By collecting and aggregating data attribute values across multiple components of a content delivery system and comparing against baselines for points of inspection, network performance diagnosis and root-cause analysis may be prioritized based on impact on content delivery. Recommended courses of action may be determined and provided based on the tracked network performance analysis at diagnosis points. ## Claims ### Claim 1 A method, comprising: determining a diagnosis point associated with a component of a content delivery system; receiving data associated with a version of the component of the content delivery system; generating a metric associated with the diagnosis point based on the data, wherein the metric comprises a first composite metric, the first composite metric comprising one or more data attributes associated with one or more sub-components of the component; responsive to the metric exceeding a threshold associated with an impact to the content delivery system, generating a recommendation comprising one or more parameter modifications to the diagnosis point associated with the component, wherein the threshold associated with the impact comprises a second composite metric associated with the one or more sub-components of the component. ### Claim 2 (depends on 1) The method as recited in claim 1, wherein the component comprises an agent on a user device of the content delivery system and the data is received from the agent. ### Claim 3 (depends on 1) The method as recited in claim 1, wherein the component comprises a proxy server communicatively coupled to a server and the data is received from the proxy server, wherein the data is associated with the server. ### Claim 4 (depends on 1) The method as recited in claim 1, wherein the metric comprises a performance metric comparing a data attribute of the data to a baseline. ### Claim 5 A non-transitory computer readable medium storing a program of instructions that is executable by a device to perform a method, the method comprising: determining a diagnosis point associated with a component of a content delivery system; receiving data associated with a version of the component of the content delivery system; generating a metric associated with the diagnosis point based on the data, wherein the metric comprises a first composite metric, the first composite metric comprising one or more data attributes associated with one or more sub-components of the component; responsive to the metric exceeding a threshold associated with an impact to the content delivery system, generating a recommendation comprising one or more parameter modifications to the diagnosis point associated with the component, wherein the threshold associated with the impact comprises a second composite metric associated with one or more sub-components of the component. ### Claim 6 (depends on 5) The non-transitory computer readable medium as recited in claim 5, wherein the component comprises an agent on a user device of the content delivery system and the data is received from the agent. ### Claim 7 (depends on 5) The non-transitory computer readable medium as recited in claim 5, wherein the component comprises a proxy server communicatively coupled to a server and the data is received from the proxy server, wherein the data is associated with the server. ### Claim 8 (depends on 5) The non-transitory computer readable medium as recited in claim 5, wherein the metric comprises a performance metric comparing a data attribute of the data to a baseline. ### Claim 9 An apparatus, comprising: a subsystem, implemented at least partially in hardware, that determines a diagnosis point associated with a component of a content delivery system; a subsystem, implemented at least partially in hardware, that receives data associated with a version of the component of the content delivery system; a subsystem, implemented at least partially in hardware, that generates a metric associated with the diagnosis point based on the data, wherein the metric comprises a first composite metric, the first composite metric comprising one or more data attributes associated with one or more sub-components of the component; a subsystem, implemented at least partially in hardware, that responsive to the metric exceeding a threshold associated with an impact to the content delivery system, generates a recommendation comprising one or more parameter modifications to the diagnosis point associated with the component, wherein the threshold associated with the impact comprises a second composite metric associated with one or more sub-components of the component. ### Claim 10 (depends on 9) The apparatus as recited in claim 9, wherein the component comprises an agent on a user device of the content delivery system and the data is received from the agent. ### Claim 11 (depends on 9) The apparatus as recited in claim 9, wherein the component comprises a proxy server communicatively coupled to a server and the data is received from the proxy server, wherein the data is associated with the server. ### Claim 12 (depends on 9) The apparatus as recited in claim 9, wherein the metric comprises a performance metric comparing a data attribute of the data to a baseline.
