# processing parameters according, if possible. The best example of this is
# if one generates one log based on -scd and a second on -scm. By forcing
# the processing of both to be -scdm, the resultant 'tab' file will contain
# everything. Alas, things get more complicated with detail files and even
# more so with lustre detail files if filesystems are mounted/umounted, etc.
# In any event, the details are in the code...

The following subsystems can be specified in any combinations with -s or

These generate summary, which is the total of ALL data for a particular type
b - buddy info (memory fragmentation)
c - cpu
d - disk
f - nfs
i - inodes
j - interrupts by CPU
m - memory
n - network
s - sockets
t - tcp
x - interconnect (currently supported: OFED/Infiniband)
y - slabs
These generate detail data, typically but not limited to the device level
C - individual CPUs, including interrupts if -sj or -sJ
D - individual Disks
E - environmental (fan, power, temp) [requires ipmitool]
F - nfs data
J - interrupts by CPU by interrupt number
M - memory numa/node
N - individual Networks
T - tcp details (lots of data!)
X - interconnect ports/rails (Infiniband/Quadrics)
Y - slabs/slubs
Z - processes
An alternative format lets you add and/or subtract subsystems to the defaults by
immediately following -s with a + and/or -
eg: -s+YZ-x adds slabs & processes and removes interconnet summary data
-s-n removes network summary data
-s-all removes ALL subsystems, something that can handy when playing back

Date and Time
d - preface output with 'mm/dd hh:mm:ss'
D - preface outout with 'ddmmyyyy hh:mm:ss'
T - preface output with time only
U - preface output with UTC time
m - when reporting times, include milli-secs
Numerical Formats
g - include/substitute 'g' for decimal point for numbers > 1G
G - include decimal point (when it will fit) for numbers > 1G
Exception Reporting
x - report exceptions only (see man page)
X - record all values + exceptions in plot format (see manpage)
Modify results before display (do NOT effect collection)
n - do NOT normalize rates to units/second
Plot File Naming/Creation
a - if plotfile exists, append [default=skip -p file]
c - always create new plot file
u - create unique plot file names - include time
Plot Data Format
1 - plot format with 1 decimal place of precision
2 - plot format with 2 decimal places of precision
z - don't compress output file(s)
File Header Information
i - include file header in output

