Can I import my MRTG config files and data into Cricket ?
Short answer is NO. Cricket configuration tree is completely incompatible with MRTG config file. Also MRTG stores measurements in text files while RRDtool uses binary files. In theory it is possible to write a script which will convert MRTG config files into cricket subtree, parse MRTG data files and fill up relevant RRD data file. In practice, no one bothered to do this yet.
