Q
When focusing a report, it can sometimes be helpful to also use a detail level of
0
or
1
. In this case the report will show only a count of number of matches (for
detail
0
) and just the highest level of the entity which matches (for detail
1
).
5.4.3.3.1
Advanced Focus
The node name, node name pattern, node guid, node type, IOC name, IOC name
pattern, IOC GUID, IOC type and system image GUID also allow for a port
number specifier. This permits the focus to be limited to the given port number.
If the selection resolves to multiple switches or CAs (for example a system
composed of multiple nodes), all ports on the present fabric matching the given
port number will be selected.
An even more advanced form of focus is to focus on the route between any two
points. This will focus on all the ports involved in that route and can be an
excellent way to focus in quickly on a performance or error situation which is
being reported between 2 specific points in the fabric (Such as a
StatusTimeoutRetry
that MPI may be reporting between 2 processes in its
run).
Focus can use glob style patterns. This permits a wildcarded focus by node
name or IOC name. If a naming convention is used for fabric components, this
can provide a powerful way to focus reports on nodes. For example, if the host
names are prefixed with an indication of their purpose, searches can be
performed based on the purpose of the node. For example if the following naming
convention is used:
l###
= login node ###,
n###
= compute node ###,
s###
=
storage node ###, etc. Node purposes can be focused by using patterns such
as
'l*'
,
'n*'
or
's*'
.
NOTE:
A glob style pattern is a shell style wildcard pattern as used by
bash
and
many other tools. When using such patterns they should be single quoted
so that the shell will not try to expand them to match local file names.
Typically a focused report will include a summary at its start of the items focused
on. When the focus has a large scope, this list can be quite long. In this case
the
-Q
option can be used to omit this section from the report.
