rrddefinitons.cfg - how to modify the default step in RRA

Hi

I need to do a temporarily graph with a very low frequency : 5 seconds instead of the regular 300 seconds.

1/ On client side, the external script is simple:

[ buda ext]# cat httpd_threads.sh 
#!/bin/bash
THREADS_HTTP=`ps -ef | grep -c [h]ttpd`
LINE="data $MACHINE.trends
[httpd_threads.rrd]
DS:threads:GAUGE:5:U:U $THREADS_HTTP"
$BB $BBDISP "$LINE"

So, as you can see, the step is 5 in the DS.

clientlaunch.cfg has "INTERVAL 5s".

2/ On Xymon server side : 

rrddefinitions.cfg  :

# step = 5 seconds
[httpd_threads/5]
        # 576 * 60 * 5 sec = 48 h soit 2 jours sans perte
        RRA:AVERAGE:0.5:60:576
        RRA:AVERAGE:0.5:360:576
        RRA:AVERAGE:0.5:1440:576
        RRA:AVERAGE:0.5:17280:576


# This one is the default setup. You can change it, if you like.
[]
        # 576 datapoints w/ 5 minute interval = 48 hours @ 5 min avg.
        RRA:AVERAGE:0.5:1:576
        # 576 datapoints w/ 6*5 minute averaged = 12 days @ 30 min avg.
        RRA:AVERAGE:0.5:6:576
        # 576 datapoints w/ 24*5 minute averaged = 48 days @ 2 hour avg.
        RRA:AVERAGE:0.5:24:576
        # 576 datapoints w/ 288*5 minute averaged = 576 days @ 1 day avg.
        RRA:AVERAGE:0.5:288:576


3/ RRD created:

here the issue, the step is still 300. The minimal_heartbeat is 5.

rrdtool dump httpd_threads.rrd


<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE rrd SYSTEM "http://oss.oetiker.ch/rrdtool/rrdtool.dtd">;
<!-- Round Robin Database Dump -->
<rrd>
        <version>0003</version>
        <step>300</step> <!-- Seconds -->
        <lastupdate>1360264485</lastupdate> <!-- 2013-02-07 20:14:45 CET -->

        <ds>
                <name> threads </name>
                <type> GAUGE </type>
                <minimal_heartbeat>5</minimal_heartbeat

--- snip ---


How can i change the step to 5 instead of 300 ?

Thanks for your help.

The 5 in your DS is your heartbeat, not step.

Put a -s parameter in rrddefinitions.cfg  ie:

[httpd_treads/5]
     -s 5
RRA:AVERAGE:0.5:60:576
        RRA:AVERAGE:0.5:360:576
        RRA:AVERAGE:0.5:1440:576
        RRA:AVERAGE:0.5:17280:576


This will change your step to 5 seconds.  Note, that you will probably want to change your heartbeat to a value greater than your step.  By setting your heartbeat = step, you are running a probable scenario of missing data.  Your heartbeat should be greater than your step, I'd recommend double, if not triple.

Both step and heartbeat are set when the rrd file is created, you cannot change them on the fly.  If you do not wish to lose existing data, you will need to run "rrdtool tune -h threads:10" to change your heartbeat.   Then, you will need to dump your rrd to a file, edit the xml step with a text editor, then restore your rrd from the edited xml,

rrdtool dump httpd_threads.rrd > threads.xml
edit the threads.xml setting step to 5
rrdtool restore threads.xml httpd_threads.rrd

If you plan on doing this on several hosts, or plan on doing it frequently, I suggest you write a script and utilize the xymon grep utility.... it will make your life considerably easier.

Hi

Thanks for answer.

I updated the rrddefinitons.cfg with your recommandations :


[httpd_threads/15]
        -s 5
        RRA:AVERAGE:0.5:60:576
        RRA:AVERAGE:0.5:360:576
        RRA:AVERAGE:0.5:1440:576
        RRA:AVERAGE:0.5:17280:576

Then i restarted xymon server (it is needed ? in doubt i did it).

I also deleted the previous RRD file to see how is created a fresh one after the modification:

        </ds>


Unfortunately, it is still a step of 300.

What did i miss ?

Thanks again.

