I've been looking to save some shell scripts into a file for collection by an agent like Fluentbit and sending them off to Cloudwatch and Datadog.
I came across this example online that works effectively with the use of jq.
__timestamp(){
date "+%Y%m%dT%H%M%S"
}
__log(){
log_level="$1"
message="$2"
echo '{}' | jq \
--arg timestamp "$(__timestamp)"
--arg log_level "$log_level" \
--arg message "$message" \
'.timestamp=$timestamp|.log_level=$log_level|.message=$message' >> logs.log
}
__log "INFO" "Hello, World!"
The only issue is that the output is formatting as a full JSON with newlines and tabs. It's easy to read visually, but not ideal for cloud logging services.
{
"timestamp": "20220203T162320",
"log_level": "INFO",
"message": "Hello, World!"
}
How can I adjust it to format the output on a single line like this?
{"timestamp": "20220203T171908","log_level": "INFO","message": "Hello, World!"}
