Monitoring Server Performance
Aug 17, 2008
My dedicated server is sometimes sluggishly slow. I would like to get a grasp of its performance during a day, to get a better understanding of what's going on.
Therefore I am looking for a server performance monitoring service. All service I found so far were simply monitoring uptime (server is down / server is up). I need something more - a service that checks every 30 seconds or so the loading time of the main page.
Then it would allow me to download the data in CSV or draw a response time graph.

some software which would allow me to monitor critical information about my VPS and possibly give me graphs/charts that show me things like my system's load over time. Since it is a VPS I may want to see this charts/graphs via a web interface if I can't just download some rendered jpg's or somethin from the server on a regular basis.
So what I'm looking for is something kinda like the Bandwidth page under Web/FTP Stats in Cpanel so I can easily get a better idea over a few days or week(s) what times of the day my server is getting taxed and when load low.

I am using dreamhost host 3 of my web sites and 1 blog. Dreamhost is great, offers alot space and bandwidth.
but I think they are oversellling their space, sometimes it gets really slow. (overselling ? ok, I dont really know, but sometimes its really slow, and most my asian readers said need to refresh to load the page. I am wondering if theres a way to check if they are overselling or not.)
I am thinking about buying vps, even tho, I still got 5 month left with dreamhost.
I found 2 vps companies are highly recommanded on this forum, JaguarPC and LiquidWeb.
theres already a post compared both companies in terms of price and service. I say I will pick JagarPc, cuz, its basic plan just 20 USD, and htey got promotion now, its even cheaper. and basic Liquidweb vps plan is 60 bucks.
I am wondering why Jagarpc is so cheap , are they overselling? how can we check if they are overselling.
I found a few posts saying how good jaguarPc is. and they are not overselling, but those members just signed up this month, and only have 1-3 posts. I cannot really trust those new members.
Can someone share their experience with JaguarPC? compare JaguarPc performance and liquidweb performance. antoher question is switch from dreamhost to JaguarPC basic vPS plan, will performance gets better?
last question: VPS account allows 3 IP, 3ip = 3 domains? if not, how many domains can I have?

We are getting into VPS hosting and wanted to get some opinions and feedback as we're quite unsure on what to expect as for performance and how many clients we can generally keep on a box.
For now we've bought 3 dell R710 with dual Xeon L5520, 72GB ram and 8 x 2.5" SAS drives.
We are thinking of a base offering of 512 megabytes of ram and
was hoping to get about 40-50 onto a server.
With 40 there should be -plenty- free ram and plenty drivecache.
Then a next offering of 1 gig ram and next one of 2 gigs.
Even if we do the biggest 2 gig offering with 25 on a server we should have free ram to spare.
The software would be virtuozzo.
Any thoughts on this, am I expecting too much, or am I being fairly realistic?

Hi"Optimization of computing resources has long been an important management issue. One of its aspects concerns server scalability and the question of whether an organization should scale-up or scale out.Assume that the computing performance of the servers can be measured by variable 0 <=p, that their total cost is given by "c" and the relationship between server performance and cost is defined by c=αp^β"
a. What is the cost-performance elasticity(ђ), precisely?
b. What would be the range of values for ђ that would be expected by moore's law and what are its implications?
c. What would be the range of values for ђ that would lead managers to scale-out? Draw a graph and throughly explain the implications.

We are a web-based Yacht Charter company, with offices scattered around the world:
www.boatbookings.com
Currently, both our web site and our back-office business management system are hosted on a single server in the UK, with an automatic fail-over to a server in Dallas, TX, USA.
The problem we are having is that our sales office in Singapore is having really slow response times and this is very frustrating for them.
Using an application called "JustPing" we see that response times From Singapore are much slower than other parts of the world. (the cities closer to London are fastest, the ones further away are slowest)
JustPing Results
Is there anyway to improve this or is hosting our applications on multiple servers the only way to improve performance. What's the best cost-effective method of multiple server hosting?
(Incidentally, if I JutPing Google, response times are fantastic worldwide, but we know they're hosted on many, very large servers)

I was just playing around with litespeed and I thought I would switch back to apache for a few min to see how the server reacts. The load with litespeed was 1.00 - 3.00. I switched to apache the load jumped to 28.00 - 35.00. Its amazing how litespeed is handling connections.

