Api failure monitor and impact mitigator

A system, comprising:

• a processor;
• a computer-readable memory in circuit communication with the processor;
• a computer-readable storage medium in circuit communication with the processor;
• and
• wherein the processor executes program instructions stored on the computer-readable storage medium via the computer-readable memory and thereby:
• in response to determining that an application programming interface call made in response to a first request for the call has failed and that no fail entry has been set for the call, increments a fail count value and sets a fail entry for the call, wherein the fail entry comprises a fail response generated by the failure of the first request for the call, and wherein no other fail entry is set for the call;
• in response to determining that the call has failed in response to a second request for the call, wherein the second request is subsequent to the first request, determines whether the incremented fail count value meets a limit value;
• in response to determining that the incremented fail count value meets the limit value, sets a paused timestamp value for the fail entry;
• and
• in response to each of any additional requests for the call occurring within a pause period of time from the paused timestamp value, pauses making the call in response to any of the additional requests and returns the fail entry set for the call in satisfaction of said any additional requests.

A computer program product, comprising:

• a computer-readable storage medium having computer-readable program code embodied therewith, wherein the computer-readable storage medium is not a transitory signal per se, the computer-readable program code comprising instructions for execution by a processor that cause the processor to:
• in response to determining that an application programming interface call made in response to a first request for the call has failed and that no fail entry has been set for the call, increment a fail count value and set a fail entry for the call, wherein the fail entry comprises a fail response generated by the failure of the first request for the call, and wherein no other fail entry is set for the call;
• in response to determining that the call has failed in response to a second request for the call, wherein the second request is subsequent to the first request, determine whether the incremented fail count value meets a limit value;
• in response to determining that the incremented fail count value meets the limit value, set a paused timestamp value for the fail entry;
• and
• in response to each of any additional requests for the call occurring within a pause period of time from the paused timestamp value, pause making the call in response to any of the additional requests and return the fail entry set for the call in satisfaction of said any additional requests.
