There are two graphs added:

Bandwidth – Shows the current set bandwidth limit and usage figures for a Zone Access Point
Calls – Shows the number of calls both accepted or rejected by Bandwidth Management

To install just copy the “mitel_bwmgt_stats.xml” file into your cacti “resource/snmp_queries” directory. Then import the host template file into Cacti (Minimum Ver 0.8.7d). Once that is done you should be able to add the Mitel graphs to your monitored Mitel hosts.

Requirements

• Cacti – 0.8.7d
• SNMP Enabled on the Mitel Controller

Download

• Mitel Bandwidth Management Cacti Graphs

You will need your linode account number to use the graphs, you can find this number by looking at the graphs provided to you in your Linode account management interface. The title of the graph will be “http://www.linode.com/ – yourhostname (linode12345) – CPU – …….”. You will need the text from inside the ( ) for your username ie linode12345.

To install just copy the linode.pl file into the scripts directory of your Cacti installation. This script was taken from http://www.linode.com/forums/viewtopic.php?t=776 and modified for use with cacti.

Then just import the cacti host template file into Cacti. You should then be able to add the graphs to your relevant host.

Requirements:

• Cacti 0.8.7d
• Perl XML::LibXML
• Perl LWP::UserAgent
• Perl IO::File

Error: XML: Hash version does not exist

This simply means the template was generated on a version of Cacti newer than the one you are importing to. Don’t despair, there are simple upgrade instructions on the cacti website.

Just make sure you make a full backup of your database and Cacti webfiles before attempting the upgrade (As a cautionary tale, if you installed cacti from a package you should first check to see if an updated package is available. Package installs can sometimes put the different files required in different places)

My main objective when I started looking into disk monitoring was to get some similar stats into Cacti for Linux that can be found with the Windows PerfMon utility. I found Mark’s post and didn’t quite like the way it used cron to collect its statistics, and wanted something that I could easily add to snmpd.conf without needing to change much more. I was also keen on obtaining the mount point data for each partition as looking at “cciss/c0d0p3″ doesn’t mean as much to management (and sometimes to me) and hopefully “/home” does.

So I wrote a script which uses the output from “df -l”, “vmstat -d”, “iostat -dk”, “iostat -xdk” to produce the results I wanted. This script only looks at the individual partition on the disk. Some of the stats don’t work with Software RAID, and some stats are missing for some older versions of the kernel when used with a HP Hardware RAID card (this is all I have tested with). These are the results.

Requirements:

• sysstat package
• Net-SNMP
• Tie::IxHash perl module
• Cacti (Ver 0.8.7d minimum)

Installation:

1. Make sure you have the requirements installed.
   Tie::IxHash comes as a package on both Debian/Ubuntu and OpenSUSE and at the very least you could install it using CPAN.
   Sysstat also should come prepackaged for most Linux Distros.
2. Copy the “disk_stats.xml” file from the archive into the “resource/snmp_queries” folder of your Cacti installation.
3. Copy the “disk_stats.pl” file to your “/usr/local/bin” directory and run “chmod +x /usr/local/bin/disk_stats.pl“.
4. Edit your “snmpd.conf” file and add the following line “pass .1.3.6.1.4.1.2021.51 /usr/bin/perl /usr/local/bin/disk_stats.pl” (If that OID conflicts with another OID on your system you need to change the value used both in your snmpd.conf file and in the disk_stats.pl file. You will need to restart SNMPD after this change.
5. Import the “cacti_data_query_snmp_-_disk_stats.xml” file into your Cacti installation using the “Import Templates” menu option.

You should now be able to open a device and add the “SNMP – Disk Stats” in the “Associated Data Queries” section.

VMWare ESXi 3.5 CPU Graph in Cacti

VMWare ESXi 3.5 Memory Graph in Cacti

This method uses the VMWare Remove CLI tools to connect to the ESX server and download the information via an XML interface.

Software Required:

• Download the VMWare Remote CLI from http://www.vmware.com/go/remotecli
• Cacti http://www.cacti.net/

Firstly download and install the VMWare Remote CLI tools to your Cacti server.

Next you need to add a user to ESX for the statistics collection.

On the ESX Virtual Infrastructure Client goto the “Users & Groups” tab.

VMWare ESXi 3.5 Add Stats User Step 1

Right Mouse Click and “Add” a new user.

VMWare ESXi 3.5 Add Stats User Step 2

Then go to the “Permissions” tab, and Right Mouse Click to “Add Permission”.

VMWare ESXi 3.5 Add Stats User Step 3

Add the new StatsUser and select Read-Only for the assigned role and click Ok.

Now goto your Cacti installation and copy the “esxstats.pl” file into your cacti scripts directory and import the “cacti_host_template_vmware_esxi_3_5_host.xml” file into Cacti using the web interface. These scripts can be downloaded from the bottom of this post.

You should now be able to add a new ESX host into cacti. You will need to specify the “Downed Device Detection” mode to just “Ping” as there is no SNMP on the current Free version of VMWare ESXi 3.5.

I am hoping that SNMP support will come to the free versions as that would make life much easier.
