[crossposted to plug and plug-newbie lists]
Scenario:
You have your mail servers, dns servers, web servers,
etc. They are on different machines. You have to
monitor them. At the very least you have to monitor:
- network connectivity
- services
- disk space
- free memory
- load
Question:
Ideas on how to monitor them? Best practices?
Recommendations? Suggestions? How do I presently do
it?
- network connectivity and services
- using What's-Up Gold
- disk space, free memory, load
- ssh to each box and then do df, free and
top/ps/uptime
I'm thinking - there must be a better way? SNMP
perhaps? But a colleague mentioned this could
introduce security holes?
Recommendations/suggestions/comments would be highly
appreciated.
Thanks in advance.
