SWMU System Swap Memory Used; measured in
bytes.
Values less than 100 MB are considered
normal; over 500 MB is a major issue.
If a service is persistently using
large amounts of the virtual
memory swap storage, upgrade
the amount of RAM in the server.
TNER Network Neighbor Drift; an indication in
µs of how far the clock is drifting should
it become disconnected from a GPS
system.
Absolute values more than 1,000,000 (1 s)
are a minor issue. Twice that is considered
a major issue. If slow by 2 s, the situation
could be critical.
If the drift becomes large either in
the positive or negative direction,
this should be investigated imme-
diately, contact HP technical
support.
TRFS Reference Clock; an indication of the
status of the reference clock:
• 0=Stable
• 1 = Flywheeling
• 2=Unstable
• 3 = Offline
• 4=Unknown
If the reference clock starts fly-
wheeling, this means it is drifting
and there is no way to determine
the accuracy of the clock. If this
occurs, check the connections with
the GPS, and if it persists, contact
HP technical support. If it then
becomes “Unstable”, “Offline” or
“Unknown”, contact HP technical
support immediately.
TRSS Local Clock Status; an indication of the
status of the local clock:
• 0 = Calibrating
• 1 = Synchronizing
• 2=Syntonizing
• 3 = Flywheeling (Recalibrating)
• 4 = Flywheeling
Only “Flywheeling” is considered
problematic.
If the local clock starts flywheel-
ing, contact HP technical support.
UMEM Utilized Memory; the amount of system
RAM (in MB) remaining available for
system operations.
Anything over 100 MB is considered
normal. Below 50 MB is a major issue;
below 10 MB is critical.
If the available RAM gets fairly
low, it needs to be investigated as
to whether this is a hardware or
software issue. If it is determined
not to be a hardware issue, or if it
falls below 50 MB, contact HP
technical support immediately.
