    Hey,

    I am not very experienced in administrating a server, so please bear with me.

    My site slowed down for some days now and I cannot figure out what the problem is.

    When I reload pages it takes quite some time till it reacts or sometimes the page is there but the images/avatars load after several seconds, specially threads with images. This happens sporadically, not consistently.

    I contacted the host and they said all is fine from their side.

    From my side I see that the average CPU usage is ~1%, Memory has half free, and I don't have much users online at all.

    Using webpagetest it gives me great results except for first byte delivery time.

    Is there any logs I can check what might be the issue here?

    I am using Cloudflare as a DNS and I suspect that might be the problem. I don't know.

    Thanks.

    If running Centmin Mod 123.09beta01 or higher, you will have access to a cminfo top command which can also provide a summary of statistics - some of which are explained in info and linked articles below. Monitoring server stats is key - logs won't show much unless it's MySQL slow queries which you need to look up how to enable/disable mysql slow query logging and then look up how to interpret the mysql slow query logs, run mysql explain and then understand how to optimise your mysql queries in your web app. All outside of Centmin Mod provided as is support unfortunately.

    FYI, CPU load optimal is 1.0 per cpu thread so 8 cpu thread normal = 8x1 = 8.0. 16 cpu server normal is 16x1 = 16.0

    so cpu load of 8 for
    • 2 cpu server = 8/2 = 4.0 load average
    • 4 cpu server = 8/4 = 2.0 load average
    • 8 cpu server = 8/8 = 1.0 load average
    When you type top command, hit number 1 to break down per cpu stats

    Centmin Mod is provided as is, so troubleshooting load issues is left to end user to do. However, there's many linux tools and scripts that can help you figure out what was causing the load issues and when.

    If you're providing info on this forum, more info might be helpful
    1. What version of Centmin Mod ? .08 stable or .09 beta ? If .09 beta when was it installed and when was last time you updated ?
    2. What's your VPS/Server hardware specifications ? cpu type ? memory available ? disk space ?
    3. Who's your web host ? Different hosts have different limits for server resource usage and some are more restrictive that others so it could just be their resource usage policy you tripped which may or may not be restrictive. If restrictive, then real solution would be finding a better web host. If not restrictive, then it's finding out what caused high cpu load.
    4. If running Centmin Mod 123.09beta01 or higher, you will have access to a cminfo top command which can also provide a summary of statistics - some of which are explained in info and linked articles below.
    Tools and commands you will want to read up on and learn for basic system admin tasks and troubleshooting.
    Notes:
    For example what's output for these commands
    Code (Text):
    top -bn1
    

    Code (Text):
    ps aufxw
    

    Code (Text):
    sar -q
    

    Code (Text):
    sar -r
    

    Code (Text):
    sar -q -f /var/log/sa/sa$(date +%d -d yesterday)
    

    Code (Text):
    sar -r -f /var/log/sa/sa$(date +%d -d yesterday)
    

    If you want to look at per process usage stats use pidstat run pidstat every 1 sec for 5 runs and sed is just to replace your main hostname with word hostname so mask your domain for posting on public places
    Code (Text):
    pidstat -durh 1 5 | sed -e "s|$(hostname)|hostname|g"
    

    for posting code you might want to use CODE tags for code How to use forum BBCODE code tags :)

    If you're a Centmin Mod Premium Members you'd also have access to custom Google Analytics dashboards to leverage GA page speed tracking to be able to break down your page load speeds by visitor/country/city/browser etc. Examples at https://community.centminmod.com/threads/premium-user-membership-explained.1080/#post-5068

    Thanks, that is actually a great response. It will take some time to go through everything, but I will go through it and respond to your questions. This is a great start, much appreciated as always.

    Btw. I know that this kind of help is outside of CMM. I mean this is basically a hired position, which is why people go with managed solutions like shared hosting or a managed VPS/Dedi. But as I go with an unmanaged VPS, I have to do it by myself, which is fine. I just need some tips and tricks, and thanksfully you provided those, that is all I am asking for.

    For starters here are the logs I managed to get so far. I'll split them into several posts probably because of the length. I think cminfo answers your 4 questions, so I won't answer them seperately. But I can say that I am running the latest CMM, updated 2 days ago.

    looks like 1 cpu core isn't enough for your requirements

    I thought that would have been obvious, but I should have stated it. As the time indicates, that is night time where the server backup process kicks in, where also the board is automatically closed. Backup takes 10 minutes max.
    So that is not a problem.

    Particular time of day is sporadic. For example today morning UTC 0 between 8-11 AM it was slow or some hours ago. The site feels slow and doesn't feel snappy. Images load afterwards or threads too.

    I suspect it could also be a CDN issue as I use Cloudflare as dns. But other users who live UTC 3 hours away have also same issues.

    What does it mean and for what time is this? The log states
    Code:
    [28-Jul-2019 14:35:07] WARNING: [pool www] server reached max_children setting (8), consider raising it
    So I guess I have to increase it, what would you suggest?

    Type:
    Code (Text):
    fpmconf


    and post the output, in particular these parameters:

    Code (Text):
    pm = dynamic
    pm.max_children = 50
    ; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2
    pm.start_servers = 15
    pm.min_spare_servers = 10
    pm.max_spare_servers = 20
    pm.max_requests = 400
    


    The behavior is very consistent with php issues and the log error indicates the same. The good news is that it is easily fixable as you say you have some spare resources left.

