Team,

 

I am new to syslog-ng and recently installed syslog-ng v3.23 on RHEL 8.  However while trying to restart syslog-ng service it is failing with below error.

 

I read it on some blog that installing “http” should fix it but didn’t find any steps on how to intall the module.  I did try to do a fresh installation of syslog-ng 3.23 and no luck there.

 

Plugin module not found in 'module-path'; module-path='/usr/lib64/syslog-ng', module='http'

 

Thank you

NG.
