Even if no consolidation is required, you are going to "consolidate" one PDP into one CDP. The four Consolidation Function options are AVERAGE, MIN, MAX, or LAST. But it makes sense to take only those rrd's, that belong to the same datasource (e.g. AVERAGE – The RRA is specified to use a consolidation function (CF) to calculate consolidated data points (CDP). Those primary data points will go through a consolidation function and this value will go to RRAs we have 3 times that matter: - step from database: Specifies the base interval in seconds with which data will be fed into the RRD. In the example above, the AVERAGE function is used is calculated an average. CF Consolidation Function. Ask Question Asked 3 years, 7 months ago. In this case “0.5” means, … XFF Defines XFiles Factor, the number of data points that can be anally probed by martians before RRD gives a crap. Can be AVERAGE, MIN, MAX, or LAST. AVERAGE = Takes the average of a certain amount of data points obtained and use the average as a point on the graph. The rrdtool graph command is designed to plot data at a specified temporal resolution, regardless of the actually resolution of the data in the RRD file. Assume the ifInOctets SNMP counter is saved in mrtg.rrd as the DS "in". ret_step is the step size in seconds, ret_ds_num the number of data sources in the RRD, ret_ds_names the names of the data sources, and a pointer to … Moderators: Developers , Moderators Using RRDtool without consolidation function. Since updatev requires direct disk access, the --daemon option … Each time a series of 40 PDPs is known, RRDtool consolidates them and stores them as a Consolidated Data Point (CDP). Cron Daemon throwing "rrdtool.error: unknown consolidation function" Thread starter TheBrawnyMan; Start date Jun 30, 2012; Status Not open for further replies. You can define any number of different consolidation … The created CDPs are stored in a Round Robin Archive (RRA). 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. T. TheBrawnyMan Neophyte. You first define "var_name_1" to be data collected from data source "ds_name" found in RRD "some.rrd" with consolidation function "CF". 0.5 – The field following (“xff“) defines how many data points need to be available for the CF to create one CDP. Is this even possible? Unrecognized consolidation function = No RRD's Post general support questions here that do not specifically fall into the Linux or Windows categories. with the same rrd file structure). Active 3 years, 7 months ago. It are these CPDs that are stored in the database. Consolidation Function: This is what tells GPRINT what to output or what consolidation of the data source to use. rrdtool - [workdir]| function Description ... (RRD), you can define at which interval this consolidation should occur, and what consolidation function (CF) (average, minimum, maximum, last) should be used to build the consolidated values (see rrdcreate). Note that depending on the arguments of the current and previous call to update, the list may have no entries or a large number of entries. Then the following DEF defines a variable for the average of that data source: DEF:inbytes=mrtg.rrd:in:AVERAGE Steps Defines how many Primary Data Points (PDPs) are consolidated using the Con-solidation Function (CF) to create the stored value. Viewed 348 times 0. Perform a fetch operation on the specified RRD Database given be filename, where cf is the consolidation function, ret_start is the start time given by unix epoch, ret_end is the endtime. I want to use rrdtool as a ringbuffer which simply forgets the oldest value if a new value arrives and RRA is full. Joined Jun 6, 2012 four rra's for each of the consolidation functions Of course, you may also enter a partly qualified dataset name.
