For the record. rrdtool (although a rather old version 1.3.8) _is_ part of RHEL6 and can be found in the rhel-x86_64-server-optional-6 channel. You should change the channel subscriptions of your server accordingly. Futhermore the tar archive also contains a spec file for an RPM build. Depending on your site policy you may build the RPMs from that file (didn't test it myself for 1.5.5 so you may adjust some settings) and setup a "3rd party" repository. Sincerely yours, Andreas Maus. P.S.: Redhat Enterprise Linux 6.4 is really old, it was released over three years ago (february or march 2013 if I recall correctly). The current version of RHEL6 is 6.7. -- Dipl.-Ing.

Re: [rrd-users] Fwd: start time
Hello.
man rrdfetch says something about the format -s accepts:
--start|-s start (default end-1day)
start of the time series. A 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 fetched.
See also AT-STYLE TIME SPECIFICATION section for a detailed explanation on
ways to specify the start time.
So -s 3600 is not valid, except you are trying to access data from Thu Jan 1
01:00:00 UTC 1970
So you should use an unix timestamp (e.g. -s 1309512280) or use a negative
number
to specify a relative offset.
HTH,
Andreas Maus.

Time drift? I've seen something like that on systems with a unstable

Try using the correct time (date +'%s' on Linux) instead of N.
e.g.:
now=`date +'%s'`
rrdtool update [...] ${now}:[...]
(and check the values of $now)
and of course run ntp to keep your system time stable.

Is this an error of your mailclient or is it indeed in your command?
Can you attach the script (to avoid error due copy and paste)?
*Here i stumbled on first error.
ERROR: expected timestamp not found in data source from
N:2991935:6312:44368311:5850271:1302:318461263: not found
Well maybe the magic '?' in the command is _really_ in the command.
This error indicates that you called:
rrdtool update ... _AND_ then ?N:$mail_input:$...
(These are two errors. expected timestamp from rrdtool and 18461263: not
found from the shell).
It says it doesnt know what N is! Mkay, i write another line dates=`date +%s

and add $dates instead of N.
Ok no Errors.
Next i try to graph it all. With following sh file

Read the error message again!
You run rrdupdate /var/lib/rrd/outside.rrd N:'snmpget -c ...
This is not what you want! You have to fix your quoting.
You want something like rrdupdate /var/lib/rrd/outside.rrd N:`snmpget -c ...
(Notice the backtic ` instead the single quote ' !)
Anyway I recommend storing the output inside a shell variable like:
in1=`snmpget -c public -v 1 -Oqv 192.168.1.1 ifInOctets.1`
and use this in your rrdtool call:
rrdtool update ... N:${in1} ...
This would result in a more readable code ;)

I didn't thought about the amount of data because I assumed the rrdfiles were stored on an external USB disk (the Asus has external USB 2.0 ports). I have rrd-files with 1 to ~8 ds and two rra's. It takes about 50 seconds to dump a file with one ds and 70 seconds for a file with 3 ds'es. I plan to have about 30 rrd-files, so it would take about 30 minutes just to convert then. I see. That is really a problem. Another problem is that the ASUS is located in Singapore, and the central server in Sweden. The communication between them is via an quite slow VPN-link. Ouch! Now _that_ is a long distance !;) An rrd-file with one ds is 730kB and the corresponding xml-file is 6.6MB, so its almost ten times more data to transfer between the hosts! Hmmm ... How about compressing the XML data before you transfer it using gzip or bzip2 ? OTOH this will require some CPU additional cycles. What is the difference between the rrd-files? The ASUS is MIPS-based and the central server is an PC. Both platforms are 32-bit, but the PC is little-endian and MIPS is big. If this is the only difference, it should not be so hard for an C-programmer to write routine that converts the rrd-files between different architectures... Ahhh no. Unfortunately it is not that trivial. Although IEEE specify the format of floating numbers the represantation of floats also depends on the architecture. There are different representations of some magic floats like -NaN, +NaN, Inf,-1,+1. Even the alignment may vary!

Hi Erik. On Wed, Nov 08, 2006 at 08:35:23AM +0100, Erik wrote: I've got some 8000+ rrdfiles in a dir and i am trying to create a graph containing the sum from a selecton of about 1700 rrdfiles.

The problem now is that RRDtool segfaults, is there any other way to create an aggregate graph for my files? Depending on your RRD-Files you should watch your memory. Generating graphs from many files may result in a rrdtool process consuming large amount of memory. So make sure you have enough memory. (and watch your syslog files for out-of-memory conditions).

