Steps to reproduce:

The Chassis by IPMI template, found at

https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/templates/server/chassis_ipmi/template_server_chassis_ipmi.yaml

is buggy.

It generates 6 triggers based upon IPMI threshold values, but it is using the wrong function in half (three) of  the trigger prototypes.

Specifcially the triggers named

• IPMI: {#SENSOR_ID} value is below critical low (less than {#SENSOR_LO_CRIT} for 5m)
• IPMI: {#SENSOR_ID} value is below non-critical low (less than {#SENSOR_LO_WARN} for 5m)
• IPMI: {#SENSOR_ID} value is below non-recoverable low (less than {#SENSOR_LO_DISAST} for 5m)

According to those names they should only be firing when the sensor has been beloow the critical range for the last 5 minutes, bbut because they are defined using the min() function, they will fire when ANY value in the 5 minutes exceeds that threshold.

The fix is to switch to using the max function in those trigger prototypes.

• {{ {min(5m)}<{#SENSOR_LO_CRIT}}}
  * {{{min(5m)}

  <{#SENSOR_LO_WARN}}}

• {{ {min(5m)}

  <{#SENSOR_LO_DISAST}}}

should become

• {{ {max(5m)}<{#SENSOR_LO_CRIT}}}
  * {{{max(5m)}

  <{#SENSOR_LO_WARN}}}

• {{ {max(5m)}

  <{#SENSOR_LO_DISAST}}}

This way it requires that ALL the values from the last 5 minutes are below those thresholds.
