You probably have some error in the nagios oracle settings that don't match tnsnames.ora. The internet can tell you exactly what ORA-12154 means.
Think about searching the internet about your question. It will give you a million possibilities in the blink of an eye.

First I checked there the problem is that my half DB has this problem and they are version 19 ( SQL> SELECT version FROM v$instance;

VERSION
-----------------
19.0.0.0.0
)

With version 18 I have no problems ( SQL> SELECT version FROM v$instance;

VERSION
-----------------
18.0.0.0.0
)

So the so the TNSNAMES.ORA files are the same also .cfg nagios files are the same but in version 19 not working.
