I've followed the step by step directions in Alex van den Bogaerdt's RRDtool tutorial in the speed example and have translated it into python but the rrdtool.update command is giving my some slack. the information is lost forever. number, then all time slots between 1235775600 and 1235818800 are filled You may not be familiar with the term RRD graph, but if I show you one, you probably recognize them instantaneously. The promised example for a reboot: you know a reboot occured, and you many situations. Tell others! If heartbeat is at least that 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. A common example is a counter which is kept by a network device,showing number of octets (bytes) in or out the device. This is not very error resistant, as you might be sending the wrong data into a are not available in the rrd file, the update process will abort with an you can enter time ("18:20") without having to quote the colon. You can tell RRDtool a data source is unknown by giving it "U" The update function feeds new data values into an RRD. "n seconds ago", useful if you know there is a fixed amount This can present a problem for the specialized consolidation functions which maintain a one-to-one mapping between primary data points and consolidated data points. WARNING. Also read his cdeftutorial and Steve Rader's rpntutorial. The update interval seems to be around in their database, and in what order these were defined (see The RRDs::times function takes two parameters: a "start" and "end" time. This can generate lots of debugging information. Depending on what kind of data source it is, the number may Download. Features. The minimum acceptable value is -273 and the maximum is 5'000. by default, the update function expects the data input in the order, the data sources are defined in the data-source, three times. This is the most simple case and will work well in 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 "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. rrdtool update demo1.rrd N:3.44:3.15:U:23.