Hi,

i tried "-s" trick and i also checked the man of rrdcreation which made a reference of your suggestion:

 --step|-s step (default: 300 seconds)
       Specifies the base interval in seconds with which data will be fed into the RRD.


i tried to add both in rrddefinitions.cfg :

[httpd_threads/15]
	--step 5
        RRA:AVERAGE:0.5:60:576
        RRA:AVERAGE:0.5:360:576
        RRA:AVERAGE:0.5:1440:576
        RRA:AVERAGE:0.5:17280:576

or 

[httpd_threads/15]
	- s 5
        RRA:AVERAGE:0.5:60:576
        RRA:AVERAGE:0.5:360:576
        RRA:AVERAGE:0.5:1440:576

the step is with the correct value.

why rrddefinitons.cfg is not taking care of "-s"  ? Did i miss something ?

I also deleted the previous RRD file to see how is created a fresh one after the modification:

Unfortunately, it is still a step of 300.

The 5 in your DS is your heartbeat, not step.

Put a -s parameter in rrddefinitions.cfg  ie:

[httpd_treads/5]
    -s 5
    RRA:AVERAGE:0.5:60:576
       RRA:AVERAGE:0.5:360:576
       RRA:AVERAGE:0.5:1440:576
       RRA:AVERAGE:0.5:17280:576


This will change your step to 5 seconds.  Note, that you will probably want to change your heartbeat to a value greater than your step.  By setting your heartbeat = step, you are running a probable scenario of missing data.  Your heartbeat should be greater than your step, I'd recommend double, if not triple.

Both step and heartbeat are set when the rrd file is created, you cannot change them on the fly.  If you do not wish to lose existing data, you will need to run "rrdtool tune -h threads:10" to change your heartbeat.   Then, you will need to dump your rrd to a file, edit the xml step with a text editor, then restore your rrd from the edited xml,

rrdtool dump httpd_threads.rrd > threads.xml
edit the threads.xml setting step to 5
rrdtool restore threads.xml httpd_threads.rrd

If you plan on doing this on several hosts, or plan on doing it frequently, I suggest you write a script and utilize the xymon grep utility.... it will make your life considerably easier.

I need to do a temporarily graph with a very low frequency : 5 seconds instead of the regular 300 seconds.

1/ On client side, the external script is simple:

clientlaunch.cfg has "INTERVAL 5s".

in your rrdef.cfg file, Is your key correct?  Is the column you are reporting really [httpd_threads/15]?  This key is what it matches against your column.  If your key is [httpd_threads/15] but the column is "httpd_threads" (without the "/15"), then the rrd will be created with the default "[]" definition.

 From the rrddef.cfg comments:
# Each section key is the column- or data-name reported from your
# client test. Typically this is "cpu", "memory", "tcp", or some
# custom test you have created.

In your original script:

▸ quoted from Nicolas Lienard

[ buda ext]# cat httpd_threads.sh
#!/bin/bash
THREADS_HTTP=`ps -ef | grep -c [h]ttpd`
*LINE="data $MACHINE.trends*
[httpd_threads.rrd]
DS:threads:GAUGE:5:U:U $THREADS_HTTP"
$BB $BBDISP "$LINE"


it appears that your  data name is "trends".  This is what xymon is trying to match in rrddef.cvf.  The key you should be using in rrddef.cfg.

[trends]
     -s 5
     RRA:AVERAGE:0.5:60:576
     RRA:AVERAGE:0.5:360:576
     RRA:AVERAGE:0.5:1440:576
     RRA:AVERAGE:0.5:17280:576

With that said, "trends" is already a column heading... I'm not sure that using it for your rrd key won't cause other problems in xymon.  Maybe change it to "httpd_threads"?

If that doesn't work, try putting the -s in the default section "[]", and see if that works.  You shouldn't leave it there as it will set all future graphs to a 5 second step, but it works there, then you know your problem is with your data name and key.

        -s 5
        RRA:AVERAGE:0.5:60:576
        RRA:AVERAGE:0.5:360:576
        RRA:AVERAGE:0.5:1440:576
        RRA:AVERAGE:0.5:17280:576

There is no column, the script is only posting RRD data.

[ buda ext]# cat httpd_threads.sh
#!/bin/bash
THREADS_HTTP=`ps -ef | grep -c [h]ttpd`
LINE="data $MACHINE.trends
[httpd_threads.rrd]
DS:threads:GAUGE:5:U:U $THREADS_HTTP"
$BB $BBDISP "$LINE"


Is it the issue ?

