+
+Logs from the post-deploy hook are located on the server in the following locations:

+> Note1:
+> `var/log/cloud.log` logs on the Staging and Production environments are only available on the first node in the cluster.

+> Note2:
+> Logs in the /var/log/ directory are not shared between nodes of the enterprise server cluster; 
+> each server has its own log. We recommend checking logs on every node for complete reporting.
