# fluentd fails to send a chunk to the server => writes it to the log =>

# Writing to a file, which is not exported to the back-end prevents it.

# Liveness probe is aimed to help in situarions where fluentd

|
# silently hangs for no apparent reasons until manual restart.

|
# The idea of this probe is that if fluentd is not queueing or
|
|
# flushing chunks for 5 minutes, something is not right. If
|
|
# you want to change the fluentd configuration, reducing amount of
|
|
# logs fluentd collects, consider changing the threshold or turning
|
|
# liveness probe off completely.
