docker fluentd driver

[sincera]

Hi,

    I'm using docker fluentd driver. In normal it works well. But today, I find a problem. I can't get any logs.

1. When I check the docker log, it show:

` Client attempting to renew session 0x3581efcf8793aa9 at /10.80.10.12:39255\" for logger fluentd: fluent#appendBuffer: Buffer full, limit 1048576`

2. Another node has different log:

` Accepted socket connection from /10.80.10.6:51624\" for logger fluentd: fluent#send: can't send logs, client is reconnecting`

The first one may be because my fluentd server down l long time. But I don't know how the second one come from.

My question is:

a. How to aviod 1 and 2.

b. If 1 or 2 happens, what can I do.

c. where does fluentd-driver cache the log file.

d. Does fluentd driver have some config file? if does, where it is.
