As of now I am familiar with creating a chart using rrdtool. I just wanted to know whether there is any option in rrdtool to draw a drill down chart, i.e., if I select some region between 2 hour values, then the selected region should zoom and show the chart dividing the selected region into minutes, further if I select 2 minute values then it should show the graph divided into seconds between the 2 minutes. Is this possible to achieve this in rrdtool? If so can you please give me some idea?

The manual pages warn for this, but apparently nobody noticed the problem when the user asked for help. I admit that I did not immediately spot it and needed to do some debugging before being able to solve the problem. (see the rrd-users mailing list) Maybe rrdtool should refuse to use, or at least warn about, vnames which are also existing operators in RPN? cheers, Alex P.S. No, I cannot send a patch due to circumstances. </pre> Alex van den Bogaerdt 2013-02-21T21:30:08 http://comments.gmane.org/gmane.comp.db.rrdtool.devel/4285 <pre>Hey friends, I have added cassandra support to rrd like lidbi.

I spent the last few weeks testing libdbi support in rrdtool. Some people already reported that using libdbi is not very efficient, but I couldn't find any numbers on this (just "it's slow"). I've done some investigation, to track where performance was hit and on which criteria. This is of course when you want rrdtool graph, as data creation / updates are handled outside rrdtool. When using rrdtool file for storing data, it took the same time to graph 1 hour of data or 200 hours. Retrieving data from 1 DS or 5 DS (inside the very same rrd file) took approximately the same time. When using libdbi (with mysql backend), time needed to render the graph is skyrocketing, based on how many hours of data you want, and how many DS you have. The following chart is very straightforward : http://www.olivierdoucet.info/blog/wp-content/uploads/2012/12/graph.png What is interesting here is that time is not spent on the query itself (took less than a second, even for 1 year of data)</pre> Olivier Doucet 2013-01-07T16:52:13 http://comments.gmane.org/gmane.comp.db.rrdtool.devel/4276 <pre>I've just installed rrdcached and I'm checking its performance. I found that daemon does not sanitize file paths. Two different cliens may want to refer the same unix file with different names but rrdcached does not recognizes this but uses given filenames literally. E.g. Unix system calls "know" that the following files are the same /var/lib/cricket/subdir/foo.rrd and /var/lib/cricket//subdir/foo.rrd, /var/lib/cricket/subdir/bar.rrd and /var/lib/cricket/./subdir/bar.rrd etc. Meanwhile rrdcache thinks they are different. This may be problem when one program updates RRD file and an other one tries to flush cache before graphing. Checking the source code I found that severeal request handlers call get_abs_path(&amp;file, file_tmp), but then no one uses the content of file_tmp. Maybe this function could be replaced with an other that canonifies file paths. I.e. multiple slashes should be replaced with single one and "./" should be omitted.

The extension will provide a RRD data type which represents a complete database and functions for all the existing functions of the RRD tool, like create, update, first and graph... PostgreSQL has a nice API for LOB, which allows to store the whole RRD database using the PostgreSQL file management. I already have taken a look to the RRD code. As far as I can see, there are functions like rrd_create_r(...) which provides the functionality I need for such an extension. The PostgreSQL LOB API currently provides a file descriptor for the access to the data stored in the LOB. Unfortunately, it looks like the RRD API only allows the usage of a filename. Is there any way to use a file descriptor instead of the filename? Or is there any chance such a patch would be accepted? thanks Dustin Frisch </pre> Dustin Fisch 2012-09-08T20:44:49 http://comments.gmane.org/gmane.comp.db.rrdtool.devel/4250 <pre>Hi everyone, Recently I have experimented with dynamic graphing of RRDtool data on web pages (as JSON data queried by jQuery). While the JSON export and transport worked fine, after some testing I realized that starting with version 1.4 jQuery rejects JSON data which it thinks is malformed. When directly fed the output output of "rrdtool xport --json" jQuery barfs with an syntax error. Of course there are workarounds, but the attached fix is pretty trivial: Only the double quotes were missing in most of the JSON output from RRDtool to pass the jQuery test. The JSON standard is pretty strict on strings and requires any string to be wrapped in double quotes: http://json.org/ Personally I have also tested the resulting output with http://jsonlint.org/ and http://www.jsoneditoronline.org/ which both worked for me. YMMV, though.

