Dynamic configuration of entity polling using network topology and entity status

A computer configured to access a storage device, the computer comprising:

• a processor;
• and
• a non-transitory, computer-readable storage medium storing computer-readable instructions that when executed by the processor cause the computer to perform:
• polling a plurality of entities in a network for status information at a first polling frequency;
• receiving a fault indicator associated with a function of a web application hosted by an entity in the network;
• mapping the fault indicator to a particular node in a network topology, the network topology comprising nodes corresponding to entities in the plurality of entities and edges describing relationships and dependencies between the plurality of entities, wherein the particular node corresponds to the associated entity for the fault indicator;
• determining a set of related nodes that would be affected by or would be a potential cause of the fault indicator based on (1) connections to the particular node in the network topology, (2) whether a type of error signified by the fault indicator would impact certain connections or the functioning of a subset of the related nodes, and (3) whether the edge between the particular node and any related nodes describes a service-relationship associated with the functioning of the web application;
• and
• in response to receiving the fault indicator, polling corresponding entities for the set of related nodes for status information at a second polling frequency while polling corresponding entities for unrelated nodes at the first polling frequency, the second polling frequency being greater than the first polling frequency.

A computer program product comprising:

• a computer-readable storage medium having computer-readable program code embodied therewith, the computer-readable program code comprising:
• computer-readable program code configured to poll a plurality of entities in a network for status information at a first polling frequency;
• computer-readable program code configured to receive a fault indicator associated with a function of a web application hosted by an entity in the network;
• computer-readable program code configured to map the fault indicator to a particular node in a network topology, the network topology comprising nodes corresponding to entities in the plurality of entities and edges describing relationships and dependencies between the plurality of entities, wherein the particular node corresponds to the associated entity for the fault indicator;
• computer-readable program code configured to determine a set of related nodes that would be affected by or would be a potential cause of the fault indicator based on (1) connections to the particular node in the network topology, (2) whether a type of error signified by the fault indicator would impact certain connections or the functioning of a subset of the related nodes, and (3) whether the edge between the particular node and any related nodes describes a service-relationship associated with the function of the web application;
• and
• computer-readable program code configured to poll corresponding entities for the set of related nodes for status information at a second polling frequency, the second polling frequency being greater than the first polling frequency.
