Spylunking - Drill down into your logs with an integrated, colorized logger with search tools. Includes a Splunk sandbox running in docker.
Project description
Spylunking - Splunk + Python Logging
Drill down into your logs with an integrated, colorized logger and search tools set up with the included Splunk docker sandbox.
This repository creates Splunk-ready, colorized Python loggers that work with a Splunk TCP Port or the Splunk HEC REST API. Both of these endpoints are automatically set up for use with the included docker container.
Sample Log Handlers
Depending on your application’s use case you can use one of the included Python logging handlers:
The log publishing and search tools support using existing Splunk tokens or logging in using the configured user and password arguments or from environment variables.
Sample Log Config JSON Files
Here are the sample logging config JSON files:

Getting Started
Clone the repo
git clone https://github.com/jay-johnson/spylunking.git spylunking cd spylunking
Install the pip
pip install spylunking
If you want to develop use this command:
pip install -e .
Start the Splunk docker container
./run-splunk-in-docker.sh
Get a Splunk User Token
By default the container creates a user with the credentials:
username: trex password: 123321
get_splunk_token.py 955324da-742b-43d4-9746-bcbedf6ae7f4
Set the Splunk Environment Variables
export SPLUNK_INDEX=antinex export SPLUNK_TOKEN=955324da-742b-43d4-9746-bcbedf6ae7f4
Please wait at least 30 seconds while the container is getting ready. You may see output like this when the splunk container is not ready yet or stops running:
get_splunk_token.py Traceback (most recent call last): File "<redacted path for doc>", line 171, in _new_conn (self._dns_host, self.port), self.timeout, **extra_kw) File "<redacted path for doc>", line 79, in create_connection raise err File "<redacted path for doc>", line 69, in create_connection sock.connect(sa) ConnectionRefusedError: [Errno 111] Connection refused
Publishing Logs to Splunk using the Spylunking Logger
Below is a video showing how to tag your application’s logs using the LOG_NAME environment variable. Doing this allows you to quickly find them in Splunk using the included sp command line tool.
Commands from the video:
Set an Application Log Name
export LOG_NAME=payments
Search for Logs in Splunk
sp -q 'index="antinex" AND name=payments | head 5 | reverse' No matches for search={ "search": "search index=\"antinex\" AND name=payments | head 5 | reverse" } response={ "init_offset": 0, "messages": [], "post_process_count": 0, "preview": false, "results": [] }

Get Splunk Logs from the Command Line Tool
Use the command line tool: sp to search for recent logs.
Set environment variables:
export SPLUNK_ADDRESS="splunkenterprise:8088" export SPLUNK_API_ADDRESS="splunkenterprise:8089" export SPLUNK_PASSWORD="123321" export SPLUNK_USER="trex"
Run the tool:
sp
Which will log something like:
sp - INFO - No matches for search={ "search": "search index=\"antinex\" | head 10" } sp - INFO - done
Write Splunk Logs
By default, the container creates a Splunk index called: antinex with a user token for the user trex to search the index. Once the Splunk container is running, you can use the included test_logging.py script to create sample logs to verify the Splunk logging integration is working. The default logger will send logs over TCP using the TCP Splunk Publisher. To change this, you can export the optional environment variable SHARED_LOG_CFG to the absolute path of another logging config JSON file like:
export SHARED_LOG_CFG=<absolute path to logging config JSON file>
Send logs using the command: test_logging.py
test_logging.py 2018-06-24 01:07:36,378 - testingsplunk - INFO - testing INFO message_id=ce9c91dc-3af9-484d-aeb0-fc09194bb42e 2018-06-24 01:07:36,379 - testingsplunk - ERROR - testing ERROR message_id=9227cc2f-f734-4b99-8448-117776ef6bff 2018-06-24 01:07:36,379 - testingsplunk - CRITICAL - testing CRITICAL message_id=7271a65d-d563-4231-b24a-b17364044818 2018-06-24 01:07:36,379 - testingsplunk - WARNING - testing WARN message_id=54063058-dba1-47ee-a0ab-d654b3140e55 2018-06-24 01:07:36,379 - testingsplunk - ERROR - Testing EXCEPTION with ex=Throw for testing exceptions message_id=c1e100f4-202d-48ac-9803-91c4f02c9a92
Get the Test Splunk Logs using the Command Line Tool
The command line tool called sp is included with the pip on install. When you run it, it will return the most recent logs from the index (antinex by default) and print them to stdout.
sp
If you want to pull logs from splunk with user credentials (SPLUNK_USER and SPLUNK_PASSWORD as environment variables works too):
sp -u trex -p 123321 -a splunkenterprise:8089
Running sp should return something like these test logs:
sp -u trex -p 123321 -a splunkenterprise:8089 sp - ERROR - testingsplunk.testingsplunk 2018-06-24 01:07:36,379 - Testing EXCEPTION with ex=Throw for testing exceptions message_id=c1e100f4-202d-48ac-9803-91c4f02c9a92 dc= env= source=/opt/spylunking/spylunking/scripts/test_logging.py line=41 ex=None sp - CRITICAL - testingsplunk.testingsplunk 2018-06-24 01:07:36,379 - testing CRITICAL message_id=7271a65d-d563-4231-b24a-b17364044818 dc= env= source=/opt/spylunking/spylunking/scripts/test_logging.py line=31 ex=None sp - ERROR - testingsplunk.testingsplunk 2018-06-24 01:07:36,379 - testing ERROR message_id=9227cc2f-f734-4b99-8448-117776ef6bff dc= env= source=/opt/spylunking/spylunking/scripts/test_logging.py line=29 ex=None sp - INFO - testingsplunk.testingsplunk 2018-06-24 01:07:36,378 - testing INFO message_id=ce9c91dc-3af9-484d-aeb0-fc09194bb42e dc= env= source=/opt/spylunking/spylunking/scripts/test_logging.py line=27 ex=None sp - INFO - done

