What monitoring/management tools do you use?
scorchin: I work for a web development firm and we handle a lot of large intranets for big internationals. Most of the systems are built using combinations (pick two) of PHP, JSP, Ruby, Perl, MySQL and Oracle.The servers (total around 60) tend to be spread across different continents and it always helps to have as much information as possible.We were originally using Nagios, but found that it was lacking some of the tools that we required. Instead we switched over to Zabbix and have hooked into it using a custom PHP/Python application.This custom app just provides a worldwide view of traffic, points out specific spike times and most importantly: shows the nearest commits to the master repos when spikes occur.The main reason for switching over to Zabbix was the documentation and API. It made creating our own tools a lot easier.Info that might be useful:- Running on CentOS- Apache webservers with nginx front-ends- Database servers work in teams of 3, with master-master replication and then a slave.
