mossy

current total system usage?

Matt Bear

7gb of 7.5

mossy

@ScottPack correct me if i'm wrong..

The virtual field that you're looking at is the total mem that the specific process could use

@MattBear post again

Matt Bear

@mossy what?

freiheit

@MattBear Looks like a LAMP server to me. :)

strugee

@MarkHenderson ... :P

Matt Bear

@freiheit yup, well SugarCRM, but yeah

Mark Henderson

I think @Jacob was about 14 when he started chatting in here

strugee

00:14

how old is he now??

Mark Henderson

We have thoroughly destroyed his soul and his faith in humanity over the past few years

mossy

I remember one day he changed his pic from 10 year old @Jacob to man @Jacob

Matt Bear

@MarkHenderson isn't that what happens when you work in IT anyway?

freiheit

@MattBear PHP and MySQL, so, yeah, from the server side it'll look an awful lot like drupal, wordpress, moodle, etc... You got innodb file per table on? You figured out how much memory tends to actually be used and tuned httpd to max out at that many processes? Loaded and enabled APC?

Mark Henderson

@MattBear Touche

@mossy My G+ photo is me when I was 9

I'm hoping it brings all the pedos to the yard

freiheit

00:16

@MattBear Sometimes it doesn't take years...

Matt Bear

@freiheit I haven't done anything besides have it handed to me... and been told "performance sucks"

strugee

too bad I don't have a soul to be destroyed. or faith in humanity to be crushed

I feel so left out

Matt Bear

@strugee well then... now you just need a bike

freiheit

@MattBear Is there an APC package installed? Maybe an apc.ini hiding out in some PHP conf directory?

Matt Bear

:p

strugee

00:17

@MattBear haha yeah (I actually do though)

mossy

Probably using default MySQL config.

IIRC that's set to use just about everything that you have by default.

Matt Bear

@freiheit I do not believe so

freiheit

@MattBear @MattBear on a typical unoptimized Apache/PHP/MySQL stack, the biggest performance gain for the least effort will be to enable a PHP code cache. APC or some Zend cache thing... (there's a few options)

@MattBear The next most likely candidate is MySQL stuff, but that should mostly just be handled with turning on the slow query log to verify if that's even a problem at all.

All that is, of course, assuming you're not seeing heavy swapping

strugee

that would make a good canonical question on Server Fault

"where should I start to improve the performance of an unoptimized LAMP stack"

Matt Bear

@freiheit whats looking like the biggest problem to me.. is that the server is running all the time at 90%+ memory utilization

Scott Pack

00:21

@MattBear As reported by what?

freiheit

@MattBear Anything less than 100% is fine. Are you counting the "buffers and cache" as used?

Matt Bear

@freiheit yeah

@ScottPack free

strugee

@MattBear don't

freiheit

@MattBear What percentage is used if you look at the "-/+ buffers/cache" line?

Matt Bear

total used free shared buffers cached
Mem: 6853 6517 336 0 1179 3349
-/+ buffers/cache: 1987 4865
Swap: 0 0 0

Scott Pack

00:23

What those guys said. Look in the 'free' column under the buffers/cache line.

freiheit

@strugee One problem with turning it into a canonical question is that the APC answer is huge for running a lot of a single app, but not very useful for running a ton of different apps.

Matt Bear

4865 free

freiheit

@MattBear So, you have 7GB, are using 2 and the OS has cached the 4GB worth of disk it actually touches?

Scott Pack

Matt Bear

freiheit

00:26

@MattBear Without APC, ZendCache or something similar, you're reading and tokenizing/compiling ALL THE CODE for every hit against PHP. For a large PHP app (lots of libraries, etc) you can potentially shave a few seconds off the page load time with that kind of cache.

Scott Pack

@MattBear Looks like you have nearly 5 GB free to me.

freiheit

@MattBear Your memory is under 30% used. Use more! :)

Matt Bear

@ScottPack :ok, so its the free cache I need to worry about?

