Features

• Log Aggregation - Consolidates real-time log streams from multiple distributed pods and containers into a single output.
• Container Log Streaming - Provides real-time streaming and filtering of logs from multiple pods and containers within a Kubernetes cluster.
• Kubernetes Workload Label Filters - Restricts output based on labels, namespaces, or status conditions to isolate specific resources in large environments.
• Log-Based Debugging - Enables isolating errors across cluster resources using metadata filters and regular expressions.
• Resource Pattern Selection - Identifies and tracks pods by matching resource names against regular expression patterns for dynamic stream management.
• Dynamic Resource Watching - Uses the Kubernetes watch API to automatically detect and attach to new pods matching filter criteria.
• Dynamic Pod Pattern Tracking - Maintains an accurate resource list by selecting pods using regular expressions and automatically tracking new items.
• Asynchronous Log Streaming - Utilizes asynchronous log streaming to maintain persistent connections to multiple pods simultaneously.
• Log Event Filters - Isolates relevant information by including or excluding log lines that match specific regular expression patterns.
• Distributed Log Aggregation - Unifies log streams from multiple distributed Kubernetes resources into a color-coded view.
• Distributed Monitoring Tools - Provides tools for tracking log output across distributed sets of pods in real time.
• Log Event Filtering - Isolates relevant system events by filtering log streams based on specific nodes, container states, or pod conditions.
• Kubernetes Stream Tailing - Streams and filters logs from multiple pods and containers using regular expressions.
• Log Stream Management - Manages continuous log streams by automatically adding new resources and removing deleted ones from the active view.
• Deployment Log Filters - Narrows the search scope by restricting log output to specific resource types like deployments or jobs.
• Namespace-Based Log Filtering - Filters massive amounts of container output by namespaces, labels, and content patterns.
• Real-Time Application Log Monitoring - Streams data from multiple Kubernetes sources simultaneously with color coding for real-time debugging.
• Integrated Kubernetes Debugging Tools - Provides a single-interface CLI for streaming logs and monitoring Kubernetes workloads.
• Log Output Templates - Processes log lines through a customizable engine to apply colors and structure based on metadata.
• Stream Multiplexing - Aggregates multiple asynchronous log streams from different containers into a single synchronized output stream.
• Log Output Formatting - Transforms log data into raw text, JSON, or custom templates to control output formatting.
• Regex-Based Log Filtering - Uses regular expressions to include or exclude specific log content from Kubernetes streams.
• Log Syntax Highlighting - Accelerates visual scanning by marking specific strings and distinguishing data sources using configurable colors.
• Command Line Tools - Tails logs from multiple pods and containers simultaneously.
