There are many other tools available to collect resource usage of running programs on the system such as [[Bell Lab]]’s strapon tool and [[Dyninst]] tool etc. [[Bell Lab]]’s tool uses the strap on technology which runs a tool to collect resources simultaneously with the program but this tool is only compatible with the programs which allow other programs to run simultaneously with them.<ref>{{Cite journal|url = |title = Building secure products and solutions.

However, it is very unstable as it is a relatively new tool and crashes on large scale programs.<ref>{{Cite journal|url = |title = Dynamic binary instrumentation and data aggregation on large scale systems|last = Lee|first = Schulz|date = 2007|journal = International Journal of Parallel Programming|doi = |pmid = |access-date = }}</ref> Lastly, [[Intel]] Pin tool uses static binary instrumentation and runs the program as a part of itself while keeping track of all its resources.<ref>{{Cite journal|title = Analyzing Parallel Programs with PIN|url = http://ieeexplore.ieee.org/lpdocs/epic03/wrapper.htm?arnumber=5427374|journal = Computer|date = March 2010|access-date = 2015-04-27|issn = 0018-9162|pages = 34–41|volume = 43|issue = 3|doi = 10.1109/MC.2010.60|first = M.|last = Bach|first2 = M.|last2 = Charney|first3 = R.|last3 = Cohn|first4 = E.|last4 = Demikhovsky|first5 = T.|last5 = Devor|first6 = K.|last6 = Hazelwood|first7 = A.|last7 = Jaleel|first8 = Chi-Keung|last8 = Luk|first9 = G.|last9 = Lyons}}</ref> This approach is more suitable for an antivirus as it can easily run all the processes under itself and can kill programs if they reach a maximum allocated limit as defined by the antivirus.
