Hardware Requirements
The hardware requirements for monitoring and target hosts are different. The monitoring should be a machine dedicated to the IEPM-BW software. The host must have enough cpu power to run the probes, drive the MySQL database, and run the analysis. It should also have enough disk space to support the database. The recommended monitoring host hardware configuration is:
...
- A gigabyte of memory is recommended
- If the machine is dedicated to being a target, 1 Gz of CPU is enough.
- Very little disk space is required. The server code is small and can reside in the home directory of the account it runs from.
Software Requirements
A minimum of two accounts are needed to install and run IEPM-BW. The account for running IEPM-BW should be named 'iepm', and the recommended home directory is '/home/iepm'. An account with root privileges for the installer/administrator is also required.
It is recommended that the operating system be the latest stable version of RedHat.
The following /etc/sysctl.conf parameters are recommended for optimum performance on both the Monitoring host and the target host: /proc/sys/net/core/wmem_max = 20971520
/proc/sys/net/core/rmem_max = 20971520
/proc/sys/net/core/rmem_default = 65536
/proc/sys/net/core/wmem_default = 65536
/proc/sys/net/ipv4/tcp_rmem = 4096 87380 20971520
/proc/sys/net/ipv4/tcp_wmem = 4096 65536 20971520
