If you have JSON-formatted logs that you want to ingest and process with Logstash, follow these steps:
Assuming you have logs in the following JSON format:
{"status": 200, "ip": "127.0.0.1", "level": 30, "msg": "Connected to database", "pid": 17089, "timestamp": 1696150204}
{"status": 200, "ip": "127.0.0.1", "level": 30, "msg": "Task completed successfully", "pid": 17089, "timestamp": 1696150207}
You can read these JSON logs with the following Logstash configuration:
input {
file {
type => "json"
path => "/var/log/mylogs.log"
}
}
filter {
json {
source => "message"
}
}
output {
file {
path => "/var/log/out.log"
}
}
This Logstash configuration reads JSON data from /var/log/mylogs.log, parses it using the JSON filter, and outputs the processed data to /var/log/out.log. Each incoming event (or log line) has the JSON message field parsed, and the resulting structured data is written to the output file.
