If a graph insists on viewing the contents of these ...

    RRDtool grading graphs – Alex' Blog

    One thought on “ RRDtool grading graphs ” Dave Schmid 2019-09-19. Alex – thank you for your scripts. I was looking for a way to dump in per-second data into a ping script for RRD and this was exactly what I was looking for (with a few modifications.) With newer versions of RRDtool – gradients come built in… So I updated to just be: this is a bit tricky, since we're dealing with RPN then we're going to make use the 'PUSH' and 'POP' command. What we're trying to do is to multiply every single data with the "a" as described in the least square to simulate a linear function which can only be done with the 'COUNT' function.However, there is a question on how we manipulate the data without having to modify the data itself.

    rrd - rrdtool print (not graph) on same lines? - Stack ...

    No, you cannot do this, as the PRINT directive does not work this way.. While the GPRINT directive allows you to use \l, \r, \c for starting a new line and specifying justification options, the PRINT statement defines a single string. Each of the strings (IE, each PRINT directive) constitutes a new item in the output array, which is printed with one item per line.

By default, rrdtool graph calculates the width of one pixel in the time domain and tries to get data from an RRA with that resolution. With the step option you can alter this behaviour. If you want rrdtool graph to get data at a one-hour resolution from the RRD, set step to 3'600. Note: a step smaller than one pixel will silently be ignored. Hello. In my templates pnp, I still have a problem of alignment in the graphic legend RRDTool. There are always spaces even with tabs. For example, here is what to do :

    rrdtool graph needs data to work with, so you must use one or more data definition statements to collect this data. You are not limited to one database, it's perfectly legal to collect data from two or more databases (one per statement, though).

When ever such a character occurs, all pending text is pushed onto the graph according to the character specified. This forum was archived to /woltlab and is now in read-only mode.

    RRDTOOL mini HOWTO : rrdtool

    This would lead to boring graphs, so rrdtool then plots the *difference* betweet a measurement and the previous one, divided by the elapsed time. If you enter 'ABSOLUTE', rrdtool will assume that the counter resets upon reading, and plots the value divided by the time since the previous measurement. * restore from a pipe (rrdtool restore - y.rrd) * in rrdtool create, row count and step can be defined in absolute time * all new "create on steroids" can pull both data and configuration from existing rrd files * use rrdtool graph to chart arbitrary data via a callback function for data fetching support is integrated in the perl bindings.