Cheers

in your rrdef.cfg file, Is your key correct?  Is the column you are reporting really [httpd_threads/15]?  This key is what it matches against your column.  If your key is [httpd_threads/15] but the column is "httpd_threads" (without the "/15"), then the rrd will be created with the default "[]" definition.

Hi,

i tried "-s" trick and i also checked the man of rrdcreation which made a reference of your suggestion:

 --step|-s step (default: 300 seconds)
       Specifies the base interval in seconds with which data will be fed into the RRD.


i tried to add both in rrddefinitions.cfg :

[httpd_threads/15]
--step 5
        RRA:AVERAGE:0.5:60:576
        RRA:AVERAGE:0.5:360:576
        RRA:AVERAGE:0.5:1440:576
        RRA:AVERAGE:0.5:17280:576

or


[httpd_threads/15]
- s 5
        RRA:AVERAGE:0.5:60:576
        RRA:AVERAGE:0.5:360:576
        RRA:AVERAGE:0.5:1440:576
        RRA:AVERAGE:0.5:17280:576

But it doesn't change anything, the RRD file is still created with 300.

What s wrong ?

Hi

Thanks for answer.

I updated the rrddefinitons.cfg with your recommandations :


[httpd_threads/15]
        -s 5
        RRA:AVERAGE:0.5:60:576
        RRA:AVERAGE:0.5:360:576
        RRA:AVERAGE:0.5:1440:576
        RRA:AVERAGE:0.5:17280:576

Then i restarted xymon server (it is needed ? in doubt i did it).

I also deleted the previous RRD file to see how is created a fresh one after the modification:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE rrd SYSTEM "http://oss.oetiker.ch/rrdtool/rrdtool.dtd">;
<!-- Round Robin Database Dump -->
<rrd>
<version>0003</version>
        <step>*300*</step> <!-- Seconds -->
<lastupdate>1360331300</lastupdate> <!-- 2013-02-08 14:48:20 CET -->

        <ds>
                <name> threads </name>
                <type> GAUGE </type>
<minimal_heartbeat>*5*</minimal_heartbeat>
<min>NaN</min>
<max>NaN</max>

                <!-- PDP Status -->
<last_ds>32</last_ds>
<value>3.1000000000e+03</value>
                <unknown_sec> 105 </unknown_sec>
        </ds>


Unfortunately, it is still a step of 300.

What did i miss ?

Thanks again.

The 5 in your DS is your heartbeat, not step.

Put a -s parameter in rrddefinitions.cfg  ie:

[httpd_treads/5]
    -s 5
RRA:AVERAGE:0.5:60:576
       RRA:AVERAGE:0.5:360:576
       RRA:AVERAGE:0.5:1440:576
RRA:AVERAGE:0.5:17280:576


This will change your step to 5 seconds.  Note, that you will probably want to change your heartbeat to a value greater than your step.  By setting your heartbeat = step, you are running a probable scenario of missing data. Your heartbeat should be greater than your step, I'd recommend double, if not triple.

Both step and heartbeat are set when the rrd file is created, you cannot change them on the fly.  If you do not wish to lose existing data, you will need to run "rrdtool tune -h threads:10" to change your heartbeat.   Then, you will need to dump your rrd to a file, edit the xml step with a text editor, then restore your rrd from the edited xml,

rrdtool dump httpd_threads.rrd > threads.xml
edit the threads.xml setting step to 5
rrdtool restore threads.xml httpd_threads.rrd

If you plan on doing this on several hosts, or plan on doing it frequently, I suggest you write a script and utilize the xymon grep utility.... it will make your life considerably easier.

Hi

I need to do a temporarily graph with a very low frequency : 5 seconds instead of the regular 300 seconds.

1/ On client side, the external script is simple:

[ buda ext]# cat httpd_threads.sh
#!/bin/bash
THREADS_HTTP=`ps -ef | grep -c [h]ttpd`
LINE="data $MACHINE.trends
[httpd_threads.rrd]
DS:threads:GAUGE:5:U:U $THREADS_HTTP"
$BB $BBDISP "$LINE"

So, as you can see, the step is 5 in the DS.

clientlaunch.cfg has "INTERVAL 5s".

