The network protocol over which Delphix Engine communicates with the syslog server is standardized in RFC 5424. As a protocol, it supports using either UDP (RFC 5426) or TCP (RFC 6587) as the underlying transport and optional TLS mapping has been introduced to encrypt the messages over the wire for security purposes (RFC 5425). However, as of this release, we only support syslog over UDP with no encryption, which implies that syslog messages are always sent in the clear and may be lost during transmission and delivered out of order due to the limitations of UDP.
To configure for syslog support, you must specify the communication end point to which the syslog server listens, which includes the hostname or IP address of the syslog server and an optional port number. The latter defaults to 514 according to the syslog standard but it can be changed if necessary.
System and user events generated by Delphix are always forwarded immediately to the syslog server, which ensures timely delivery of important events that may require immediate action.
A couple of different output formats are supported for messages delivered over syslog, namely, TEXT and JSON. The TEXT format is the default. To change the message format, as of this release, you must do so via the CLI.
- Log into the Delphix Setup application using sysadmin credentials.
- Select Delphix Engine Preferences > Syslog Configuration.
- Select the severity level of the messages you want sent to the SysLog server.
- Click the pencil icon next to Syslog Servers.
- Enter the SysLog server hostname/IP address and port number.
- Click Enable Syslog.
- Click Save.
