PPS: Not sure if works everywhere... '''write mib-data''' might be needed as well | |||
=== SNMP Instance Discovery === | |||
Let's say we want to collect status of all interfaces on a node. | |||
Put OID of interest in "Parameter" field on "General" tab with {instance} suffix (.1.3.6.1.2.1.2.2.1.8.{instance}). | |||
Put something meaningful in "Description" filed on "General" tab, use {instance-name} macro to make this human-readable ("Interface status ({instance-name})"). | |||
Go to "Instance Discovery" tab. | |||
Pick "SNMP Walk - Values" as discovery method. | |||
Pick proper base OID as described in [[Creating SNMP table DCI]] (.1.3.6.1.2.1.2.2.1.1). | |||
Add instance discovery filter script: | |||
snmp = CreateSNMPTransport($node); | |||
ifName = SNMPGetValue(snmp,".1.3.6.1.2.1.2.2.1.2." . $1); | |||
ifType = SNMPGetValue(snmp,".1.3.6.1.2.1.2.2.1.3." . $1); | |||
return %((ifType==6), $1, ifName); | |||
{instance-name} in "Description" filed will be replaced with 3rd parameter returned from the filter script (ifName in that case). | |||

Note, that different set of macros available for Activation and De-activation of alarms. For example, if you use unique DCI ID for alarm generation ('''%5'''), you should use different macro to de-activate this alarm ('''%3''') | Note, that different set of macros available for Activation and De-activation of alarms.

==== Referring scripts from Script Library ==== | |||
Calling scripts from Script Library: | |||
myVariable=Name::In::Script::Library/functionName | |||
==== Event Processing Policy ==== | |||
Calling Script Library scripts from Action in Event Processing Policy: | |||
%[Name::In::Script::Library/functionName] | |||
NB: you can not pass any parameters when calling scripts from EPP Actions, however you have access to $event and $node object | |||
