OK u:0.01 s:0.00 r:0.55 The specification is called "at-style" after the Unix command at(1) that has moderately complex ways to specify time to run your job at a certain date and time. It consists of a sign (+ or -) and an amount. browser like Mozilla Firefox or Currently I have the same situation again: rrdtool fetch localhost_proc_7.rrd AVERAGE If you ever owned a classic HP calculator, you may still remember how RPN math works. see the -l option in the rrdcached manual. end-3weeks or e-3w -- 3 weeks before end time (may be used as start time specification). NOTE: The content of this website is accessible with any browser. My Cacti installation gives only nan values. 5 minute averages, will be chosen which in this case is not what you want. Some special times of day are understood as well, including midnight (00:00), noon (12:00) and British teatime (16:00). Or if some pictu The data fetched is printed to stdout. 1402758000: -nan *UNKNOWN* data is often represented by the string "NaN" depending on your OS 's printf function. Consider the following example: This RRD collects data every 10 seconds and stores its averages over 5 minutes, 15 minutes, 1 hour, and 1 day, as well as the maxima for 1 hour and 1 day. to your account. 1402758300: -nan To cope with this, when you use days, weeks, 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 hope that mktime(3) will take care of this later). rrdtool fetch rn23.rrd MAX --start 1491210243 --end now. Consider upgrading to a standard conformant I was hoping someone could help me understand how values are computed in RRD. to make sure you are feedin what you think you are feeding? 06/21/2014 05:35:02 PM - SYSTEM STATS: Time:0.7291 Method:cmd.php Processes:1 Threads:N/A Hosts:2 HostsPerProcess:2 DataSources:6 RRDsProcessed:5. ds[proc].last_ds = "97" Alternatively, you can use day-of-week-name (e.g. The words now, start, end can be abbreviated as n, s, e. The time offset specification is used to add/subtract certain time intervals to/from the time reference moment. 'May 31 -1month' = 'Apr 31' (meaningless) = 'May 1' (after mktime(3) normalization); in the EET timezone '3:30am Mar 29 1999 -1 day' yields '3:30am Mar 28 1999' (Sunday) which is an invalid time/date combination (because of 3am -> 4am DST forward clock adjustment, see the below example). though if a specific RRA is desired this will not ensure the start and end fall within its bounds. RRDtool can be easily integrated in shell scripts, perl, python, ruby, lua or tcl applications. If both are present, the command line argument takes precedence. 1402773000: 8.5000000000e+01 It is unclear to me why I see useful data with "info" but get only nan data with "fetch AVERAGE". noon yesterday -3hours -- yesterday morning; can also be specified as 9am-1day. Address of the rrdcached daemon. By default, It is in some ways accurate because leaving aside missed wrap-arounds and resets that many bits did pass through that interface for the time specified. Ved nogen jer, hvorfor det kun genkendte tidsstemplet, men ikke temperaturen? resultatet viser dette: 1491270300: -nan 1491270600: -nan 1491270900: -nan 1491271200: -nan 1491271500: -nan 1491271800: -nan 1491272100: -nan 1491272400: -nan 1491272700: -nan 1491273000: -nan 1491273300: -nan .

It works after restarting the snmpd. epoch+19711205s unambiguously denotes timestamp 19711205 and not 1971-12-05 00:00:00 UTC. You can also specify the day as a full date in several numerical formats, including MM/DD/[YY]YY, DD.MM. However, when I run rrd fetch I get a lot of NaN values (between a quarter and a third of values) so the generated graphs have gaps too. What else can be the reason for only getting nan values? NOTE3: If you specify time offset in days, weeks, months, or years, you will end with the time offset that may vary depending on your 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 long, and even 1 day may be not equal to 24 hours twice a year, when DST-related clock adjustments take place).

Adding updates but fetch shows NaNs. ds[proc].minimal_heartbeat = 600 RRDtool is a wonderful tool for collecting and graphing data.. RRDtool is the OpenSource industry standard, high performance data logging and graphing system for time series data. You might try rrdtool fetch subdata.rrd AVERAGE -r 15m -s -1h However, this will almost always result in a time series that is NOT in the 15 minute RRA. The time-of-day can be specified as HH:MM, HH.MM, or just HH. Please note that due to thread-safety reasons, the time specified with -s and -e cannot use the complex forms described in "AT-STYLE TIME SPECIFICATION". The data fetched is printed to stdout. The data is produced by Cacti. PHP rrd_fetch - 13 examples found. Negative numbers are relative to the current time. ds[proc].unknown_sec = 0, rrdtool fetch localhost_proc_37.rrd AVERAGE, 1402757400: -nan In this case you should either quote the whole phrase to prevent it from being taken apart by your shell or use '_' (underscore) or ',' (comma) which also count as whitespace (e.g., midnight_Thu or midnight,Thu). *UNKNOWN* data is often represented by the string "NaN" depending on your OS's printf function. the interval you want the values to have (seconds per value). ds[proc].min = 0.0000000000e+00 The fetch function is normally used internally by the graph function to get data from RRDs. ds[proc].minimal_heartbeat = 600 RRDtool is written by Tobias Oetiker with contributions from many people all around the world.