Is there a site which will enable me to enter url of my website and it will simulate visitors from multiple locations. It needs to open the page completely, and run for example 10 minutes. Two things I found are host-tracker, but it just gets headers from multiple locations, and does it only once. Another thing is Paessler software which can test exactly what I want (number of visitors for some period of time with full page download) but it must be run from one (my) PC, so I can not test bandwidth from multiple locations. I need combination of these two, anyone knows for something like that on the net?

I've recently found (last 6 weeks) that the performance of my client's websites on my trusted host's servers isn't how it used to be and/or how it should be. The download seems to take way much longer than before. So far it hasn't resulted in a significant drop in average pageviews per unique visitor but it might do if things continue. The host claims a number of attacks on the mailserver and an unusually high load at one point in time. Above all it's just annoying - isn't reliable server performance what can be expected from a reputable host?
Here's the question: what's the best way of monitoring online how the web and mail servers are performing so that I can take this report to my host and urge them to take (more) action? Ideally I'd like to compare this with a seperate web server that I use for another client. I don't mind spending a little bit of money but high subscription fees are not in my budget.

My company has been having some issues with our email periodically but our host provides no help other than a graph showing the amount of daily relays.
Does anyone know of a good email server montior or diagnostic solution that works with MailEnable? Preferably something free or cheap.
I basically want to be able to get in and see what emails were sent and received from who and the IPs if possible. I don't care about seeing the content of peoples emails but just a report similar to a telephone bill would surely help.

I'm thinking of purchasing a server that will monitor about 50 different servers using Nagios. It would probably just run Apache and nothing else but i was wondering if anyone has experience setting up a Nagios server just for monitoring other boxes on a network.
I'm wondeirng if this can be done. I will be monitoring a few customer servers but would like to give those customers access to Nagios and access only to their servers and nobody elses. Is there a way to setup Nagios so certain users can view their own boxes and nobody elses? Probaby setting up some type of group configuration. What about alerts? If a customers box goes down they would need to be alerted. Does Nagios allow those users to receive alerts specific to their boxes.
Not even sure how powerful the server should be. Probably a Celery or something a bit more powerful should do.

how do you monitor the server CPU load?
Is there a script or package that you can recommend? I am looking at htop currently and want to know other alternative out there.
End of the day, I will like to have a stats that shows the sample of the server CPU load, maybe sampled over 5mins interval.

We currently have around 45 VPS clients and dedicated servers, We are looking for a script that can be seen from the internet but requires a login, It will notify us when a server goes down or a service goes down. It will also keep track of the Bandwidth usage, etc. We can set custom names and add servers to monitor.
Is there anything like this or a Big VPS hosting company is using?

I've got a VPS which is serving as the main server for a number of sites. Web Server, SSH Server, and Mail Server.
What I've got running:
Apache2, PHP5, MySQL5, Dovecot, Postfix
One of the sites is a growing forum with a MASSIVE photo album. This is the site where I notice the most slowness.
Changing the server software is not an option - Only optimization.

We have CentOS 4 and WHM 11 on server .
Now-a-days server is having too much load due to http and in access logs we see following message :
========================================
127.0.0.1 - - [11/Oct/2008:01:40:02 -0700] "OPTIONS * HTTP/1.0" 200 -
127.0.0.1 - - [11/Oct/2008:01:40:03 -0700] "OPTIONS * HTTP/1.0" 200 -
127.0.0.1 - - [11/Oct/2008:01:40:02 -0700] "OPTIONS * HTTP/1.0" 200 -=============================================
And due to this there is load on server. We are not able to understand why this is happening and how to stop this. So please suggest with some solution.
