Hera Log Query Guide

Overview

This guide covers Hera log detail query operations using Python scripts. The skill provides functionality to query Hera log details with various filters including spaceId, storeId, input search terms, tailName, and time ranges.

Quick Start

import sys
sys.path.append('scripts')
from hera_log_detail_query import query_log_detail

# Query logs with basic parameters
result = query_log_detail(
    space_id=123,
    store_id=456,
    tail_name="test-tail-name"
)

# Query logs with all parameters
result = query_log_detail(
    space_id=123,
    store_id=456,
    tail_name="test-tail-name",
    input_text="error message",
    start_time="1638316800000",
    end_time="1638320400000"
)

Main Function

query_log_detail - Query Hera Log Details

Query Hera log details with filters.

Parameters:

space_id (int, required): Space ID
store_id (int, required): Store ID
tail_name (str, required): Tail name, e.g., "test-tail-name"
input_text (str, optional): Search input content, may contain special characters like quotes
start_time (str, optional): Query start time in milliseconds timestamp string. Defaults to 1 hour ago
end_time (str, optional): Query end time in milliseconds timestamp string. Defaults to current time
api_url (str, optional): API endpoint URL. Uses default from environment if not specified

Returns:

JSON response from Hera API containing log details

Example:

from hera_log_detail_query import query_log_detail

# Basic query
result = query_log_detail(
    space_id=123,
    store_id=456,
    tail_name="my-app-logs"
)

# Query with search term
result = query_log_detail(
    space_id=123,
    store_id=456,
    tail_name="my-app-logs",
    input_text="ERROR"
)

# Query with custom time range
import time
end_time = int(time.time() * 1000)
start_time = end_time - 3600000  # 1 hour ago

result = query_log_detail(
    space_id=123,
    store_id=456,
    tail_name="my-app-logs",
    start_time=str(start_time),
    end_time=str(end_time)
)

Common Tasks

Query Recent Logs

from hera_log_detail_query import query_log_detail

# Query logs from the last hour (default)
result = query_log_detail(
    space_id=123,
    store_id=456,
    tail_name="application-logs"
)

print(result)

Search for Specific Log Messages

from hera_log_detail_query import query_log_detail

# Search for error logs
result = query_log_detail(
    space_id=123,
    store_id=456,
    tail_name="application-logs",
    input_text="Exception"
)

print(result)

Query Logs in Custom Time Range

from hera_log_detail_query import query_log_detail
import time

# Query logs from 2 hours ago to 1 hour ago
current_time = int(time.time() * 1000)
end_time = str(current_time - 3600000)  # 1 hour ago
start_time = str(current_time - 7200000)  # 2 hours ago

result = query_log_detail(
    space_id=123,
    store_id=456,
    tail_name="application-logs",
    start_time=start_time,
    end_time=end_time
)

print(result)

Configuration

The default API URL is configured in the script. You can override it by:

Setting environment variable HERA_LOG_DETAIL_API_URL
Passing api_url parameter to the function

Error Handling

The script includes comprehensive error handling:

Parameter validation for required fields
HTTP request error handling
JSON parsing error handling
Detailed error messages for troubleshooting
