table is not cleared out (see Section 10.2.2).
Table 10.4: Performance Statistics Attributes
Attribute Default Description
node-statistics cpu statistics collected per node
cpu-stats-poll-
interval
120 time in seconds between CPU samples
data-lifetime 48 time in hours to keep job data
stats-lifetime 24 time in hours to keep statistical data
The server attributes in Table 10.5 control the behavior of the RMS daemons. All of the
modification times are in UTC. Client applications should convert this to local time and
print it as a string.
If the attribute node-status-poll-interval is not set or set to zero, the value of
rms-poll-interval is used instead.
Table 10.5: Server Attributes

interval
0 time between monitoring node status
status-modify-time last time the status changed
resource-modify-
time
last time a resource was modified
version RMS version number
altzone 0 shift in seconds to apply to UTC time to

The attributes in Table 10.6 control the scheduling of parallel programs. If the number
of resource requests reaches pmanager-queuedepth, subsequent requests either block
or fail immediately (if the immediate option to prun has been selected). The blocked
requests do not appear in the database. If the pmanager-idletimeout is exceeded, the
resource times out with an exit status of 125.
