Thread: Server Load

    * Server Load

    Hi all WHT members,

    I have a vps server. and I'm currently hosting around 20 websites. the most active one of them has 200 visitors/day. In the last couple of days I noticed that my server cpu usage is getting higher than normal (the normal was 0.0 to 0.5) but now it gets around 5.00 and I gett warning messages from ifd (High 5 minute load average alert). I ran the command top -b -i -n 20 >> /top_procs. but I can't see the one whos causing the issue. here are the results.

    Well you didn't allow enough lines in the output to be able to see anything useful. Any particular reason you didn't just run "top" and then watch to see who was abusing?

    That's "load", not CPU usage. "Load" is the number of active processes; on a system where the critical limit is I/O, load can go high even though the CPU is idle most of the time.

    See the example below from your list of results ... load of 5, even though the CPU is idle 62% of the time, and half the memory is free. But at times there were 8 running processes, which is why load was higher.

    Can you find out if it's only your VPS affected or other VPS systems on the same server?

    Looks like it is being caused by some PHP scripts. It's not 100% clear from the details you provided but during the times of high load User: shnelerc seems to be generating above average CPU.

    I would investigate that site and see if any of the PHP scripts they are using are running inefficiently.

    The command I used is "top". its just tell TOP to run in "batch" mode (not look for any user input), show only running processes, loop 20 times, and append the output to the file /top_procs

    Yeah, however you're trimming the output too much so it's not really providing anything useful.

    Change -n 20 to something like -n 25~30.

    D'oh, I must be out of it today - I've just never seen a TOP report only showing the top few lines, usually Linux servers are going to have a few dozen processes. Did you trim some of the results out? (I was thinking something like head -n 20 instead of how -n applies to a batch top) sorry

    I guess that's the "-i" parameter ignoring idle processes ... so the httpd process is not showing most of the time.

    Looking again, when load is higher, then the memory used is around 700mb

    So: what is the memory setup on the VPS? Does it have 700mb or more of dedicated RAM?

    And what's using the 700MB? It's not the processes listed by "top", so it must be idle processes. Is the memory use a result of httpd settings? Maybe there's a keepalive setting set to a longish value, which is causing idle process to occupy RAM.

    I'd run top again and have it include idle processes to see what their memory consumption is. Then see if I could modify httpd settings to reduce the number of idle processes, with the aim of reducing the peak memory usage to below the dedicated RAM of the VPS.

    My memory setup is 768 MB Guaranteed (1.5 GB Burst RAM).
    Yes the command I used ignores idle processes.

    Number of newly created process can significantly change the CPU load. CPU load parameter itself a "vulnerable" way to understand your cpu usage from my sense. Although, for your situation, you should probably talk with your VPS provider to check the load, it seems pretty unusual to me.

    Can you find out if it's only your VPS affected or other VPS systems on the same server?
    I would probably ask the same question. You should try checking if your provider is running some sort of container backups, that can significantly change the CPU load parameter.
