New Product of F5 Load Balancer

Dear Steve,

 

 

My Nodes members are up and after that when i created POOLS the pool members are showing down.

 

Please can you tell help me why it is showing down.

 

 

Thanks

The default node monitor is probably an ICMP monitor.

 

 

What monitor is configured for the Pool Members?

Dear Steve,

 

 

Please see attached document for your review of our current configuration.

 

Thanks

I'm confused. You are using Real_Server and SNMP monitors for the nodes but a HTTP monitor for the Pool Members. Exactly what type of service are you trying to load balance?

You are also using the same IP address for the VS as one of the Pool Members???

Dear Steve,

 

 

We have two application servers which are desktop applications and we have two web servers which will be deployed on IIS of two web servers.

 

 

REAL_SERVERS and SNMP monitors which were selected by default for two NODES from other monitor listed there NODES are not showing GREEN icon.

 

 

Only if we select REAL_SERVER for NODE 2 and SNMP for NODE1 these nodes show online.

 

 

Your Query:- You are also using the same IP address for the VS as one of the Pool Members

 

 

Our network Administrator gave us 10.21.X.X scheme of VLAN to play with.

 

 

So we give 10.21.100.1 for NODE1 and 10.21.100.2 for NODE2

 

 

And for Virtual Server we gave 10.21.200.1

 

 

And for self IP we gave 192.168.1.1

 

 

Please suggest.

 

 

Thanks

Only if we select REAL_SERVER for NODE 2 and SNMP for NODE1 these nodes show online. i think you should choose health monitor which matches application you are running. also, if you do not do dynamic ratio load balancing, i do not think you should use snmp_dca.

i guess pool member is marked down by http health monitor. Aaron has written excellent article about how to troubleshooting health monitor. hope it is helpful.

Malik, typically the ICMP health monitor is used for Node monitors. If the F5 can't even ping the servers successfully you've a real problem; perhaps firewall or HIDS/HIPS on the servers?

 

 

As Nitass has suggested, if you are running HTTP servers, you should be using a HTTP monitor to check their availability.

 

 

It may work but you should ideally be using a different IP address for your VS and Pool Members.

Dear Steve,

 

 

Once again thank you for your reply.

 

 

My Firewall is diable let me see the HIDS/HIPS status.

 

 

Thanks
