Hardware Requirements
The hardware requirements for monitoring and target hosts are different. The monitoring monitoring host should be a machine dedicated to the IEPM-BW software. The host must have enough cpu 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
...
Following are the software requirements for the IEPM-BW monitoring node.
- Recommended operating system is the latest stable version of RedHat or any flavour of Fedora, more suitably Fedora Core 5.
- Two accounts should be created on the monitoring machine as these are needed to install and run IEPM-BW.
...
- 'iepm' is a user account and is used for running IEPM-BW
...
- .
- Account = iepm, home directory = /home/iepm
- .
...
- Second account is an account with root privileges
...
It is recommended that the operating system be the latest stable version of RedHat.
...
- . This is account is used for installation and administration. It's 'cyrus' in my case.
- Account = cyrus, home directory = /home/cyrus
You can have your own account, but don't forget to replace it at every place with your own account.
- Account = cyrus, home directory = /home/cyrus
- . This is account is used for installation and administration. It's 'cyrus' in my case.
- An apache web server has to be available, and the recommended document root is '/var/www'.
- Standard MySQL must be installed on the system.
...
- Most recommended is the latest stable release, as this will facilitate assuring the upward compatibility of the code.
...
- Make sure that the system is configured to
...
- autostart MySQL and httpd (apache web server) upon booting.
...
- On some systems this can be
...
- done with 'chkconfig'.
...
- Commands are
| Code Block |
|---|
chkconfig httpd on
chkconfig mysqld on
|
- The following /etc/sysctl.conf parameters are recommended for optimum performance
...
| Code Block |
|---|
/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 |
The following ports must be open for the probes
Test Name | Port# |
|---|---|
iperf | 5000 |
owamp(2.0)link | 4824 |
thrulay | 5003 |
pathchirp | 8365 udp |
pathload | 55001 udp |
pathload | 55002 tcp |
Keep in mind to open port for each and every other service you run. e.g. HTTP, NTP etc
- To allow for
...
- running OWAMP, the monitoring and target hosts should be configured with 4 NTP servers. The OWAMP documentation discusses how to setup NTP
...
- .
...
- The
...
- latest version of JAVA must be installed on the monitoring host.
- Gnuplot 4.0 is required and must be installed on the monitoring host machine
...
Important notes for later reference:
- To start the mysql daemon, use mysqld_safe&
- To set the root password after installation use: mysqladmin -u root password "new password"
- To shut mysql down, use mysqladmin -u root -p shutdown
...
- Perl should be installed locally on the machine. It can be either in
...
-
/usr/bin/perlor/usr/local/bin/perl. There should be a link
...
- from where it doesn't exist to where it exists. Suppose if Perl path is
/usr/bin/perl, its link should be created at/usr/loca/bin/perl. Perl modules must be installed on the system.
