which server / network monitoring tools do you guys suggest or using?

I am looking for one that provides accurate information and also should have option to display information for anonymous users.

I don't know what your asking for exactly but for uptime and such like that I use http://Pingdom.com

There is also Siteuptime.com and basicstate.com which also gives you information on uptime and downtime if any.

We utalise status2k .. it provides a nice display for users and allows for live statistic images to be shown remotly, We've used it for nearly two years now and its yet to let us down

demo: http://www.status2k.com/demo/

I also found http://www.platinumservermanagement.com/index.html that someone told me about and it looks promising.

PSM is not a monitoring tool, they're a management company.

You can use Nagios which is pretty much the industry standard when it comes to monitoring servers. Although why you would want to make that information available to the public I'm not sure. The less information you can display to a hacker, the better off you are. You can always PDF a section of the reports to provide a potential customer etc, but I'd not provide live data publicly with no checks.

Status2k is nice too, I've used that in the past.

If you look at the bottom of the page, They offer server monitoring and details to your email for $10 a month.

we don't want to display complete information to user only the server uptime / network uptime. Rest is for our Audit.

Thanks for pointing that out - very interesting. It used to be that you had to have the management through them in order for the monitoring.

I stand corrected!

I recommend the network overview rather than any individual server information. We have a number of servers here that are going on 800+ days without a reboot, and then we have servers that are going on 6+ hours since their last reboot (actually, new servers going online). The data can be really skewed when a user is looking at the information and people may get the impression that the machine was actually crashed and rebooted 6 hours ago.

I'd recommend putting up a network overview or something similar to this rather than showing any individual server uptime status information.

Also the uptime reports from www.webhostingstuff.com/uptime are pretty helpful too. You'd have to pay to have multiple servers monitored, but it's at least something available to the general public to view.

I'm using http://host-tracker.com/ for years now. There is a 30 Day trial offer.

http://phpsysinfo.sourceforge.net/ is simple and fast
http://oss.oetiker.ch/mrtg/ is very useful for network monitoring

For network monitoring Nagios is really good. Website, hm, pingdom I think

Yes Nagios is very good.It gives a lot of statistics and information.

You could also try nagios,it is a quite good monitoring tools .

I use siteuptime.com , it sends alerts to my mobile phone.
