Fixed In Version: logging-fluentd-docker-v3.9.22-2
Doc Type: Bug Fix
Doc Text:
Cause: We currently compute the number of fluentd outputs in the startup script run.sh. When the forward plugin is configured, it was not correctly counted. Consequence: We miss a number of output when the forward plugin is configured. The number of output is used for calculating the file buffer size and the size gets larger than expected. Fix: The logic of the calculation was fixed to include the forward plugin case. Result: The correct output number then the correct file buffer size is now derived when the forward plugin is configured.

Description François Cami 2018-04-18 14:39:32 UTC
Description of problem:
We currently compute NUM_OUTPUTS using the number of secure_outputs, but core fluentd can use the forward plugin instead, so we can miss a number of outputs.

from fluentd/run.sh:
sec_forward_files=$( grep -l "@type *secure_forward" ${CFG_DIR}/*/* 2> /dev/null || : 
grep "@type *secure_forward" $afile | while read -r line; do

forward_files=$( grep -l "@type .*forward" ${CFG_DIR}/*/* 2> /dev/null || : )
grep "@type .*forward" $afile | while read -r line; do
