Rebooting timing adjustment for improved performance

A computer program product comprising:

• a non-transitory computer readable storage medium readable by one or more processors and storing instructions for execution by the one or more processors for performing a method comprising:
• detecting, by one or more processors, at a given time, a vulnerability, wherein addressing the vulnerability requires applying a patch to a system and re-booting the system, wherein the patch is available for application to the system for a finite window of time;
• based on detecting the vulnerability, determining whether to reboot the system within the finite window of time, the determining comprising:
• obtaining, by the one or more processors, identifiers of tasks executing in the system at the given time, wherein the finite window of time comprises the finite window of time, wherein the tasks comprise direct user tasks, and wherein the tasks do not comprise inner system processes;
• based on obtaining the identifiers, obtaining, by the one or more processors, a task cost of each task of the tasks, at the given time;
• determining, by the one or more processors, based on the task costs associated with the tasks, a re-boot cost for re-booting the system within the finite window of time, wherein the re-boot cost for rebooting the system within the finite window of time is lower than a re-boot cost for rebooting the system outside of the finite window of time;
• determining, by the one or more processors, a system cost for not re-booting the system within the finite window of time;
• and
• comparing, by the one or more processors, the re-boot cost to the system cost to determine whether to re-boot the system within the finite window of time in response to the detecting.

A system comprising:

• one or more memories;
• one or more processors in communication with the one or more memories;
• and
• program instructions executable by the one or more processors via the one or more memories to perform a method, the method comprising:
• detecting, by one or more processors, at a given time, a vulnerability, wherein addressing the vulnerability requires applying a patch to a system and re-booting the system, wherein the patch is available for application to the system for a finite window of time;
• based on detecting the vulnerability, determining whether to reboot the system within the finite window of time, the determining comprising:
• obtaining, by the one or more processors, identifiers of tasks executing in the system at the given time, wherein the finite window of time comprises the finite window of time, wherein the tasks comprise direct user tasks, and wherein the tasks do not comprise inner system processes;
• based on obtaining the identifiers, obtaining, by the one or more processors, a task cost of each task of the tasks, at the given time;
• determining, by the one or more processors, based on the task costs associated with the tasks, a re-boot cost for re-booting the system within the finite window of time, wherein the re-boot cost for rebooting the system within the finite window of time is lower than a re-boot cost for rebooting the system outside of the finite window of time;
• determining, by the one or more processors, a system cost for not re-booting the system within the finite window of time;
• and
• comparing, by the one or more processors, the re-boot cost to the system cost to determine whether to re-boot the system within the finite window of time in response to the detecting.