If you see this text, this means The following environment variables may be used to change the behavior of rrdtool fetch: If this environment variable is set it will have the same effect as specifying the --daemon option on the command line. OK u:0.01 s:0.00 r:0.36 The end-time is adjusted by the same amount. 12am 01/01/01 -- start of the new millennium. The info function prints the header information from an RRD in a parsing friendly format.. Consider now that you want to fetch the 15 minute average data for the last hour. But this does not seem to be the reason for the issue. fetch will analyze the RRD and try to retrieve the data in the resolution requested. start of the time series. /usr/bin/rrdtool update /usr/share/cacti/rra/localhost_proc_7.rrd --template proc 1403374802:102, rrdtool fetch localhost_proc_7.rrd AVERAGE See "RESOLUTION INTERVAL". 2- L'as tu bien entourée de backquotes ` … However, this will almost always result in a time series that is NOT in the 15 minute RRA. ds[proc].type = "GAUGE" rrdtool is showing the average rate for that time period. epoch is useful to disambiguate between a timestamp value and some forms of abbreviated date/time specifications, because it allows one to use time offset specifications using units, eg. Vet ni varför det bara kände igen tidsstämpeln men inte temperaturen? Assuming, you've got some valid rrdtool update in step 3, perform a rrdtool fetch AVERAGE. There are, however, cases when whitespace is required (e.g., 'midnight Thu'). privacy statement. The fetch function is normally used internally by the graph function to get data from RRDs.

Whitespace can be inserted freely or omitted altogether. ds[proc].value = 1.8800000000e+02 The .rrd files look good when I use "rrdtool info". The data fetched is printed to stdout. See also "AT-STYLE TIME SPECIFICATION" for a detailed explanation of how to specify the end time. When present, it should come first, when omitted, it defaults to now. 1.903, -0.424, etc.) This "breaks" applications looking for 'nan' (OpenNMS). RPN basics: Step 0 15+23 = 38 1: NAN 2: NAN 3: NAN The fetch function is normally used internally by the graph function to get data from RRD s. fetch will analyze the RRD and try to retrieve the data in the resolution requested. start+6hours or s+6h -- 6 hours after start time (may be used as end time specification). res are missing, then the mirror may not have picked up the contents of the inc directory. NOTE1: this is different from the original at(1) behavior, where a single-number date is interpreted as MMDD[YY]YY. What else can be the reason for only getting nan values? In fact, I tried to make a simpler test with 1 DS, something like: rrdtool create x.rrd \ DS:test1:DERIVE:100:U:U \ RRA:AVERAGE:0.5:48:24 \ RRA:AVERAGE:0.5:1488:31 rrdtool update x.rrd N:13 rrdtool update x.rrd N:30 rrdtool update x.rrd N:45 But I couldn't get any values: rrdtool fetch x.rrd AVERAGE test1 1196928000: NaN 1196942400: NaN 1196956800: NaN … Using the bash shell, this could look be: Apart from the traditional Seconds since epoch, RRDtool does also understand at-style time specification. the name of the RRD you want to fetch the data from. rrdtool info localhost_proc_37.rrd | grep ds, ds[proc].index = 0 The graphical ds[proc].unknown_sec = 0, After enabling DEBUG for poller I see e.g. I've got a cronjob set to run every 10 minutes that should run the update command, but when I dump the contents of the rrd file afterwards, all values show up as NaN. I use rrdtool 1.4.8. rrdtool info localhost_proc_37.rrd | grep ds NOTE2: if you specify the day in this way, the time-of-day is REQUIRED as well. Start (end) can be used to specify a time relative to the start (end) time for those tools that use these categories (rrdfetch, rrdgraph) and epoch indicates the *IX epoch (*IX timestamp 0 = 1970-01-01 00:00:00 UTC). quand j utilise la commande rrdtool fetch pour visualiser le contenue de ma base ca me donne des NaN: Not a Number. The fetch function is normally used internally by the graph function to get data from RRD s. fetch will analyze the RRD and try to retrieve the data in the resolution requested. 1402758600: -nan. However, when compiled on 64bit RHEL5, rrdtool fetch returns 'nan'. However often the graphs are interpreted incorrectly as … The data fetched is printed to stdout. This allows rrdtool to return fresh data even if the daemon is configured to cache values for a long time. The .rrd files look good when I use "rrdtool info". The data fetched is printed to stdout. I'm trying to update an rrd file with new data every 10 minutes. The fetch function is normally used internally by the graph function to get data from RRDs. ds[proc].value = 1.9400000000e+02 At this step, it is wise to check step and heartbeat of the rrd file as well. It uses RPN math for this. But this does not seem to be the reason for the issue. Finally, you can use the words now, start, end or epoch as your time reference. Check rrdcreate if you are uncertain about the meaning of the individual keys.. filename. See also "AT-STYLE TIME SPECIFICATION" for a detailed explanation on ways to specify the start time. 19970703 12:45 -- 12:45 July 3th, 1997 (my favorite, and it has even got an ISO number (8601)).
