[rrd-users] Re: Adding many data samples at once
You're right about the order of variables. It was a typo!.
I tried your recommendation and still I get the error message:
ERROR while updating 21.rrd: expected 2 data source readings (got 576)
The issue is with LOTS of RRDs the performance lags when you create an RRD
and try to fit a months worth of 5 minutes samples into several rrds at once
(converting some raw 5 minutes samples into rrd files). Right now, to do 10
rrd files at 8928 (number of 5 minutes samples in 31 days) takes 10 to 11
seconds. I'm trying to reduce this into a single RRD update perl file in
order to reduce the overall time to convert.
For those who are interested, here is my complete example:
use RRDs;
# 288 = day
# 2016 = 7 days
# 8928 = 31 days
if (! $ARGV[0]) {
print "\n\nNo Arg specified defaulting to 8928 (31 days)\n";
$ARGV[0] = 8928;
}
print "Total Datapoints: $ARGV[0]\n";
foreach (1..10) {
unlink "2${_}.rrd";
RRDs::create ("2${_}.rrd",
"--start","1",
"DS:input:GAUGE:600:U:U",
"DS:output:GAUGE:600:U:U",
"RRA:AVERAGE:0.5:1:600",
"RRA:AVERAGE:0.5:6:700",
"RRA:AVERAGE:0.5:24:775",
"RRA:AVERAGE:0.5:288:797",
"RRA:MAX:0.5:1:600",
"RRA:MAX:0.5:6:700",
"RRA:MAX:0.5:24:775",
"RRA:MAX:0.5:288:797"
);
}
$StartTime = time();
foreach $c (1 .. 10) {
@DataPoints = undef;
foreach $d (1 .. $ARGV[0]) {
$TimeStamp = time() + ($d * 300);
$in = int(rand(100));
$out = int(rand(100));
push (@DataPoints, "${TimeStamp}:${in}:${out}");
}
#RRDs::update ("2${c}.rrd", @DataPoints);
RRDs::update ("2${c}.rrd", join (" ",@DataPoints));
my $ERR=RRDs::error;
die "ERROR while updating 2${c}.rrd: $ERR\n" if $ERR;
}
$totalTime = time() - $StartTime;
print "total time : $totalTime\n";
I appreciate the help!
Sincerely,
Marc

[rrd-users] Help on listing available DEF fields
Hi, I am new to RRD and have a problem that I think is simple (well, for me it seems simple, but I could find no answer :-) I already have some SNMP machines sending data to MRTG that stores in RRD (this environment was already implemented, but I did not implement anything). Now I need to get data from RRD to use in shell/perl scripts. Reading RRD manpages, I discovered that this can be done with: rrdtool xport \ --start now-1h --end now \ DEF:xx=host-inout.lo.rrd:output:AVERAGE \ DEF:yy=host-inout.lo.rrd:input:AVERAGE \ XPORT:xx:"out bytes" \ XPORT:yy:"in bytes" I'd like to know what can I put in "host-inout.lo.rrd:output" field for all the computers and all the interfaces. Is seems to be a field specification. Is there any way to list all available fields in RRD database?

[rrd-users] How to simply insert and extract data in rrdtool without any averaging
Hi,
we use rrd.tool to insert sample data and extract it to a graph. We
insert data every 10s. We would like to simply store the data and
retrieve it without any averaging done whatsoever.
We use the following command:
rrdtool create ${RRDPATH}/st_${DBNAME}_${HOST}.rrd --start N --step 10
DS:chr:GAUGE:15:0:100 DS:datareads:GAUGE:15:0:20
DS:datawrites:GAUGE:15:0:20 RRA:LAST:0.5:1:8640
But extracting the data from our archive, we see that averaging is done
whenever we set the hearbeat greater than the step. But if we set
heartbeat also to 10s, we get "Unknown" values all the time.
Any hints what we could do?
Thanks very much
Bye Sabine

[rrd-users] Re: Adding many data samples at once
Hi All,
I was having a problem updating an RRD file with multiple data point using
the Perl modules (RRDs).
My dilemma is I need to assemble all my data points ahead of time and then
dump them into the rrd like:
foreach (1..5000) {
$NewTimeStamp = $baseTime + 300;
Push (@DataPoints, "ValIn:ValOut:$NewTimeStamp");
}
RRDs::update ("test.rrd", @DataPoints);
The problem is that this will produce an error because it tells me that it
was looking for 2 data points but got 5000 (in this example). How can I
perform this update in 1 rrd update instead of (much slower) 5000 updates?
Sincerely,
Marc

When the row size of your highest resolution RRA is 1 week, then your database will contain a value for the end of each week. That value will have an epoch timestamp of N x 604800. With N being an integer. The closest N times 604800 may have been at a wednesday for the start of your graph. You want to have the agility to choose the starting day.
