Knowing what hardware is connected to your (or your clients) office network is obviously good to know, for one thing if you’re charging clients by the number of assets managed you’ll obviously make more money with more assets! Another reason is security – you don’t want stray systems sitting around unsecured/unpatched waiting to be hacked.
Knowledge is power and so proper documentation for every asset is essential to ensure they are maintained properly. Manually keeping track of all the company IT assets might be ok in a very small office with just a few machines which can all be seen from one place but for anything larger, with many machines which can change frequently and new ones arriving all the time, automation is the name of the game.
Fortunately there are a number of tools which make the job of asset discovery or network discovery very simple and which provide data which can then be imported or integrated with asset management or PSA applications.
If you have 100k assets to manage (and your pockets are very deep) then you may need something ‘enterprisey’ such as IBM Tivoli or the HP Configuration Management System, or so their sales people will tell you anyway. For the rest of us there are slightly more down to earth and affordable alternatives, including ones for free.
Open-AudIT is a network auditing application which works with Windows and Linux machines and will find out exactly what is on your network. Data is stored in MySQL and can be exported to PDF, CSV and other formats and reports can also be generated if needed. The word “open” in the name is a clue – it’s all open source (and free!) so you can see what is going on in the code if you feel the urge to look inside.
OCS Inventory NG is another free application which will scan your network and produce a detailed inventory of every device found which can then be imported into other applications as required.
Long a favorite of script kiddies and hackers everywhere but also of course a very useful admin tool is Nmap. It comes with command line and GUI options and can quickly scan entire networks then output the results in XML format (or even a special script kiddy format!) so it can easily be parsed and imported elsewhere.
Automated asset discovery of one kind or another is also commonly included in network monitoring systems such as OpenNMS as well as various RMM services and these can be particularly useful if they also integrate with your PSA application.
Using the tools mentioned above makes it easy to keep on top of your IT assets and ensure the smooth running of the networks and hardware your clients hire you to manage.
