Unable to Discover Load Balancer in Map.

Hi Team,

I able to Classify the Load Balancer IP using Horizontal Discovery(Quick Discovery). But in buiness service i am getting error that

"all commands failed on host: xx.yy.zz.aa. context: null/null

all commands failed on host:

xx.yy.zz.aa. command type: SNMP_SCALAR. command track: SnmpScalarCommand\(Relevant),; input: *.*.*.1.4.1.3375.2.*.4.1

Please suggest me what could be the reason.

Thanks,

Nimmi

Hi Nimmi,

OOB ServiceNow does not have the capability to discovery load balancer by SSH. So you should discover only with SNMP.

You need to provide the list of OID's which we send it from ServiceNow to discover load balancer pools and services. If you are using F5 load balancer then you provide SNMP - F5 BIG-IP - System probe's SNMP field values to your network team. You can tell your network team that these commands only get the information from F5 and do not harm the load balancer.

Regards,

Vivek

Hi Vivek,

I have one doubt. Can we update SNMP's OID in our instance with Device OID.

If you look into my 1st description of the issue. "xx.yy.zz.aa. command type: SNMP_SCALAR. command track: SnmpScalarCommand\(Relevant),; input: *.*.*.1.4.1.3375.2.*.4.1".

I can't see this OID (*.*.*.1.4.1.3375.2.*.4.1) in our SNMP's OID list. Is it of device?

If yes then can we update SNMP's OID in our instance with Device OID?

Please suggest.

TIA,

Nimmi

I don't think that *.*.*.1.4.1.3375.2.*.4.1 is a valid system ID. You can find the valid system OID in Discovery SNMP - Classify probe's ECC queue logs. If you find the system OID something like 1.3.6.1.4.1.3375.2.1.3.4.1 and if that is missing in System OID table then you can add.

Thank you Vivek. Do you have a resource to point to or information of what commands are being run on the F5? Our network team wants this information before we can discover it.

Hi Casey,

You can always get that information from Probes. You can look for F5 probes and give the SNMP field information to your network team.
