This rule
checks whether there is enough swap space.

rhltm001
|
CPU power is wasted each time a CPU has to wait for
a lock to become free. This event is counted because the kernel uses mutually
exclusive locks to synchronize its operation and to keep multiple CPUs from
concurrently accessing critical code and data regions.

NFS
remote procedure call timeouts may be associated with duplicate responses
after the call is retransmitted. These timeouts indicate that the network
is okay but the server is responding slowly.

|
rhltm003
|
The
run queue length is divided by the number of CPUs because every CPU takes
a job off the run queue in each time slice.

rhltm004
|
A busy disk or a
slow disk reduces system throughput and increases user response times. This
rule identifies the disks that are loaded so that the load can be rebalanced.

rhltm005
|
RAM rule based on residency time
for an unreferenced page. The virtual memory system indicates that the system
needs more memory when the system scans to look for idle pages to reclaim
for other uses.

rhltm006
|
This rule refers to the problem with kernel memory
allocation that occurs when login attempts or network connections fail unexpectedly.
There are two possible causes: Either the kernel has reached the extent of
its address space, or the free list does not contain any pages to allocate.
The repeated failures signify a problem that might otherwise be overlooked.

rhltm007
|
A global cache of directory path name components exists.
This cache is called the directory name lookup cache (DNLC). If this cache
does not exist, directory entries must be read from disk and be scanned to
locate the right file.
