Hello,

Unfortunately, old versions of CLAPI can sometimes skip important values needed by the newer version of CLAPI.

Do you have the line of the CLAPI import that is causing the issue?

# centreon -u <user> -p <password> -i /tmp/services.txt

Was the command that generated the output written in my initial post… (user and password have been removed here, of course)
 

Hello,

Is there any messages before this line? If not, you should try to redo the import, you will have a lot of line  with “object already exists” but you should be able to detect what line is causing the issue. 
The output will look like:

Line X: Object already exists
<PHP ERROR MESSAGE>

The error is most likely caused by the line X+1.

The only message I get is:

PHP Warning:  Undefined array key 475 in /usr/share/centreon/www/class/centreon-clapi/centreonAPI.class.php on line 981

No “Line X: Object already exists” message at all...
