One of the projects I will work on will require to process 50,000 emails a day. Most of these emails would include attachments and the challenge is to process them and put all the stuff into a database for the application to use.
My biggest concern is spam and we cannot afford to lose out on legitimate emails. One way of configuring the setup would entail checking emails for the specific types of attachments and piping it in.
However I was just wondering if someone here has dealt with this volume of emails and also what are the spam limiting options available (even commercial would do)
Is it possible to query for a list of system users using the API RPC? I know it's possible with a MySQL query
Code: select id, login, account_id from sys_users order by login;
I've searched through the API RPC manual, but I don't see a way to do this. I always have to specify a filter, I can't find a way to just query for all users.
I got 5 wordpress and 5 statics website on this server and 100 visitors by 24H00 each day.
Question 1 : Why the memory is so low and the swap so high ? Question 2 : Why i don't find high usage process in top command ? Question 3 How can i resolve this problem ?
I have a site that is eating up my server resources and need to know what the best solution for this is. I'm thinking of getting another server just for mysql but do not know what specs the server should be to handle the current traffic/database load and have the site run smoothly without slowing down to a snail's pace.
An alternative is to get another server just for the videos being served and leave the database and html on the current server. This is where I'm stuck and don't know what route to take with this.
I've attached screenshots of top and bandwidth usage per day. Hopefully with this information you could tell me if I need another server or if there are any things I can do to the current server to help things move faster.
I own a small company of 15 people who are all based remotely at their own homes throughout Europe.
Most of us are based in the UK and our web hosting server names.co.uk provide our email and web hosting service but we do not have an exchange server with them.
Now most of my colleagues own blackberry's which i just dont get on well with and I have my eyes set on buying a windows mobile device with Push email, namely the Sony Ericsson Xperia X1.
Anyway my query is this:
How do i go about getting exchange included to my hosting setup? Can another company host it or do i have to transfer my web hosting and email hosting to another company which facilitates exchange as well?
I have noticed a weird thing lately with two VPS accounts. Virtuozzo's system usage meter on the Resources page creeps up to 100% over the course of 24 hours or so and stays there, but stays green and I don't get any QoS alerts. The servers both seem to be running fine, and I haven't had any crashes. One VPS is running a few Wordpress blogs.
The other is running some Joomla sites.
Both are running Virtuozzo on CentOS 4.7 i686 with WHM 11.24.2 and cPanel 11.24.4-R32486.
In the past, when the system usage meter in Virtuozzo got anywhere near 100%, it turned yellow or red, I had sites go down, and all kinds of QoS alerts for privmpages were thrown. It turned out back then that I had a bad PHP script eating tons of memory with too many MySQL queries. That doesn't appear to be the case here, since I'm not having any apparent problems with either server. It seems like a "non-problem" but it has me concerned because I'm used to using that system usage meter in Virtuozzo to keep an eye on the health of the VPS..
When I look at memory used in WHM (WHM->Server Status->Server Status) it shows only 31% used, which is what I used to see in Virtuozzo.
When I run free, I get:
root@server [~]# free total used free shared buffers cached Mem: 524288 133804 390484 0 0 0 -/+ buffers/cache: 133804 390484 Swap: 0 0 0 When I run Free, I get: root@server [~]# Free Memory limit...: 8388604 MB (burstable: 8388604 MB) Current usage..: 120 MB (0%) (requested: 264 MB) Free memory....: 8388484 MB (100%)
Initially, I suspected it was another problem with MySQL, and restarting MySQL does drop the system usage meter down to ~31% in Virtuozzo for a while--without changing the actual memory used on the System Processes page--but the memory usage for MySQL with Virtuozzo pegged is only 6.23% in WHM.
Here's the really weird thing: If I look at Virtuozzo->System Processes it shows only 0.4% (I think they mean 40%) of total memory used, half of which is mysqld and the rest is spamd.
With no sign of problems, it looks like Virtuozzo is incorrectly reporting memory usage in the system usage meter, but correctly in the system processes list.
The web host's response was:
We use SLM for managing VPSes. This enforces your per VPS limits and doesn't let your VPS use more then it should be. It sounds like you guys may have some memory hogs in your applications.
Have you guys considered cutting down some of the unneeded plugins and stuff?
That doesn't make any sense to me given the disparity between the memory usage meter and the amount of memory usage reported in System Processes and with free/Free as well as the lack of QoS alerts, but maybe SLM prevents any alerts? I don't want to let a memory hog run free on my system if one exists.
I have server with P4 ( 2.4ghz) 2gb ram with cpanel and centos.
When I get more than 300 users online on my forum. Server load remains under 2 but Ram usage get's high upto 90% every 10 to 3 minutes. I have to restart apache in order to keep it down.
