System Performance Monitoring Package W/ Graphical Output
Apr 14, 2007
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 have dedicated server with cpanel/whm, Centos 5, today I got this error when I want to upgrade my Apache 2.0 to 2.2 I try to upgrading it and getting the flowing error. I have rebuild apache before 1 month and it was rebuild without any problem. Now I am getting this error.

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.
I am wondering if anyone knows of any good system monitors for Linux. I will be installing several web and database servers at a branch office and would like to receive stats like system temperature, cpu load, memory usage, etc. Basically something to tell to warn me in the event of a hardware error. I am looking something with an easy-to-use web interface and ability to generate reports.

Technical Support unable to know why the Monitoring System sending this eamil although SSH is working fine and told me to wait till monday so the monitoring group to work on
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?
# If a PT_LOAD event is triggered, then if the following contains the path to # a script, it will be run in a child process. For example, the script could # contain commands to terminate and restart httpd, php, exim, etc incase of # looping processes. The action script must have the execute bit an # interpreter (shebang) set
It's a feature of CSF, how to write a script that will output the contents of top -c to another file?
Problem is that the only way to stop this command is pressing CTRL + C, and i just need some option to specify how much time the tcpdump will be running, i need it running for 1 minute for example, and then it should automatically stop.
how do i get all the current dns values for a domain name? i have tried using 'dig domain any' and get varied results. the first time it is as if i ran 'dig domain a' I then run 'dig domain mx' and see the mx records. an issue of 'any' then shows the mx records so far i have to run dig with every record type. what is another way to get all the dns values for a domain name?
What command could I use to get the last line of an output?
Heres why...
I use this command:
netstat -plan|grep :80|awk {'print $5'}|cut -d: -f 1|sort|uniq -c|sort -nk 1 I would like to get just the last line of the output, the output looks like this:
The reason is because I'd like to get that last figure to place into a file on a certain time period (through a cron), which will then be graphed with PHP.
I use Munin to monitor the health of our servers, I can tell by looking at the graphs there's nothing to worry about, however, I'm struggling to baseline acceptable performance.what would be classed as 'normal' output for some of the more relevant munin graphs.
I've been looking at the Apache* modules and this is the output from one of our servers:
average of: 300 accesses per minute, 6 busy servers and 4.10MB a minute volume
max of: 1400 accesses per minute, 81 busy servers and 51MB a minute volume
This is a dedicated box running one site.
We have another box that is running approximately 30 sites
average of: 30 accesses per minute, 1 busy server and a 500K a minute volume
max of: 322 accesses per minute, 11 busy servers and a 4MB a minute volume.
These servers are pretty much the same spec, dual core 64Bit, 4GB of ram, two SATA disks in RAID1.
I am using Apache 2.4.1 (Win64), PHP 5.3.10 on Microsoft Windows 2008 server. I have also installed Microsoft VC++ 2010 (64 bit). I successfully configured mod_fcgid 2.3.7 as per the instructions. This was confirmed by running info php page. But when I run FastCGI test scripts, the output is displayed in text form and not in html format.
I have an apache server on windows which I wanted to speed up using caching systems.
I tried installing squid, and I got it working with a basic example config. It seemed to work well, however under more heavy load I experienced some weird behaviour where network output is 0 for several seconds at the time, and all clients just hang in the wind and wait for a respons.
Remote to the server is working fine, so it's definitely a squid issue.. with only apache running the server is constantly sending out data, no halts there.
for over a year now, with iptables. However recently, after upgrading to apache 2.2, the connections in netstat get listed as ipv6. A row can look like this for example:
As you can see, the remote ip address isn't complete, it's cut off, so the script used to sum up connections and insert into iptables isnt doing anything.
We have a plesk server running on a Ubuntu 14.04.2 LTS machine. We check the state of the mailqueue with nagios, executing the "mailq" command. After the AutoInstaller upgraded our installation from 12.0.18 update 38 to 39, we noticed, that the nagios check failed.
After investigating a little bit, it seems that we found the problem:
When I enter "mailq" in the shell, the command is executed and gives me an proper output. But when I try to execute the command with its full path "/usr/bin/mailq" nothing happens, and I have to cancel with [ctrl]+[c]. The which-command delivers exactly the same path as written above...
