splunk-assistant-skills-lib 0.2.0

Shared library for Splunk Assistant Skills - HTTP client, configuration management, error handling, and utilities for Splunk REST API automation

Splunk Assistant Skills Library

A shared Python library for interacting with the Splunk REST API. Provides HTTP client, configuration management, error handling, validators, and utilities for building Splunk automation tools.

Installation

pip install splunk-assistant-skills-lib

Quick Start

from splunk_assistant_skills_lib import get_splunk_client, handle_errors, validate_spl

@handle_errors
def main():
    # Get a configured client (reads from environment or config file)
    client = get_splunk_client()

    # Validate and execute a search
    spl = validate_spl("index=main | head 10")
    results = client.post(
        '/search/jobs/oneshot',
        data={'search': spl, 'output_mode': 'json'}
    )
    print(results)

if __name__ == '__main__':
    main()

Features

HTTP Client (SplunkClient)

• Dual authentication: JWT Bearer token (preferred) or Basic Auth
• Automatic retry with exponential backoff on 429/5xx errors
• Configurable timeouts for short and long-running operations
• SSL verification with option to disable for self-signed certs
• Streaming support for large result sets

from splunk_assistant_skills_lib import SplunkClient

client = SplunkClient(
    base_url="https://splunk.example.com",
    token="your-jwt-token",
    port=8089,
    verify_ssl=True
)

# GET request
info = client.get("/server/info")

# POST request
job = client.post("/search/jobs", data={"search": "index=main | head 10"})

# Stream results
for chunk in client.stream_results(f"/search/jobs/{sid}/results"):
    process(chunk)

Configuration Management

Multi-source configuration with profile support:

1. Environment variables (highest priority)
2. .claude/settings.local.json (personal, gitignored)
3. .claude/settings.json (team defaults)
4. Built-in defaults (lowest priority)

from splunk_assistant_skills_lib import get_splunk_client, get_config

# Use default profile
client = get_splunk_client()

# Use specific profile
client = get_splunk_client(profile="production")

# Get configuration
config = get_config(profile="production")

Environment Variables:

• SPLUNK_TOKEN - JWT Bearer token
• SPLUNK_USERNAME / SPLUNK_PASSWORD - Basic Auth credentials
• SPLUNK_SITE_URL - Splunk host URL
• SPLUNK_MANAGEMENT_PORT - Management port (default: 8089)
• SPLUNK_PROFILE - Profile name to use
• SPLUNK_VERIFY_SSL - SSL verification (true/false)

Error Handling

Comprehensive exception hierarchy and @handle_errors decorator for CLI scripts:

from splunk_assistant_skills_lib import (
    handle_errors,
    SplunkError,
    AuthenticationError,
    ValidationError,
    NotFoundError,
)

@handle_errors
def main():
    # Exceptions are caught and printed nicely
    client = get_splunk_client()
    client.get("/nonexistent")  # Raises NotFoundError

Exception Hierarchy:

• SplunkError (base)
  • AuthenticationError (401)
  • AuthorizationError (403)
  • ValidationError (400)
  • NotFoundError (404)
  • RateLimitError (429)
  • SearchQuotaError (503)
  • JobFailedError
  • ServerError (5xx)

Input Validators

Validate Splunk-specific formats:

from splunk_assistant_skills_lib import (
    validate_spl,
    validate_sid,
    validate_time_modifier,
    validate_index_name,
)

# Validates SPL syntax (balanced parens, valid pipes, etc.)
spl = validate_spl("index=main | stats count by host")

# Validates search job ID format
sid = validate_sid("1703779200.12345")

# Validates time modifier format
time = validate_time_modifier("-1h@h")

# Validates index name
index = validate_index_name("main")

SPL Query Building

Build and optimize SPL queries:

from splunk_assistant_skills_lib import (
    build_search,
    add_time_bounds,
    estimate_search_complexity,
    parse_spl_commands,
)

# Build search with common options
spl = build_search(
    "error",
    index="main",
    earliest_time="-1h",
    latest_time="now",
    fields=["host", "message"],
    head=100
)

# Estimate complexity
complexity = estimate_search_complexity(spl)  # 'simple', 'medium', 'complex'

# Parse into commands
commands = parse_spl_commands(spl)  # [('search', '...'), ('fields', '...')]

Job Polling

Monitor and manage search jobs:

from splunk_assistant_skills_lib import (
    poll_job_status,
    cancel_job,
    pause_job,
    JobState,
)

# Poll until completion
progress = poll_job_status(client, sid, timeout=300)
print(f"Results: {progress.result_count}")

# Cancel a job
cancel_job(client, sid)

# Check job state
if progress.state == JobState.DONE:
    print("Job completed successfully")

Time Utilities

Work with Splunk time modifiers:

from splunk_assistant_skills_lib import (
    parse_splunk_time,
    format_splunk_time,
    validate_time_range,
    get_time_range_presets,
)

# Parse time modifier to datetime
dt = parse_splunk_time("-1h")

# Format datetime as Splunk time
time_str = format_splunk_time(dt, format_type="epoch")

# Validate time range
is_valid, error = validate_time_range("-1h", "now")

# Get common presets
presets = get_time_range_presets()
# {'last_hour': ('-1h', 'now'), 'today': ('@d', 'now'), ...}

Output Formatters

Format data for display:

from splunk_assistant_skills_lib import (
    format_table,
    format_json,
    format_search_results,
    print_success,
    print_warning,
)

# Format as table
print(format_table(results, columns=["host", "count"]))

# Format search results
print(format_search_results(response, output_format="table"))

# Colored output
print_success("Operation completed")
print_warning("Check your configuration")

Configuration File Example

Create .claude/settings.local.json:

{
  "splunk": {
    "default_profile": "production",
    "profiles": {
      "production": {
        "url": "https://splunk.company.com",
        "port": 8089,
        "token": "your-jwt-token",
        "auth_method": "bearer",
        "verify_ssl": true
      },
      "development": {
        "url": "https://splunk-dev.company.com",
        "port": 8089,
        "username": "admin",
        "password": "changeme",
        "auth_method": "basic",
        "verify_ssl": false
      }
    }
  }
}
