log_analyzer_watch
Read-only
Watch log files incrementally by polling for new entries from a specified file position. Begin with position 0 to mark the current end, then use returned positions to fetch only new lines, with optional level and pattern filters.
Instructions
Watch a log file for new entries since a given position.
This enables polling-based log watching. First call with from_position=0
returns the current end-of-file position. Subsequent calls with the
returned position get new entries added since then.
Args:
file_path: Path to the log file to watch
from_position: File position to read from. Use 0 for initial call
(returns current end position), or use the returned
current_position from a previous call.
max_lines: Maximum lines to read per call (1-1000, default: 100)
level_filter: Filter by log levels, comma-separated (e.g., "ERROR,WARN")
pattern_filter: Regex pattern to filter messages
response_format: Output format - 'markdown' or 'json'
Returns:
New log entries since the last position, with updated position for
the next call.Input Schema
