Determining the level of availability of a computing resource

A computer-readable medium having computer-executable instructions stored thereon which, when executed by a computer, cause the computer to:

• determine whether a start event occurred without a corresponding stop event;
• determine an outage time for a computing resource by determining an amount of time between one or more stop events and one or more start events for the computing resource during a period of time, wherein the outage time is computed as the time equal to the time period between a previous availability calculation and the time of the start event in response to determining that a start event occurred without a corresponding stop event;
• and
• calculate a level of availability for the computing resource during the period of time based upon the determined outage time.

A method for determining the level of availability of a computing resource, the method comprising:

• collecting data relating to the availability of the computing resource;
• determining whether no start or stop events for the computing resource occurred during the time period;
• in response to determining that no start or stop events occurred for the computing resource during the time period, determining whether the agent for the computing resource was operating during the time period;
• processing the collected data to determine an outage time for the computing resource during a period of time by setting the outage time for the time period to zero in response to determining that the agent was operating during the time period and setting the outage time for the time period equal to the entire time period in response to determining that the agent was not operating during the time period;
• and
• calculating the level of availability for the computing resource during the period of time based upon the determined outage time.
