Hello,
I have some spare rack servers and I want to setup my own Monitoring server. It can be either windows or linux.
Ideally I want to be able to:
Create Groups ie Group1/company 1 and list the servers. Have a webpage to Group1 that shows the current status.
Any changes can Email selected users of group1 and ideally have some kind of SMS gateway that can send SMS Alerts.
Free is good but I don't mind paying for the application but i dont want an expensive application. We will be monitoring around 50 servers.

Nagios sounds perfect for what you are looking for :)

As of Zabbix 1.6.2 you can create specific user groups that receive email alerts for hosts also. http://zabbix.com/. Zabbix takes a bit of reading to get it installed and configured properly.

Do you know of any tutorials on how to set up Nagios on a linux ubuntu server? Also, do you need to run Nagios on the same server as it monitors?
Thanks.

Nagios isn't hard to install but it is hard to configure.. it involved editing config files to add servers, services, contacts, etc.
You should start with their quick start guide.. http://nagios.sourceforge.net/docs/3_0/quickstart.html
It monitors services such as http, pop3, imap, dns, etc remotely.. I think there is an agent to monitor load and disk space also, but you don't normally have to install anything on the servers you are monitoring for checking of web services.

Hi
After I opened this post I come across Nagios and installed it, I have not configured it yet.

Don't worry about what is said about configuring would be hard; any monitoring software will be hard to configure; if not; it is to simplistic for real use; a monitoring tool should do more as just check if a port is open/responding, it should also look at trends and being able to consolidate alarm messages to one message (i.e. a network component fails; you do not want to see all alarm messages from your server park telling that the servers are unreachable; you already know, but you would want to see other server errors like a harddisk failure).
Monitoring at its basic level can be done by many payed services; which often offer you great remote monitoring, it is costly to build this yourself; but real enterprise monitoring goes much further. Nagios gives you a good free tool to make a start. Other tools which would be good to use (but are rather expensive) are i.e. Tivoli, CA TNG, HP Openview, BMC Patrol or MOM.

IPmonitor from Solarwinds is easy to install and easy to configure and also very powerful :)

Is IPmonitor commercial or open source?

its commercial, maybe a bit expensive too. Depends on how you look at it, but you get what you pay for.
We have 6 different servers running ipmonitor and are very happy :)

Hello,
I will suggest
For Linux: Nagios
For Windows: OPManager
You can also check the software whatsup from ipswitch

Sorry if im hijacking just seems silly opening a new thread when this ones active,

Thanks

I noticed you're using WHMCS. Did you know WHMCS has it's own server monitor under Utilities -> Addon Modules? Take a look and it might be what you're looking for. :)

Thank you jon nifty little secret there exactly what im looking for

Hi,
There is a CD version of nagios all ready to go with many addon's and extra's to make nagios easy to configure and install.
See http://sourceforge.net/projects/fannagioscd
We used this after finding it hard to configure Nagios.

You are probably looking something like StatusMon

I have whmcs and when I go to utilities addons, all I have is ip monitor. Is that what you're referring to or is there another module available for 3.8?

There are two particular products that I can suggest, one of which I personally use extensively:
GroundWorks Open Source (groundworkopensource.com) which is based on the Nagios framework but has a number of very useful plugin's and third party integrations into one very useful and stable package. Highly recommend this.
Also, there is Hyperic HQ which is relatively good but not quite as extensive as Groundworks.
Certainly worth looking at as a Nagios alternative.

Yes my vote too go to the Nagios it is the best solution for your problem. Please refers to the link given below it may help you to install and configure the Nagios.
