Poller Type - Performance Impact

ckendrick

In adding devices via the SDK - I am curious if there are performance repercussions when adding unnecessary pollers to a node.

In the example below, if the poll method was ICMP - would adding all six pollers impact the performance of SolarWinds?

Here is the only information I could find on these pollers. Additional resources / information would be appreciated!

Poller Types · solarwinds/OrionSDK Wiki · GitHub

# Status
	$poller["PollerType"]="N.Status.ICMP.Native";
	$pollerUri = New-SwisObject $swis -EntityType "Orion.Pollers" -Properties $poller
	# Response time
	$poller["PollerType"]="N.ResponseTime.ICMP.Native";
	$pollerUri = New-SwisObject $swis -EntityType "Orion.Pollers" -Properties $poller
	# Details
	$poller["PollerType"]="N.Details.SNMP.Generic";
	$pollerUri = New-SwisObject $swis -EntityType "Orion.Pollers" -Properties $poller
	# Uptime
	$poller["PollerType"]="N.Uptime.SNMP.Generic";
	$pollerUri = New-SwisObject $swis -EntityType "Orion.Pollers" -Properties $poller
	# CPU
	$poller["PollerType"]="N.Cpu.SNMP.CiscoGen3";
	$pollerUri = New-SwisObject $swis -EntityType "Orion.Pollers" -Properties $poller
	# Memory
	$poller["PollerType"]="N.Memory.SNMP.CiscoGen3";
	$pollerUri = New-SwisObject $swis -EntityType "Orion.Pollers" -Properties $poller

An ICMP node does not have SNMP credentials assigned, so those other pollers won't work. You might see some errors in the logs.

I generally recommend using the Discovery API (Discovery · solarwinds/OrionSDK Wiki · GitHub) to let the system figure out which pollers apply for a given node.
