A sequential counter that Amazon Route 53 sets to 1 when you create a health check and increments by 1 each time you update settings for the health check.

We recommend that you use GetHealthCheck or ListHealthChecks to get the current value of HealthCheckVersion for the health check that you want to update, and that you include that value in your UpdateHealthCheck request. This prevents Amazon Route 53 from overwriting an intervening update:

f the value in the UpdateHealthCheck request matches the value of HealthCheckVersion

in the health check, Amazon Route 53 updates the health check with the new settings.

If the value of HealthCheckVersion in the health check is greater, the

health check was changed after you got the version number. Amazon Route 53 does not update the health check, and it returns a HealthCheckVersionMismatch error.
