Abstract
A method, apparatus and system for improving failover within a high-availability computer system are provided. The method includes obtaining one or more parameters associated with a disaster recovery protocol of at least one resource of any of the first cluster, second cluster and high-availability computer system. The method also includes monitoring one or more states of the parameters. The method further includes detecting, as a function of the parameters and states, one or more anomalies of any of the first cluster, second cluster and high-availability computer system, wherein the anomalies are types that impact the failover. These anomalies may include anomalies associated with the disaster-recovery protocols within the first and/or second clusters (“intra-cluster anomalies”) and/or anomalies among the first and second clusters (“inter-cluster anomalies”). The method further includes generating an alert in response to detecting one or more of the anomalies.
