Solved: Message Logging with Syslog not configurable - Can... - Page 2

Skip to the first comment for a solution.

Hi there,

I'm currently trying to configure a MessageLogging-Policy with Syslog. Without defining the logLevel and without the use of variables for host, port, protocol, ... it works fine.

There seems to be a bug with the logLevel though. Everytime I want to define it, regardless what logLevel-value I choose, I get deployment errors, stating logLevel is not a part of the policy's schema:

"Error Saving Revision X
Error occurred while validation of bean log-error.xml. Reason: - Schema validation failed. Cause : unexpected element (uri:"", local:"logLevel"). Expected elements are <{}FormatMessage>,<{}SSLInfo>,<{}Message>,<{}Port>,<{}Host>,<{}Protocol>. Line number : 13. Column number : 19. File name : log-error.xml."

Furthermore, I want to use different syslog-servers for different environments. So I created a KeyValueMap holding the syslog-configuration parameters (Host, port, etc.). Extracting the values and assigning them to variables works fine. When I want to use them in the MessageLogging-Policy, however, I get the following deployment error:

" Error Saving Revision X
Error occurred while validation of bean log-error.xml. Reason: - Schema validation failed. Cause : Not a number: {syslog.port}. Line number : 7. Column number : 35. File name : log-error.xml."

(Validation also fails for all other variables except host)

Here's my MessageLogging configuration:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<MessageLogging async="false" continueOnError="false" enabled="true" name="log-error">  
	<DisplayName>log-error</DisplayName>  
	<Syslog>  
		<logLevel>ERROR</logLevel>
		<Message>[XYZ tag="{organization.name}" tag="{apiproxy.name}" tag="{environment.name}"] APIGEE Error ...</Message>  
		<Host>{syslog.host}</Host>  
		<Port>{syslog.port}</Port>  
		<Protocol>{syslog.protocol}</Protocol>  
		<SSLInfo>  
			<Enabled>{syslog.use-ssl}</Enabled>  
		</SSLInfo>  
		<FormatMessage>{syslog.format-message}</FormatMessage>  
	</Syslog>
</MessageLogging>

Would be great if someone could help me with these issues.

Thank you and regards, Jan

Hi.

Regarding

"Error Saving Revision X
Error occurred while validation of bean log-error.xml. Reason: - Schema validation failed. Cause : unexpected element (uri:"", local:"logLevel"). Expected elements are <{}FormatMessage>,<{}SSLInfo>,<{}Message>,<{}Port>,<{}Host>,<{}Protocol>. Line number : 13. Column number : 19. File name : log-error.xml."

The logLevel element is a child of MessageLogging, not a child of Syslog. Therefore you must use something like this:

<MessageLogging name="log-error">  
  <logLevel>ERROR</logLevel>
  <Syslog>  
    <Message>...</Message> 
    ...
  </Syslog>
</MessageLogging>

It is not possible to have the logLevel be determined by a variable.

Regarding the setting of host and port via variables, we have that feature request in the backlog. ref: b/65739579 .
