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 This assumes that your master database isn't over loaded trying to replicate data to slaves as the now out of date slave is going to need a lot of data to get caught up.

Comment Zabbix (Score 1) 342 342

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

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.

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.
