log4j v1

[uptimestar]

Hi, where is v1 on github?

(v2 does not work in jars, known issue)

[asafm]

Can you clarify on known issue? We stopped supporting v1 as it has bugs we can’t fix due to the way v1 was designed, solved in v2. Also v1 is no longer supported by log4j as well.

Sure: in the logs on logz.io there is no hostname displayed. I can't tell what log message came from what machine.
How can I set it up so host is displayed. Here is my log4j.properties. Logz.io ticket# 2871
I can also send you screen shot of my logz.io that shows there is no hostname displayed with the logs. One there is an exception, how can I tell what server it was on?

#log4j.rootLogger=INFO, stdout
log4j.rootLogger=INFO, LogzioAppender, stdout

for prod - get token from longzo.io

log4j.appender.LogzioAppender = io.logz.log4j.LogzioAppender
log4j.appender.LogzioAppender.logzioToken = XXX
log4j.appender.LogzioAppender.logzioUrl = http://listener.logz.io:8070
#log4j.appender.LogzioAppender.logzioType = myAppName
log4j.appender.LogzioAppender.layout.type = PatternLayout
log4j.appender.LogzioAppender.layout.pattern = [%p%L] %c{1} - %m%n

IDE only

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern= [%p%L] %c{1} - %m%n

Hi @uptimestar,

You can add the hostname field to your logs in one of the following ways:

1. Use the addHostname param: log4j.appender.LogzioAppender.addHostname = true
2. Use the additionalFields param and add hostname yourself: log4j.appender.LogzioAppender.additionalFields = "hostname=$HOSTNAME_ENV_VAR"

I suggest you go with the second way because you can control the value that will be sent.

Works! (FYI log4jv2 does not work even by self when deployed in jar - known issue w/ them).
Thx.

@uptimestar Please let us know if this solved your issue.

@cekvenich What do you mean by log4jv2 does not work ?
What version of log4j did you try to use it with ?

[cekvenich]

Yes, I solved it, it works w/ log4j1 appender. I can see hostname in dashboard.

Log4jv2 does not work by itself - nothing to do w/ logz.io. Known bug a year old. When you deploy w/ jar. You can just make a console logger and it does not work in production. Works in IDE and development - but does not work when deployed. Don't worry about it.
