Hi, I have been trying to use json filter. In the documentation, it says that I can make my filter using json hints. JSON filter has its own pre-defined variables like $free_ram_mb, $free_disk_mb etc. I was wondering if it is possible to define other variables, so that I can define a filter suiting my needs? If yes, then where should the new variables be defined? Thanks ~Peeyush Gupta -------------- next part -------------- An HTML attachment was scrubbed...
