How to capture AWS VPC Flow Logs and analyze them
Amazon Web Services (AWS) provides a wealth of data about the traffic that flows through your Virtual Private Cloud (VPC). By capturing this data, you can gain insights into network patterns, detect anomalies, and improve the security and efficiency of your cloud environment. AWS VPC Flow Logs are a feature that allows you to capture information about the IP traffic going to and from network interfaces in your VPC. In this blog, we will discuss how to capture all fields of AWS VPC Flow Logs, send them to Kinesis Firehose, and then analyze them using OpenObserve's Logs UI and Dashboards..

Parsing Syslog Messages
VRL provides a powerful way to parse syslog messages,using the built-in `parse_syslog` . Some syslog messages may not be parsed effectively using the built-in `parse_syslog` function. In such cases, `parse_regex` can be used to extract meaningful data from syslog messages.

Revolutionizing Observability - Unveiling OpenObserve, the High-Performance, Cloud-Native Platform
OpenObserve is an open source, cloud native open source observability platform that provides ~140x (YMMV. Could be higher or lower based on data entropy) lower storage costs compared to Elasticsearch. Use cases include real-life log data, significantly reduces operational costs, and improves ease of use. It can scale to petabytes of data, is highly performant, and allows you to sleep better at night 😴. If you are looking for an observability tool for logs, metrics, and traces, take a look at OpenObserve and how its approach towards observability could help you build better software and save money on observability costs.
