针对警报操作使用工作流

可选择性地将工作流作为警报执行。要使工作流符合作为警报操作的资格，其 alert 操作必须设置为 true。

当作为警报操作执行时，工作流以创建工作流的用户身份运行。出于此原因，任何有资格作为警报操作的工作流必须将 setid 设置为 true。警报操作具有一个对象参数，该参数具有以下成员：

parameters 对象的 items 成员具有以下成员：

作为警报操作执行的工作流可以使用 audit 函数生成审计日志条目。建议通过 audit 函数将所有相关的调试信息生成到审计日志中。例如，下面是如果处于群集状态则执行故障转移的工作流－但是它审计所有无法重新引导故障：

例如，下面是如果处于群集状态则执行故障转移的工作流－但是它审计所有无法重新引导故障：

var workflow = {
       name: 'Failover',
       description: 'Fail the node over to its clustered peer',
       alert: true,
       setid: true,
       execute: function (params) {
               /*
                * To failover, we first confirm that clustering is configured
                * and that we are in the clustered state.  We then reboot,
                * which will force our peer to takeover.  Note that we're
                * being very conservative by only rebooting if in the
                * AKCS_CLUSTERED state:  there are other states in which it
                * may well be valid to failback (e.g., we are in AKCS_OWNER,
                * and our peer is AKCS_STRIPPED), but those states may also
                * indicate aberrent operation, and we therefore refuse to
                * failback.  (Even in an active/passive clustered config, a
                * FAILBACK should always be performed to transition the
                * cluster peers from OWNER/STRIPPED to CLUSTERED/CLUSTERED.)
