Highcharts Phantomjs Export - TypeError: 'undefined' is not an object

Generating a png file from config-

phantomjs-1.8.1/bin/phantomjs highcharts-convert.js -infile config.json  -outfile out1.png -width 300 -scale 2.5 -constr Chart -callback callback.js

Error-

Things to check-
1. The following 3 files should be there in same folder or you have to set the paths to these here-
var config = {
                /* define locations of mandatory javascript files */
                HIGHCHARTS: 'highstock.js',
                HIGHCHARTS_MORE: 'highcharts-more',
                JQUERY: 'jquery-1.8.2.min.js'
        },

2. The 'infile' parameter should have an extension of .json, because that is what it uses to decide between svg input and a configuration json.

Virtualbox-Windows 8 developer preview installation error

Downloaded the Windows 8 developers preview yesterday but only to find I could not get it installed on a Oracle Virtualbox. I tried both 32-bit and 64 bit version on a Win 7 64 bit machine(HP EliteBook 8440p). The 32-bit got stuck at the following screen. I need to look for help on this error 0x81B8C63B

EDIT: From "Smiley"'s comments below, after I turned the Virtualization option ON from the BIOS menu at startup, I was able to install windows 8. Thanks.
Surprisingly, I have a Ubuntu virtual machine and it runs fine without turning on the Vitualization option.

Iphone 4 does not mount on Ubuntu after iOS 4.2 upgrade - DBus Error

After I upgraded my iphone to iOS 4.2, I was not longer able to mount it on Ubuntu 10.10. Whenever I got plugged it in, I would get an error message -
DBus error org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus)


I looked it up and found a workaround, seems like I need to update to a newer version of libimobiledevice.

Here is how I did it-

Unplug the iPhone and execute the following in the terminal window.

sudo add-apt-repository ppa:pmcenery/ppa
sudo apt-get update
sudo apt-get upgrade

sudo apt-get install libimobiledevice-utils

After the above install, plug in the iphone and execute -

idevicepair unpair
idevicepair pair
idevicepair validate

That was it and we are back with Iphone on Ubuntu.

Compiling Ganglia - Errors and problems

Some errors and problems:


My install directory was /opt/ganglia.


Error -
checking for gcc... no
checking for cc... no
checking for cl.exe... no
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details.

Solution -
Add gcc bin path to PATH environment variable


Error -
checking for pcre.h... no
checking for pcre_compile in -lpcre... no
libpcre not found, specify --with-libpcre=no to build without PCRE support

Solution -
PCRE is not installed.
# wget ftp://ftp.sunfreeware.com/pub/freeware/SOURCES/pcre-8.10.tar.gz
# /usr/local/bin/tar -xzf pcre-8.10.tar.gz
# cd pcre-8.10
# ./configure --prefix=/opt/ganglia
# make && make install

Make sure you add, -I/opt/ganglia/include to CFLAGS environment variable
and -L/opt/ganglia/lib to LDFLAGS after this.


Problem -
Graphs not shown in ganglia or images not shown on ganglia front end.


Reason -
php-gd may not have been installed.
You can do so by ( as root) -

# yum install php-gd

Another reason could be front-end can't find RRD path. Make sure it is set in conf.php


Error -

checking for apr-1-config... no
configure: error: apr-1-config binary not found in path

Reason -
APR is not installed or path of apr-1-config is not available through the PATH environment variable.


Error -
libgcc_s.so.1: open failed: No such file or directory


Solution-
Execute the following:
# ldd gmond
...
libgcc_s.so.1 => (file not found)
...


So gmond can link to libgcc


Add the following to you LDFLAGS
# setenv LDFLAGS $LDFLAGS:-R/yourgccpath/gcc-4.0.3/lib


-R records the runtime search path.


Install again
# ./configure --prefix=/opt/ganglia --sysconfdir=/opt/ganglia/etc
# make && make install


Error -
After installation, while executing gmond
apr_pollset_create failed: Invalid argument

Solution -
In your config file gmond.conf, if there is no udp_recv_channel or tcp_accept_channel
defined, gmond fails to run with this error.
Set "deaf = yes " under "globals"

Error -
/usr/bin/ld: cannot find -lpython2.3
collect2: ld returned 1 exit status
make[4]: *** [modpython.la] Error 1

Solution -
I dont remember exactly how i resolved it.
Most likely it was the linker not being able to find python.
Probably by setting library flags this error was resolved.

Error -
false cru libgetopthelper.a getopt1.o getopt.o getopt_init.o
make[2]: *** [libgetopthelper.a] Error 1

Solution -
Add /usr/ccs/bin to PATH environment variable.

In case of dependency not found errors, you could configure options, like --with-libapr, --with-libconfuse to point to dependency paths.

