EAP 7 access-log rotates to a new file name with an incorrect date string when the rotation happens after restaring

Solution Unverified - Updated

Environment

  • Red Hat JBoss Enterprise Application Platform (EAP)
    • 7.x

Issue

  • EAP 7 access-log rotates to a new file name with an incorrect date string when the rotation happens after restaring.
  • For example, if the access-log rotation happened after restarting JBoss instance at 2018/04/22, access_log for 2018/04/21 would be rotated to access_log.2018-04-22.log and access_log for 2018/04/22 would be rotated to access_log.2018-04-22-1.log:
$ ls -l standalone/log/access_log*
-rw-rw-r--. 1 <user> <group> 69 Apr 20  2018 standalone/log/access_log.2018-04-20.log
-rw-rw-r--. 1 <user> <group> 69 Apr 22  2018 standalone/log/access_log.2018-04-22-1.log // this should be access_log.2018-04-22.log
-rw-rw-r--. 1 <user> <group> 69 Apr 21  2018 standalone/log/access_log.2018-04-22.log // this should be access_log.2018-04-21.log
-rw-rw-r--. 1 <user> <group> 69 Apr 23  2018 standalone/log/access_log.log

Resolution

The following JIRAs are raised to improve the behavior in the future release of JBoss EAP:

Until it's fixed, you can workaround this issue by enabling use-server-log option in <access-log> and using the rotation feature provided by logging subsystem. (Please also refer to this knowledge article). For example:

# Configure `<access-log>` with setting `use-server-log` attribute to true:
/subsystem=undertow/server=default-server/host=default-host/setting=access-log:add(pattern="%h %l %u %t \"%r\" %s %b \"%{i,Referer}\" \"%{i,User-Agent}\" \"%{i,COOKIE}\" \"%{o,SET-COOKIE}\" %S \"%I\" %T")
/subsystem=undertow/server=default-server/host=default-host/setting=access-log:write-attribute(name=use-server-log, value=true)
/subsystem=undertow/server=default-server/http-listener=default:write-attribute(name=record-request-start-time,value=true)

# Configure a custom handler for access logging in logging subsystem: 
/subsystem=logging/pattern-formatter=access-log-formatter:add(pattern="%s%n")
/subsystem=logging/periodic-rotating-file-handler=access-log:add(autoflush=true, append=true, named-formatter=access-log-formatter, suffix=".yyyy-MM-dd", file={path=access_log.log, relative-to=jboss.server.log.dir})
/subsystem=logging/logger=io.undertow.accesslog:add(handlers=[access-log], use-parent-handlers=false)
