I've been using Ganglia to monitor my single Mac OSX server which runs Apache and MySQL. I'm ok with it.
Now we are upgrading our servers, 6 IBM X3650 M3 and 2 Fujitsu servers. 2 IBM for Apache cluster and 4 IBM for MySQL NDB Cluster. The other two servers are for Load balancers.
All servers are going to run Debian Lenny 5 on it.
Now I need to decide on which monitoring tool I should go for. I found that BixData and Zabbix does an excellent job than Ganglia, in terms of sensors and reporting.
Have anyone tried the above two tools? And which tool would you suggest me? For Debian. As I'm writing this, I'm installing BixData to try....
Thanks in advance.
