front end syslog logs, ensuring /var/log does not get filled

Looking at the syslog log files on the front end computers shows:

  1. All systems have 2% utilization of /var/log except for h1psl0 (31%) and h1seih45 (30%)
  2. All syslog files have many lines related to inability to log to the central syslogger on occassion
  3. All syslog files have lines related to ntp not able to write to the drift file
  4. h1psl0 and h1seih45 have many lines from monit warning about high system loads

item 4 has been resolved by reconfiguring the /diskless/root/etc/monitrc file on h1boot1 to increase the high loading limit to 8, and not warn on memory or cpu usage. To install this I restarted monit on these systems.

Carlos and I are working on item 2 (central syslogger)

Keith has a solution in place at LLO for item 3 (ntp drift file) which we will implement here.