2/ On Xymon server side :

rrddefinitions.cfg  :

# step = 5 seconds
[httpd_threads/5]
        # 576 * 60 * 5 sec = 48 h soit 2 jours sans perte
RRA:AVERAGE:0.5:60:576
RRA:AVERAGE:0.5:360:576
RRA:AVERAGE:0.5:1440:576
RRA:AVERAGE:0.5:17280:576


# This one is the default setup. You can change it, if you like.
[]
        # 576 datapoints w/ 5 minute interval = 48 hours @ 5 min avg.
RRA:AVERAGE:0.5:1:576
        # 576 datapoints w/ 6*5 minute averaged = 12 days @ 30 min avg.
RRA:AVERAGE:0.5:6:576
        # 576 datapoints w/ 24*5 minute averaged = 48 days @ 2 hour avg.
RRA:AVERAGE:0.5:24:576
        # 576 datapoints w/ 288*5 minute averaged = 576 days @ 1 day avg.
RRA:AVERAGE:0.5:288:576


3/ RRD created:

here the issue, the step is still 300. The minimal_heartbeat is 5.

rrdtool dump httpd_threads.rrd


<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE rrd SYSTEM "http://oss.oetiker.ch/rrdtool/rrdtool.dtd">;
<!-- Round Robin Database Dump -->
<rrd>
<version>0003</version>
        <step>*300*</step> <!-- Seconds -->
<lastupdate>1360264485</lastupdate> <!-- 2013-02-07 20:14:45 CET -->

        <ds>
                <name> threads </name>
                <type> GAUGE </type>
<minimal_heartbeat>5</minimal_heartbeat

--- snip ---


How can i change the step to 5 instead of 300 ?

Thanks for your help.

From the rrddef.cfg comments:
*# Each section key is the column- or data-name reported from your
# client test.* Typically this is "cpu", "memory", "tcp", or some
# custom test you have created.

In your original script:
[ buda ext]# cat httpd_threads.sh
#!/bin/bash
THREADS_HTTP=`ps -ef | grep -c [h]ttpd`
*LINE="data $MACHINE.trends*
[httpd_threads.rrd]
DS:threads:GAUGE:5:U:U $THREADS_HTTP"
$BB $BBDISP "$LINE"


it appears that your  data name is "trends".  This is what xymon is trying to match in rrddef.cvf.  The key you should be using in rrddef.cfg.

[trends]
    -s 5
    RRA:AVERAGE:0.5:60:576
    RRA:AVERAGE:0.5:360:576
    RRA:AVERAGE:0.5:1440:576
    RRA:AVERAGE:0.5:17280:576

With that said, "trends" is already a column heading... I'm not sure that using it for your rrd key won't cause other problems in xymon.  Maybe change it to "httpd_threads"?

If that doesn't work, try putting the -s in the default section "[]", and see if that works.  You shouldn't leave it there as it will set all future graphs to a 5 second step, but it works there, then you know your problem is with your data name and key.

Hi

I think you are right, issue is my graph are created with data/trends without any column.

I hope Henrik will provide a patch to handle this case :)

I found a thread on ML where Henrik replied about the step:

http://lists.xymon.com/archive/2011-November/033057.html


The default for RRD-files generated by Xymon is to get updates in 5 minute intervals. To fix this you should define the RRD in the "rrddefinitions.cfg" file and specify a different update interval. If you update it once every 15 minutes = 900 seconds, then you can copy most of the default setup in that file, and just change the interval. Like this: 

[sfap/900] 
RRA:AVERAGE:0.5:1:576  RRA:AVERAGE:0.5:6:576 RRA:AVERAGE:0.5:24:576 RRA:AVERAGE:0.5:288:576

So, it seems that the -s is replaced by [column/step] at the end.
Going to try with NCV method...
Thanks again.
Cheers
Nico

Below is a simple stanza entry that can be added to the xymon server's task.cfg file for executing the MAPE update process. Can thus do away with the cron entry in the MAPE installation notes and have MAPE updates tied directly with Xymon operation.

Just edit the "<path to xymon>" for your particular environment. May also want to consider changing the update interval from 1 minute to 5 minutes or whatever is being used for the xymon web updates.

This is for MAPE 1.4 - may not be correct for 1.4+.

[mape]
        ENVFILE <path to xymon>/client/etc/xymonclient.cfg
        NEEDS xymond
        CMD <path to xymon>/server/www/MAPE/bin/parse-config.pl
        LOGFILE $XYMONSERVERLOGS/mape.log
        INTERVAL 1m
