Assigning a severity level to a computing service using tenant telemetry data

A method of determining a severity level of a computing service, the method comprising:

• receiving, with an electronic processor, telemetry data associated with one or more tenants of an online service, the online service providing services through a plurality of computing services;
• calculating, with the electronic processor, a number of accesses of each of the plurality of computing services during a predetermined time period, based on the telemetry data by counting each access by a non-synthetic user during the predetermined time period differently than each access by a synthetic user during the predetermined time period;
• for each of the plurality of computing services, assigning, with the electronic processor, a severity level to each computing service based on the number of accesses of each computing service during the predetermined time period relative to the number of accesses of another computing service included in the plurality of computing services during the predetermined time period;
• and
• in response to detecting a failure of one of the plurality of computing services, initiating, with the electronic processor, a response to the failure based on the severity level assigned to the one of the plurality of computing services,
• wherein assigning the severity level to each computing service based on the number of accesses of each computing service during the predetermined time period relative to the number of accesses of another computing service included in the plurality of computing services during the predetermined time period includes calculating a mean of the number of accesses of each of the plurality of computing services and assigning the severity level to each of the plurality of computing services based on a comparison of the number of accesses of each of the plurality of computing services to the mean.

A non-transitory, computer-readable medium storing instructions that, when executed by an electronic processor, perform a set of functions, the set of functions comprising:

• receiving telemetry data associated with one or more tenants of an online service, the online service providing services through a plurality of computing services;
• calculating a number of accesses of each of the plurality of computing services during a predetermined time period, based on the telemetry data;
• for each of the plurality of computing services, assigning a severity level from a plurality of predefined levels to each computing service based on the number of accesses of each computing service during the predetermined time period relative to the number of accesses of another computing service included in the plurality of computing services during the predetermined time period, wherein each plurality of predefined levels defines at least action to take in response to a subsequently-detected failure;
• and
• in response to detecting a failure of one of the plurality of computing services, determining the severity level assigned to the one of the plurality of computing services and initiating the at least one action defined by the severity level assigned to the one of the plurality of computing services,
• wherein the severity level assigned to at least one of the plurality of computing services is a first severity level associated with first operating condition of the at least one of the plurality of computing services and the set of functions further comprising assigning a second severity level to the at least one of the plurality of computing services, the second severity level associated with a second operating condition of the at least one of the plurality of computing services.

A system for determining a severity level of a computing service, the system comprising:

• an electronic processor configured to
• receive telemetry data associated with one or more tenants of an online service, the online service providing services through a plurality of computing services;
• calculate, based on the telemetry data, a number of accesses of each of the plurality of computing services during a predetermined time period by counting each access by a unique user during the predetermined time period;
• for each of the plurality of computing services, assign a severity level to each computing service based on the number of accesses of each computing service during the predetermined time period relative to the number of accesses of another computing service included in the plurality of computing services during the predetermined time period;
• and
• in response to detecting a failure of one of the plurality of computing services, initiate a response to the failure based on the severity level assigned to the one of the plurality of computing services,
• wherein the electronic processor is configured to assign the severity level to each computing service based on the number of accesses of each computing service during the predetermined time period relative to the number of accesses of another computing service included in the plurality of computing services during the predetermined time period by calculating a medium of the number of accesses of each of the plurality of computing services and assigning the severity level to each of the plurality of computing services based on a comparison of the number of accesses of each of the plurality of computing services to the medium.
