[Linaro-validation] Is there a way which we can compress LAVA log output?

Hi,

To get more information I set "logging_level": "DEBUG" in json file:

https://staging.validation.linaro.org/scheduler/job/127250/multinode_definit...

which results a 71.2MB file of Dispatcher Log messages:

https://staging.validation.linaro.org/scheduler/job/127250.0

Except these Dispatcher Log messages, the stdout log in DEBUG mode is also huge - 12.2MB:

https://staging.validation.linaro.org/dashboard/attachment/173583/download

By comparison a 13MB CTS stdout file can become a tiny 454kB after compressed by xz:

https://staging.validation.linaro.org/dashboard/attachment/173586/download

So if we can do the same thing to LAVA's own stdout as well as dispatcher log, I then can set DEBUG without any worries.

Idea?

Thanks.
