explanation of virtual server stats

Hi,

 

 

Im trying to look at throughput from b virtual stats show. I want to know,

 

 

a) what is the maximum throughput rate that has reached this virtual server in mb/s

 

b) what the highest has been.

 

 

Also how do I see the throughput or bandwidth that has been sent to all virtual servers? or combined?

 

 

I am trying to understand the output below, could someone help me or explain where this is documented as i cant find it in any of the config/system admin guides and b virtual stats help gives me an error,

 

 

VIRTUAL Virtual-HTTP - stats:

 

| (cur, max, limit, tot) = (79544, 202507, 0, 3.212G)

 

| (pkts,bits) in = (118.3G, 188.4T), out = (98.64G, 889.2T)

 

 

 

Thx

  • Hi,

     

     

    The (cur, max, limit, tot) = (79544, 202507, 0, 3.212G) means that there's currently 79544 connections, a maximum of 202507 connections at any one time since the box was booted, and a cumulative total of 3.2 billion (?) connections since the box was booted. Packets and bits totals are also cumulative. I can't see a good way to calculate max throughput with just that data.

     

     

    The Performance graphs in the GUI can show the max throughput up through the last 30 days.

     

     

    The Enterprise Manager 1.7 (on EM3000 hardware) has statistics-gathering capability that can show historical data and trending more like you are looking for.

     

     

    There's also a lot of good posts here on DC about using Cacti to graph LTM data. Click here

     

     

    Hope that helps,

  • For stats on interface throughput, here's a little perl script (requires Net::SNMP):
