Hi,
sorry for the delay.
your answer is correct. I configured a multilevel alarm and it works.
I paste here my multi-level-alert-rules.xml file:
<rules>
<rule tag="CPU_RAM Alert" alert="HostSystem" attributeKey="cpu|usage_average" criticality="critical">
<cond operator="and">
<cond type="ht" operator="<=" cancelCycles="12" waitCycles="2880">
<token resourceKind="HostSystem" attributeKey="cpu|usage_average" />
<value>40</value>
</cond>
<cond type="ht" operator="<" cancelCycles="12" waitCycles="2880">
<token resourceKind="HostSystem" attributeKey="mem|usage_average" />
<value>40</value>
</cond>
</cond>
</rule>
</rules>
I hope it will be useful for other vCops users.
Thanks a lot
IG
