What admin tool do you guys use? Procon?

So when you suspect some1, then use procon for this.

When you use procon you can see the map from above (you need to be 1 of the highest admins on procon), here you can see the players who are the killer and who is killed.
With what weapon, headshot and etc.

Normally if you have a cheater you can see this.
They kill 3 to 5 guys in a few secondes, then they don't kill for a few minutes and after that they kill again 3 to 5 guys in a few secondes (and 90% of the kills are headshots).

I've seen this on my own servers.
