How to Monitor Your Windows 2008 Server on GoGrid with Cacti 0.8.7g

Tuesday, June 14th, 2011 by

This is the 3rd and final post in my setup and use of the GoGrid Community GSI server for Cacti Monitoring. In my first post, “Set Up A Cacti Monitoring Server in Minutes with this GoGrid Community Server Image,,” I covered how to deploy Cacti in your GoGrid environment using a Community GSI. My second post, “How to Monitor Your Ubuntu Server on GoGrid in 6 Steps Using Cacti 0.8.7g,” I discussed how to initiate monitoring of your GoGrid Ubuntu server. Now to round things off, I want to show you how to link up your Cacti monitoring server to a Windows Server 2008 server on your GoGrid network. The base install of Cacti 0.8.7g will allow you to monitor the server’s bandwidth utilization, Ethernet errors, number of logged in users, and total number of processes. There are other templates available to monitor other components and services on your Windows server, but they require using an additional SNMP service beyond the Microsoft SNMP service. My blog post won’t get into the latter, but I will cover the former.

Objectives:

  1. Configure GoGrid private network connectivity on Windows 2008 Server and test connectivity to Cacti server
  2. Configure and start Microsoft SNMP service on your Windows 2008 Server
  3. Add new Cacti device
  4. Create graphs to log Local Connection and Local Connection 2 bandwidth and errors, Logged in Users, and server processes

Configure GoGrid private network connectivity on Windows 2008 Server and test connectivity to Cacti server

Below we see that we have a server (“Web2”) deployed on GoGrid with a public IP. Let’s log into this server and configure the private network with a private IP from the same subnet of the Cacti Monitor server. As I described in my previous post – I am using the prescribed private IP subnet from my GoGrid portal, contained under the List tab and then under Network – Private Network.

How To Monitor your Ubuntu Server on GoGrid in 6 Steps Using Cacti 0.8.7g

Wednesday, June 1st, 2011 by

In my previous post, “Set Up A Cacti Monitoring Server in Minutes with this GoGrid Community Server Image”, I showed how to use a Community GSI to quickly and easily set up a monitoring server on GoGrid running Cacti. In this second part of the Cacti GoGrid Community GSI blog series, I would like to walk you through how I connected my Cacti server up to an Ubuntu server (a node in my Glusterfs file storage array). First we will review the objectives we are looking to achieve and then dive into each one.

Objectives:

  1. Confirm private network configuration on both Cacti server and Ubuntu server, and test connectivity.
  2. Enable SNMP server and configure SNMP rocommunity string on Ubuntu servers.
  3. Establish SNMP agent listening IP address
  4. Create “Device” in Cacti console and confirm SNMP connectivity to Ubuntu server
  5. Create Graphs – CPU usage, Load Average, Memory Usage, PING Latency, Processes, Eth0 Traffic, Eth1 Traffic
  6. Repeat process for other Ubuntu servers in your network.

Confirm private network configuration on both Cacti server and Ubuntu server, and test connectivity

On GoGrid, you have the ability to network your servers together over a private network allocated to your account. (Note: all private networking within GoGrid is free.) We need to take advantage of this secure communication method to allow your Cacti server SNMP access to your servers. I recommend you use the private network IP range that is specified in your account – under the “List” tab then “Network”.

Set Up a Cacti Monitoring Server in Minutes with this GoGrid Community Server Image

Thursday, May 19th, 2011 by

One of the best open-source tools ever created and maintained is Cacti. Cacti can be used to monitor and log critical information for your servers, applications and other network devices. The monitored data can be graphed in a variety of ways and becomes a valuable resource when troubleshooting problems and projecting future resource utilization.

However, the initial configuration can take hours to complete, not including the server OS install process and pre-configuration.

Deploying Cacti Easily in GoGrid

To make this process a bit easier for GoGrid users, I have performed the routine installation of Cacti 0.8.6 along with the package requirements within a Community GSI (GoGrid Server Image). Also, I have added DenyHosts for added system level protection. The ssh_banner will provide the details of what was configured on the system. All that needs to be done is going into your account within the GoGrid portal, clicking on the Add button and filter for “Cacti”.
