You can utilize ACE Device Manger which is a built-in GUI tool to monitor system statistics. It is bundled in any license.
It is pretty easy to start. You need only basic configurations to access management address via https, and
snmp community for monitoring.

# Monitoring a rserver

You can change time range to view the graph. Options are 1h, 2h, 4h, 8, 24h, or All Date.

On the ACE, statistics are kept for 7 days or  20,000 hourly records, whichever comes first.

# Monitoring L7 connection

I think grapsh for L7 connections are aggregate statistics of all L7 policies.

Row data view.You can download the data in Excel format.

You can find more detail about the Device Manager  in the Configuration Guide.

Some  sample shots of DM view are also on the configuration guide.

Thanks for your update. We didnot open the Http for SLB. could you give the CLI command for monitoring same output.

We use sh conn and sh conn details, sh rserver,sh serverform & sh service policy name detail.

I do not think there are cli commands that provide

number of connections connected to load balancer in avg and peak connection on  daily basis.

Cli commands usfull to know the number of connections per rservers and the hit count of a VIP are those you are already using.

There is a counter to tell you Peak connection number in "show resource usage" but it is context wide command, not specific to a VIP neither rserver.

Since https is not opened in your box, I think an option here is to use snmp so that you can steadily poll cesRserverCurrConns mib.

You can pick up the highest counter for peak also calculate avg.

Here is MIB list of ACE appliance.

Hope this helps.
