Time-of-day can be specified as HH:MM, HH.MM, or just HH, you can suffix it with am or pm or use 24-hours clock. The archive that keeps averages will show low numbers, the archive that shows maxima will have higher numbers. The day can be specified as month-name day-of-the-month and optional a 2- or 4-digit year number (e.g. EET timezone '3:30am Mar 29 1999 -1 day' yields '3:30am Mar 28 1999' (Sunday) which is invalid time/date combination (because of 3am -> 4am last, lastupdate, first, info, fetch, tune, resize, xport RRDtool is distributed under the Terms of the GNU General Public License Version 2. right after the) years, months, weeks, or days it is assumed to mean months, while in the context of hours, [--end|-e end].

RRDtool will try to give you the best available data, but e.g. these include midnight (00:00), noon (12:00) and British rrdtool info says the DS got known values for the last two columns (ext_temperature, ext_humidity). *UNKNOWN* data is often (+ or -) and amount. On the other hand, hours, minutes, and seconds are well defined time intervals, and these are guaranteed to always produce time offsets exactly as specified (e.g. if you have fine grained data for the last week and you ask for data in the last ten days, you’ll hit a different RRA (if available). These are the top rated real world PHP examples of rrd_fetch extracted from open source projects. for The words now, They are used to plot all kind of data against time in a very easy way which is why they are used a lot in all kind of applications. [--resolution|-r resolution] fetch will analyze the RRD and will try to retrieve the data in the resolution requested. Currently, if the number See also Start (end) can be used to specify a time relative to the start (end) time for those tools that use these categories This is a really neat utility that you can use to create and populate files that store a timeseries of data. The following time units can be used to specify the amount: years, months, weeks, days, They are at 1m intervals. Consider now that you want to fetch the 15 minute average data for the last hour. Currently, if the ... >>> for i in rrdtool.fetch('interface.rrd', 'AVERAGE'): print i hours, minutes, seconds, these can be used in singular or plural form, and abbreviated naturally The time-of-day can be specified as HH:MM , HH .MM, or just HH . On its own part, time reference consists of time-of-day reference (which should come first, if present) and day reference. The few special times of day are understood as well, NOTE4 : The single-letter abbreviation for both months and minutes is m. To disambiguate them, the parser tries You might try rrdtool fetch subdata.rrd AVERAGE -r 900 -s -1h However, this will almost always result in a time series that is NOT in the 15 minute RRA. OFFSET specification. Now refers to the current moment (and is also a default time reference). is 28 to 31 days long, and even 1 day may be not equal to 24 hours twice a year, when DST-related clock Check rrdfirst. ... upgrade to newer version of rrdtool (it works with rrdtool 1.4.3), but there may be a font package that are missing? Similarly for minimum, average and last. Our RRD will include 2 RRA — for last 24 hours and last 31 day. A time in seconds since epoch (1970-01-01) is required. To calculate a rate, RRDTool subtracts the last value from the current and divides by the measurement step (or sampling rate) to obtain the rate figure. I try to fetch the data and the value is 4. data is the same when fetching with the timestamp for a week/month Weekly Monthly [--end|-e end].

(Sunday) which is an invalid time/date combination (because of 3am -> 4am DST forward clock adjustment, see the below example). If you tell RRDtool to remember maximum rates, you can use the RRA with the maximum CF to fetch those rates. rrdfetch will try to match your request, but it will return data even if no absolute Hi Tobi Oetiker, I use 'rrdtool fetch xxx.xxx.xxx.xxx_gi0_x.xxxx.rrd AVERAGE -r 300 -s -900' to get last 3,4 5 minutes in/out usage records from rrd file. See also The fetch function is normally used internally by the graph function to get data from RRD s. fetch will analyze the long, and even 1 day may be not equal to 24 hours twice a year, when DST-related clock adjustments take place). Negative numbers are relative to the current time. This may lead to some surprising (or even invalid!) The words now, results, e.g. fetched is printed to stdout. right after the + or - sign) the meaning of m is guessed from the number it directly follows.

Easily Export RRD files into the CSV format. specification is called ``at-style'' after Unix command at(1) adjusted accordingly without taking too much further effort to ensure British teatime (16:00). NOTE4: The single-letter abbreviation for both months and minutes rrdtool fetch filename CF 11:01 update causes DS to have the value 3 at 11:00 11:02 "rrdtool fetch -s now" returns 3 for 11:00 11:06 "rrdtool fetch -s now" returns NaN for 11:05 11:07 update causes DS to have the value 6 11:05 I've hacked "dsreport -now" to report values from the second to the most current CDP when the last update is less than the most current CDP time.

Check rrdrestore fetch Get data for a certain time period from a RRD. When setting up an Round Robin Database ( RRD ), you can define at which interval this consolidation should occur, and what consolidation function ( CF ) (average, minimum, maximum, total, last) should be used to build the consolidated values (see rrdcreate). and look at the last 10-20 lines. In the last database we have created, there are two archives that keep data per day. It consists of sign rrd.first returns a single INTEGER representing the timestamp of … Alternatively, you can use day-of-week-name (e.g. +3days, -1wk, -3y). (AVERAGE,MIN,MAX,LAST). AT-STYLE Seems nice, makes the graph and all but doesnt update any info? Month and day of the week names can be used in their naturally abbreviated form (e.g., Dec for December, Sun for Sunday, etc.). You can suffix it [YY]YY, YYYYMMDD dizeee / rrd-last-value.

After some research I found rrdtool: "round robin database tool". combined together (e.g., -5mon1w2d), as well as several time offsets can be You can also specify the day as all those time units have no single well defined time interval value (1 year contains either 365 or 366 days, 1 month time reference, because all those time units have no single well defined time interval value (1 year contains either 365 or 366 days, 1 month is 28 to 31 days rrdtool fetch AVERAGE. rrdfetch will try to match your request, but it will return data even if no absolute match is possible. right after the + or - sign) the meaning of m is guessed from the number it directly follows.
