On this weblog, we’ll dive into how giant language fashions, generative AI, and the Triangle System assist us leverage automation and suggestions loops for extra environment friendly incident administration.
Excessive service high quality is essential to the reliability of the Azure platform and its a whole lot of companies. Repeatedly monitoring the platform service well being allows our groups to promptly detect and mitigate incidents that will affect our prospects. Along with automated triggers in our system that react when thresholds are breached and customer-report incidents, we make use of Synthetic Intelligence-based Operations (AIOps) to detect anomalies. Incident administration is a posh course of, and it may be a problem to handle the dimensions of Azure, and the groups concerned to resolve an incident effectively and successfully with the wealthy area data wanted. I’ve requested our Azure Core Insights Staff to share how they make use of the Triangle System utilizing AIOps to drive faster time to decision to finally profit person expertise.

Optimizing incident administration
Incidents are managed by designated accountable people (DRIs) who’re tasked with investigating incoming incidents to handle how and who must resolve the incident. As our product portfolio expands, this course of turns into more and more complicated because the incident logged towards a selected service might not be the foundation trigger and will stem from any variety of dependent companies. With a whole lot of companies in Azure, it’s practically unimaginable for anybody particular person to have area data in each space. This presents a problem to the effectivity of guide prognosis, leading to redundant assignments and prolonged Time to Mitigate (TTM). On this weblog, we’ll dive into how giant language fashions, generative AI, and the Triangle System assist us leverage automation and suggestions loops for extra environment friendly incident administration.
AI brokers have gotten extra mature because of the bettering reasoning means of enormous language fashions (LLMs), enabling them to articulate all of the steps concerned of their thought processes. Historically, LLMs have been used for generative duties like summarization with out leveraging their reasoning capabilities for real-world decision-making. We noticed a use case for this functionality and constructed AI brokers to make the preliminary task choices for incidents, saving time and decreasing redundancy. These brokers use LLMs as their mind, permitting them to suppose, cause, and make the most of instruments to carry out actions independently. With higher reasoning fashions, AI brokers can now plan extra successfully, overcoming earlier limitations of their means to “suppose” comprehensively. This method won’t solely enhance effectivity but additionally improve the general person expertise by making certain faster decision of incidents.
Introducing the Triangle System
The Triangle System is a framework that employs AI brokers to triage incidents. Every AI agent represents the engineers of a particular staff and is encoded with area data of the staff to triage points. It has two superior capabilities: Native Triage and International Triage.
Native Triage System
The Native Triage System is a single agent framework that makes use of a single agent to signify every staff. These single brokers present a binary choice to both settle for or reject an incoming incident on behalf of its staff, based mostly on historic incidents and current troubleshooting guides (TSGs). TSGs are a set of tips that engineers doc to troubleshoot frequent patterns of points. These TSGs are used to coach the agent to just accept or reject incidents and supply the reasoning behind the choice. Moreover, the agent can suggest the staff to which the incident ought to be transferred to, based mostly on the TSGs.
As proven in Determine 1, the Native Triage system begins when an incident enters a service staff’s incident queue. Based mostly on the coaching from historic incidents and TSGs, the one agent employs Generative Pretrained Transformer (GPT) embeddings to seize the semantic meanings of phrases and sentences. Semantic distillation includes extracting semantic info from the incident that’s intently associated to incident being triaged. The one agent will then resolve to just accept or reject the incident. If accepted, the agent will present the reasoning, and the incident will likely be handed off to an engineer to assessment. If rejected, the agent will both ship it again to the earlier staff, switch to a staff indicated by the TSG, or maintain it within the queue for an engineer to resolve.
Determine 1: Native Triage system workflow
The Native Triage system has been in manufacturing in Azure since mid-2024. As of Jan 2025, 6 groups are in manufacturing with over 15 groups within the strategy of onboarding. The preliminary outcomes are promising, with brokers attaining 90% accuracy and one staff noticed a discount of their TTM of 38%, considerably decreasing the affect to prospects.
International Triage System
The International Triage System goals to route the incident to the right staff. The system coordinates throughout all the one brokers through a multi-agent orchestrator to establish the staff that the incident ought to be routed to. As proven in Determine 2, the multi agent orchestrator selects appropriate staff candidates for the incoming incident, negotiates with every agent to search out the right staff, additional decreasing TTM. This can be a related method to sufferers coming into the emergency room, the place the nurse briefly assesses signs and directs every affected person to their specialist. As we additional develop the International Triage System, brokers will proceed to broaden their data and enhance their decision-making skills, vastly bettering not solely the person expertise by mitigating buyer points shortly but additionally bettering developer productiveness by decreasing guide toil.

Wanting ahead
We plan to broaden protection by including extra brokers from completely different groups that may broaden the data base to enhance the system. Among the methods we plan to do that embrace:
- Prolong the incident triage system to work for all groups: By extending the system to all groups, we goal to boost the general data of the system enabling it to deal with a variety of points. Making a unified method to incident administration would result in extra environment friendly and constant dealing with of incidents.
- Optimize the LLMs to swiftly establish and suggest options by correlating error logs with the precise code segments chargeable for the problem: Optimizing LLMs to shortly establish, correlate, and suggest options will considerably velocity up the troubleshooting course of. It permits the system to supply exact suggestions, decreasing the time engineers spend on debugging and resulting in sooner decision of points for patrons.
- Broaden auto mitigating identified points: Implementing an automatic system to mitigate identified points will scale back TTM bettering buyer expertise. This may also scale back the variety of incidents that require guide intervention, enabling engineers to give attention to delighting prospects.
We first launched AIOps as a part of this weblog collection in February 2020 the place we highlighted how integrating AI into Azure’s cloud platform and DevOps processes enhances service high quality, resilience, and effectivity via key options together with {hardware} failure prediction, pre-provisioning companies, and AI-based incident administration. AIOps continues to play a important position as we speak to foretell, defend, and mitigate failures and impacts to the Azure platform and enhance buyer expertise.
By automating these processes, our groups are empowered to shortly establish and deal with points, making certain a high-quality service expertise for our prospects. Organizations seeking to improve their very own service reliability and developer productiveness can achieve this by integrating AI brokers into their incident administration processes designed within the Triangle System.
