Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

ICAPRG503A - Debug and monitor applications

What evidence can you provide to prove your understanding of each of the following citeria?

Implement a framework for logging and error handling

  1. Determine the logging framework for writing text messages at a certain level or priority to log files or sending data to monitoring applications
  2. Create a custom event log for an application
  3. Analyse the logs to check the state of the running application

Monitor the application performance

  1. Identify and use profiling tools to verify the parts of the system that consume the most resources, such as random access memory (RAM), central processing unit (CPU) and time
  2. Analyse performance issues and apply changes to improve the performance of the application

Instructions to Assessors

Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Evidence of the ability to:

create error logging framework topersist error logs, debug and trace an application, and plan a performance-monitoring strategy

use debugging techniques and tools, and profiling tools and analyse performance issues.

Context of and specific resources for assessment

Assessment must ensure access to:

client and server system

sufficient privileges to access and use performance monitoring tools in client and server systems

debugging tools

specific tools and licences, depending on particular platform

appropriate learning and assessment support when required

modified equipment for people with special needs.

Method of assessment

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

written or verbal questioning of debugging, diagnostics and monitoring strategy

evaluation of candidate’s logging framework and custom event log for an application

direct observation of candidate using an integrated development environment (IDE) for code development and debugging and the monitoring applications.

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, where appropriate.

Assessment processes and techniques must be culturally appropriate, and suitable to the communication skill level, language, literacy and numeracy capacity of the candidate and the work being performed.

Indigenous people and other people from a non-English speaking background may need additional support.

In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge.

Required Skills and Knowledge

Required skills

analytical skills to:

evaluate and compare results from different profiling tools

evaluate log file information and develop solutions as a result of analysis

communication skills to recommend an approach to debugging and performance issues

initiative and enterprise skills to identify potential improvements to the application performance

literacy skills to:

read log files

write log messages

numeracy skills to read and interpret the monitoring applications data

research skills to keep up-to-date with monitoring and debugging technologies and tools

technical skills to:

use software development tools

write code to create custom event log.

Required knowledge

basic knowledge of:

computer hardware, networking and components

database-management systems

object-oriented programming

open-source development tools

maths at a basic level

procedures for developing small-size applications

software development life cycle (SDLC).

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance.
