I'm trying to debug why I get NoNodeAvailableExceptions after my client has been running for a few minutes. I found a post on here that suggested turning up the logging level for org.elasticsearch.discovery but I can't seem to do this (I know, dumb problem to have). I'm not using any logging API in my code (its just prototype for the moment), but the log4j jar is there and there's a log4j.xml [https://gist.github.com/2710431](https://gist.github.com/2710431) file. Where am I supposed to set the logging settings?! ---

\*\*TYPO: the package I want to set to DEBUG level logging is org.elasticsearch.client.transport On Wednesday, May 16, 2012 9:45:49 AM UTC-4, shadow000fire wrote: > I'm trying to debug why I get NoNodeAvailableExceptions after my client > has been running for a few minutes.

Are you trying to log on the client or server side? On the server side, there is a logging.yml file in the config directory. For the client side, it is all up to your logging setup. Is log4j working at all? -- Ivan On Wed, May 16, 2012 at 6:49 AM, shadow000fire [jason.scheller@gmail.com](mailto:jason.scheller@gmail.com) wrote: > \*\*TYPO: the package I want to set to DEBUG level logging is > org.elasticsearch.client.transport > > On Wednesday, May 16, 2012 9:45:49 AM UTC-4, shadow000fire wrote: > > > I'm trying to debug why I get NoNodeAvailableExceptions after my client > > has been running for a few minutes.

Thanks Ivan. No, log4j wasn't working at all on the client side (server side works fine) and I'm not familiar with log4j. Turns it log4j doesn't understand -Dlog4j.configuration=C:\workspaces\ES\ESBenchmark\log4j.xml because its expecting a URL, so I had to make it -Dlog4j.configuration=file:///C:\workspaces\ES\ESBenchmark\log4j.xml. I knew it was something dumb. On Wednesday, May 16, 2012 11:10:40 AM UTC-4, Ivan Brusic wrote: > Are you trying to log on the client or server side?

Logging has never been easy on the JVM. Too many different formats, third-party libs bundling their own, embedded jars, etc.. Glad you got it working. -- Ivan On Wed, May 16, 2012 at 8:13 AM, shadow000fire [jason.scheller@gmail.com](mailto:jason.scheller@gmail.com) wrote: > Thanks Ivan.
