Abstract
Methods and apparatus to provide failure detection are disclosed herein. An example method includes executing, via a plurality of computing nodes, first fenced computing operations; storing a count of issued data operations resulting from the first fenced computing operations; and determining whether a failure condition exists in the plurality of computing nodes by comparing the count of issued data operations to the count of performed data operations resulting from the first fenced computing operations.
Claims22
A method, comprising:
- executing, via a plurality of computing nodes, first fenced computing operations;
- storing a count of issued data operations resulting from the first fenced computing operations;
- and
- determining whether a failure condition exists in the plurality of computing nodes by comparing the count of issued data operations to a count of performed data operations resulting from the first fenced computing operations.
A tangible computer readable storage medium having instructions stored thereon that, when executed, cause a machine to at least:
- execute, via a plurality of computing nodes, first fenced computing operations;
- store a count of issued data operations resulting from the first fenced computing operations;
- and
- determine whether a failure condition exists in the plurality of computing nodes by comparing the count of issued data operations to a count of performed data operations resulting from the first fenced computing operations.
A system, comprising:
- a plurality of first computing nodes to cooperate to perform first fenced computing operations, to store respective first numbers of issued data operations resulting from the first fenced computing operations, and to monitor second numbers of performed data operations resulting from the first fenced computing operations;
- and
- a second computing node to determine a count of issued data operations based on the first numbers of issued data operations, to determine a count of performed data operations based on the second numbers, and to determine whether a failure condition exists by comparing the count of issued data operations to the count of performed data operations.
