Table 5-4 “Examples
of System Resource Requests” shows examples of how
you might monitor system resources.
Table 5-4 Examples
of System Resource Requests
To be alerted when... | Resources to monitor | Monitoring Parameters |
|---|
Notify | | Value | Option |
|---|
fewer than 5 users are on the node, for
running backups | /system/numUsers | when value is | < | 5 | |
more than 20 users are on the node, for
load balancing, and when value returns to below 20 users | /system/numUsers | when value is | > | 20 | RETURN |
system load is high | /system/jobQueue1Min | when value is | > | 7 | INITIAL |
/system/jobQueue5Min | when value is | > | 4 | INITIAL |
/system/jobQueue15Min | when value is | > | 3 | INITIAL |
file systems are running out of space | /system/filesystem/availMb for:
/home
/opt
/root
/stand
/tmp
/usr
/var | when value is | < | 50 | INITIAL |
The job queue and file system resources have the INITIAL option
set to give a baseline for comparison. The job queue threshold value
decreases for the longer job queues because the longer something
is in the queue, the more likely it is that a node needs to be load
balanced.
