00:28:09 GMT <mful> hey all! anyone around?
06:18:53 GMT <PSUser2> how do i find the zset names from a database?
06:19:20 GMT <hai> test test
14:04:42 GMT <spydon1> Hi ho, my redis machine (which runs in a mesos cluster) keeps on eating more memory than maxmemory and crashes, is there any more parameters that I have to set to make it start evicting stuff in time? I set the maxmemory-policy to allkeys-lru
14:08:20 GMT <spydon> http://pastie.org/private/u4vvhbqflvvonchgcq5bca
14:11:39 GMT <spydon> It's version 3.0.2
14:42:44 GMT <spydon> The used memory is 6gb in info and the limit is set at 8, but the redis-server process just contantly goes up in memory, it is at 18gb now
17:19:54 GMT <minus> are you perhaps looking at virtual memory?
17:55:11 GMT <spydon> minus: I don't think so, then it wouldn't crash, right?
17:55:43 GMT <spydon> It also makes backups to disk, I just realized. But those that tripple the memory usage...?
17:56:00 GMT <minus> it forks for backups iirc
17:58:20 GMT <minus> virtual memory doesn't really matter; if you want the real size in memory look at RSS
18:36:15 GMT <c2nes> spydon: what does redis INFO report for RSS size and fragmentation?
18:54:27 GMT <spydon> Ah, the paste site died, how reliable
18:55:57 GMT <spydon> mem_fragmentation_ratio:2.88 ?
18:56:08 GMT <spydon> I don't find anything called RSS size
18:56:53 GMT <c2nes> You should see something like,
18:57:01 GMT <c2nes> used_memory_rss:3952640
18:57:16 GMT <spydon> used_memory_rss:18518106112
18:58:10 GMT <c2nes> I don't remember off hand, but maxmemory settings may apply against the non-rss number
18:58:22 GMT <spydon> What is rss?
18:58:48 GMT <c2nes> Basically the amount of memory allocated to redis by the operating system
18:59:13 GMT <c2nes> It can be higher than used_memory when blocks of memory are used inefficiently
18:59:18 GMT <spydon> Ah, yeah, that number is the same as what top reports
19:01:20 GMT <c2nes> There's some info here, http://redis.io/topics/memory-optimization
19:01:31 GMT <c2nes> Look under the "Memory allocation" heading
19:02:54 GMT <spydon> I don't really need to optimize it, I just need to know approximately how much memory I should throw on the machine. There is like an infinite amount of memory available in the cluster and I'
19:02:59 GMT <spydon> m not paying ;)
19:03:14 GMT <c2nes> Haha, that makes things easy then
19:03:35 GMT <spydon> But interesting to read anyways
19:03:48 GMT <c2nes> Yeah, unfortunately fragmentation will be dependent on usage patterns. Just monitor your typical ratio and allocate appropriately
19:04:03 GMT <spydon> Will do
19:04:30 GMT <spydon> Thanks a lot :)
19:04:46 GMT <c2nes> np
19:08:14 GMT <spydon> If battlefield 1 crashes during launch now, I'll blame everything on you ;) "There was this c2nes guy on irc..."
