OK. Is there any other data I can gather right now? The problem
takes a few months to manifest, but once it does it gets pretty bad.
That gives us narrow, rare windows to get useful data.
I would monitor the system(s) OS behavior with (example) collectd at
least cpu, memory, load, iowait. Additional any either query/behavior
specific monitoring can be implemented using collectd plugins like
perl/python
and additional the generic available stats like provided through
cn=snmp,cn=monitor
