<b>Subject:</b> [Kea-users] kea-2.2.0 - HA cluster - communication between stork and dhcp4 gets lost</font>

<div class="BodyFragment"><font size="2"><span style="font-size:11pt;">
<div class="PlainText">CAUTION: This email originated outside the organization. Do not click any links or attachments unless you have verified the sender.<br>
<br>
We see this in the stork events every few days:<br>
<br>
2023-06-20 20:01:23 daemon [2] dhcp4 is unreachable<br>
<br>
2023-06-20 20:01:07 Communication with daemon [2] dhcp4 of app<br>
kea@10.0.0.231 failed<br>
<br>
After a restart of both dhcp4 and stork-agent on that adc1-server things<br>
work again.<br>
<br>
I will have to check the logs in more detail, sure.<br>
<br>
2 things:<br>
<br>
1) we collect the prometheus metrics from stork and visualize them in<br>
Grafana.<br>
<br>
storkserver_auth_unreachable_machine_total{instance=~"$instance"}<br>
<br>
is always 0, even when the mentioned events are seen and I would assume<br>
that one of 2 machines should be marked unreachable. Right?<br>
<br>
2) it's not solving the problem at the root, but I consider setting up<br>
some external monitoring to detect this outage and let the monitoring<br>
restart the daemons ...<br>
<br>
I use monit (<a href="https://mmonit.com/wiki/Monit/ConfigurationExamples">https://mmonit.com/wiki/Monit/ConfigurationExamples</a>) for<br>
such things, and think of letting it do http-API-calls to isc-kea to<br>
check things.<br>
<br>
Right approach?<br>
<br>
thanks, Stefan<br>
