snmp-walk

Protocol: snmp.walk

snmp.walk reads a whole branch at once and returns array(suffix => value): here, hrSWRunName, one entry per program running on the device, counted.

How to read it

• The suffix is what follows the OID asked: for hrSWRunName, the index of each program.
• An empty branch is an answer, an empty array, not a failure: a device without the branch returns 0 programs. To tell "nothing" from "not served", read one OID first with snmp.get.
• list.count counts the elements of an array.

To adapt it

• foreach ($names as $index => $name) goes over the branch, the suffix and the value (see examples/watches/deviate).
• Several columns of the same table, lined up by index: snmp.table (see examples/protocols/snmp-table).
