Temporarily Disable SNMP Traps

When doing releases, it is not unusual for an application server to be taken down but when this occurs, a health check failure will often occur. Or, if a host is decommissioned before it is removed from the load balancer. Is there a way to temporarily suspend or suppress a health check per node and/or per pool member or to temporarily suppress SNMP traps getting issued for a host or pool member?

  • Hello Mahnsc.

    You can stop the service during those maintenance works.

    ## Stop services
    tmsh stop sys service snmpd
    tmsh stop sys service alertd
     
    ## Check services status
    tmsh show sys service snmpd
    tmsh show sys service alertd
     
    ## Start services
    tmsh stop sys service snmpd
    tmsh stop sys service alertd

    Regards,

    Dario.

      BTW, in section SNMP > Traps > Configuration > Agent Start / Stop

      You can disable SNMP Traps exclusively.

        Thanks! I apologize for not responding sooner. I was hoping to see if there was a solution that could be applied more granularly to specific nodes and/or pools but it doesn't appear so.
