comment Understanding difference between system and process memory in htop
I've updated the question with the output from free - will try to post a screenshot later. free is reporting about 5.4GB in use / 2.7GB available. I'm under the impression that htop generally shows higher memory usage than other tools, so I guess htop must mean 456MB free as you say, still, it seems very low.

In that case, it would be the opposite convention to the swap usage shown directly under it (currently showing 0/2074 with no swap file usage) - are you sure?

comment How to reproduce read ETIMEDOUT with node_redis on my local dev machine?
Thanks. The problem Is I'm on windows for dev, so don't have iptables - but perhaps I'm going to have to connect to a remote redis.

You shouldn't really be running node as root in production

@gladoscc - Did you figure this out in the end?

comment Blacklisting client IP addresses with haproxy
I see, right. Perhaps iptables would be the place to do it then?

comment Very high disk IO on Mongodb Config servers
Sorry, just one more question :) - Since the mongos clients decide the activity on the config server, is it neccesary to add quiet=true to the mongos configs if I want to reduce logging on the config servers?

comment Very high disk IO on Mongodb Config servers
Every member of each shard replica set is 2.4.5. I don't think there's much in the way of migrates happening either, as writes are very low on the cluster at the moment. I haven't looked the config.changelog before though, so will check this out. Thanks!

comment Very high disk IO on Mongodb Config servers
Ah, good to know. So after upgrading those mongos clients the disk activity on the config servers has fallen by about 50%. It still seems a little on the high side to me, but a vast improvement! Thanks.

comment Very high disk IO on Mongodb Config servers
Thanks. I'm running 2.4.5, and also have quiet=true in the configuration file (I'm assuming that is the same as the --quiet flag). I've restarted all of the processes in my cluster to no avail. I've just noticed that some mongos processes on the app servers (not part of the mongodb cluster) are running 2.4.3 though - perhaps this is the issue...

comment Identifying particular node processes in htop
It's the same binary unfortunately, processing different scripts. The open files route is an option I hadn't considered, and might be doable. Thanks!

Ah - missed the check. I'll add that and see (the default url should be ok, but I've explicitly added one now anyway). Thank you.

comment Possible to add basic HTTP access authentication via HAProxy?
+1 Just wanted to add that you can also add the final lines in a frontend definition rather than backend if you want. And the realm xxxx part is optional.

comment iptables Tips & Tricks
Re the whitelist script: Theres iptables on line 8, and then $IPTABLES later on. Is it enough just to use iptables everywhere? Otherwise I suppose you'd need to assign something like IPTABLES=/sbin/iptables right?

comment Can I use IPs assigned to virtual network interfaces in a bash script?
It seems it returns both IP addresses assigned to the interface whether I use eth0 or eth0:0. If the order is guaranteed though, perhaps I can just select the right one from the string.

Interesting - I'll have a play around with that. Thanks.

comment iptables Tips & Tricks
That's a real pity it's not supported by default on Debian and Ubuntu. I thought you were going to list some obsure distros :/