Scott Pack

@MattBear No. See how that line says "-/+ buffers/cache"?

Matt Bear

@ScottPack yeah

strugee

00:28

@freiheit ah

Scott Pack

That means that the free column is showing you how much is free + how much is in buffers/cache.

Matt Bear

@ScottPack ohh ok

Scott Pack

All of that is considered "soft allocated" or some shit like that. It's in use but will be purged if it's actually needed.

Unix like systems are good at saying, "Ohai guise! I see you have 16GB of total ram. Let me use every single drop of it for temp stuff if you aren't using it."

Matt Bear

so all those apache servers that are started are unused then, just allocated?

strugee

@ScottPack wasted RAM is wasted power

Scott Pack

00:30

Q: Why is Linux reporting "free" memory strangely?

This is a canonical question about how Unix operating systems report memory usage. Similar Questions: Server refuses to use swap partition Memory Usage in LINUX I have production server that is running Debian 6.0.6 Squeeze #uname -a Linux debsrv 2.6.32-5-xen-amd64 #1 SMP S...

There's the canonical.

Matt Bear

I think I knew that... lol

Scott Pack

Wait, no. I don't like that. I'm pretty sure I gave a good answer on free as well.

Matt Bear

so since this is one application, APC should help performance a lot?

Scott Pack

That one needs to be the canonical.

freiheit

@MattBear You need something like "apachectl status" to see which apache servers are actually in use at a given time.

Scott Pack

00:32

Related, but here's another.

freiheit

@MattBear APC could shave a second or two off of each PHP page load.

Scott Pack

@MattBear serverfault.com/q/67759/3356

freiheit

@MattBear Try using top to see the CPU usage of the httpd procs while you do something that's slow in SugarCRM. If it's something likely to be helped by APC, you'll see most of the CPU time going to a single httpd process and very little to mysqld.

Michael Hampton

Because your question looks unprofessional.

Matt Bear

from what I'm told, each page loads multiple views, so multiple queries are being run each time a page is loaded.

cole

Dumpin a 150GB MySQL table via mysqldump into a gzip pipe over SSH without using screen. Wish me luck.

Jacob

@MarkHenderson DOOOOOOOOOOM

@MarkHenderson Yeah so why no screen?

Kevin Soviero

Anyone here?

Jacob

@KevinSoviero nope

What's up?

Kevin Soviero

@Jacob Do you know where I can get sweat pants? I tried Kohl's, but they're considered seasonal, and it isn't the season for sweat pants.

Jacob

@KevinSoviero Erm, walmart?

Mark Henderson

03:57

@Jacob Don't even ask

Jacob

I mean you can get them at a fitness store but they'll be over priced.

Mark Henderson

@KevinSoviero Pretty much any department store that caters to cheap people

Jacob

@MarkHenderson Too late.

Kevin Soviero

@Jacob They wouldn't be seasonal there too?

@MarkHenderson Isn't Kohl's considered cheap?

Jacob

@KevinSoviero He's from Australia, nothing is cheap.

Mark Henderson

03:59

@KevinSoviero I don't know what Kohls is

Jacob

@MarkHenderson department store

Kevin Soviero

@MarkHenderson kohls.com

I use sweat pants as pajamas, and my current pair have no knees, bottoms, or butt region left... No sure what goes on while I sleep.

Mark Henderson

@KevinSoviero I do too

Quite comfortable and warm

Kevin Soviero

Anyway, I have to go take a shower before work tomorrow, night all!

Jacob

pajamas... useless

I loathe them

Mark Henderson

04:08

@Jacob I am way too scared to ask...

Jacob

@MarkHenderson about....

Bob

@MarkHenderson There was also that headline with a photo of a guy in a Guy Fawkes mask.

Mark Henderson

About what you sleep in if you don't wear pyjamas

@Bob Didn't see that one. I am avoiding most media

I will read SMH on my iPad but I skip most of the budget stuff

Bob

@MarkHenderson A very good idea :\

SMH is at least halfway decent.