Hi,

Is it possible from proc to get it?
Sure.
What OS you are talking about?
Linux? If you use Linux which kernel version?
2.4.x? 2.6.x? Which architecture? x86? x86_64? ia64?
I want to draw the graph of cpu usage of my machine. I am giving my
DS design.
So please help me how to put the data in to it from proc
or any other way.
The solution is in man 5 proc for Kernel 2.4.x:
[... snipp ...]
/proc/stat
kernel/system statistics. Varies with architecture. Common
entries include:
cpu 3357 0 4313 1362393
The amount of time, measured in units of USER_HZ (1/100ths
of a second on most architectures), that the system spent in user mode, user
mode with low priority (nice), system
mode, and the idle task, respectively. The last value
should be USER_HZ times the second entry in the uptime pseudo-file.
In Linux 2.6 this line includes three additional columns:
iowait - time waiting for I/O to complete (since 2.5.41); irq - time
servicing interrupts (since 2.6.0-test4);
softirq - time servicing softirqs (since 2.6.0-test4).
[... snipp ...]
and for Kernel 2.6.x:
[... snipp ...]
/proc/stat
kernel/system statistics. Varies with architecture. Common
entries include:
cpu 3357 0 4313 1362393
The number of jiffies (1/100ths of a second) that the
system spent in user mode, user mode with low priority (nice), system mode, and
the idle task, respectively. The last
value should be 100 times the second entry in the uptime
pseudo-file.
[... snipp ...]
I am not using SNMP.
Do you collect the data using a Shellscript? Perl?
Using the information from /proc/stat you should change
your GAUGE declarations to COUNTER (or save the last
values, fetch the new one and calculate the difference,
so it is far much easier to use COUNTERs).
If you change the GAUGEs to COUNTERs you can use:
- with Kernel 2.4:
# Get user:nice:system:idle
cpudata=`grep '^cpu ' /proc/stat | sed -e 's/^cpu */N:/' -e 's/ /:/g'`
rrdtool upadte $rrd/cpu.rrd $cpudata
- with Kernel 2.6 (I will count the iowait,irq,softirq and values as system
values):
cpudata=`grep '^cpu ' /proc/stat | awk '{print N:$2:$3:$4+$6+$7:$5;}'`
rrdtool update $rrd/cpu.rrd $cpudata

Hi.
hello everybody !!
i am new to RRDTool.
Welcome ;)
Here is a problem (may be simple one )
I am presently collecting the statuses of Network Devices (routers,etc).I am
able to plot the graphs.
But My requirement is that
When Somebody supplies a date (Start and End not in SECs) I should be able
to list the averages(or Max) per day between the given 2 dates in a tabular
form with dates.
Thats not too complicated.
Assuming the resolution of your RRD-Databases is fits your needs.
First you have to convert the supplied date into the corresponding
UN*X epoch (seconds since 01-Jan-1970 00:00 UTC).
In PERL you can use the Time::Local module (should be installed
or get it from http://search.cpan.org/~drolsky/Time-Local-1.12/) and
do something like:
$time = timelocal($sec,$min,$hour,$mday,$mon,$year);
Having the start and stop date in the right format you can use
the xport function from the RRDs perl module (you can even do
math with this module !).
Now all you have todo to work with the data RRDs::xport() gave
you. E.g.:
- call RRDs::xport() and it will return an array
my ($start,$end,$step,$columcnt,$legend,$data)=RRDs::xport(@cmd);
- loop over the data the call to RRDs::xport() returned
(convert the seconds since 01-Jan-1970 00:00 back to a normal date
using the buildin PERL function localtime) and print your table
foreach my $row (@$data)
{
(undef,my $min,my $hour,my $mday,my $mon,my
$year,undef,undef,undef)=localtime($start);
$line.=sprintf(%u\t%02u-%s-%04u
%02u:%02u,$start,$mday,$Months[$mon],$year+1900,$hour,$min);
$start+=$step;
foreach my $val (@$row)
{
if ($val ne '')
{
$line.=sprintf(\t%.2f,$val);
} else
{
$line.=sprintf(\t-\n,$val);
}
}
}
Easy, isn't it ?

Andreas.

Set your coresize to unlimited, run your program - it caught a SIGSEGV so a core dump will be generated.