Error -
Some gm_protocol_xdr.c related warnings and finally build fails with this error

ld: fatal: relocations remain against allocatable but non-writable sections
collect2: ld returned 1 exit status

Solution -
Uninstall the dependency 'confuse' and install it by setting CFLAGS="-O3 -fPIC"
> cd ../confuse-2.7/
> make uninstall
> make clean
> env CFLAGS="-O3 -fPIC" ./configure --prefix=/opt/ganglia
> make && make install

Do a configure, make and make install and you should be good.
 

Ganglia - Basic installation and configuration guide

After playing around, with both Zabbix and Ganglia, I decided to go ahead with Ganglia. The installation is tricky but once it is installed, configuring and adding hosts is easy. Here I will discuss, installation and configuration of Ganglia. Both the client and server daemon will be installed on the same machine.


Ganglia is a monitoring system for high-performance computing systems. Ganglia comprises of two daemons. The daemon gmond, acts like a client and sends machine information( as xml fomat), to daemon gmetad which stores these statistics in a round robin database.


A PHP-based web frontend is used to dispay the graphs in near real time.
Before starting Ganglia a few dependencies are required to be installed.

# tcsh

# setenv INSTALL_DIR /opt/rrdtool-1.4.4

# setenv BUILD_DIR /opt/build/rrdbuild

# cd $BUILD_DIR  

# wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.4.4.tar.gz 

# gunzip -c rrdtool-1.4.4.tar.gz | tar xf – # cd rrdtool-1.4.4

# ./configure --prefix=$INSTALL_DIR && make && make install

This would have installed round robin database. It is required only on the head node. The head node (server) would be the one where you want to install gmetad daemon.
Another dependency required for Ganglia is libconfuse.

# cd /opt/build
# wget http://bzero.se/confuse/confuse-2.6.tar.gz
# /bin/tar -xzf confuse-2.6.tar.gz
# cd confuse-2.6
# ./configure --prefix=/opt/ganglia
# env CFLAGS="-O3 -fPIC" ./configure --prefix=/opt/ganglia
# make
# make install

Now we download Ganglia source package and begin installation.

# cd /opt/build/ 

# wget http://sourceforge.net/projects/ganglia/files/ganglia%20monitoring%20core/3.1.7/ganglia-3.1.7.tar.gz/download 

# tar -xzf ganglia-3.1.7.tar.gz 

# cd ganglia-3.1.7  

# setenv CFLAGS "-I/opt/ganglia/include/ -I/opt/rrdtool-1.4.4/include"  

# setenv LDFLAGS "-L/opt/ganglia/lib/ -L/opt/rrdtool-1.4.4/lib"  

# ./configure --prefix=/opt/ganglia --with-gmetad --sysconfdir=/etc/ganglia  

# make  

# make install

Make sure the permissions are appropriate on path /opt/ganglia/rrds. This is the path where I have my round robin database.

# cd /opt/ganglia/sbin/

# ./gmond --default-config > gmond.conf

# ./gmetad --default-config > gmetad.conf

Setup config files for gmetad and gmond.conf
# vi gmond.conf

Set up your udp_send_channel to look like this:

 udp_send_channel {
  host = masterhostname
  port = 8650
  ttl = 1
}
# vi gmetad.conf

Modify directives as:

data_source "MyCluster" localhost

rrd_rootdir "/opt/ganglia/rrds"

# cp gmond.conf /etc/ganglia/.

# cp gmetad.conf /etc/ganglia/.

# cd $BUILD_DIR
# cp gmond/gmond.init /etc/rc.d/init.d/gmond

# vi /etc/rc.d/init.d/gmond

Set this variable as
GMOND=/opt/ganglia/sbin/gmond


Optional (this would enable running the daemons as an automated service) :

# chkconfig --add gmond

# chkconfig --list gmond
gmond 0:off 1:off 2:on 3:on 4:on 5:on 6:off

# /etc/rc.d/init.d/gmond start
Starting GANGLIA gmond: [ OK ]
# cd /opt/build/ganglia-3.1.7/gmetad
# cp gmetad.init /etc/rc.d/init.d/gmetad
# vi /etc/rc.d/init.d/gmetad


GMETAD=/opt/ganglia/sbin/gmetad


# chkconfig --add gmetad

# chkconfig --list gmetad
gmetad 0:off 1:off 2:on 3:on 4:on 5:on 6:off


# /etc/rc.d/init.d/gmetad start
Starting GANGLIA gmetad: [ OK ]

Edit httpd.conf


Add the following lines if they are not a part of your config file.

LoadModule php5_module modules/libphp5.so

Edit DirectoryIndex like

DirectoryIndex index.html index.html.var index.php
Addtype application/x-httpd-php .php

AddType application/x-httpd-php-source .phps

Copy “web” folder to httpd document root location


Edit conf.php in web folder:
define("RRDTOOL", "/opt/rrdtool-1.4.4/bin/rrdtool");


RRDTOOL should point to rrdtool path

# /sbin/service httpd restart

You can point your browser to the web front end location and it should display you the graphs.