Well, compared to this crap almost anything is decent.

Mark Henderson

@Bob Fuckin aye

My sister is getting pretty royally screwed by the budget. Her income is going down by $75/week and her daycare hours for her son are being cut from 15 to 10, so she can work 5 hours a week less on top of getting fewer benefits

(she is coming out of a messy marriage, so she's not exactly a huge burden on society)

So she'll have to pay more daycare fees to cover the gap so she can work to earn the money that the government took away from her

Bob

04:15

...fuck's sake

I still don't know what their excuse for doing this shit is.

Mark Henderson

Mr Abbott says she should just suck it up, but as a self-employed single mother who hasn't quite got her shit together after leaving her douchebag husband and he isn't paying any child support, and for the 15 years has paid her taxes and not been any burden, it's just not that simple

Bob

"fix the budget"? fuck off.

Mark Henderson

@Bob I know, right!

I'm mega pissed because I was forced to agree with Clive Palmer the other day

Jacob

@MarkHenderson Wow, like a no win situation. How did she lose 75/wk

Mark Henderson

Thanks Tony, for making me agree with Clive.

@Jacob Government is cutting benefits to pretty much everyone

Jacob

04:16

@MarkHenderson OH

Bob

@MarkHenderson oh yea, didn't he say he was going to run for PM?

now THAT was a WTF moment

<diety> help us all

Mark Henderson

@Bob bahaha yeah, the guy's a crackpot most of the time. But in his budget response he made more sense than Bill Shorten did

Too bad he doesn't get an official response :p

Basically we have the lowest debt per capita by percentage of GDP of anyone in the developed world

And most Australians don't really give a shit about having a surplus budget

We give a shit about being able to feed our kids

Jacob

@MarkHenderson Does your government cover higher ed tuition?

Bob

...get rid of gov debt by pushing it onto individual citizens (and probably several times the amount too)

@Jacob they did

now? kinda. maybe. sorta.

Jacob

@Bob in any form?

Mark Henderson

04:19

@Jacob Sort of. They give you a no-interest loan to pay for it (indexed at inflation). But they want to end that scheme, transfer everyone on that scheme to an interest-style plan, and un-cap university admission fees

Bob

they want to deregulate uni fees too

Jacob

I mean I'm looking at needing 100k

Bob

@Jacob that's going to be a very real possibility here in a couple of years

Mark Henderson

@Jacob They want to do that here. Currently university fees are regulated, but if they de-regulate it in 2016 that's exactly what will happen

Which means that my son might decide that university is not worth the excessive debt

(which is OK with me. I need an electrician in the family)

Jacob

@MarkHenderson If I could... I'd be an HVAC mechanic.

Bob

04:21

@MarkHenderson once again, I have no idea what their reasoning is

seems like they're trying to emulate the US in all the worst ways possible

Mark Henderson

@Bob Well we now have former PMs saying that we should cut ties with the US because they're basically fucking us over for no benefit

Jacob

@MarkHenderson How so?

Mark Henderson

@Jacob Dunno didn't really read it but basic gist was: We fight your wars, we back your trade deals, we side with you, but you don't really do much for us

Bob

@MarkHenderson well, the trade deals aren't exactly in our favour. or even neutral.

@MarkHenderson I guess the idea is they'll protect us if we're attacked, that kinda thing

bleh.

Mark Henderson

@Bob Yeah but if Tomorrow When The War Began is to be believed, only the Kiwis will come to our rescue :P

Oh yeah thats why we need $14bn of fighter planes too, right

Jacob

04:26

@MarkHenderson Whose going to attack?