sub showSubopts
{
my $subopts=<<EOF5;
These options are all subsystem specific and all take one or more arguments.
Options typically effect the type of data collectl and filters effect the way
it is displayed. In the case of lustre there are also 'services'
CPU
--cpuopts
z - do not show any detail lines which are ALL 0
--cpufilt perl-regx[,perl-regx...]
this works the same way as dskfilt and netfilt in that it only applies
to output and not data collection. Only data for CPU numbers that
match the pattern(s) will be included in summary stats or displayed
when details are requested. This is mainly here for machines with
high cpu counts which would otherwise overwhelm the detail output.
HINT: you specify the range 1 to 3 in perl like this: 1..3 but collectl
also allows 1-3 (which is NOT perl) for ease of use
Disk
--dskfilt perl-regx[,perl-regx...]
this ONLY applies to disk stats output and not data collection
only data for disk names that match the pattern(s) will be
included in summary stats or displayed when details requested
if you don't know perl, a partial string will usually work too
--dskopts
f - include fractions for some of the detail output columns
i - include average i/o size in brief mode (as with --iosize)
o - exclude unused devices from new headers and plot data
see docs on disk monitoring for more detail
z - do not show any detail lines which are ALL 0
--rawdskfilt
this works like dskfilt except rather than being applied to the
output it applies to the data collection.
--rawdskignore
this is the opposite if --rawdskfilt in that any disks matching this
pattern will not have their statistics recorded as well as not being
shown in any output
Environmental
--envopts [def=fpt] NOTE: these do not filter data on collection
f - display fan data
p - display power data
t - display temperature data
C - display temperature in celcius
F - display temperature in fahrenheit
M - display data on multiple lines (useful when too much data)
T - display all env data truncated to whole integers
0-9 - use as ipmi device number
--envfilt perl-regx
during collection, this filter is applied to the data returned by
ipmitool and only those lines that match are kept
--envremap perl-regx...
a list of regx expressions, comma separated, are applied to the
final env names before reporting
The following are for those needed to develop/debug remapping rules.
See online documentation OR Ipmi.html in docs/
--envrules filename file containin remapping rules
--envdebug show processing of ipmi data
--envtest filename file containing extract of 'ipmitool -c sdr'
Interconnect
--xopts
i - include i/o sizes in brief mode
Interrupts
--intfilt perl-regx
like other filters, this filter only applies to display output
and all interrupts will always be collected and available for
playback
Lustre
--lustopts
B - only for OST's and clients, collect buffer/rpc stats
D - collect lustre disk stats (HPSFS: MDS and OSS only)
M - collect lustre client metadata
O - collect lustre OST level stats (detail mode only and not MDS)
R - collect lustre client readahead stats
--lustsvc: force monitoring/reporting of these lustre services
c - client
m - mds
o - oss
NOTE - you can specify the service in either lower or upper case, in
case other tools might care. see the collectl documentation on lustre
for details
Memory
--memopts
P - display physical portion of verbose display
V - display virtual portion of verbose display
p - display/record alloc/refill number of pages
s - display/record steal/kswap/direct number of pages
R - show changes in memory as rates, not instantaneous values
note that including p or s will collect more data and will slightly increase in processing
time. if neither P or V are specified none of the basic memory stats will be displayed BUT
they will be recorded making it possible to display later either by including P/V as an
option OR leaving off both p and s.
Network
--netfilt perl-regx[,perl-regx...]
this ONLY applies to network stats output and not data collection
only data for network names that match the pattern(s) will be
included in summary stats or displayed when details requested
if you don't know perl, a partial string will usually work too
--netopts eEw99
e - include errors in brief mode and explicit error types in
verbose and detail formats
E - only display intervals which have network errors in them
i - include i/o sizes in brief mode
o - exclude unused devices from new headers and plot data
see docs on network monitoring for more detail
w - sets minimal network name width in network stats output which
can be useful for aligning output from multiple systems
--rawnetfilt
this works like netfilt except rather than being applied to the
output it applies to the data collection.
--rawnetignore
this is the opposite of --rawnetfilt in that any networks matching this
pattern will not have their statistics recorded as well as not being
shown in any output
NFS
--nfsfilt TypeVer,...
C - client
S - server
2 - V2
3 - V3
4 - V4
By specifying a csv list, collectl will only collect/record the type
of data indicated (eg c3,s3 indicates V3 clients/server data)
--nfsopts
z - do not show lines of 0 activity with -sF
Processes
--procopts
c - include cpu time of children who have exited (same as ps S switch)
f - use cumulative totals for page faults in proc data instead of rates
i - show io counters in display
I - disable collection/display of I/O stats. saves over 25% in data
collection overhead
k - remove known shells from process names
m - show memory breakdown and faults in display
p - never look for new pids or threads to match processing criteria
This also improves performance!
r - show root command name for a narrower display, can be combined with w
R - show ALL process priorities ('RT' currently displayed if realtime)
s - include process start times in hh:mm:ss format
S - include process start times in mmmdd-hh:mm:ss format
t - include ALL threads (can be a lot of overhead if many active threads)
u - make username format 12 chars wide. you can also set any arbitrary
width of at least 8, eg u10
w - make format wider by including entire process argument string
you can also set a max number of chars, eg w32
x - include extended process attributes (currently only for context switches)
z - exclude any processes with 0 in sort field
--procfilt: restricts which procs are listed, where 'procs' is of the
Format: <type><match>[[,<type><match>],...], and valid types are any
combinations of:
c - any substring in command name
C - command name starts with this string
f - full path of command (including args) contains string
p - pid
P - parent pid
u - any processes owned by this user's UID or in range xxx-yyy
U - any processes owned by this user
NOTE1: if 'procs' is actually a filename, that file will be read and all
lines concatenated together, comma separted, as if typed in as an
argument of --procfilt. Lines beginning with # will be ignored
as comments and blank lines will be skipped.
NOTE2: if any type fields are immediatly followed by a plus sign, any
threads associated with that process will also be reported.
see man page for important restrictions
--procstate Only show processes in one or more of the following states
D - waiting in uninterruptable disk sleep
R - running
S - sleeping in uninterruptable wait
T - traced or stopped
W - paging
Z - zombie
Slab Options and Filters
--slabopts
s - only show slabs with non-zero allocations
S - only show slabs that have changed since last interval
--slabfilt: restricts which slabs are listed, where 'slab's is of the form:
'slab[,slab...]. only slabs whose names start with this name
will be included
TCP Stack Options - these DO effect data collection as well as printing
--tcpfilt
i - ip stats
t - tcp stats
u - udp stats
c - Icmp Stats
I - ip extended stats, no brief stats so including it will force --verbose
T - tcp extended stats

The full format of the --top switch is:
--top sort[,num[,v]]
If the 3rd parameter is specified, currently only 'v' is supported,
top will not display in top format but rather in vertical mode.
This can be very handy when you want to see output as with --top in
playback mode.
The following is a list of --top's sort types which apply to either
process or slab data. In some cases you may be allowed to sort
by a field that is not part of the display if you so desire. If not
specified the default is 'time'.
TOP PROCESS SORT FIELDS
Memory
vsz virtual memory
rss resident (physical) memory
Time
syst system time
usrt user time
time total time
accum accumulated time
I/O
rkb KB read
wkb KB written
iokb total I/O KB
rkbc KB read from pagecache
wkbc KB written to pagecache
iokbc total pagecacge I/O
ioall total I/O KB (iokb+iokbc)
rsys read system calls
wsys write system calls
iosys total system calls
iocncl Cancelled write bytes
Page Faults
majf major page faults
minf minor page faults
flt total page faults
Context Switches
vctx volunary context switches
nctx non-voluntary context switches
Miscellaneous (best when used with --procfilt)
cpu cpu number
pid process pid
thread total process threads (not counting main)
TOP SLAB SORT FIELDS
numobj total number of slab objects
actobj active slab objects
objsize sizes of slab objects
numslab number of slabs
objslab number of objects in a slab
totsize total memory sizes taken by slabs
totchg change in memory sizes
totpct percent change in memory sizes
name slab names
