Excel and HTML Asset Reports With Powershell

This set of powershell functions collates and generates reports upon system information it gathers. Information gathered includes hardware health, system information, networking information and much much more. Multiple types of html reports can be generated and all data can be exported directly to an excel workbook, saved as individual reports, and emailed.

The reports offer a high level of data customization and currently come with two example data sets. One for daily system reports which contains less overall information. And another, far more inclusive, system documentation report. The html output can be highly customized as well. Currently there is a dynamic grid html report based on responsive design templates as well as a less glitzy email capable html format. The report data can also be returned directly to an excel workbook where several sheets will automatically populate and be formatted for easier reading and further manipulating.

Notes

I suppose I’ll upgrade this from beta status to non-beta, or whatever comes next. I’m mostly happy with the report layout and formatting for the DynamicGrid template. I’ve also breached new ground with a whole new set of data results for inclusion in the asset reports (with a recently released set of functions for returning the results of a remotely run command via alternate credentials). The EmailFriendly format still needs some attention but should serve its purpose.

While the reports are pretty, I think that the real value to professionals is in the excel export this script can automatically generate. You can determine a whole lot from the information this script gathers. You can quickly isolate nic cards in promiscuous mode, find servers using strange license keys, and more.
