Building a scalable monitoring function for large-scale deployments can be challenging as there could be billions of data points captured each day. Additionally, the volume of logs and the number of metrics can be difficult to manage without a suitable big data platform with streaming and visualization support.
Voluminous logs collected from applications, servers, network devices, and so on are processed to provide real-time monitoring that help detect errors, warnings, failures, and other issues. Typically, various daemons, services, and tools are used to collect/send log records to the monitoring system. For example, log entries in the JSON format can be sent to Kafka queues or Amazon Kinesis. These JSON records can then be stored on S3 as files and/or streamed to be analyzed in real time (in a Lambda architecture implementation)....
