No data available, process_perfdata.pl shown error, issues after RAM disk installation

Hi team, anyone know why after RAM disk installation ends with out performance graps? I follow the procedure for scrip installation successfully. I realize that the process_perfdata.pl script shown this error:


[linuxadmin@AZUNGSP01 ~]$ perl /usr/local/nagios/libexec/process_perfdata.pl
Can't locate warnings.pm: /usr/local/lib64/perl5/warnings.pm: Permission denied at /usr/local/nagios/libexec/process_perfdata.pl line 27.
BEGIN failed--compilation aborted at /usr/local/nagios/libexec/process_perfdata.pl line 27.


Which perl out:
[linuxadmin@AZUNGSP01 ~]$ which perl
/usr/bin/perl


Whereis out:
[linuxadmin@AZUNGSP01 ~]$ whereis perl
perl: /usr/bin/perl /usr/share/man/man1/perl.1.gz



In te config files all the path were updated by the script and point to:
/var/nagiosramdisk/spool/perfdata/
/var/nagiosramdisk/spool/xidpe/

The RAM disk created:
tmpfs 500M 884K 500M 1% /var/nagiosramdisk


When i ty the next:
[root@AZUNGSP01 linuxadmin]# tail -f /usr/local/nagios/var/perfdata.log
tail: cannot open '/usr/local/nagios/var/perfdata.log' for reading: No such file or directory
tail: no files remaining

I realized thath the perfdata.log is missing in the system.

I hope those details help to provide somo visibility for the issue.

My system is:
Nagios XI 5.9.2
RHEL 8 64
