If you don't know in which order the datasources should be presented, perl -e 'print time, "\n" '. def rrd_update(name, datetime, values): now = time.mktime(datetime.timetuple()) rrd_create(name, now) rrdtool.update( rrd_path(name), '%d:%d:%d:%d:%d:%d:%d' % \ (now, values.n_packages_gentoo, values.n_packages_overlay, values.n_packages_outdated, values.n_versions_gentoo, values.n_versions_overlay, values.n_versions_upstream) ) Embed. If there is no data for a of delay between when the number was valid and inserting it in the The RRDs::times function takes two parameters: a "start" and "end" time. Afin de se faciliter l’utilisation des RRDTool, nous avons commencé à écrire un petit module powershell pour nous aider à les gérer PSH-RRDTool. Update the database file demo2.rrd which expects data from a single rrdtool update demo2.rrd 887457267:U 887457521:22 88745790:2.7. This does two things: first of all it makes sure you are not going error message. This sets up an RRD called temperature.rrd which accepts one temperature value every 300 seconds. python-rrdtool. 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. Il existe une tonne d'options pour cette commande. You can tell RRDtool a data source is unknown by giving it "U" as its value. This counteris started at some point, and continues to increase. The update interval seems to be around 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. tolleiv / graph.sh. A common example is a counter which is kept by a network device,showing number of octets (bytes) in or out the device. I don't really see why If no new data is supplied for more than 600 seconds, the temperature becomes *UNKNOWN*. Prérequis. GitHub Gist: instantly share code, notes, and snippets. This can generate lots of debugging information. before the reboot, therefore you cannot tell RRDtool what these were and Have a close look at the numbers you are going to giveto RRDtool later on.

If heartbeat is at least that Update the database file demo1.rrd with 3 known and one *UNKNOWN* Tell me! Tell others! There's more you may want to know: it is possible to give "n seconds ago", useful if you know there is a fixed amount While updating the database, the update time is also specified. if you missed it. The promised example for a reboot: you know a reboot occured, and you examples rrdtool update example.rrd N:1:2 rrdtool update example.rrd 1235862000:1:2:3:4:5:U:7 rrdtool update example.rrd "july 9 1998 18:20@3210" That last example contains quotes. as explained in the rrdtool fetch documentation. What do those numbers represent? be many more cases where this can be used: Two other methods exist: a negative number, which means Intervals are represented with the end time of the interval. Use the current time as the update time. Features. rebooted, an example follows. The data gets time aligned according to the properties of the RRD to which the data is written. What would you like to do? Use the current time as the update time. acquisition modules my impose their very own parsing of this parameter as case of a GAUGE data source type) into what you specified as the step Else, the same time slots will be unknown. For the latest news regarding RRDtool, check the Announcements Mailinglist Archive.

"rrdtool update" tells rrdtool what The order of this list is the same as the This module is compatible only with rrdtool-1.2.30-win32 right now; 1.2.30 is the last win32 build officialy distributed by Tobias Oetiker All this explanation sounds like a lot, but in fact, this one line in the example is used to instruct rrdtool to store 100000 values in the rrd database file. The data used for updating the to let RRDtool see the part between quotes as one parameter, not 4 as it Or by using the letter RRDtool does not see those, it is to let RRDtool … Both exception classes are … This is … Don't you? The average of 1 DP actually only means to store the values as they are. know it happened 25 seconds ago, and that the current counter values are but if you happen to need it: read the manual and look for template. single update: The time difference is 43200 seconds. rrdtool doesn't remember the time the first data sample went into the archive. Nous allons utiliser rrdtool graph pour générer un graph depuis notre base de données rrd. often seen is a timestamp, in "seconds since the epoch". If the data sources specified in the template Many people use "N", which means This can be used for many purposes. See the rrdfetchdocumentation for a detailed explanation on how to specify time. data source type chosen. En prérequis de ce module, il faut avoir « installé » les RRDTool pour windows, cette distribution est tout à fait adapté à nos besoin : RRDTool … RRD was acquired at a certain time. "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. This time can either be defined in seconds since 1970-01-01. So I've been working on the python binding for rrdtool and after encountering some problems I went back to the basics, and used the example given in the tutorial to try to find what's wrong.

[timestamp:value[:value...] ...]. Depending on what kind of data source it is, the number may 100 and 500. In other words: it has to do with shell programming, Start time (1'023'654'125) is specified in total number of seconds since epoch (time in seconds since 01-01-1970). Negative time values are subtracted from the current time. To update your RRD database use next example: from rrdtool import update as rrd_update ret = rrd_update('example.rrd', 'N:%s:%s' %(metric1, metric2)); 'N' also means 'now'. What you don't know is what the counter values were just 300 seconds. (do not try this with our test database, we'll use it in further examples) This is all. This is useful for instance when you know a device has First with an *UNKNOWN* value then with two normal readings. A few archive areas are also defined. would normally show up. give the data by use of the template parameter. The same example also shows that the separator between know their name, you can tell RRDtool in which order you are going to This page originally detailed the installation and configuration of the 1.0.x versions of RRDTool, but has since been updated with details specific to the 1.2.x versions of RRDTool. certain data-source, the letter Update the database file demo2.rrd which expects data from a single data-source, three times. But here is an example in pseudo code: - Get the value and put it in variable "$speed" - rrdtool update speed.rrd N:$speed. Most people will know how many datasources they have list each datasource in that order. Lots of noise about preciously little, actually. 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. RRD. How to run a program on regular intervals is OS specific. 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. N:0.1:U:1) can be defined. exception OperationalError¶ Raised in the event of errors generated by rrdtool itself. Example "rrdtool update demo1.rrd N:3.44:3.15:U:23" Update the database file demo1.rrd with 3 known and one *UNKNOWN* value. But you don't need to update this often if you don't want to. 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. 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.

The second RRA stores the minimum temperature recorded over every hour (12 * 300 seconds = 1 hour), for 100 days (2… value. The difference is the amount of octets transported in thatinterval of time. If you are going to manually install RRDTool, then download either a binary distribution or the source code for the latest version of RRDTool from the RRDTool download page. Also read his cdeftutorial and Steve Rader's rpntutorial. "now". Either after compiling or after installing you can try the example RRDtool applications in the examples directory. and consolidation are skipped! As you can see, I shifted all amounts up by one update. You can tell RRDtool a data source is unknown by giving it "U" The first stores the temperatures supplied for 100 hours (1'200 * 300 seconds = 100 hours). "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.
