rhltm000
|
This rule checks whether there is enough swap space.

Critical, Alert, Caution

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.

rhltm002
|
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.
|
Critical, Alert, Caution
|
|
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.
|
Critical, Alert, Caution
|
|
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.
