Server :: How To Monitor All Webapplications
Dec 21, 2010
I have a doubt in monitoring all my web applications.Actuallyhave about 20 web applications hosted through tomcat in our server.How to monitor all those applications at a time,whether it is up or not . Do we have any options in operating system itself for monitoring using logs.Because all those applications were accessed by clients and we should intimate the client first about outage in case of any problem in accessing our web application.

I would like to monitor a RedHat via snmp. I would like to make available data via snmp. The data that I would like to graph are only present in logs file. Is it possible to parse data from applicative logs and have them available for my cacti server via snmp? I already monitor CPU, mem, and others with cacti using the standard MIB.What would be the logical step I would need to achieve that?

I hope the server forum is the best match for my post, otherwise please redirect me.
I have a Fedora 12 Desktop machine running at a remote site and have no keyboard not a screen connected to it. After rebooting it remotely I was surprised to learn the machine did not come back up again. (It did when I tested it while I was on site).

Let's say I have a machine exporting 3 paths via NFS.
Code:
/exports/foo
/exports/bar
/exports/bla
I would like to know if there is a way to determine how many clients have each export mounted at any given time. I don't necessarily need to identify which client has mounted what, just the number.
Code:
/exports/foo is mounted by 3 clients
/exports/bar is mounted by 1 client
/exports/bla is mounted by 0 clients

I'm trying to get a remote viewer / VNC on a PC without a monitor. The default one that comes with it seems it wont work without a monitor attached (including that every time I connect, it asks me to enter the keyring password). Is there a way to get VNC server installed that it will mirror my desktop?

It will be quite literally bare, consisting of motherboard http://www.axiontech.com/prdt.php?item=88615, CPU, RAM, power supply only (won't even have case). I'm working as contractor at 3M and would like to reduce my baggage when I move.I will probably boot Debian on USB flash and access the machine with SSH, but my main dilemma will be how to setup the system while trying to avoid buying a keyboard and monitor. I can test the USB boot on my laptop, but I will need a way to diagnose problems. Beeping the speaker so I know the system is at a certain state would be a clumsy solution, assuming the motherboard even has a speaker.

when the server is getting overloaded with users. At present I run the server mainly as a proxy server with about 100 users. The bandwidth at the data centre is 100Mbps connection with total bandwidth used last month = 17431.16 MB
I would like to add a VPN in future but feel that this might overload the bandwidth as instead of it just being web traffic it will the entire client TCP connections. I would like to monitor this before it gets to the stage where users are complaining but not sure how to gauge whether the proxy is being overloaded. It is used mainly for video traffic.

Is there any way to monitor ambient temperature over the net?
For example I want to put one thermometer in the front of the cabinet (cold isle) and one in the back (hot isle) and monitor them over the internet, or have them report to a linux box.
What is the best way to do that?

I just upgraded to Ubuntu 10.04 yesterday on a headless home server. I use the server for a variety of purposes, and what I don't know how to do via SSH I've alway been able to do through VNC. However, since the upgrade vino-server will no longer run if there isn't a monitor attached. Before it used to start up without a problem. Even by attempting to run the server via SSH gives me a "could not load display" error. Summary: I need to get vino-server running at boot time on a server with Ubuntu 10.04, without a monitor attached.

I have been using Postfix since 2006 with no problems ever. Simple & rock solid however I was wondering what you guys use for monitoring all your email traffic and logs? Is there an application or utility you guys suggest using as a mail administrator to easily scan / view logs in a organized and clean view?

I wanted to know is there any way to monitor (I mean log)all of the activity of the users that logging in a server (as root) for example:
1.when do they logging in
2.what commands do they use at what time ( I know that history command do somehow the same but it does not save all of the activity of users exactly with the time of that activity)
3.which one of them installed which package on the server
4.what did they copy or move at what time and summery all the activity that each of them do on the server individually.

When you need to change something on the server you can hook up a monitor and a keyboard and do it through the console.
I would like to hook up an external monitor in this fashion for a desktop. The current video card can only support a single display. So I was hoping there was someway to use a second monitor as just a permanent console since simple text shouldn't require a video card?

I've got a headless server (32 bit 9.04/9.10, can't remember) that started refusing SSH and HTTP connections a few days ago, and I'm just getting around to hopefully fixing it. The problem is that I can't even connect to the darn thing. I've plugged in a mouse, keyboard, and monitor, but the monitor tells me that it has no signal. I know the monitor works with the computer, as I used the same one to set up the server.
Just for kicks, I even tried to put in a live CD, but that didn't help. Any ideas on how I can connect to this thing?

I have developed a website. Now i would like to monitor the IP address of machines who are accessing the server. The simplest possible solution to this that comes first into my mind is to use jsp inbuilt tags.
Code:
<%
out.print( request.getRemoteAddr() );
out.print( request.getRemoteHost() );
%>
but it has given me some other IP address(May be a proxy server's ip address)
So i was left with one choice is to run netstat on host server . Here is what i have done.
Code:
netstat -an | grep 8080 (As tomcat runs on port 8080).
Should i modify the command or there is any other way around to monitor the IP address?

We have a quad core Intel Xeon E 5410 processor running on recently installed centOS 5.5. Machine can't be pinged all of sudden and when we switch on the monitor, no signal on it, even no response on keyboard. We thought the problem accorded with abrupt temperature changes, is it so? But we have similar machines running efficiently under same temperature conditions.

We recently had an issue with "cat /proc/mount" telling us that a CIFS file system was mounted, even though the mount was not working correctly. So we're not sure if we can trust linux to report malfunctioning mounts, so we're planning on adding a specific file on the mounted file system, and verify the mount by reading this file from the client side (linux). If linux fails to read it, we know that the mount have failed. But before we go ahead doing this I thought I'd just hear how others are doing this sort of thing - how do you make sure that mount points are up and working?

EDIT: I just saw that I've posted in the security area, not in the server area. How do I move it?
