SmartInspect Python3 Library

Overview

This API provides Python code execution tracing and diagnostics support via the SmartInspect library. More information on SmartInspect can be found here: https://code-partners.com/offerings/smartinspect/

Warning: Enabling diagnostics tracing could significantly impact application performance, depending on the logging level. For example, a DEBUG logging level will generate a significant amount of trace data compared to an ERROR logging level.

Diagnostic data can be captured in various ways: Real-Time Console, File, Memory, or Text. Diagnostic data is buffered in a message list, and sent by a separate worker thread. This approach ensures that performance impact of the diagnosed application is minimal while diagnostics are enabled.

Diagnostics tracing options can be set via an application configuration settings file.

The Real-Time Console method of sending diagnostic data is the ideal way to diagnose applications that utilize services, such as ASP.NET or Windows Services. For real-time monitoring, diagnostics trace data is sent from your application to the SmartInspect Console viewer over the TCP/IP network. The SmartInspect Console can be started on the same machine where your application is running, or on a different machine that is accessible via the TCP/IP network.

Documentation

  • Documentation is located in the package library under the 'docs' folder; use the index.html as your starting point.

Requirements

  • Python 3.4 or greater (not tested with Python 2).
  • pycryptodome package - used for log file encryption support.
  • pywin32 package - for named-pipe support (Windows platform only - use pip install pywin32 to install manually).

Dependencies

  • SmartInspect Redistributable Console, Version 3.3+.

    The Console Viewer is required to view SmartInspect Log (.sil) formatted files, as well capture packets via the SITcpProtocol or SIPipeProtocol connections. The Console Viewer (aka Redistributable Console) can be downloaded here: https://code-partners.com/offerings/smartinspect/releases/

Quick-Start Sample Code

The following code snippets will get you started with establishing a connection to a logging Console or file. Please refer to the smartinspectpython.sisession.SISession class for all of the various "Logx" methods to log data.

Example 1 - Logging via tcp to a running SmartInspect Console on localhost

# our package imports.
from smartinspectpython.siauto import *

# set smartinspect connections, and enable logging.
SIAuto.Si.Connections = "tcp(host=localhost,port=4228,timeout=5000)"
SIAuto.Si.Enabled = True    # enable logging

# get smartinspect logger reference.
logsi:SISession = SIAuto.Main
logsi.Level = SILevel.Debug   # set Message level logging

# log some test messages.
logsi.LogSystem(SILevel.Debug, "System Information on application startup")
logsi.LogMessage("Hello World has started")

Example 2 - Logging to rotating hourly log files in SmartInspect Console format

# our package imports.
from smartinspectpython.siauto import *

# set smartinspect connections, and enable logging.
# this will keep 24 log files, that rotate every hour.
SIAuto.Si.Connections = "file(filename=\".\\logfiles\\AppLog.sil\", rotate=hourly, maxparts=24, append=true)"
SIAuto.Si.Enabled = True    # enable logging

# get smartinspect logger reference.
logsi:SISession = SIAuto.Main
logsi.Level = SILevel.Debug   # set Message level logging

# log some test messages.
logsi.LogSystem(SILevel.Debug, "System Information on application startup")
logsi.LogMessage("Hello World has started")

Example 3 - Logging to rotating hourly log files in Plain Text format

# our package imports.
from smartinspectpython.siauto import *

# set smartinspect connections, and enable logging.
# this will keep 24 log files, that rotate every hour.
SIAuto.Si.Connections = "text(filename=\".\\logfiles\\AppLog.txt\", rotate=hourly, maxparts=24, append=true)"
SIAuto.Si.Enabled = True    # enable logging

# get smartinspect logger reference.
logsi:SISession = SIAuto.Main
logsi.Level = SILevel.Debug   # set Message level logging

# log some test messages.
logsi.LogSystem(SILevel.Debug, "System Information on application startup")
logsi.LogMessage("Hello World has started")

Change Log

All notable changes to this project are listed here. Detailed changes are listed in the module where the change was made.

Change are listed in reverse chronological order (newest to oldest).

[ 3.0.20 ] - 2023/09/03
  • Changed alpha byte from 0xFF to 0x00 for all color definitions in the SIColors enum class.
  • Changed all Session.LogX method signatures to use the SIColors enum type, or an integer value in ARGB format.
  • Updated internal build processes to use Python Virtual Environment.
[ 3.0.19 ] - 2023/09/01
  • Minor internal naming changes to functions in various modules to conform to Python best-practice naming standards (e.g. use single underscore instead of double underscore for internal methods).
[ 3.0.18 ] - 2023/08/31
  • Major changes to the package! All classes were renamed to start with an "SI" prefix, to avoid naming conflicts with other namespaces.
  • Renamed the KnownColorValues class to SIColors.
  • I was hesitant to do this, as it will cause breaking changes to applications that utilize the package. It was required though, to avoid namespace conflicts with like-named modules in system / other packages.
[ 3.0.17 ] - 2023/07/11
  • Minor internal only changes to build process.
[ 3.0.16 ] - 2023/07/11
  • Changed Session.GetMethodName method to use inspect.stack(0) instead of inspect.stack() to improve performace.
[ 3.0.15 ] - 2023/06/30
  • Changed 'Development Status' to '5 - Production/Stable', and uploaded to Pypi.org site.
[ 3.0.14 ] - 2023/06/28
  • Changed Session class to use temporary logger to capture exception details in LogException method.
[ 3.0.13 ] - 2023/06/23
  • Changed Session LogAssigned method to properly format the LogMessage title value.
[ 3.0.12 ] - 2023/06/17
  • Changed Session.EnterMethod, LeaveMethod to include source file.
  • Added default title to Session.LogAppDomain method.
  • Added exception handling in Session.LogSystem for user name value. It was failing on Windows WSL systems, returning some sort of permissions error.
[ 3.0.11 ] - 2023/06/17
  • Added *args support to Session class methods: LogDebug, LogVerbose, LogMessage, LogWarning, LogException, and LogFatal methods.
[ 3.0.10 ] - 2023/06/15
  • Added Session.LogPngFile, LogPngStream methods for SI Console 3.4+ support.
[ 3.0.9 ] - 2023/06/15
  • Changed the Session.CurrentMethodName, CurrentMethodNameClass, CurrentMethodNameClassNamespace properties to static methods.
[ 3.0.8 ] - 2023/06/09
  • Added InfoEvent event and RaiseInfoEvent methods to SmartInspect and Protocol classes. This allows SmartInspect to convey informational events to interested parties. For example, the SI Console Server banner is available, as well as when a SIConfiguration settings file is changed and reloaded if using SIConfigurationTimer class.
[ 3.0.7 ] - 2023/06/05
  • Documentation updates.
[ 3.0.6 ] - 2023/06/02
  • Documentation updates.
[ 3.0.5 ] - 2023/06/01
  • Fixed an issue with Session.GetMethod() not returning a method name.
[ 3.0.4 ] - 2023/05/31
  • Fixed an error related to using the "pack()" method that was not using the endian format characters (e.g. < >). This was causing packet sizes to be off on non-Windows platforms.
[ 3.0.2 ] - 2023/05/31
  • Added conditional import of pipeprotocol module, as named-pipes are only supported on the Windows platform. This was causing module not found error when trying to execute on non-Windows platforms.
[ 3.0.0 ] - 2023/05/30
  • Version 3 initial release, ported to Python from the SmartInspect for .Net framework.