This new script will merge one or more RRD files, which do not need to have the same DS or RRA definitions, to make a single RRD. It can preserve a configurable list of DS over the set, building different RRA from whichever available RRA match the closest, merging RRA where they cover different time windows. You can specify longer or shorter RRA length, and even change the step value as you go (though this is not yet working quite right). It should also be able to use one RRD to fill in the gaps in another, though this is still work in progress. It doesn't seem to work with HW RRAs yet, and I haven't tested with calculated DSs. Is there anyone out there who'd like to have a copy for testing purposes, and feed back patches/requests/bugs? The motivation for this script is to migrate our MRTG system (32bit, multiple archived copies of RRDs) to our new system (64bit, single extra-long RRD) but </pre> Steve Shipway 2012-08-20T00:53:08 http://comments.gmane.org/gmane.comp.db.rrdtool.devel/4231 <pre>Hi! So far the cooperation has been perfect, so I'm gonna dig deeper :-) OpenBSD has a modified toolchain that (among other cool features) warns you about certain programming constructs that have been found unsafe, like the use of strcpy/strcat/sprintf with non-const strings where the length isn't either known or properly estimated. To get rid of such warnings, I replaced the calls with strndup/strncat or snprintf. The OpenBSD variants strlcpy/strlcat aren't present in GNU libc and aren't likely to appear there because of Ulrich Drepper. My recent observations regarding portability: - Windows have _snprintf() defined in stdio.h. Does autocrap pick it up? - if there's a system without snprintf(), it can be easily replaced by dropping the second parameter, like so: #define snprintf(a, b, ...) sprintf(a, __VA_ARGS__) - I found just one #ifdef HAVE_SNPRINTF, but snprintf's already exist without being ifdef'd, which probably means people finally have this function on their systems and we can safel</pre> Martin Pelikan 2012-08-12T23:07:44 http://comments.gmane.org/gmane.comp.db.rrdtool.devel/4225 <pre>Hi!

However, there are a few dependencies that ruin our plan, most notably libxml2 and libglib. Even a minimal build (--disable-*) still has these dependencies. What we need is just to create and update RRDs. All graphing is interactive and handled in the web GUI. I have also seen similar needs expressed regarding restricted environments. The rrdupdate standalone utility is a good start, but it lacks the ability to create RRDs. The proposed patch (attached) adds two features to rrdupdate: info and create. This is done by invoking the binary with different names (ala BusyBox). For this, two symbolic links, rrdcreate and rrdinfo, are used. The size of a stripped rrdupdate is increased from 80kB to 88kB (libc on i386), but that is a small sacrifice compared with rrdtool + dependencies (minimal build &gt;2.0MB).

I have tried to make use of rrdjig.pl, but it ran for ages at 100%CPU and never finished on my test data. So I started writing a script that is able to extract the data from an original file and produces a list of update lines (takes from the "closest available resolution" - so if we have data for step 300, we take this, if not go to the next-higher version - up to 86400) - the timestamp is EXACTLY at the step boundry. This output is then fed into a new program that does the updates on an EMPTY rrd file with different RRA definitions (different number of rows and different pdp_per_step). But when I apply this update to the new empty rrd of the SAME definition i see: a) the data at step 300 is identical b) but the consolidated data at lower resolutions (say 86400) is not identical. So after heavy debugging I had found out that a lookup of the value in a Specific RRA for a specific Timestamp TS requires the following logic: For the timestamp TS I want to Insert (assuming TS % &lt;STEP&gt;=0), I have to loo</pre> Martin Sperl 2012-07-16T13:24:54 http://comments.gmane.org/gmane.comp.db.rrdtool.devel/4218 <pre>Hello, I am researching rrd-[developers|users] archives whether someone have done the extension of the RRD tool for milliseconds/sub-second stepping (e.g., --step 500ms) in the past? To date I found some mail threads with references to the subject but without an explicit success mark. Using this sub-second extension, I want to research mechanical gearboxes installed on remote sites in the field collecting the analogue data from gearbox' sensors in an RRA over 1 year via site local network. A gearbox aggregate has something like 150 data sources. (~50) of them need to be recorded with 100ms step. The system, I have in mind should work off-line/autonomously.
