Schedule NER and notifications.

Since I don't want NER to notify me of poor performance on nights and weekends I just created a pair of cron jobs to start and stop NER on weekdays only.
# the cron jobs... crontab -e from root on Centos add the following lines. If you don't know vi you need to
0 6 * * 1-5 /ner/bin/launch_ner start
0 18 * * 1-5 /ner/bin/kill-ner
So now NER starts at 6am and stops at 6pm only on work days. This will also conserve disk space since I am not recording all those extra packets generated by backups.
I also created a pair of notifications. One that reports high file utilization >3.5Gb for the last 700 minutes. This will generate a report at the end of the day of high users. We have been chasing down users that abuse the server and that has worked well.
On NER v1.2 the latency is graphed differently than 1.1. The notification for slow file server performance is working well with latency set to >400ms.
