Right now at http://tools.wmflabs.org/?status are separate tables for every virtual machine sorted by date the task was started.
There might be other tools for tool labs (sysops) that I dont know of, but I think that for monitoring tools parameters would be useful to be able to sort the tables according to other parameters than just date added - e.g. CPU and VMEM.
Another enhancement that would be nice to have is the ability to sort the table of virtual machines according to their load, memory and free vmem.
Last proposal would be the possibility to have a table of all tools from all virtual machines that would be also sortable according to CPU and VMEM.
I have no idea how time consuming the implementation of these would be, but I see these as potentially useful.
