Disabling statistical interface polling

There is a memory leak bug in the IOS we have deployed on our Nexus 5xxx switches that causes them to crash and reboot. These are our core switches, so that is bad!

The Network team has asked for SolarWinds to stop collecting interface statistical data, BPS, drops, errors, etc.

In QA I have tried to set the pollers to enabled = 0:

update pollers Set Enabled = 0 Where NetObjectID in (Select i.InterfaceID from Interfaces i join NodesData n on n.NodeID = i.NodeIDwhere n.Caption = 'SwitchName.noc')AND PollerType like '%Statistics%'

Checking the poller status:

select pollers.*  from pollers join interfaces i on i.InterfaceID = pollers.NetObjectIDWhere NetObjectID in (Select i.InterfaceID from Interfaces i join NodesData n on n.NodeID = i.NodeIDwhere n.Caption = 'SwitchName.noc')

returns this:

PollerID    PollerType    NetObject    NetObjectType    NetObjectID    Enabled7689    I.StatisticsErrors32.SNMP.IfTable    I:559    I    559    07690    I.StatisticsTraffic.SNMP.Universal    I:559    I    559    07691    I.Status.SNMP.IfTable    I:559    I    559    07692    I.Rediscovery.SNMP.IfTable    I:559    I    559    07693    I.StatisticsErrors32.SNMP.IfTable    I:560    I    560    07694    I.StatisticsTraffic.SNMP.Universal    I:560    I    560    07695    I.Status.SNMP.IfTable    I:560    I    560    07696    I.Rediscovery.SNMP.IfTable    I:560    I    560    07697    I.StatisticsErrors32.SNMP.IfTable    I:561    I    561    07698    I.StatisticsTraffic.SNMP.Universal    I:561    I    561    07699    I.Status.SNMP.IfTable    I:561    I    561    07700    I.Rediscovery.SNMP.IfTable    I:561    I    561    07701    I.StatisticsErrors32.SNMP.IfTable    I:562    I    562    07702    I.StatisticsTraffic.SNMP.Universal    I:562    I    562    07703    I.Status.SNMP.IfTable    I:562    I    562    07704    I.Rediscovery.SNMP.IfTable    I:562    I    562    07705    I.StatisticsTraffic.SNMP.Universal    I:563    I    563    07706    I.Status.SNMP.IfTable    I:563    I    563    07707    I.Rediscovery.SNMP.IfTable    I:563    I    563    07708    I.StatisticsErrors32.SNMP.IfTable    I:564    I    564    07709    I.StatisticsTraffic.SNMP.Universal    I:564    I    564    07710    I.Status.SNMP.IfTable    I:564    I    564    07711    I.Rediscovery.SNMP.IfTable    I:564    I    564    07712    I.StatisticsErrors32.SNMP.IfTable    I:565    I    565    07713    I.StatisticsTraffic.SNMP.Universal    I:565    I    565    07714    I.Status.SNMP.IfTable    I:565    I    565    07715    I.Rediscovery.SNMP.IfTable    I:565    I    565    0

All pollers are not enabled but the thing just keeps collecting statistical and UP/DOWN status.

What am I missing?

Any help appreciated...

You will want to go into Settings> Manage Nodes, then select the Node and select List Resources. In the List Resources screen you can select No Interfaces statistics, it will remove Interface Availability (Operation and Administrative status), Interface Traffic (bps, percent utilization) and Interface Errors (Errors and Discards).

Making direct changes to the Pollers table can cause polling issues in the future, which in the end may require deleting and re-adding the device if done improperly.

Have you considered un-managing the Nexus? It's kind of like killing a fly with a bazooka, but it will stop the polling.

OK now I have gone Big Stick and set enabled to 0 for all pollers on the node and the interfaces.
No change. The router and it's interfaces just keep on polling...

mlandman

They, Network Opps, want UP/Down alerting on the interfaces since all the secure zone firewalls and other things hang off of these switches. If I make the router and ICMP polled device, all the interfaces go Bye Bye, not desired.

ken_cohen

You still need to poll the router to get the interface status, but you don't want to poll for the stats. I'll see if I can do that with one of my devices.