Running Stats Commands like Counting Log Matches
After running a few million logs through the Splunk container you can count the number of matches using sp:
sp -q 'index="antinex" | stats count' { "count": "9261227" }
Splunk Client Load Testing
If you are looking to tune your Splunk client logging performance, then please check out the included load tester to validate the deployed configuration will not fail to publish log messages (if that is required for your client).
Before using this in production, please note it is possible to overflow the current python queues during something like an extended Splunk maintenance window or if the client is publishing logs over an unreliable network connection. The default configuration is only going to queue up to 1 million log messages before starting to drop new logs. Another way to test this is if your application is writing logs faster than the Splunk REST API can keep up, then eventually it will overflow the queue’s default depth. If you are concerned about not losing log messages, then the logger should set a flush interval of 0 to disable the asynchronous, threaded queue support. This will put the client logger into a blocking mode and ensure there are no missed log messages. Please consider that this change will only create blocking log publishers where the retry_count and timeout values should be tuned to your application’s needs to prevent slow application performance while waiting on the client’s HTTP requests to acknowledge each log was received.
Here is how to start a single process load tester:

Logging to Splunk from a Python Shell
Here are python commands to build a colorized, splunk-ready python logger. On startup, the logger will authenticate with splunk using the provided credentials. Once authenticated you can use it like a normal logger.
python -c '\
import json;\
from spylunking.log.setup_logging import build_colorized_logger;\
import spylunking.search as sp;\
from spylunking.ppj import ppj;\
print("build the logger");\
log = build_colorized_logger(\
name="spylunking-in-a-shell",\
splunk_user="trex", \
splunk_password="123321");\
print("import the search wrapper");\
res = sp.search(\
user="trex",\
password="123321",\
address="splunkenterprise:8089",\
query_dict={\
"search": "search index=\"antinex\" | head 1"\
});\
print("pretty print the first record in the result list");\
log.critical("found search results={}".format(ppj(json.loads(res["record"]["results"][0]["_raw"]))))'
Here is sample output from running this command:

Publishing Logs to a Remote Splunk Server
Set up the environment variables:
export SPLUNK_API_ADDRESS="splunkenterprise:8089" export SPLUNK_ADDRESS="splunkenterprise:8088" export SPLUNK_USER="trex" export SPLUNK_PASSWORD="123321"
Run the test tool to verify logs are published:

Set up a Logger
There are multiple loggers avaiable depending on the type of logger that is needed.
Simple Logger
Build a simple, no dates colorized logger that prints just the message in colors and does not publish logs to Splunk using:
from spylunking.log.setup_logging import simple_logger
log = simple_logger()
log.info('simple logger example')
simple logger example
No Date Colorized Logger
Build a colorized logger that preserves the parent application name and log level without a date field and does not publish logs to Splunk using:
from spylunking.log.setup_logging import no_date_colors_logger
log = no_date_colors_logger(name='app-name')
log.info('no date with colors logger example')
app-name - INFO - no date with colors logger example
Test Logger
The test logger is for unittests and does not publish to Splunk.
from spylunking.log.setup_logging import test_logger
log = test_logger(name='unittest logger')
log.info('unittest log line')
2018-06-25 16:01:50,118 - using-a-colorized-logger - INFO - colorized logger example
Console Logger
The console logger is the same as the build_colorized_logger which can be created with authenticated Splunk-ready logging using:
from spylunking.log.setup_logging import build_colorized_logger
log = build_colorized_logger(name='using-a-colorized-logger')
log.info('colorized logger example')
2018-06-25 16:47:54,053 - unittest logger - INFO - unittest log line
Define Custom Fields for Splunk
You can export a custom JSON dictionary to send as JSON fields for helping drill down on log lines using this environment variable.
export LOG_FIELDS_DICT='{"name":"hello-world","dc":"k8-splunk","env":"development"}'
Or you can export the following environment variables if you just want a couple set in the logs:
export LOG_NAME=<application log name> export DEPLOY_CONFIG=<PaaS/CaaS deployment config name> export ENV_NAME<deployed environment name>
Log some new test messages to Splunk:
test_logging.py 2018-06-25 20:48:51,367 - testingsplunk - INFO - testing INFO message_id=0c5e2a2c-9553-4c8a-8fff-8d77de2be78a 2018-06-25 20:48:51,368 - testingsplunk - ERROR - testing ERROR message_id=0dc1086d-4fe4-4062-9882-e822f9256d6f 2018-06-25 20:48:51,368 - testingsplunk - CRITICAL - testing CRITICAL message_id=0c0f56f2-e87f-41a0-babb-b71e2b9d5d5a 2018-06-25 20:48:51,368 - testingsplunk - WARNING - testing WARN message_id=59b099eb-8c0d-40d0-9d3a-7dfa13fefc90 2018-06-25 20:48:51,368 - testingsplunk - ERROR - Testing EXCEPTION with ex=Throw for testing exceptions message_id=70fc422d-d33b-4a9e-bb51-ed86aa0a02f9
Once published, you can search for these new logs using those new JSON fields with the sp search tool. Here is an example of searching for the logs with the application log name hello-world:
