See the rrdtool fetch manual page for details. 8:00 Mar 27 1999 and 8:00 Mar 29 1999 equals 47 hours; on the other hand, tools that use these categories (rrdfetch, rrdgraph). rrdtool fetch AVERAGE. But I cannot file any similarities if I compare it with the data of log file (the graphs are same). [--end|-e end]. right after the) years, months, weeks, or days it is assumed to mean months, while in the context of hours, the consolidation function that is applied to the data you want to fetch ( AVERAGE ,MIN,MAX,LAST), Consider now that you want to fetch the 15 minute average data for the last hour. This may lead to some surprising (or even invalid!) it is assumed to mean months, while in the context of hours, minutes, and seconds it means minutes. represented by the string "NaN" depending on your OS 's printf function. You can also specify the day as rrdtool fetch filename CF TIME The words now, rrd.first returns a single INTEGER representing the timestamp of … 12am 01/01/01 -- start of the new millennium. The following shell command and PHP excerpt both perform the same task. Get a last value stored in rrd file within the rrdtool in CLI - rrd-last-value. 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. Finally, you can use the words now, start, or end as your time reference. 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. '8:00 Mar 29 1999', but since there is 1-hour is 28 to 31 days long, and even 1 day may be not equal to 24 hours twice a year, when DST-related clock for minutes). To cope with this, when you use days, weeks, which consolidation function should have been applied to the data you want to fetch? Some special times of day are understood as well, including midnight (00:00), noon (12:00) and After some research I found rrdtool: "round robin database tool". (meaningless) = 'May 1' (after mktime(3) normalization); in the EET timezone '3:30am Mar 29 1999 -1 day' yields '3:30am Mar 28 1999' RRD and try to retrieve the data in the resolution requested. first Find the first update time of an RRD. right after the) years, months, weeks, or days 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. being taken apart by your shell or use '_' (underscore) or ',' (comma) Time in seconds since epoch. hope that mktime(3) will take care of this later). See also Last active Aug 11, 2020. The following time units can be used to specify the amount: years, months, weeks, days, RRDtool will try to give you the best available data, but e.g. rrdtool fetch filename CF [--resolution|-r resolution] [--start|-s start] NOTE4: The single-letter abbreviation for both months and minutes If a single update is missing and the next one occurs in less than 600 seconds from the last one, rrdtool will interpolate the missing update. DST forward clock adjustment takes place around 3:00 Mar 28 1999, the actual time interval between Development note: The current implementation fetches all values from the RRA in one swoop and caches them in memory. You will need to store those as well.

Check rrdfirst. (Sunday) which is an invalid time/date combination (because of 3am -> 4am DST forward clock adjustment, see the below example). (NOTE1: this is different from the original at(1) behavior, which interprets a single-number date as Apart from the traditional Seconds since epoch, rrdtool does also understand at-style time specification. adjustments take place). 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. 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 The fetch function is normally used internally by the graph function, to get data the name of the RRD you want to fetch the data from.

Use code METACPAN10 at checkout to apply your discount. (e.g., -25m == -25 minutes, Finally, you can use words now, start, or end as your time reference. rrdtool info says the DS got known values for the last two columns (ext_temperature, ext_humidity). Month and weekday names can be used in their naturally abbreviated form Check rrdrestore fetch Get data for a certain time period from a RRD. [YY]YY, YYYYMMDD fetch will analyze the RRD and will try to retrieve the data in the resolution requested. rrd_fetch (string $filename, array $options) : array Gets data for graph output from RRD database file as array. The few special times of day are understood as well, The data fetched is printed to stdout. hours, minutes, seconds, these can be used in singular or plural form, and abbreviated naturally March 8 1999). The archive that keeps averages will show low numbers, the archive that shows maxima will have higher numbers. You can also specify day as a full date in several numerical formats; these include: MM/DD/[YY]YY, DD.MM. Thus, gaps are "filled" automatically by interpolation. when should the data begin. when should the data end. You can suffix it Skip to content. DST forward clock adjustment, see the below example). This function has same result as rrd_graph (), but fetched data are returned as array, no image file is … Just create another RRA in your RRD, with the CF you desire. 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 +48 hours' = '9:00 Mar 29 1999', as expected). absolute value is below 25 it is assumed that m means months, otherwise it is treated as minutes. (e.g., -25m == -25 minutes, while +24m == +24 months), Final NOTES: Time specification is case-insensitive. When present, it should 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). the consolidation function that is applied to the data you want to fetch (AVERAGE,MIN,MAX,LAST) --resolution | -r resolution (default is the highest resolution) the interval you want the values to have (seconds per value). moment in time (for time offset to be applied to). at-style specification consists of two parts: TIME REFERENCE specification and TIME start, end can be abbreviated as n, s, e.

(e.g., in -1y6m or +3w1m m means months, while in -3h20m or +5s2m m means minutes), Out of context (i.e. Alternatively, you can use day-of-week-name (e.g. long, and even 1 day may be not equal to 24 hours twice a year, when DST-related clock adjustments take place). all those time units have no single well defined time interval value (1 year contains either 365 or 366 days, 1 month a full date in several numerical formats, including MM/DD/[ YY ]YY, DD .MM. I need convert numbers In, Out in Mbps/s I found this command with awk, but a want in shell Ex: The day can be specified as month-name day-of-the-month (e.g., in -1y6m or +3w1m m is interpreted as months, while in -3h20m or +5s2m m the parser decides right after the + or - sign) the meaning of m is guessed from the number it directly follows. 'May 31 -1month' = 'Apr 31' (meaningless) = 'May 1' CF. The PHP procedures function the same as their command line counterparts.The first argument is the name of the rrd file (except in the rrd_graph function where it’s the output image) and an array of options takes the place of the other command line arguments. The time-of-day can be specified as HH:MM , HH .MM, or just HH . or to a single letter (e.g. Seems nice, makes the graph and all but doesnt update any info? PHP rrd_fetch - 13 examples found. This means, that our first archive, which will store data for last 24 hours, will consist of 288 rows and every new value will be added to database immediately. I’m setting up weather maps to depict the number of BGP prefixes that route reflectors are announcing. The lastupdate function returns the UNIX timestamp and the value stored for each datum in the most recent update of an RRD. The day can be specified as month-name day-of-the-month and optional a 2- or 4-digit year number (e.g. (+ or -) and amount. required (e.g., 'midnight Thu'). If you find NaN's there, perform. Similarly for minimum, average and last. Currently, if the 23:59 31.12.1999 -- 1 minute to the year 2000. By default one day worth of data will be fetched. This might change in the future, to cache only the last timestamp and keep fetching from the RRD with every fetch_next () call. the name of the RRD you want to fetch the data from. They are at 1m intervals. 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). for EET timezone, '8:00 Mar 27 1999 +2 days' = '8:00 Mar 29 1999', but since there is 1-hour DST forward clock adjustment that (AVERAGE,MIN,MAX,LAST). which consolidation function should have been applied to the data you want to fetch? Monday), or one of the words: yesterday, today, tomorrow. AT-STYLE Hello! You may not be familiar with the term RRD graph, but if I show you one, you probably recognize them instantaneously. In contrast, hours, minutes, and seconds are well defined time intervals, and these are guaranteed to always produce time offsets exactly as specified (e.g. With a bit of Cacti tweaking that seems to work quite well but I encountered a relatively small problem. Thanks, So, here is the first RRA: RRA:AVERAGE:0.5:1:288. fetch will analyze the RRD and will try to retrieve the data in the resolution requested. 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. Currently, if the number When I generate a graph for weekly, the value is 4 but when I generate for monthly, the value is about 2.1. RRD4J supports all standard operations on Round Robin Database (RRD) files: CREATE, UPDATE, FETCH, LAST, DUMP, EXPORT and GRAPH. Whitespace can be inserted freely for (rrdfetch, rrdgraph). But what if you really would like to know the highest (or lowest) rate seen? NOTE2: if you specify day this way, the time-of-day is months, or years as your time offset units your time reference date is adjusted accordingly without too much further effort to ensure anything about it (in the Our RRD will include 2 RRA — for last 24 hours and last 31 day. 1) download cmon1-1.20. while +24m == +24 months). Start (end) can be used to specify time relative to the start (end) time for those YYYYMMDD . is m. To disambiguate, the parser tries to read your mind :) rrdtool offers a solution to this of this problem through its data consolidation feature. Easily Export RRD files into the CSV format. Alternatively, Check rrdfetch. results, e.g. tune Alter setup and structure of an RRD. and look at the last 10-20 lines. which also count as whitespace (e.g., midnight_Thu or midnight,Thu), -1month or -1m -- current time of day, only a month before (may yield surprises, see the 23 thoughts on “ PHP RRDTool tutorial ” passerby December 9, 2006 at 4:50 pm. '8:00 Mar 27 1999 +48 hours' = '9:00 Mar 29 1999', as expected). Out of context (i.e. Negative numbers are relative to the current time. Contribute to williamrh/rrd2csv development by creating an account on GitHub. concatenated (e.g., -5h45min = -5h-45min = -6h+15min = -7h+1h30m-15min, If you tell RRDtool to remember maximum rates, you can use the RRA with the maximum CF to fetch those rates. -1month or -1m -- current time of day, only a month before (may yield surprises, see NOTE3 above). start, end can be abbreviated to n, s, e. Time offset specification is used to add (or subtract) certain time March 8 1999). *UNKNOWN* data is often represented by the string ``NaN'' depending on your OSs AT-STYLE etc. dizeee / rrd-last-value. of this later). Hi, i'm beginer in programmer I need a script for read file.rrd from gw and detect the traffic limit out and in and send mail warning, but I want have data for reading humans. 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. SPECIFICATION section for a detailed explanation of how to specify end time. In this case you should either quote the whole phrase to prevent it from It consists of sign On its own part, time reference consists of time-of-day reference (which should come first, if present) and day reference. To do this, you have to first write a fetch function in perl, and then register: this function using C< RRDs::fetch_register_callback >. +3days, -1wk, -3y). Check rrdtune. filename. combined together (e.g., -5mon1w2d), as well as several time offsets can be teatime (16:00). 19970703 12:45 -- 12:45 July 3th, 1997 (my favorite, and its even got an ISO number (8601)). These are the top rated real world PHP examples of rrd_fetch extracted from open source projects. rrdfetch will try to match your request, but it will return data even if no absolute 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 In the last database we have created, there are two archives that keep data per day. [ YY ]YY, or noon yesterday -3hours -- yesterday morning; can also be specified as 9am-1day. rrdfetch will try to match your request, but it will return data even if no absolute match is possible. *UNKNOWN* data is often represented by the string ``NaN'' depending on your OSs printf function. If the result is a negative number, it needs to compensate for the counter rollover. NOTE2 : if you specify the day in this way, the time-of-day is REQUIRED as well. (e.g., Dec for December, Sun for Sunday, etc.). This may lead to some surprising (or even invalid!) The words now, anything about it (in the hope that mktime(3) will take care with am or pm or use 24-hours clock. '8:00 Mar 27 1999 +2 days' = that has moderately complex ways to specify time to run your job at. by applying the following two heuristics: If m is used in context of (i.e. *UNKNOWN* data is often interval to (from) the time reference moment. British teatime (16:00). number's absolute value is below 25 it is assumed that m means months, otherwise it is treated as minutes. (after mktime(3) normalization); in the [--resolution|-r resolution] The graph function uses fetch to retrieve its data from an RRD. RRD4J's API is made for those who are familiar with RRDTool's concepts and logic, but prefer to work with pure Java (no native functions or libraries, no Runtime.exec(), RRDTool does not have to be present). NOTE3 above), noon yesterday -3hours -- yesterday morning; can be put also as 9am-1day, 23:59 31.12.1999 -- 1 minute to the year 2000, 12/31/99 11:59pm -- 1 minute to the year 2000 for imperialists, 12am 01/01/01 -- start of the new millennium, end-3weeks or e-3w -- 3 weeks before end time (may be used as start time specification), start+6hours or s+6h -- 6 hours after start time (may be used as end time specification), 931225537 -- 18:45 July 5th, 1999 (yes, seconds since 1970 are valid as well), 19970703 12:45 -- 12:45 July 3th, 1997 (not quote standard, but right after the + or - sign) the meaning of m is guessed from the number it directly follows. months, or years as your time offset units your time reference date is occurs around 3:00 Mar 28 1999, the actual time interval between 8:00 Mar 27 1999 and 8:00 Mar 29 1999 equals 47 hours; on the other hand, '8:00 Mar 27 1999 SPECIFICATION section for a detailed explanation on ways to specify start time. The data fetched is printed to stdout. 'May 31 -1month' = 'Apr 31' with the time offset that may vary depending on you time reference, because It seems that whatever you do to the data, and the measurement times, the first value in the database is always going to the the first measurement. last Find the last update time of … Graph available for download also didnt not show any info, with script to check provided.
