snmpTable (Source)

When To Use

Use snmpTable for indexed SNMP data. It is usually more efficient than issuing many snmpGet calls.

Syntax

sources:
  batteryInfo:
    type: snmpTable
    oid: 1.3.6.1.2.1.33.1.2.3
    selectColumns: ID,1,2,3,4

Properties

Property Required Default Description
type Yes None snmpTable.
oid Yes None Base table OID to walk.
selectColumns Yes None Columns/indexes to keep (ID commonly preserves table index).
executeForEachEntryOf No None Fan-out execution context.
computes No [] Post-processing pipeline.
forceSerialization No false Serialize execution via a per-connector, per-host lock (see the Sources overview). Default false.
  • Start with one snmpTable and shape downstream with computes.
  • Preserve stable join keys (ID or explicit index columns).
  • Use tableJoin to enrich with complementary tables.

Common Mistakes

  • Dropping index columns too early.
  • Joining on translated labels instead of stable IDs.
  • Overusing scalar snmpGet where one table walk is enough.