On Wed, Sep 07, 2005 at 11:26:44AM -0700, Steve wrote:
Hi Steve.
Hi,
Is there any documentation of the rrdtool-API?
Uhhh... I think there is no documentation available.
But for the non-threaded functions I have some knowledge
in /dev/brain :)
I would like to update RRD from a C program.
Thats really easy ...
The update function is declared as:
int rrd_update(int rrd_argc, char **rrd_argv);
Similar to the usual main-Function inside a normal program
int is the number of arguments (ala argc) and char ** (ala argv)
is a an array of char * .
The array rrd_argv contains rrd_argc elements (from 0..rrd_argc-1)
and the element rrd_argv[rrd_argc] _MUST_ be NULL.
The function does not care about rrd_argv[0] so it can be anything
(but not NULL). I recommend that you put the name of the function
(update in this case) that uses this array in this field.
There is no difference calling the update function from command line
(via rrdtool update ... ) or from a C program. The parameters for
this routine are the same as described in the manual page for rrdupdate.
So lets assume I want to update the file test.rrd (located in my $HOME)
with the value N:1:1:1 (it holds three DS). All I have to do is to
construct the array rrd_argv and set rrd_argc.
The commandline from a shell would look like:
[EMAIL PROTECTED] ~ # rrdtool update /home/maus/test.rrd N:1:1:1
and so the corresponding structures in the API-Call will:
rrd_argv[0]=update
rrd_argv[1]=/home/maus/test.rrd
rrd_argv[2]=N:1:1:1
rrd_argv[3]=NULL
rrd_argc=3
Then call:
int rrd_ret=rrd_update(rrd_argc,rrd_argv);
rrd_ret is 0 on success
It is a good advice to call rrd_clear_error() before you call rrd_update to
possible errors. You can also test for errors using the function
rrd_test_error()
-a return value of 0 means no error. A string describing the error can be
obtained
by calling rrd_get_error().
PITFALLS AND COMMON PROBLEMS:
A lot of obscure problems arise if you forget about the variables optind and
opterr.
These variables are declared in the getopt headerfile (used for parsing the
options)
as _global_ ! So you have to set these variables back to 0 _before_ you call any
rrd_* function in your program.
Final code snippet:
So finally your update of a rrd-database from your C program would look like:
[... snipp ...]
/* Code that fills rrd_argv and sets rrd_argc to the correct values */
optind=0;opterr=0;
rrd_clear_error();
rrd_ret=rrd_update(rrd_argc,rrd_argv);
if (rrd_test_error()!=0)
{
/* Handle error condition */
}
[... snipp ...]
Easy, isn't it?
Hope that helps.
Andreas.
P.S.: Same procedure applies to
rrd_create,rrd_restore,rrd_dump,rrd_tune,rrd_last and rrd_resize

[rrd-users] Bug? : RRDs perl module is very picky about trailing white spaces
Hello *! Monitoring hundreds of nodes with the help of rrdtool is fun and so I decided it is time to upgrade from 1.0.49 to 1.2.11. Everything worked well (compiled from the source tarball) but my perl script to produce nifty pictures now starts complaining about numerous errors. Checking the script and it seems that the perl module RRDs bundled with the new version is _really_ picky about trailing white spaces in DEF and CDEF statements. E.g. DEF:load15=$DataDir./.$host./load.rrd:load15:AVERAGE gives: Error:Cannot parse CF in 'DEF:load15=/home/www/systems/node064/load.rrd:load15:AVERAGE ' or CDEF:lw=up,idlecpu,+ results in: Error:invalid rpn expression in: up,idlecpu,+ Hmmm ... I guess trailing spaces in _these_ statements will produce no confusion (and with rrdtool 1.2.11 (1.2.x?) this whitespace is not considered as an error). Furthermore it now starts complaining about statements like this: COMMENT:Maximum: this produces this error: Error:Garbage ': ' after command: COMMENT:Maximum: Similar entries in AREA statements will produce: (e.g. AREA:procurfport16in#00ff00:Incoming traffic: ) Garbage found where STACK expected But this could be solved by escaping the colon like this: AREA:procurfport16in#00ff00:Incoming traffic\\: But this doesn't work with the errors generated by the COMMENT statement :/ Can I consider this behaviour as a bug? Or is it this the intended behaviour? Does anybody out there has a clue/workaround for this? Many thanks in advance, Andreas. P.S.: Have a nice weekend anyway ;) -- Dipl.-Ing.

That's because xport uses logic from the graph command where the step size is choosen based on the width of the graph. With the default maxrows value and your start and end values you get: 365 x 24 x 3,600 = 31,536,000 (seconds) 31,536,000 / 400 = 78,840 (step size) rounded to a multiple of 300 is 78900 Your are right. Running rrdtool xport with --maxrows -which can be calculated from a given start, stop and step- does the trick. PS: xport is available in the perl module (try the shared-demo.pl in the examples directory) Ooops. Missed that I was only looking through man 3 RRDs and didn't found an entry for RRDs::xport.

