Table 7-5 “Examples of System Resource Requests” shows examples
of how you can monitor system resources.
Table 7-5 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.
