I have a Cacti NMS running on my network and need someone knowledgable with rrdtool for a very short and simple task. I will require more tasks right after this one and will assess how suitable you are based on your performance with this task.
For this task, you'll need to create a very short & simple script that will call on RRDTool to export data from an RRA file & average it. The script should accept the following input before fetching and doing its averaging calculation:
What RRA file to use
Time-range/date-range (specified in DD/MM/YYYY and not since last epoch)
You may choose between PERL or BASH to write your script
The script is very short and simple and will allow me to see how you will perform in future and more demanding tasks. The time it takes you to deliver a solution will also be taken into consideration.
P.S: Once you're hired, ill provide you with the RRA files and the time-range/date-range
