I usually refer to the timezone conversion table at Eastern Time to GMT

For example let say the online seminar is happening at EDT 21:00, it will be 01:00, +8 which is 09:00 (the next day) in my country.

Here is the instruction of how to access to list of Preapproved Payment in your Paypal.

• After login to Paypal, on top of the menu, click on “Profile”.

It actually took me quite sometime to figure how to access preapproved payments list

check_dns usage is as below

$ ./check_dns -H host [-s server] [-a expected-address] [-A] [-t timeout] [-w warn] [-c crit]

Try to run the command as below and you will get the query result

$ ./check_dns -H systems.takizo.com -s 8.8.8.8
DNS OK: 0.012 seconds response time. systems.takizo.com returns 70.32.103.130|time=0.011703s;;;0.000000

Sweet, that is the DNS query plugin, it does DNS query check on your DNS host server and return the query time.
Here is how to activate the monitoring, add the check_dns plug-in into Nagios’ commands.cfg configuration file.

On FreeBSD server, it’s located at /usr/local/etc/nagios/objects/commands.cfg
Edit the file commands.cfg and add the line below

define command {
        command_name    check_dns
        command_line       $USER1$/check_dns -H $ARG1$ -s $HOSTADDRESS$
}

• $ARG1$ is the argument you will parse into in the configuration
• $HOSTADDRESS$ is your host on Nagios monitoring.

Next, put the line below into service check configuration file

define service {
        use                                  generic-service
        host_name                       your-dns-host
        service_description          Check Google.com on DNS Server
        check_command              check_dns!www.google.com
}

Restart your Nagios service now

$ /usr/local/etc/rc.d/nagios restart

If it’s failed, you will the red color on the monitoring status. There are a lot other plug-ins can be explore too. Have fun.

Here is how you can extend your Mac OSX display to external monitor only. Well, don’t forget you need an external keyboard to make yourself comfort at sitting posture

• on System Preference > Displays, choose mirror display
• Put your laptop into sleep by closing the lid
• Clicking and clicking on your keyboard/mouse to wake up your OSX, when it’s awake, your external monitor will become the only display
• In order to wake your display on your Macbook, just press the keyboard on your Macbook

Unfortunately, I can’t find any tools/apps can switch the display to external monitor. If you found one, do let me know.

While doing verbose logging on spine, we saw the message “Spine Timed Out While Processing Hosts Internal” freezing until it reaches the script time out at 40 seconds. The logs didn’t provide much info and the actual fixes are available at Cacti Official Spine Patches website. After apply the patches, Spine 0.8.7g is working on the FreeBSD’s box. Most of our packages installation are through FreeBSD ports, I guess that we have to check on Cacti’s Official website to look for patches. Or the maintainer should grab the latest patches and update from FreeBSD ports

If Spine installation is from FreeBSD ports. Here is the step by step to fixed Spine 0.8.7g problem.

• Go to /usr/ports/net-mgmt/cacti-spine/
• Perform make clean to wipe off previous compiled files
• Do make extract to extract the source files
• On current directory, go to work/cacti-spine-0.8.7g/
• Download the latest patch from Cacti’s website and apply the patches
• Make to build the app from patches
• Make deinstall to uninstall current cacti
• and finally make install to install patched spine into binary folder.

shell> cd /usr/ports/net-mgmt/cacti-spine/
shell> make clean
shell> make extract
shell> cd work/cacti-spine-0.8.7g/
shell> wget http://www.cacti.net/downloads/spine/patches/0.8.7g/unified_issues.patch
shell> patch -p1 -N < unified_issues.patch
shell> make
shell> make deinstall
shell> make install

There are a few steps involve In order to install Cacti Plugin Architecture. First we will need to backup current cacti files, and overwrite the files for Cacti Plugin Architecture and lastly to make some changes on configuration files in order to activate Cacti Plugin Architecture.

Installing Cacti Plugin Architecture

Cacti Plugin Architecture can be downloaded at Cacti Users website. The demo I am going to show is to download Cacti Plugin Architecture version 2.8 on Cacti version 0.8.7g.

Before installing Cacti Plugin Architecture, lets make a backup copy of your cacti files, in case something goes wrong, you can roll back to the original files. During the backup, we are going to exclude rra and log directory.

First change directory to the directory which located Cacti files, in FreeBSD would be /usr/local/share

shell> cd /usr/local/share
shell> tar -zcf cacti.backup.tar.gz --exclude=rra --exclude=log cacti

After backup, it’s now safe to replace your cacti files with cacti architecture files. First untar Cacti Plugin Architecture which you have downloaded earlier.

shell> tar -zxf cacti-plugin-0.8.7g-PA-v2.8.tar.gz

After untar-ed cd to plugin architecture folder and edit config.php.dist file with your mysql database credentials. Follow with rename the file to config.php

shell> tar -zxf cacti-plugin-0.8.7g-PA-v2.8.tar.gz
shell> cd cacti-plugin-arch
shell> vi include/config.php.dist
shell> mv include/config.php.dist include/config.php

In include/global.php, edit MySQL database credentials as well.

shell> vi include/global.php

Next, create the database table which required by Plugin Architecture. The file is located at cacti-plugin-arch directory with file name pa.sql.

shell> mysql -u username -p cacti < pa.sql

Now, it's all good, copy all the files into cacti directory. You cacti directory might be different from mine directory path.

shell> cp -rf * /usr/local/share/cacti/

The installation for Cacti Plugin Architecture is done. In order to access to Plugin Setting. Log on to Cacti, go to User Management, click on Admin, check Plugin Management on realm management and Save.

You should see Plugin Management on your left menu bar. On the next post we will go through the plugins for Cacti Plugin Architecture.
