Gajji,

 

I don't believe the curl script will use cookie persistence so the requests should be round robined across the pool members.

 

Anyway, my advice is to configure a HTTP monitor as the port may be up, but the service may be at fault. A HTTP monitor would highlight this and you may see monitor fail messages on the LTM too. This would then point to a backend server issue, or something else that you can use for root cause analysis.

 

Hope this helps,

N