    I was about to write a post about this just right now and was entering my values, and you just wrote. Nice coincidence. Anyway:

    To document my progress and to have a reference point if sth. goes wrong, this is my current setup (default what CMM provided, haven't touched it so far).

    usr/local/etc/php-fpm.conf

    Current

    Code (Text):
    pm = ondemand
    pm.max_children = 8
    ; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2
    pm.start_servers = 1
    pm.min_spare_servers = 1
    pm.max_spare_servers = 3
    pm.max_requests = 500


    After reading this, I thought I should change them by that calculation, what would you suggest?

    So total memory for me is 2048 MB.

    The output for
    Code (Text):
    [17:55]# ps -ylC php-fpm --sort:rss
    S   UID   PID  PPID  C PRI  NI   RSS    SZ WCHAN  TTY          TIME CMD
    S     0 21980     1  0  70 -10  8172 162883 ep_pol ?       00:00:03 php-fpm
    S  1000 27563 21980  0  70 -10 31712 164707 sk_wai ?       00:00:00 php-fpm

    So according to that article 2048/32MB = 64.

    I thought I should give it a breathing room, so maybe 32 is a good number?
    But I wasn't sure about the other numbers. Seeing the numbers in the article and seeing your example, I thought 5 is an okay number? Which would be then this:

    Code (Text):
    pm = ondemand
    pm.max_children = 32
    ; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2
    pm.start_servers = 5
    pm.min_spare_servers = 5
    pm.max_spare_servers = 10
    pm.max_requests = 500

    Disclaimer: I am just a regular noob, I am more or less similar to you - when I encounter a problem I learn by reading and doing :) So don't take my advises as some pro opinion, I do want to help based on the fact that I had php issues twice, so I spent a bit of time reading about them, but in the end I am not a pro so I do hope I am not misleading you.

    I noticed earlier that your load is kinda light, 3k requests for 10k seconds uptime. Is that your typical load or that was during night time as mentioned earlier? It would be nice if you can get fpmstats from longer period preferably covering peak load as well.

    Starting from top, I would rather switch from ondemand to dynamic.

    Ondemand = php workers are started only when needed, this is good for very low traffic websites or when the server is mainly used for different purposes, but otherwise it introduces additional lag and latency.

    Dynamic = the amount of php processes will scale with demand, but you will always have few resident processes ready to kick in as soon as required. More physical resources are required, but the lag is reduced. As you mentioned that resources are not a problem, I would go for dynamic.

    Max children = the absolute ceiling of allowed started php processes. While you should definitely increase it from 8 (since you are getting max children reached error in the php logs) I think with your load 32 is overkill and becides I am not sure that each process will consistently take 32mb. You definitely don't want to bring your entire server to its knees. 20 I think should be enough for now.

    min/max spare servers - the minimum/maximum number of processes that should stay idle waiting for requests once they are spawned. You do want to have some available to pick up sudden rush of traffic, but you don't want too many as they will just waste your ram. I think 5 and 10 are more then generous values for your amount of traffic.

    start servers - calculated based on the commented out formula, in general should be somewhere between min and max spare servers. Lets say 8. With your current suggestion you will always have exactly 5 running processes - no more, no less.

    max requests = 500. I think this is mostly fine, you might even reduce it to 200-300. This is the amount of requests each process will take before killing itself and respawning if needed. You don't want your processes clogged by memory leaks, but you also don't want them constantly respawning.

    So I would start from here:

    Code (Text):
    pm = dynamic
    pm.max_children = 20
    ; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2
    pm.start_servers = 8
    pm.min_spare_servers = 5
    pm.max_spare_servers = 10
    pm.max_requests = 300
    


    I am not sure if all parameters are needed when using pm = dynamic, but having them set won't hurt for sure.

    Monitor it for a few hours and check fpmstats after that. Especially the max children reached parameter.

    By the way, very realistic possibility is that some aggressive bot or scraper is going through your website - those can waste all available php processes through thousand simultaneous requests, you should be definitely do something to stop bad bots (if you haven't already), but lets see first if tweaking the settings will help.

    We all started somewhere and any help is appreciated, so thank you. Thanks for the disclaimer, but I don't think in this case much could go wrong and if so, one can revert it easily. So all should be good.

    Yep, that is typical for me. I am in a very small niche, I serve professional people mostly.
    And as said before, the heavy load during night time is the backup process kicking in. I am taking daily backups of the server at night time and it takes roughly 5 minutes (max 10) to create a backup. At that time the server works with 100% for 5 minutes when all people are sleeping and when the board is closed anyway. So that one is not a problem. My problem was during daytime where the site took so many seconds to load. As you say my load is light, usually for the past year my server response time was lightning fast. Instantly loading pages and images. Right now for a week or so it slowed down. For a few hours it is instant again, then for an hour slow again. I thought maybe I should ask my host to switch me to another node if possible.

    How to get fpmstarts from a longer period?

    Can you tell me what to monitor exactly and how to monitor it?

    Okay, I changed all numbers according to your suggestions. I'll update you guys later about it, positive or negative. Thank you.

    Just keep the php on for several hours without restarting :)

    A quick update:

    Site is snappy again and everything loads instantly again. It is a very noticable difference right now. It is even better than it was 1 week ago before all the problems started.

    Thank you all!
