...finds the Tnnn and stores it (out1) then goes looking for the " A1" and stores that (out2) if found. Then prints both stored strings if they have been set. This works but is getting a bit long for a one-liner
can you take input from another command and do printf?
such as
awk '{print $2,$1}' | sort -k1,1 -k2,2 | printf "%-10s,%15s"
this does not work.. but there must be a way.. please help me..
thank you. (3 Replies)

rrdxport
RRDXPORT(1) rrdtool RRDXPORT(1)NAME
rrdxport - Export data in XML format based on data from one or several RRD
SYNOPSIS
rrdtool xport [-s|--start seconds] [-e|--end seconds] [-m|--maxrows rows] [--step value] [--daemon address] [DEF:vname=rrd:ds-name:CF]
[CDEF:vname=rpn-expression] [XPORT:vname[:legend]]
DESCRIPTION
The xport function's main purpose is to write an XML formatted representation of the data stored in one or several RRDs. It can also
extract numerical reports.
If no XPORT statements are found, there will be no output.
-s|--start seconds (default end-1day)
The time when the exported range should begin. Time in seconds since epoch (1970-01-01) is required. Negative numbers are relative to
the current time. By default one day worth of data will be printed. See also AT-STYLE TIME SPECIFICATION section in the rrdfetch
documentation for a detailed explanation on how to specify time.
-e|--end seconds (default now)
The time when the exported range should end. Time in seconds since epoch. See also AT-STYLE TIME SPECIFICATION section in the rrdfetch
documentation for a detailed explanation of ways to specify time.
-m|--maxrows rows (default 400 rows)
This works like the -w|--width parameter of rrdgraph. In fact it is exactly the same, but the parameter was renamed to describe its
purpose in this module. See rrdgraph documentation for details.
--step value (default automatic)
See rrdgraph documentation.
--daemon address
Address of the rrdcached daemon. If specified, a "flush" command is sent to the server before reading the RRD files. This allows
rrdtool to return fresh data even if the daemon is configured to cache values for a long time. For a list of accepted formats, see the
-l option in the rrdcached manual.
rrdtool xport --daemon unix:/var/run/rrdcached.sock ...
--enumds
The generated xml should contain the data values in enumerated tags.
<v0>val</v0><v1>val</v1>
DEF:vname=rrd:ds-name:CF
See rrdgraph documentation.
CDEF:vname=rpn-expression
See rrdgraph documentation.
XPORT:vname::legend
At least one XPORT statement should be present. The values referenced by vname are printed. Optionally add a legend.
Output format
The output is enclosed in an xport element and contains two blocks. The first block is enclosed by a meta element and contains some meta
data. The second block is enclosed by a data element and contains the data rows.
Let's assume that the xport command looks like this:
rrdtool xport
--start now-1h --end now
DEF:xx=host-inout.lo.rrd:output:AVERAGE
DEF:yy=host-inout.lo.rrd:input:AVERAGE
CDEF:aa=xx,yy,+,8,*
XPORT:xx:"out bytes"
XPORT:aa:"in and out bits"
The resulting meta data section is (the values will depend on the RRD characteristics):
<meta>
<start>1020611700</start>
<step>300</step>
<end>1020615600</end>
<rows>14</rows>
<columns>2</columns>
<legend>
<entry>out bytes</entry>
<entry>in and out bits</entry>
</legend>
</meta>
The resulting data section is:

EXAMPLE 2

XPORT:out2:"if2 out bytes"
XPORT:sum:"output sum"
ENVIRONMENT VARIABLES
The following environment variables may be used to change the behavior of "rrdtool xport":
RRDCACHED_ADDRESS
If this environment variable is set it will have the same effect as specifying the "--daemon" option on the command line. If both are
present, the command line argument takes precedence.
