Code:
#!/usr/bin/perl

# SOME VARIABLE

print "Enter a number = ";

$nSlices1 = <STDIN>;
chomp $nSlices1;

It seems that perl sprintf uses the round-to-even method: foreach my $i ( 0.5, 1.5, 2.5, 3.5 ) { printf "$i -> %.0f\n", $i; } __END__ 0.5 -> 0 1.5 -> 2 2.5 -> 2 3.5 -> 4 4.5 -> 4 Where we probably wants to use round-half-up, i.e. output should be as below: 0.5 -> 1 1.5 -> 2... (8 Replies)

vrstat

vrstat(1M)																vrstat(1M)

NAME

       vrstat - display statistical information for volumes in RVGs and RLINKs, and for all hosts in an RDS

SYNOPSIS

       vrstat [-g diskgroup] [-V] [-S] [-R] [-M] [-n number] [rvg ...]

DESCRIPTION

       The  vrstat  command  prints  statistical information for the volumes in Replicated Volume Groups (RVGs) and RLINKs, and for all hosts in a
       Replicated Data Set (RDS).  Information is displayed across the RDS setup on all the hosts, and not for a specific host.

       By default, the command displays statistics at intervals of 10 seconds.	This interval can be changed by setting  the  VRAS_STATS_FREQUENCY
       environment variable to the required value in the /etc/vx/vras/vras_env file.

       If  no  rvg  argument is specified, the command displays information for the RLINKs, storage replicator logs (SRLs), data volumes or memory
       tunables across all the RDSs on the local host, depending on the option that is specified.

       If no option or argument is specified, the vrstat command displays the consolidated status for the RLINKs, SRLs, data  volumes  and  memory
       tunables of all RDSs on the local host.

       For more information on the output formats, see the vxrlink(1M), vxstat(1M) and vxmemstat(1M) manual pages.

OPTIONS

       -g diskgroup
		 Specifies  the  disk  group  for the operation.  If the -g option is not specified, the rvg argument determines the default local
		 disk group, according to the standard disk group selection rules that are described on the vxdg(1M) manual page.

       -M	 Displays detailed information for the memory tunables on every host in an RDS.  The output from this option is  similar  to  that
		 from the vxmemstat command.

       -n number Displays the statistics number times, and then exits.

       -R	 Displays RLINK-related statistical information for all hosts in an RDS.  The output from this option combines the output from the
		 vxrlink stats and vxrlink status commands, and also displays bandwidth utilization by the RLINK.  This  output  can  be  used	to
		 diagnose connectivity and network problems.

       -S	 Displays statistical information for SRL volumes on all hosts in an RDS.

       -V	 Displays statistical information for data volumes on all hosts in an RDS.

EXIT CODES

       The  vrstat  utility  exits  with a status of 0 if the attempted operation succeeds. It exits with a status of 1 if the attempted operation
       fails.  This exit code is the same for all errors.

EXAMPLES

       Display statistical information for all RLINKs in an RDS across all hosts:

	      vrstat -R egrvg

       Display consolidated statistical information for all RLINKs, SRLs, data volumes and memory tunables for all RDSs on a host:

	      vrstat
