Calyptia Fluent Bit
One of the features of Calyptia Fluent Bit + LogDNA integration is the ability to auto enrich each record with further context.
When the plugin process each record (or log), it tries to lookup for specific key names that might contain specific context for the record in question, the following table describe the keys and the discovery logic:
level
If the record contains a key called level or severity, it will populate the context level key with that value. If not found, the context key is not set.
file
if the record contains a key called file, it will populate the context file with the value found, otherwise If the plugin configuration provided a file property, that value will be used instead (see table above).
app
If the record contains a key called app, it will populate the context app with the value found, otherwise it will use the value set for app in the configuration property (see table above).
meta
if the record contains a key called meta, it will populate the context meta with the value found.
The following configuration example, will emit a dummy example record and ingest it on LogDNA. Copy and paste the following content in a file called logdna.conf:
run Calyptia Fluent Bit with the new configuration file:
