Steps to reproduce:

Use any of "Template Module Interfaces SNMPv2" against a snmp router/switch with network interface which generate errors once. Look at the trigger "Interface {#IFNAME}({#IFALIAS}): High error rate"

Result:
Trigger sets
Trigger never recovers
Expected:
Trigger sets
Trigger recovers after value have been constant over x minutes

 

Current problem expression:

avg(/Template Module Interfaces SNMPv2/net.if.in.errorsifInErrors.{#SNMPINDEX},5m)>{$IF_ERRORS_WARN:"

{#IFNAME}"}
or avg(/Template Module Interfaces SNMPv2/net.if.out.errorsifOutErrors.{#SNMPINDEX},5m)>{$IF_ERRORS_WARN:"{#IFNAME}

"}

 

Current revoery expression:

avg(/Template Module Interfaces SNMPv2/net.if.in.errorsifInErrors.{#SNMPINDEX},5m)<={$IF_ERRORS_WARN:"

{#IFNAME}"}*0.8
and avg(/Template Module Interfaces SNMPv2/net.if.out.errorsifOutErrors.{#SNMPINDEX},5m)<={$IF_ERRORS_WARN:"{#IFNAME}

"}*0.8
