nagios by centreon i receive the following message at state:

i open my /usr/local/centreon/filesGeneration/nagiosCFG/services.cfg and copy a piece of code for you see that have no errors at point where centreon says that have errors.

but i don't understand when they say:

I can access nagios normally by the same web host from centreon.
centreon: http://servers/centreon/
nagios: http://servers/nagios


and after this tryed to restart Nagios by centreon no new servers and hosts appear at monitoring panel.

[juraj]

Well, the first part of the error message sounds self-descriptive (invalid max_attempts etc). Are all of those filled in?
I would bet that the second error message about the bad file name will magically disappear once you solve the first one.

[Grejao]

i fix the problem reconfiguring all services and setting max_attempts, check_interval, retry_interval and notification_interval for all services.

after this i receive another problem, that my users doesn't has no service notification commands defined! o no host notification commands defined.

I try to edit users and set informations, but when i try to save i receive the following message on Alias field:
" that You have to keep at least one contact to access to Centreon "

i put many informations at this field but i can't fix it.
someone can help-me?

[Grejao]

ok, Now i fix all problems, restart nagios by shell and by centreon panel. all hosts appear at monitoring panel.


Now i need to create graphs and doesn't know how do i do this :s ... at Centreon views i have no hosts to select.

[Guigui2607]

You can find a tutorial in the Wiki at this url:
http://wiki.oreon-project.org/index.php/Graphs

I hope it will help you.

[Grejao]

but this document says that i need to have perfdata instaled and configured to generate graphs.
I don't remember where, but i remember that i read some post saying that Oreon Data Storage(ODS - now CDS) replaces perfdata and that i didn't need perfdada to generate graphs.

whats the correct?

[juraj]

It's perfparse that you don't need anymore.
If I understand correctly nagios picks up performance data, stores them in perfdata file, ods picks them up from there and stores them in *.rrd files.
So for graphs you do need perfdata, but not perfparse.

The link you will find two posts back will guide you.

[Grejao]

Ok. thanks for help-me :) .


I'm using Centreon 1.4.2.1.

Now i configure part of article.

I do the "Perfdata activation in Nagios", and it create a new file /usr/local/nagios/var/service-perfdata with no problem and store data from my check commands, look:

I didn't understand this option.

[Guigui2607]

So, Nagios create the service-perfdata file. (in /usr/local/nagios/var/service-perfdata)

-> Keep "Path to RRDtool Database" to /var/lib/ods/database for the moment...

But ODS not parse the service-perdata file. (in /usr/local/nagios/var/service-perfdata)
Is ODS service started ?
If not, start it, wait a few minutes and check if rrd files are present in your "RRDtool Database" direcrtory...

[-Archi-]

You don't have to set any "Performance Data File Processing Command", ODS is the processing command that will process all of your data. But the other problem is that your service-perfdata file does not contain any perfdata, just basic Nagios plugin results. You have to configure your plugin/command to send perfdata after the basic output in the "output | perfdata" format or you won't have any graphs, since they are built from that.

Don't forget to also upgrade to Centreon 1.4.2.3 which is a bugfix of 1.4.2.x branch.

Ok, i set path to rrdtool database to /var/lib/ods/database.
yeap, ODS is started ok

Ok, i upgrade my centreon to 1.4.2.3 without problems. But i didn't understand your parse from my problem. Where i need to change to ods get data from perfdata?

my perfdata are writing ok on /usr/local/nagios/var/service-perfdata.

what i need to change at "Configuration > Nagios > Nagios CFG" ???

I have this fields:

Juste read my first sentence, you must have empty "Host Performance Data File Processing Command" and "Service Performance Data File Processing Command", you don't need to specify Host/Service Performance Data File either so :

Performance Data Processing Option Yes
Host Performance Data Processing Command process-host-perfdata
Service Performance Data Processing Command process-service-perfdata
Host Performance Data File <nothing>
Service Performance Data File <nothing>
Host Performance Data File Template <nothing>
Service Performance Data File Template <nothing>
Host Performance Data File Mode a w Default <nothing>
Service Performance Data File Mode a w Default <nothing>
Host Performance Data File Processing Interval <nothing>
Service Performance Data File Processing Interval <nothing>
Host Performance Data File Processing Command <nothing>
Service Performance Data File Processing Command <nothing>

Then, your biggest problem is in the definition of your "process-service-perdata" command, your service-perfdata file is filled with [SERVICEPERFDATA] instead of actual perfdata. Edit this command, it should contain exactly the following line (without any line feed or extra characters) :

$USER1$/process-service-perfdata "$LASTSERVICECHECK$" "$HOSTNAME$" "$SERVICEDESC$" "$SERVICEOUTPUT$" "$SERVICESTATE$" "$SERVICEPERFDATA$"
