Architecture

Trycatch consists of four parts:

• backend server Implemented by golang, providing APIs service and Push Notification service etc. .

• frontend web app Implemented by reactjs, providing intereactive user interface for administrator or normal user.

• mobile app Another way to browse activity and report by real-time through Push Notification Server, supporting iOS and Android mobile.

• diaper(custom flume HttpSink to monitor exception) Aggregating exception log data by Taildir Source of Apache Flume, and sending log data as a POST body to BackendServer by HTTP Sink of Apache Flume.

Quick Start with a demo

1. Prerequisite

• 64bit OS, Linux/Unix/Mac
• 64bit JDK 1.8+
• Available network connect

2. Download demo

Download demo

• copy demo.tar.gz to a directory and tar -zxvf demo.tar.gz
• run java -jar ./generror-1.0-SNAPSHOT-jar-with-dependencies.jar
• cd apache-flume-1.8.0-bin/bin, then run ./diaper.h

3. Sign in TryCatch

• Open http://danceyoung.github.io/trycatchfinally/ or iOS app [TryCatch] sign in with a account that username is danceyoung@hotmail.com, password is diaper
• Click the project "TryCatch Project Test", then browse the bug list and charts

Developing custom components

• diaper-flume-conf.properties

A config file that watch the specified files, and tail them in nearly real-time once detected new lines appended to the each files. Please link Apache Flume official doc http://flume.apache.org/releases/content/1.9.0/FlumeUserGuide.html#taildir-source You may care about agent.sources.loggerSource.filegroups to config the logfiles wathed.

• Manage the demo project

Copy content in the 3 step, then you need to write the value to your application.

• Your backend application

Assuming the jar of demo is your backend application, you have to do is adding a json string to your log content, the json string contains ttf_access_token and ttf_log_timestamp properties.
ttf_access_token is the value copied in the part of "Manage the demo project",
ttf_log_timestamp is the number of milliseconds of now date. The source code is in demo source code