Am using Hypervm,my all vms are not using more than 512 MB memory but when i click on server as localhost the there is show maximum memory usage I have total 8 GB it always show 5-6 GB usage and never drop down, How can I fix this matters?
i have a quad core Intel XEON 5130 @ 1.60GHz . with 6giga now of memory . i have about 300 account in it . CENTOS Enterprise 4.6 installed .
the probleme is that the memory server it used in totaly . after i was just 2Gb of ram , but sometimes the server lod arrive at 50% . for that i have added more memory (4Gb) , when i added it the memroy usage is always about 4giga sometimes about 3980Mb . the load is normal , but sometimes the server loas arrive at 50% or 60% (this is just in specific times) . after i have decided to add 2 Gb more , now is 6gb in the server . but also all the 6giag of ram is used , the load is normal but memory is all used , look to the top command
now iam haveing more that 0.50-1.20 cpu useage,also cpu useage is also increased i hosted only 6 site out what only one site use MSQL all other site are plain download site,how to reduce the cpu load can u figure me out this issue also give me some tips to reduce the cpu usage
I noticed high cpu usage on my server since a couple of days ago. I neither updated software nor changed the configurations on the server. The server load was about 0.5 ~ 1.0 but now the average CPU load does not go below 5.0
when I stop apache (1.3) the load goes down and as soon as I start it up the load start increasing.
I checked for DoS but it seems nothing exists of this type.
I tried to follow the access_log file but from the first view nothing is strange there.
I don't have any control panel on the server. just Apache, FTP and SSH installed.
Since yesterday named started to use more cpu than usual. Techs "refuse" to work with that issue and saying that its's normal. Though all the time had no problems, haven't added hundreds of domains yesterday and there were no changes from my end.
There was one change from techs side however.
"the MX record for the domain was going to localhost, rather than the domain name. I have changed the MX record to domain..."
Anything I should check? Logs doesn't provide anything valuable, just notices.
I am running a youtube clone on a VPS with 512mb ram at Lunarpages.
Whenever I log into Plesk, I find that my system usage is extremely high. 90%++ even up to 100%. However my CPU usage is often less than 5%.
This problem often occurs when there is slightly more visitors on my site. I am talking about only 30++ visitors and this problem will occur and my site slows to a crawl and I have to restart the VPS.
i have a problem with my server it is a Xeon with 2Gb ram, i have a igh swap usage and when it reach the size of 4gb that i have set it go in kernel panic, this is the actual value
I need some help my CPU (Intel Core 2 Duo 1.7 Ghz) always gets high usage from mysql sometimes its using 95% cpu etc... How can I modify my.cnf to use less CPU and more ram since I have 3gb ram installed?
I purchased a VPS at wiredtree to upload a site that is in the works so that it would be "ready" once it was launched (had it sitting on a shared server before). So I have this domain on there, as well as a small wordpress blog. In total I'm get a very miniscule trickle of visitors to these websites (as they are not officially launched), around 100 visits per day, many of which are only 1 pageview visits.
My problem is, my server is already idling over its memory limit of 256mb. This is causing major slowdowns, and processes like cpanel are constantly be killed and I can't login.
Does anyone have any idea what is causing my high memory usage? I just can't image that the visitors I am getting are doing much, as for the majority of the day I have absolutely no one viewing my domains, yet my memory usage is still over the limit.
Wiredtree support says its up to me to optimize my msql/php scripts etc for low mem usage, but I don't see how this will help when there is no one using them in the first place.
For some reason cpanellogd always had huge memory usage in the realm of 40-90% when running logs for one particular site, which inturn sends the server load to 25-40.
What can cause this? I have delete logs after stats run enabled and all the usuall.
I was wondering is someone can shed some light on a curious situation for me. I am running a linux server (Gentoo) and the CPU usage spikes to 90-100% but the load of the server when viewed by top is only 0.4 - 1.5 (max). The memory is OK with .5 gig free and there is no paging going on. So my question is: Is this server over used or not?
Below is the output of top 3 times over aprox 2 min... please enlighten me... :-)
just noticed mysql cpu usage has shot up from its usual 5-10% cpu to 30%+. domains are as normal and no extraordinary php processes.
any way i can tell what users are most heavily running mysql? (as in number queries / slow queries etc?) i know mysqladmin processlist but that only gives me a snapshot, whereas i want to see over 24 hours, who used mysql the most...
a few times, my host contacted me and said that my account is suspended due to high usage of server resources.
I have 3 sites using SMF (a forum script.) I have around 8500 visitors and 3 million page views per month in total.
can this be a reason of high usage?
if it's what's the meaning of terabyte traffic limit ? which you can never use
I asked to my host if they could let me know what's causing high server resources usage. here is the answer:
We do not know which domain or script caused this high usage, it is your responsibility to investigate. I would suggest that you go through your raw access logs to see the most requested pages and then investigate those further. After you find the pages responsible, please optimize them so you are not using so many server resources.
so if a host wants simply to restrict traffic limit, they have a pre-reason under hand.high server usage! yes but how will I know that? how will I trust that it's true?
when I ask why my sites are down, they can easily tell me that it's because of high server usage!
