Socket failures on HTTP SLA operation??

I just upgraded my VoIP Monitor to the new IP SLA module..

I'm setting up a few HTTP SLA operations as an initial test of the new features.. I've added 4 HTTP operations to one of my SLA endpoints, and one in particular shows down and also produces the following "status message" in the "Operation details" view:

Socket failures or other errors not relevant to the actual probe.

All 4 of these HTTP operations are against LOB web applications hosted in our European Home office. I can of course browse to all of these web server applications just fine..

Anybody run across this yet?? Any ideas??

Hi mmunford -

Can you verify that the IPSLA source node (the node running the IPSLA operation) can access the web servers hosting your applications?

Just because your browser can access the web sites doesn't necessarily mean the node actually running the IPSLA operation is able to reach the same web sites.

Hope this helps.

I have verified that I can telnet (from the SLA router) to port 80 on the target server with similar response as the other HTTP operations targets produce..

The error you're seeing is tied to an error response from the router itself.

Here is a link to Cisco's instructions for debugging the HTTP operation. You'll want to use the "debug" router commands to determine the cause of the router not being able to execute the HTTP operation. Is the device low on resources? (memory/CPU)?

Hope this helps.

The Router is definitely not low on CPU/memory resources.. avg of 10%CPU and 25% Mem Util..

cranking up some HTTP debugs now..

I have added a few more operations and a couple more produced the same error. One more HTTP operation and a DHCP operation...
