Kill idle Redis connections

hitman.lua

local l = redis.call('client', 'list')
local k = 0

for r in l:gmatch('[^\n]+') do
  for c,i in r:gmatch('addr=(.+:%d+).*idle=(%d+).*') do 
    if tonumber(i) > tonumber(ARGV[1]) then
      redis.call('client', 'kill', c)
      k = k + 1
    end
  end
end

return(k)

To use, save into a file (e.g. hitman.lua) and run as follows:

redis-cli EVAL "$(cat hitman.lua)" 0 300

In this example, connections that have been idle for more than 300 seconds will be killed. The script returns the number of clients killed.

Yeah, this won't work anymore because CLIENT KILL isn't allowed from scripts.

There is a python a script here
