SIM with multiple isolated subnets

Neal Bowman — Fri, 24 Aug 2007 08:09:59 GMT

Hoping to get a sanity check before pulling the trigger on this setup, so feel free to post any suggestions!

We have a server lab contains a Some servers connected to our Production network, Development network, a Testing network, and a Sandbox network. Each of these four networks are isolated with no communication between any of the different environments. Each environment has it's own DNS, DHCP and Active Directory servers, and we are using the same server names in each environment to reduce having to modify so many different scripts.

We are wanting to set up a SIM server to monitor each of these servers in their respective environments. The SIM server will have a NIC connecting to each subnet.

Since we are using the same names throughout each environment, I am going to use a SIM host file to manually designate the SIM node. Below is an example host file I want to deploy (names, IP addresses, and SNMP strings are fake!)

======================================
# D=Dev
# T=Test
# S=Sandbox
# P=Production

#$IMXE: TYPE="Server" DMI=0 HTTP=1 SNMP=1
#$IMXE: SNMP_TIM=5 SNMP_RET=1 SNMP_MON=fakeXXX SNMP_CON=
3.9.1.10 D-SRV1.www.com D-SRV1

#$IMXE: TYPE="Server" DMI=0 HTTP=1 SNMP=1
#$IMXE: SNMP_TIM=5 SNMP_RET=1 SNMP_MON=fakeXXX SNMP_CON=
2.9.1.10 T-SRV1.www.com T-SRV1

#$IMXE: TYPE="Server" DMI=0 HTTP=1 SNMP=1
#$IMXE: SNMP_TIM=5 SNMP_RET=1 SNMP_MON=fakeXXX SNMP_CON=

#$IMXE: TYPE="Server" DMI=0 HTTP=1 SNMP=1
#$IMXE: SNMP_TIM=5 SNMP_RET=1 SNMP_MON=fakeXXX SNMP_CON=
4.9.1.10 P-SRV1.www.com P-SRV1

#$IMXE: TYPE="Server" DMI=0 HTTP=1 SNMP=1
#$IMXE: SNMP_TIM=5 SNMP_RET=1 SNMP_MON=fakeXXX SNMP_CON=
3.9.1.11 D-SRV2.www.com D-SRV2

#$IMXE: TYPE="Server" DMI=0 HTTP=1 SNMP=1
#$IMXE: SNMP_TIM=5 SNMP_RET=1 SNMP_MON=fakeXXX SNMP_CON=
2.9.1.11 T-SRV2.www.com T-SRV2

#$IMXE: TYPE="Server" DMI=0 HTTP=1 SNMP=1
#$IMXE: SNMP_TIM=5 SNMP_RET=1 SNMP_MON=fakeXXX SNMP_CON=
1.9.1.11 S-SRV2.www.com S-SRV2

#$IMXE: TYPE="Server" DMI=0 HTTP=1 SNMP=1
#$IMXE: SNMP_TIM=5 SNMP_RET=1 SNMP_MON=fakeXXX SNMP_CON=
4.9.1.11 P-SRV2.www.com P-SRV2

======================================

Is this a doable scenario for using SIM, without having to setup 3 separate SIM servers?

Thoughts? Thanks in advance for any input on this.

HP SIM is going to bind to a single address, so you're going to need to enable some fancy routing to enable it to see each of these.

No it's easy if SIM can ping it, it will discover it. You many need a backside NIC so SIM can ping it.

David,

So even if I have static IP addresses assigned to the NICs (NIC1 = 3.9.1.1, NIC2 = 2.9.1.1, NIC3 = 1.9.1.1, and NIC4 = 4.9.1.1) the server will only see devices it can see via primary NIC (4.9.1.1)?
