Ever heard of Alyvix ? That’s a free environment for monitoring application performance by emulating an end-user interacting with the real application. I’ve created a monitoring agent for the QAD/ERP software that allows one to measure the login time as well as the performance of different programs and queries throughout the day from an end-user perspektive. The data can be retrieved from the Monitoring workstation using a REST gateway in order to be displayed within Cacti.
Look at the attached graphs for the result:
Cacti has a great polling engine for retrieving SNMP, WMI and other data from a lot of different devices. It generally stores the data into RRD files which are then being used to create the actual graphs for the users to view. By using InfluxDB together with Grafana as a frontend, it is possible to built an easy to use performent dashboard for end-users utilizing the Cacti polling engine.
CereusAgent v1.03 has been released. This new exciting addon for Cacti allows you to create as many stand-alone pollers as you require while being able to centrally manage these. No permanent connection is required after the initial configuration/setup so you can place a poller on a customer site ( e.g. SOHO, remote offices ) and collect the data once a week.
Sometimes during the upgrade process, not all required columns or table may have been added to the database. This error may manifest itself with an “Error: Save failed” message when trying to save changes to a device.
A possible fix to this is to manually call the upgrade.php script. To do this, go to the command line and change to the thold plugin. Then call the upgrade script:
cd /path/to/cacti/plugins/thold php extras/upgrade.php
Then re-try saving a device. You will see the following messages:

This post will show you how to install the VMWare Perl SDK on CentOs 6 and CentOs 7
CentOs 6 / SDK Version 5.1
The following commands will install all necessary perl modules on a Centos 6 system required for the SDK .
rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-7.noarch.rpm yum install gcc perl-CPAN perl-Archive-Zip perl-Class-MethodMaker perl-SOAP-Lite perl-XML-SAX perl-Crypt-SSLeay yum install perl-XML-NamespaceSupport perl-XML-LibXML perl-Data-Dump uuid-perl libuuid-devel uuid-devel wget --directory-prefix=/tmp http://search.cpan.org/CPAN/authors/id/J/JN/JNH/UUID-0.04.tar.gz tar -zxvf /tmp/UUID-0.04.tar.gz -C /tmp cd /tmp/UUID-0.04 perl Makefile.PL make make install
CentOs 7 / SDK Version 6.0.2
We’re going to install version 6.0.2. You should have downloaded the required file to the /tmp directory already. The following section will show you of installing the required modules. The actual install will ask you to accept the license terms and choose an install directory. It will also ask you for the permission to install the pre-built binary files for the required perl modules. You can accept all the default settings.
yum -y install openssl-devel cd /tmp tar -xzvf VMware-vSpehere-Perl-SDK-6.0.0-3561779.x86_64.tar.gz cd vmware-vpshere-cli-distrib ./vmware-install.pl
