[rrd-users] Numeric output only
Hello, In order to create some nice reports i need to be able te generate text only output, this can be done using PRINT however a unused graph i still generated at that time (which costs CPU power). Is it possible to only generate txt output?

Just realised i had some AREA's still defined, if you define no output (line/area/gprints) the image won't be generated (size 0x0) Erik wrote: Hello, In order to create some nice reports i need to be able te generate text only output, this can be done using PRINT however a unused graph i still generated at that time (which costs CPU power).

Hi all, using RRD Tool and Routers 2 to display my graphs. I get the following error RRD Error: Garbage ':46:00 AM\r' after command: COMMENT:11/18/2005 7:46:00 AM\r on all of my targets. I searched the WEB and have not found anything, has anyone seen this before?

Hi Miachael. Hi all, using RRD Tool and Routers 2 to display my graphs. I get the following error RRD Error: Garbage ':46:00 AM\r' after command: COMMENT:11/18/2005 7:46:00 AM\r on all of my targets. I searched the WEB and have not found anything, has anyone seen this before? Which version of rrdtool do you use? I guess you are using rrdtool 1.2.x?. In version 1.2.x you _have to_ esacpe _all_ colons. See the NEWS file and look in the section called Incompatibilities: [... snipp ...] * Colons in COMMENT arguments to rrdtool graph must be escaped with a backslash [... snipp ...] HTH, Andreas. -- Dipl.-Ing.

[rrd-users] Performance problem updating many RRD files
Hi, I'm using RRDTool to store data series produces by flowscan/JKFlow and I hit a performance problem updating many files. With 256 Mb RAM caching works OK up to about 2000 RRDs, but after that # performance fall suddenly. About 180Mb of RAM are dedicated to file caching, and I imagen that at certain amount of rrd files the caching system start to drop based on some LRU algorithm and the windows of caching just run useless behind the secuential update done on rrd files. Initially I was using RRDTool 1.0.49 and now I changed to 1.2.11 hoping MMAP IO would help with this. I made sure I compiled it with --enable-mmap but there was no diference in the # of files where performance degrades. I did not find any detail in how does MMAP works in the web, docs, neither have enough programming knoledge to understand the code, so I would apreciate if someone can give me information on: *The process of updating rrd files: I thought it was just needed to read/write a few bytes in every file, but it seems it is necesary to load a considerable part of the file in the cache in order to update it. *How MMAP IO works and how I use it: I imagen writing the updates of many files in memory and then sending all the request together to the disk, letting it to be more efficient. I didn't see any reference in rrdupdate doc on how to indicate how to use mmap. One quick solutions seem to be adding RAM, but I just want to do this as efficient as possible.

With 256 Mb RAM caching works OK up to about 2000 RRDs, but after that # performance fall suddenly. About 180Mb of RAM yes rrdtool update performance is 'cache bound' ... I don't think MMAP will help with this ... MMAP will make updating faster but the difference is nowhere as large as what the cache does for you ... add more memory and you can update more rrd files fast ... cheers tobi -- ____ _ /_ __/_ / / (_) Oetiker @ ISG.EE, ETL F24.2, ETH, CH-8092 Zurich / // _ \/ _ \/ / System Manager, Time Lord, Coder, Designer, Coach /_/ \.__/_.__/_/ http://people.ee.ethz.ch/oetiker +41(0)44-632-5286 -- Unsubscribe mailto:[EMAIL PROTECTED] Helpmailto:[EMAIL PROTECTED] Archive http://lists.ee.ethz.ch/rrd-users WebAdminhttp://lists.ee.ethz.ch/lsg2.cgi

[rrd-users] Plot a dotted line
Hi all, is there a way to display a dotted line on a graph? I have to display an estimated value, so I thought a dotted line would be better... Thanks in advance, Simone. -- Unsubscribe mailto:[EMAIL PROTECTED] Helpmailto:[EMAIL PROTECTED] Archive http://lists.ee.ethz.ch/rrd-users WebAdminhttp://lists.ee.ethz.ch/lsg2.cgi

You want an intermittent on/off pattern, so you need to find a CDEF that alternates between UNKN and your value. The necessary CDEF will depend on the amount of time in your graph. For instance: if the graph displays 400 hours, you could display that value for each odd hour and NaN for each even hour. something like (untested!): CDEF:dotted=TIME,3600,/,2,%,value,UNKN,IF -- Alex van den Bogaerdt http://www.vandenbogaerdt.nl/rrdtool/ -- Unsubscribe mailto:[EMAIL PROTECTED] Helpmailto:[EMAIL PROTECTED] Archive http://lists.ee.ethz.ch/rrd-users WebAdminhttp://lists.ee.ethz.ch/lsg2.cgi
