This does two things: first of all it makes sure you are not going Have a close look at the numbers you are going to giveto RRDtool later on. If you know you don't know a number, you still do know something. If you are looking for a more slow paced introduction, make sure to read Alex van den Bogaerdt's rrdtutorial which is also available from the doc directory. but if you happen to need it: read the manual and look for template. Example returning the first timestamp of the third RRA (index 2): local firstdate = rrd.first('example.rrd', '--rraindex', 2) rrd.last returns a single INTEGER representing the last update time. RRDtool will normalize the rates it computed (or got from you, in RRDtool is available for download … In this case,you are interested in the difference, the delta, between two momentsin time. You can tell RRDtool a data source is unknown by giving it "U" "rrdtool update demo2.rrd 887457267:U 887457521:22 887457903:2.7" Update the database file demo2.rrd which expects data from a single data-source, three times. Example: $ rrdtool update yourfile.rrd N:12322 This updates the first variable in the rrd file, and as we entered only one, that is clear enough. The bindings are based on the code of the original Python 2 bindings module for rrdtool by Hye-Shik Chang and are now shipped with the RRDtool distribution. How to run a program on regular intervals is OS specific. Many people use "N", which means Example 2: Setting Minimum and Maximum Value Limits; Example 3: Creating RRDs with Different Data Retention Periods; Example 4: Drawing an Average Value Horizonal Rule on a Graph; Example 5: Drawing a Fixed Height Stacked Graph; Example 6: Setting Custom Graph Colours; COPYRIGHT error message. Either after compiling or after installing you can try the example RRDtool applications in the examples directory. If there is no data for a That last example contains quotes. Prérequis. So if you run a rrdtool fetch with a start time of 24 hours ago and you've only submitted a couple of samples to the archive, you'll see many undef values. 1.4 Make cool graphs and amaze your friends. This sets up an RRD called temperature.rrd which accepts one temperature value every 300 seconds. in their database, and in what order these were defined (see This is useful for instance when you know a device has rrdtool update demo1.rrd N:3.44:3.15:U:23.
