tag:old.nabble.com,2006:forum-792Nabble - RRDTool2009-11-23T21:20:05ZRRD is the Acronym for Round Robin Database. RRD is a system to store and display time-series data (i.e. network bandwidth, machine-room temperature, server load average). It stores the data in a very compact way that will not expand over time, and it can create beautiful graphs. It can be used via simple shell scripts or as a perl module.

<br><br>This is to chart a number once a day.
<br><br>At the end of my backup script, if the rrd does not exist, it is created

<br> "RRA:LAST:0.5:1:365" \
<br> "RRA:LAST:0.5:30:60"

<br> with a Data Store named='size',
<br> of type type=GUAGE,
<br> and if it isn't updated every 87000 seconds (a little over 24 hours),
<br> the recorded value will be 'unknown' (this is the heartbeat).
<br> Only half the members of each RRA need to be present, or value will be 'unknown'.
<br> The first RRA uses 1 PDP and stores 365 records (for a 1 year period tracked).
<br>The second RRA uses 30 PDP and stores 60 records (for a 5 year period tracked).
<br><br>After this step, I try to add the size of the backup with the following
<br>command:
<br> rrdtool update "${RRD_File}" "N:${size}"
<br><br>The script log shows that the two variables ${RRD_File} and ${size} are

<br><br>I set the heartbeat to 87000 seconds (slightly higher than the step of
<br>86400 seconds) to allow extra time for the backup to complete.
<br><br>After the update, when I do a dump, nothing is stored in either rra.

</div><br>\n is not realy a valid choice (it is only accepted for backward

<br>font you have to use \t for alignment ... which you don't seem to

<br><br>In my monitoring application I'm using --template for all RRD updates.
<br>Now I'm planning(forced) to use rrdcached for scaling/performance
<br>reasons and noticed that it doesn't support the template switch together
<br>with --daemon :
<br><br> Error message:
<br> "The caching daemon cannot be used together with templates yet."
<br><br>I was checking all my different types of rrd files if the order of
<br>Datasources is consistent between them. Unfortunately they aren't due
<br>to historical reasons ;-( , they all have the same Datasources in it
<br>but not in the same order.
<br><br>Now my questions:
<br><br>1.) is it possible to modify the order of Datasources in a rrd file
<br> without export/xml-fidling/restore ?
<br> Nothing found in manpage of rrdtune.
<br><br>2.) I haven't yet looked into rrdcached sources but supporting the
<br> template switch with the daemon sounds challenging.
<br> Otherwise the "not yet" in the error message promises the feature
<br> to be implemented in the near future .... does it ? ;-)
<br><br><br>thx in advance for any feedback
<br>regards, wolfgang

</div><br>rrdtool stores data in a rotating buffer. the last (latest) value
<br>in the buffer coresponds to the last time you update it. As you
<br>create a new rrd you can define when it should expect the 'first'
<br>input using the --start parameter (maybe oddly named). As you
<br>create a new rrd file it stretches into the past fro the current
<br>time or whatever you defined using --start
<br><br>as you are filling the rrd with data it rolls forward, dropping off
<br>the values stored at the end of the archive. hence the name ...
<br>round robin ....

<br><br>Yes. Use 'graphv' instead of 'graph', and it returns details about the

<br>graph twice. Once to get the times, then again after you have that
<br>information.

<br><br>No. I might want to see a week's worth or a month's worth or whatever range

<br>For instance how much electricity did I use in august, or how much AC did I

<br><br>The spec file is from an older version and I did do some modifications to it, to fit my environment/EL4.
<br><br>As we don't care about ruby, tcl, php or python I used this command to build:
<br><br>rpmbuild -bb --define '_without_python 0' --define '_without_php 0' --define '_without_tcl 0' --define '_without_ruby 0' rrdtool.spec
<br><br>I am now proceeding with a test of building collectd 4.8.1 and to use it to send data to a central server, which will run rrdcached.

<br>> Ok, I will patch out the check for it in configure.ac for now
<br><br>I do not see an option to specific not rrd_daemon, so after removing the glib check in configure.ac, I added still CPPFLAGS to the configure for it to find the include files of the older glib 2.4.17, as otherwise the compile of rrd_daemon.c complains about all the glib includes.
<br><br>This results still into two errors:

<br><br>This is on the 1.4.2 code, line 822 is:

<br><br>Line 1271 is:

<br><br>In version 2.4.17 g_tree_remove returns void, in version 2.8 and later this changes to Boolean. Function is used once to assert, I think I can just patch that out to not check for TRUE and assert. But the other location at 1271 wants to do something based on the return. Any suggestion if I can patch out the journal_write?
