Check that the Clock of a switch match's NTP source?

Spiky

basically, what would be nice is to have an alert to tell me when switch's dont match the NTP server

 we are using some routers as servers, which then update via the internet to a NTP server.

Hi Spiky,

You should try to create a Universal Device Poller on the following OID:

http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=cntpSysSrvStatus

Object	cntpSysSrvStatus
OID	1.3.6.1.4.1.9.9.168.1.1.11
Type	INTEGER
Permission	read-only
Status	current
Values	1 : unknown 2 : notRunning 3 : notSynchronized 4 : syncToLocal 5 : syncToRefclock 6 : syncToRemoteServer
MIB	CISCO-NTP-MIB ;   -   View Supporting Images javascript:openChildWindow('/ITDIT/MIBS/AdvancedSearch?MibSel=4631','MIBLocator');
Description	"Current state of the NTP server with values coded as follows: 1: server status is unknown 2: server is not running 3: server is not synchronized to any time source 4: server is synchronized to its own local clock 5: server is synchronized to a local hardware refclock (e.g. GPS) 6: server is synchronized to a remote NTP server"

This will return you the status of the clock on your switch. Then you can create an advanced alert which will trigger an action based on the value of that UnDP.

If that OID does not return anything you should browse the Cisco-NTP-MIB for another OID which might more relevant or verify that this MIB is supported on your switch.

To Create the UnDP => Create a Universal Device Poller (UnDP) in the Orion Platform - SolarWinds Worldwide, LLC. Help and Support

To Create the advanced alert, ensure you have the "Type Of Property to monitor" set to Custom Node Poller in the Trigger Condition tab, otherwise you will not have the option to select the UnDP status in the conditions.

Cheers
