Hi folks, this post is another form I created using the Calculated Fields Form plugin for WordPress. Basically, this simple form calculates the number of devices input in the form fields and multiplies the number of devices by the designated Events Per Second (EPS) average for each device type. It then provides a live calculation of total number of devices, total average EPS and total average Events Per Day (EPD).
This handy calculation can then be used on my other calculator NetCerebral’s Simple Log Storage Calculator as the average EPS, need as the primary input to calculate amount of storage and IOPs required for the EPD and retention periods defined.
The following form assumes you have done the preliminary math of determining your number of devices and the total anticipated Events Per Second (EPS) you will be collecting from all of your logging devices. The calculator uses EPS to determine the Events Per Day (EPD), amount of raw and normalized log data you will generate daily and then use retention and compression values you set to determine the required amount of storage as well as IOPs required.
Stay tuned and I will be building another calculator that will allow you to specify number of devices by device type, which will give you your estimated EPS (needed as a starting point for this calculator).
