RedHat How to troubleshoot a 1000 nodes Apache cluster?

Hi all.

May I get some expert advice on troubleshooting performance issues of a 1000 nodes Apache LB cluster. Users report slow loading/response of webpages. Different websites are hosted on this cluster for different clients. But all are reporting the same issue.

Could you please let me know what all basic aspects you would take into consideration for this sort of issue.

FYI. I do not have access to the load-balancers.

clsetup(1CL)						 Sun Cluster Maintenance Commands					      clsetup(1CL)

NAME
clsetup - configure Sun Cluster interactively SYNOPSIS
/usr/cluster/bin/clsetup -V /usr/cluster/bin/clsetup -? /usr/cluster/bin/clsetup [-f logfile] DESCRIPTION
The clsetup command provides the following configuration capabilities, depending on what state the cluster is in when you issue the com- mand. The user must be superuser to run this command. This command has no short form. o When you run the clsetup command at post-installation time, the command performs initial setup tasks, such as configuring quorum devices and resetting the installmode property. If you deselected automatic Quroum Configuration when you created the cluster using either scinstall or the cluster create command, then you must run the clsetup command immediately after the cluster has been installed. Ensure that all nodes have joined the cluster before you run the clsetup command and reset the installmode prop- erty. If you used automatic quorum configuration when you created the cluster, you do not need to run the clsetup command after clus- ter installation. The automatic quorum configuration feature also resets the installmode property of the cluster. You can issue this form of the clsetup command from any node in the cluster. o When you run the clsetup command during normal cluster operation, the scsetup command provides an interactive, menu-driven util- ity to perform cluster configuration tasks. The following are some of the cluster components which this utility administers: o Quorum o Resource groups o Data services o Cluster interconnect o Device groups and volumes o Private hostnames o New nodes o Other cluster properties You can issue this form of the clsetup command from any node in the cluster. o When you run the clsetup command from a node that is in noncluster mode, the clsetup command provides a menu-driven utility for changing and displaying the private IP address range. You must reboot all nodes into noncluster mode before you start this form of the clsetup utility. OPTIONS
The following options are supported: -? --help Prints help information for the command. -f logfile --file logfile Specifies the name of a log file to which commands can be logged. If this option is specified, most command sets generated by clsetup can br run and logged, or just logged, depending on user responses. -V --version Prints the version of the command set. No command line processing will be performed and the command will not enter into its interactive menu. ATTRIBUTES
