US 2018/0006871 A1 · SERVING CHANNELIZED INTERACTIVE DATA COLLECTION REQUESTS FROM CACHE

Abstract

Expressions to calculate values from data collection can often involve additional data collection queries causing duplicate requests for SNMP data collection. The duplicate requests can lead to increased latency or even data loss as SNMP data collection requests are throttled in a network. To eliminate duplicate requests, data collection channels for variable SNMP data collection can be managed with a queue for duplicate requests. Channels for which a data collection request has already been submitted can be locked while the request is pending. Additional requests for the locked channel are considered duplicate requests and are queued until a value is returned for the initial request. The returned value is then supplied to each of the queued requests, and the channel is unlocked.

Dependent claims

A method comprising:

after receipt of a first request for a simple network management protocol (SNMP) data collection,
identifying a first data collection channel indicated in the first request, wherein the first data collection channel is indicated by a device address and an object identifier;
locking the first data collection channel;
and
submitting the first request for SNMP data collection;
after receipt of a second request for an SNMP data collection,
determining that the second request indicates the first data collection channel;
and
based on determining that the first data collection channel is locked, blocking the second request;
and
adding the second request to a queue;
upon receipt of a value in response to submitting the first request for SNMP data collection,
supplying the value in response to the first request;
and
based on determining that the second request is in the queue, supplying the value in response to the second request.

An apparatus comprising:

a processor;
and
a machine-readable medium having program code executable by the processor to cause the apparatus to,
after receipt of a first request for a simple network management protocol (SNMP) data collection,
identify a first data collection channel indicated in the first request, wherein the first data collection channel is indicated by a device address and an object identifier;
lock the first data collection channel;
and
submit the first request for SNMP data collection;
after receipt of a second request for an SNMP data collection,
determine that the second request indicates the first data collection channel;
and
based on a determination that the first data collection channel is locked,
block the second request;
and
add the second request to a queue;
upon receipt of a value in response to submitting the first request for SNMP data collection,
supply the value in response to the first request;
and
based on a determination that the second request is in the queue, supply the value in response to the second request.
