We deploymed our fluentd application on AKS. From the past few days we are seeing multiple warnings in our aks pods.

[warn]: #6 buffer flush took longer time than slow_flush_log_threshold: elapsed_time=34.518092500045896 slow_flush_log_threshold=20.0

Recently we are receiving more logs compared to the previous days. I guess this might be the reason for these warnings. However I see some decrease in the output feeds in Event hubs which is a concern.

<match udp.**>
@type azureeventhubs_e
connection_string "#{ENV['EH_CONNECTIONSTRING']}"
hub_name "#{ENV['EH_ENTITY']}"
batch true
print_records false
<buffer>
retry_forever false
total_limit_size 2GB
chunk_full_threshold 0.1
flush_interval 1s
flush_thread_count 36
retry_max_times 2
overflow_action block
</buffer>
</match>

Can anyone help, How I can avoid these warnings?

    Have you tried increasing `flush_interval to 5,10 or even 30` ? Also check https://docs.fluentd.org/deployment/multi-process-workers – Riz Jul 01 '22 at 15:26
