Zdravim,

Nasel jsem na to nakej skript, ale ten mi nefunguje

use lib qw( /rrdtool/perl-shared/blib/lib /rrdtool/perl-shared/blib/arch );
  use lib qw( /usr/local/rrdtool-1.0.33/lib/perl /rrdtool/lib/perl );
  use RRDs;

  my $start=time;
  my $rrd=   "/var/www/ping.rrd";
  my $name = "/var/www/ping.png";

  if (not -f $rrd){
  RRDs::create ($rrd, "--start",$start-1, "--step",300,
          "DS:pingtime:GAUGE:600:U:U",
          "RRA:AVERAGE:0.5:1:200",
  );
  my $ERROR = RRDs::error;
  die "$0: unable to create `$rrd': $ERROR\n" if $ERROR;
  };

  my $t;
  $t=`ping -c3 192.168.2.2 | grep round-trip|awk
    '{\$c=split(\$4,i,"/");print i[1]}'`;

  RRDs::update $rrd,"$start:$t";

  RRDs::graph "$name",
    "--title", "Demo ping prehladu",
    "--start", "now-1d",
    "--end", "now",
    "--imgformat","PNG",
    "--width=600",
    "--height=300",
    "DEF:a=$rrd:pingtime:AVERAGE",
    "LINE2:pingtime#00b6e4:real",
    "COMMENT:Aktuálna hodnota odozvy=$t",
  ;
  if ($ERROR = RRDs::error) {
    print "ERROR: $ERROR\n";
  };

Hlasi na radku 3 ( use RRDs; ) chybu:
Can't locate RRDs.pm;

Poradi nekdo? dik

</rrd>

ale divny mi je ze tam nikde nevidim aby to pingovalo.
ale pritom jsem zadaval:
rrdtool update ping2.rrd N:`ping -c3 192.168.2.2 | grep round-trip|awk
'{$c=split($4,i,"/");print i[1]}'`

cim to? Dik

jestli chces opakovany pravidelny spousteni, tak neni nic jednodussiho, nez to dat do crona, ne?

Viz wohma, crontab -e by melo byt reseni, napises tam cestu k tomu scriptu a pred to dle manu kdy se ma spoustet. Nektery distra maj v /etc/ adresare jako hourly, ... takze staci dat script do nich.
