Weaver created ZOOKEEPER-5031:
---------------------------------
Summary: logback.xml ignores Java system properties
Key: ZOOKEEPER-5031
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-5031
Project: ZooKeeper
Issue Type: Bug
Components: audit
Affects Versions: 3.9.5
Environment: Zookeeper version: 3.9.5
OS: Alma Linux 9.7
Environment variable:
ZOO_LOG_DIR=/var/log/zookeeper
Reporter: Weaver
Assignee: Mohammad Arshad
The standard configuration of logback.xml ignores Java system properties. The
comment in the file says "Define some default values that can be overridden by
system properties" and attempts to do so, but the syntax appears to be
inaccurate. Despite setting the environment variable *ZOO_LOG_DIR* the audit
logfile is still placed in the running directory. I'm not sure if this is the
proper website for logback, but this reference says that local scope wins:
[https://logback.qos.ch/manual/configuration.html#lookupOrder]
Directly underneath that is how to properly set a default value
([https://logback.qos.ch/manual/configuration.html#defaultValuesForVariables).]
I'm not sure a default value is needed since the startup scrips and properties
files set sensible default already.
