PSR Log
An interface that describes a logger
The main goal is to allow libraries to receive a Psr\Log\LoggerInterface object and write logs to it in a simple and universal way. The LoggerInterface exposes eight methods to write logs to the eight RFC 5424 levels (debug, info, notice, warning, error, critical, alert, emergency). Every method accepts a string as the message, or an object with a toString() method. Implementors MAY have special handling for the passed objects. If that is not the case, implementors MUST cast it to a string. The interfaces and classes described as well as relevant exception classes and a test suite to verify your implementation are provided as part of the psr/log package. ... -

Logrus
Structured, pluggable logging for Go
Logrus is a structured, pluggable logger for Go (golang) that is completely API compatible with the standard library logger. It encourages careful, structured logging through much more discoverable logging fields rather than long, unparseable error messages. This produces much more useful logging messages. Logrus is currently in maintenance mode, which means that new features will no longer be introduced. This does not mean however, that it is dead. It continues to be maintained for security, backwards compatibility and performance, so you can still rely on it for structured logging in Golang. ... -

winston
A logger for just about everything
...A transport is essentially a storage device for your logs. Each winston logger can have multiple transports (see: Transports) configured at different levels (see: Logging levels). For example, one may want error logs to be stored in a persistent remote location (like a database), but all logs output to the console or a local file. Winston aims to decouple parts of the logging process to make it more flexible and extensible. Attention is given to supporting flexibility in log formatting (see: Formats) & levels (see: Using custom logging levels), and ensuring those APIs decoupled from the implementation of transport logging (i.e. how the logs are stored / indexed, see: Adding Custom Transports) to the API that they exposed to the programmer. -

defmt
Efficient, deferred formatting for logging on embedded systems
defmt ("de format", short for "deferred formatting") is a highly efficient logging framework that targets resource-constrained devices, like microcontrollers. In its current iteration defmt mainly targets tiny embedded devices that have no means to display information to the developer, e.g. a screen. In this scenario, logs need to be transferred to a second machine, usually a PC/laptop, before they can be displayed to the developer/end-user. -

Flogger
A Fluent Logging API for Java
...Instead of building messages eagerly, it uses lazy parameter evaluation so expensive string building only happens when a log statement is actually emitted. The API encourages structured key–value context and fine-grained rate limiting, which helps keep logs informative without flooding systems during high-traffic or error storms. Handlers (backends) can route the same log record to multiple destinations—console, files, cloud logging—while preserving structured fields for search and alerting. Its fluent style reduces boilerplate and guides developers toward consistent log levels, formatting, and metadata. Because it’s designed for large codebases, Flogger emphasizes performance, binary size discipline, and compatibility with existing logging infrastructures. -

We! Analyze By Or Cohen
We! Analyze - designed to analyze ArcSight SmartConnectors logs.
...Also, many single connectors collect events from multiple locations (multi database, multi file, WUC) and we might never know one of these locations is unavailable as events from the other locations are arriving so the connector seems to be working fine. Eventually, when we do understand that something is wrong, it takes a while to analyze, understand and solve. In light of these problems in the process of error detection in connectors, I have developed is an automated tool named 'We! Analyze' with its own UI which analyzes connector logs manually or using an API that can be started from the command line, a schedule task or from the console with an action in rule, tool or integration command (if you use the API you can forward the events to a syslog listener in CEF format). -
