great, however there does not seam to be any great way to acknowledge the<br>

<p class="MsoNormal"><br>
it's possible to resolve event in mmhealth:<br>
<br>
# mmhealth event resolve<br>
Missing arguments.<br>
Usage:<br>
mmhealth event resolve {EventName} [Identifier]<br>
<br>
-> `mmhealth event resolve cluster_connections_down AFFECTED_IP` should do the trick.<br>
<br>
In our clusters, a regular reboot doesn't seem to trigger this event. All our nodes are running Scale >= 5.2.0<o:p></o:p></p>

<p class="MsoNormal">Our clusters (5.1.9-3 on the client side, and either 5.1.5-1 or 5.1.9-2 on the storage side) also show downed connections, but I wish this were somehow tunable. A single downed client that’s not even part of the same cluster is not a reason
to alert us on our storage cluster. We monitor MMHEALTH via Nagios, and so we’re occasionally getting messages about a single client.<o:p></o:p></p>
