http-comp rate Denied

Unanswered Question


I have an ACE4710 with a 100Mbps compression license. I have configured compression which seems to be working, but I have noticed, using sh resource usage all, that we have a high number of denied http-comp rate denied. What I would like to know is if this number is peak in time or accumulated over time.

Our resource usage is

/* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin;}         Resource         Current       Peak        Min        Max       Denied
  http-comp rate                0   13107200          0   13107200   81982748

so looking at these stats, it would imply a 725Mbps if it is point in time, or do i have to workout based on the duration?

Thanks for your help

I have this problem too.

Hello Ian,

The denied number is cumulative, not a peak.  It will just keep going up as you continue to peak at the maximum value.

Hope this helps,

Actually I not aware of any tips on calculating it.  However, I would think that if you are running at peak, and monitor how many bytes of denies go up over a period of time, then you could calculate the bytes per second that are being denied.  The numbers you see are in bytes so you would need to multiply by 8 to get bits per second.

Current Max:  13107200

Current Max Throughput:  13107200 * 8 = 104857600 = 100 Mbps

Correct.  When the comp throughput drops below the max, then the denies will not go up.  I would think that you could still use a time period for measuring.  If it is generally on the edge of peak, then I would think that going from 100 Mbps to 500 Mbps should do it.

I'm not aware of any easier way.
