Methods

• classmethod External(type As %String = "SNMP", appname As %String = "", severity As %Integer = 0, msg As %String = "") as %Status
This class method allows a application to send an alert using an external monitoring or management interface, currently just SNMP. This call may be used within the Alert Evaluation Method to forward alerts generated by the Monitor, or from anywhere within the application itself to simply create an SNMP Trap.

The parameters used are:

type = use 'SNMP' to indicate how to send the alert

appname = a brief string (MAXLEN=20) to identify the source or application creating the alert

severity = a severity code where 0=info, 1=warning, 2=severe, 3=fatal

msg = a text message (MAXLEN=1024) which describes the problem or event

For SNMP, the alert is sent using the cacheAppAlert trap, with each of the parameters attached as auxiliary objects (see the ISC-CACHE.MIB).