[rrd-users] A question regarding step size in rrdxport ...
Hello everybody. Perhaps someone out there can enlight me... :) I am collecting some statistics from several cluster nodes and store them in a rrd-database. Each database holds 216000 samples of 5 min (don't ask ... I really need this amount of data for such a long timespan ...). To generate some reports I tried to call rrdxport with a step size of 3600 sec. Running: rrdtool xport --start=-1year --end now --step 3600 DEF:node01=node01/load.rrd:load1:AVERAGE XPORT:node01:loadonnode01 But I get the expcted XML output with a step of 78900 seconds although the database is capable of handling this stepsize. Does anybody know how I get the desired step size of 3600 seconds via rrdxport? Many thanks in advance ... Andreas.

The name (and description in the man page) is a little bit misleading
(rrdxport - Export data in XML format based on data from one or several RRD)
You should use rrdtool dump and rrdtool restore to convert databases.
rrddump - dump the contents of an RRD to XML format
rrdrestore - restore the contents of an RRD from its XML dump format
So you should run:
rrdtool dump rrd_on_old_host.rrd rrd_on_old_host_dumped.xml
and restore them on the new host via:
rrdtool restore rrd_on_old_host_dumped.xml rrd_on_new_host.rrd
Easy, isn't it? ;)

Andreas.

I tried the following: int ret; char *cmd_update[5]; cmd_update[0] = update; cmd_update[1] = fic.rrd; cmd_update[2] = --template; cmd_update[3] = DSName; cmd_update[4] = 1067264490:1280; Is cmd_update[5] === NULL ? If I recall correctly the rrd_* functions parse the input with getopt and if you give options on the command line the argv array is NULL terminated at argv[argc]. Another pitfall is caused by the fact that getopt uses the optind variable and this variable is global ! So you have to reset optind before each call to rrd_*() It's a simple optind=0 but its annoying... Hope this helps...Andreas. P.S.: Hmmm... Maybe I will write a small documentation of the rrdtool-API. -- Dipl.-Ing.

I guess it worked before, because the memory area at cmd_update[5] was set to NULL by your system. Perhaps you calloc()ed it? Anyway. Adding the NULL pointer at the end doesn't cost a lot and is easy. I found out another strange thing: before a call to rrd_update I print my command line: for ( i = 0; i 5; i++) printf(%s ,cmd_update[i]); and I have on the screen: update fic.rrd --template DSName 1067264490:5.50 and that's correct Then I call: rrd_update(5,cmd_update); And, just after, print my command line one more time with the same instructions, and I have: update --template DSName fic.rrd 1067264490:5.50 Parameter 2 (fic.rrd) is now in 4th position ! ! ! ! ! Don't worry. The position doesn't matter. Do you have an explanation for that?? I guess it is the getopt_long call inside the rrd_*() call that changes the order of the arguments. It's nothing I would worry about. Thank you for your help Nevermind. So long ... Andreas. -- Dipl.-Ing.

[rrd-users] No int rrd_info(int,char**); in rrd.h ?
Hi everybody!
I use the C lib from the rrdtool (version 1.0.37) and a simple question arose
...
Why is there no definition of the rrd_info function
(and struct info_t, enum info_type and union infoval) in the
rrd.h file?
The function is defined in librrd.{a,so} and exists since version 1.0.17
(rrd.h since 1.0.22) -- so says the CHANGES file.
So is there a special reason not to include this
function in rrd.h? (But in the rrd_tool.h from the sources)
Many thanks in advance,
Andreas.

Nope. There are no errors, only warnings. You can ignore this. It happens on all my linux boxen, I ignored all of them and everything works fine... :) Am wondering if this is common and should be forgotten, or if this is the reason why Cricket isn't working properly :) I don't know...I don't use cricket...

[rrd-users] Accessing a rrd-database using C?
Hi!
I want to update my RRDs using C.
So I guess, I have to includ rrd.h and link the program against the
librrd. Right?
But if I try to compile the program gcc says:
[EMAIL PROTECTED]:~/code/c/rrd:gcc -o rrdtest -L/usr/local/rrdtool/lib
-I/usr/local/rrdtool/include rrdtest.c -lrrd
/usr/local/rrdtool/include/rrd.h:60: parse error before `*'
Hmmm...Whats the problem?
Line 60 in rrd.h is:
int LockRRD(FILE *);
So this shouldn't be a problem...
The problem I try to compile (rrdtest.c) is:
#include rrd.h
int main (int argc,char** argv)
{
int i=rrd_update(argc,argv);
return 0;
}
(Yeah, I know it is silly, but its just a test.)
Is there anyone out there who can give me a hint how to get rid of this
problem?
Thanks in advance...Andreas.
