SIA - SRE Incident Assistant

SIA is a new incident management tool that reads from event sources and recommends courses of action that help mitigate incidents quickly. SIA can read from nearly any event stream or ticketing system, and works with many live site response models.

The problem

Software systems are only as effective as they are reliable. As online services grow larger and more complex, the potential complexity of failure modes increases as well. Measures that reduce chances of catastrophic failure (such as redundancy, automated mitigation, and throttling/retry logic) are very effective at preventing outages caused by simple bugs and hardware failures, but cannot (yet) adjust to prevent types of problems that weren't anticipated when those measures were designed. As organizations automate away the need for humans to intervene in cases of simple failures, human incident responders are left to deal with the most complex and pervasive outages. Existing tools are sufficient for most incidents, but fall short in critical situations:

• Grey failures, capacity tipping points, and other cases where multiple systems interact in unanticipated ways to produce problems without a known path to mitigation, especially when changes to code or configuration may result in more impact to users than the problem itself.
• Situations where multiple teams are simultaneously investigating outages, some (but not all) of which share a root cause.
• Long-running issues that require coordination between multiple teams and handoff between shifts within each team over the course of several days or weeks.
• Major security issues such as Heartbleed and WannaCry that require immediate updates across significant portions of an organization's infrastructure.
• Disasters that cause extended or permanent loss of significant physical capacity, including undersea fiber cuts and loss of data center buildings.

The solution

The SRE Incident Assistant (SIA) is designed to facilitate coordination, communication, and mitigation activities in 'worst case scenario' outages while gathering data for use in postmortem and process improvement.

Quick Start

• Install prerequisites
  • For Windows Users, the PowerShell script (installEventUI.ps1) can help installing the prerequisites, as well as cloning the UI repos.
• Clone the repos:
  • Gateway: git clone https://github.com/Azure/Sia-Gateway
  • UI: git clone https://github.com/Azure/Sia-EventUi
• Init the submodule from the gateway root directory
  • git submodule init
  • git submodule update --remote
• Update the configurations
• Launch Gateway form Visual Studio 2017 or Visual Studio Code
• Start UI with npm
  • npm start
• Open http://localhost:3000 in your browser, and voilà