Mark Henderson

Because we're constantly at threat of being invaded by like, the Timorise or something

Maybe New Guineans will invade us on bamboo rafts

Bob

@MarkHenderson the invasion of the boat people!

sad thing is, I could actually see that being a headline -_-

Mark Henderson

@Bob Right! Yes instead of turning them back or sending them to prison we'll just explode them

Works for me

Mark Henderson

Just got an EOL notice for HP LeftHand for if you're running their OS version of < LeftHand OS 2014 - but of course, all the lefthand stuff returns numbers like 9.1 and 10.5

Now I have to look up what number "2014" relates to

Goddamnit

Baha and they EOL non-2014 versions of the OS, but then their product page has a huge notice saying you can't install 2014 on G2 devices because of a crippling bug from November 2013

Fuck you HP

G'day

@MarkHenderson they abandoned that Lefthand platform

Mark Henderson

@ewwhite The G2 platform?

Super sad

ewwhite

Just Lefthand in general.

Mark Henderson

Really?

What is their SAN offering then?

ewwhite

because: 3par

Mark Henderson

Wait; they bought LeftHand, integrated their line, then bought 3Par and dumped LeftHand?

That... well that fucks me over

ewwhite

05:54

They have a 3Par offering that cannibalized the sales of their higher-end Lefthand units

Mark Henderson

They're still selling LeftHand units though

ewwhite

www8.hp.com/us/en/products/disk-storage/…

@MarkHenderson well, yeah... but the 3par is nicer/better/faster

Mark Henderson

@ewwhite But I can't integrate it with our existing P4000 shelves :(

Also: Yellow. Sexy.

HOLY SHIT

QR489A	HP 3PAR STORESERV 7200 16GB BASE SAN KIT						0	$48633

I'm not fucking made of money

That's 10x the price of an empty P4000 shelf with a 10GB upgrade

I think I will just stick with the LeftHand offering until they EOL the entire product line

ewwhite

they have many variants of the 3par

basically starting at 30k

Mark Henderson

My reseller only has the FC ones listed

Including this fucker

QW979A	HP 3PAR STORESERV 10800 RACK CONFIG BASE						0	$265236

ewwhite

05:59

well, it's high-end SAN gear

Mark Henderson

@ewwhite Yeah "starting" at $30k is more than our entire SAN has cost up to date

Jenny D

@Iain It is the current Kewlest Thing Ever

@JennyD seems that way

Dennis Kaarsemaker

@Iain it's the latest "I don't like config management, so let's just copy VM's around" thing.

@DennisKaarsemaker it certainly seems to be a thing right now

Colyn1337

Shit, I keep leaving this up

ewwhite

11:56

@Iain it's an expansion of my LXC and containers interest. I think Docker is making people happy.

@DennisKaarsemaker Do you think it's a bad idea?

Dennis Kaarsemaker

@ewwhite what does it add except overhead?

ewwhite

@DennisKaarsemaker Well, i don't know about docker specifically, but there doesn't seem to be much overhead with containers.

Dennis Kaarsemaker

@ewwhite so what do they add?

Iain

@ewwhite My comment was about the front page not chat

ewwhite

Isolation. Better use of hardware resources

Dennis Kaarsemaker

12:04

lxc/docker's isolation is a farce

ewwhite

@DennisKaarsemaker well, no.. it's not secure

Dennis Kaarsemaker

I'd rather go full virtualization if better hardware use were something I care about

Iain

My comment on the recent blog post got an answer - bets on how long it takes to get sorted ...

ewwhite

I'm doing this to avoid using single-host VMware installs for lightweight services

Dennis Kaarsemaker

@ewwhite why not simply put all services on the host?

Don't say isolation. 'cause docker doesn't give you that

ewwhite

12:08

@DennisKaarsemaker granular control, separate IP addresses

dawud

@DennisKaarsemaker There is s-virt capable docker

ewwhite

easier to use than raw cgroups

Dennis Kaarsemaker

@ewwhite granula how? And you can do multiple ip adresses per host you know :P

@dawud if that's as user friendly as selinux, nobody will use it

I still disable selinux everywhere

Iain

@DennisKaarsemaker I leave it on but have a check high on the list for it when debugging
