unit of fMEM in /proc/lve/list

[chris.webz]

I need to know whats the unit of integer number in column of fMEM while using `cat /proc/lve/list`
Its number of failed visits because of lake of memory or its the total memory which was required to not getting error 500 for those visits?

[iseletsk]

number of memory faults.

[tincboy]

Its a little strange number, because Ive sampled it with 5 minutes interval on a website which has less than 2 visits per minute, but in this intervals I can see the number is increasing by 5 to 50 counts,

[iseletsk]

1 visit can mean multiple processes started, and some processes can generate multiple memory faults.

[tincboy]

Do you have any benchmark regarding each famous web application like Joomla, Prestashop , etc memory usages?

[iseletsk]

No, we never did that. Plus, it depends on plugins, 32bit vs 64bit, modules compiled into php, usage of opcode cache, etc...

Ive an other related to `/proc/lve/list` question,
If I sample CPU column for an lve with interval of 60 seconds and then divide the subtract of these two samples by 60, will it give me the average usage of CPU in Hertz?

[iseletsk]

For lve version > 4 use (first digit in /proc/lve/list)
1000000000 * procs

where procs is the number of processors as in /proc/cpuinfo

for lve version <= 4:
add up all the: cpu mhz * 1024 * 1024 from /proc/cpuinfo

[tincboy]

Thanks for you explanation, but Ive trouble finding procs,
Its my cpuinfo, would you please let me know how many is my procs?

Procs is the total number of times processor field is in that file.

[tincboy]

Thanks again dear Igor for your fast response,
but I didn find out what you mentioned clearly.
Would you please specify exactly which row of that information you mean?

[iseletsk]

This one.

processor : 7
