<div id="body1547193420658"><div class="section" id="ALM-12073__section24601758201512"><h4 class="sectiontitle">Description</h4><p id="ALM-12073__p99041958181518">HA checks the cep resources of Manager every 60 seconds. This alarm is generated when HA detects that the cep resources are abnormal for 2 consecutive times.</p>
<p id="ALM-12073__p69041558161518">This alarm is cleared when the CEP resource is normal.</p>
<p id="ALM-12073__p1490411584158"><strong id="ALM-12073__b79043583158">Resource Type</strong> of CEP is <strong id="ALM-12073__b1904175821515">Single-active</strong>. Active/standby will be triggered upon resource exceptions. When this alarm is generated, the active/standby switchover is complete and new CEP resources have been enabled on the new active FusionInsight Manager. In this case, this alarm is cleared. This alarm is used to notify users of the cause of the active/standby switchover.</p>
