Fluent-bit 3.0.4 throwing repeated warnings ( [ warn] [record accessor] translation failed, root key=hec_token) #8859

I think there's a problem with this PR. We're getting spammed with the same message as the user above, millions of times per minute: |
|
We have same error |
|
Same error It started appearing right after we started using the latest helm chart 0.46.7 with app version 3.0.4 |
|
we are looking into this. |
The following patch perform 2 changes in the code that helps to fix the problems found with Splunk hec token handling: 1. In the recent PR #8793, when using the record accessor API flb_ra_translate_check() to validate if the hec_token field exists, leads to noisy log messages since that function warns the issue if the field is not found. Most of users are not using hec_token set by Splunk input plugin, so their logging gets noisy. This patch replaces that call with flb_ra_translate() which fixes the problem. 2. If hec_token was set in the record metadata, it was being store in the main context of the plugin, however the flush callbacks that formats and deliver the data runs in separate/parallel threads that could lead to a race condition if more than onen thread tries to manipulate the value. This patch adds protection to the context value so it becomes thread safe. Signed-off-by: Eduardo Silva <eduardo@calyptia.com>
