I actually prefer to backup a MySQL slave because you can very easily tell it to stop replication and then do a snapshot or mysqldump while it is not replicating. You get a simple point in time snapshot of your database system. Once the backup is done tell the slave to start replication again. This assumes that your master database isn't over loaded trying to replicate data to slaves as the now out of date slave is going to need a lot of data to get caught up.
1) Free but offers paid support if you need it 2) Can use agents, snmp or simple checks like ping 3) Agents can be extended with your own scripts and such. If a check isn't built in you can add it. For example, I added a very simple script for checking of MySQL replication had stopped or failed. 4) Templates, makes it easy to add a metric and create a trigger based on that metric to any host attached to that template 5) Triggers can be configured to minimize false positives (multiple dropped packets before sending an alert. 6) You can graph item, group of items or an aggregate value of items in a host group 7) Create your own maps 8) Create custom screens that group simple or complex graphs or whatever else you want onto a single page
There are some things to know about Zabbix though. You need to put some thought into items to get accurate values. Is the value you are getting from a device in bits or bytes for example. You can use custom multipliers to convert values into what you want to see.
Honestly, Zabbix is incredibly flexible and this flexibility also gives it a steep learning curve but once you get hosts entered and the templates situated the way you want it becomes very easy to add new hosts down the line. The biggest tip I can give is to make sure you spend a lot of time thinking out how to setup your templates. Zabbix includes a number of them and you'll want to customize them. One thing I found that wasn't a good idea is to make a template and then attach it to a template. It's much easier to join a host to multiple templates.
Did you read the doc? Seems like they thought of that situation. Here is the info
The total amount of time it takes to receive a GET request. The amount of time between receipt of TCP packets on a POST or PUT request. The amount of time between ACKs on transmissions of TCP packets in responses.
Indeed I once was. I have successfully spawned two new processes. However, these new processes consume a lot of resources and we worry that spawning any more might cause the kernel (bank) to OOM (out of money) kill us.
As a parent, you're allowed to kill your children. If you do not wait for your children they'll become zombies and if you die, your children will be adopted by someone else. Maybe you should finger the user before making a connection.
Growl works how you describe. It's one of the reasons I like mac so much and I'm really happy to see it in 9.04. I'm sure with time the notification system will be improved.
I think you're mostly right but it's clear you're not using AD beyond an authentication system for your workstations. Start putting group policies to use and you'll quickly see that Linux/Samba can't compete.
Just here to toot my own horn I guess but I usually find the opposite to be true. I have rarely found support to be overly helpful in solving issues. I trust the Internet before I trust a support contract.
On the late 2007 mac mini (at least) WOL is further made useless by the fact the machine must be booted once and then shutdown in order for WOL to work at all. This means, if power is lost and it comes back WOL won't work.
I'm sorry...but XP is stable. Ubuntu has some issues at times. I watched two of my co-workers reinstall their systems a couple of times in one week because of some serious issues. One was a system that simply crashed and wouldn't reboot. The other one was having no shortage of issues with X. Yea, a person could have done this or that to fix the software but bottom line is that Linux is NOT the panacea everyone makes it out to be.
As much as I want to agree with you (I dislike Linux as a desktop OS) I really don't think that the lack of costly software is the issue. Linux is free and that's the point. The software should be free too. The problem in my mind is the Linux desktop experience is frustrating. Full of "just do this little trick" to make things work. Linux is great if you're willing to tinker and constantly fix all of the minor issues that crop up almost daily. It's also great if you rarely venture out beyond web browsing, chat and email. You can't say that downloading your home video from a camcorder, editing it and uploading it to YouTube is nearly as simple as it is on say a Mac.

He said iMac, not Macbook. AFAIK, you can get the trackpad to work under Ubuntu but it takes additional work after install.

I vote Zabbix. Here's why.
1) Free but offers paid support if you need it
2) Can use agents, snmp or simple checks like ping
3) Agents can be extended with your own scripts and such. If a check isn't built in you can add it. For example, I added a very simple script for checking of MySQL replication had stopped or failed.
4) Templates, makes it easy to add a metric and create a trigger based on that metric to any host attached to that template
5) Triggers can be configured to minimize false positives (multiple dropped packets before sending an alert.
6) You can graph item, group of items or an aggregate value of items in a host group
7) Create your own maps
8) Create custom screens that group simple or complex graphs or whatever else you want onto a single page

UNIX is full of great metaphors and such....
You need to do a bit more research. It most likely is using 2.3, 2.5 or 2.6Ghz
...and put all of my efforts into getting people to stop calling the projector "the powerpoint." "I need to borrow the laptop and powerpoint" BAH!
True. It took a couple of rough nights (for us) but we got our kid sleeping through the night and he still seems to be fine today.
I'm curious how you achieved this, I'm all ears

each employee has a CNAME that is their machine. Seems simple enough

I don't have any trouble finding one for Windows
Why is this funny? It's true. How many CD/DVD burning apps have come out in the past 5 years but we still don't have a DVD ripping tool worth a damn?
Should probably be moderated as redundant
Can't do that

I've been in the Linux business for a while and I had no idea those two projects existed, thanks
Where is it defined that a day is 24 hours?
