Cacti list templates

This is where you can specify values for the Graph Item Inputs that you defined in the Graph Template. It really accelerates the deployment of a Cacti system across and enterprise of Devices. Once on that page, click Add on the right.

You will be redirected back to the edit page with the Associated Graph Templates and Associated Data Queries forms empty. Assume, you're searching for a specific set of templates to monitor a special type of device. Apart from designing templates from scratch, there's a good chance to find a solution in the Scripts and Templates Forum.

The set of templates is usually provided as a single XML file holding all required definitions for a data template and a graph template. However, also note that in the current version of Cacti, Packages are now importable as well.

When you import a Package all of the required additional file changes will also be accommodated. We will discuss Packages later in the documentation. If the XML file was downloaded, simply select that file from the Downloads location on your local system.

Cacti no longer supports pasting the XML into the browser window. Please pay attention the the Data Source Profile field.

By default, cacti will attempt to use your default Data Source Profile. However, you can change that at import time to use an alternate Data Source Profile or even the one from the Template itself, if it includes one. Also, not that if you have made local modification to an earlier version of a Graph Template , and wish to fully migrate to the new Graph Template for all your existing Graphs , please select Remove Orphaned Graph Items. Otherwise, your Graphs will look awkward in the end.

This should not be a problem for new Imports. It's also important to Preview the Template imports to access the impact that the import will have on existing database object. In earlier versions of Cacti, you were unable to determine what would actually change.

However, in the current and future versions of Cacti, you will be able to see all local modifications when performing a Preview prior to Importing. When Previewing, no changes are actually made ot your Cacti system. As mentioned previously, for a single OID based template, Importing the Template is all that will be required. However, for a script based template, the author will provide the script that has to be downloaded to the Cacti.

When importing templates, Cacti will perform a version check. Cacti will import only, if your current Cacti version equals or is higher than the exported one. Now that you know how to import, you may want to know in which way to export as well. Selecting the Export Templates gives. You may select to export a graph template, a data template, a Device Template or a Data Query. When selecting Include Dependencies , e. Output may be written to the browser or to a file for uploading.

What is Spine? Support Cacti Report an Issue. Release 1. Templates The real strength of Cacti is unleashed by using templates. There are five different types of templates with the basic Cacti installation: Device Templates - Define a Collection of Graph Templates and Data Queries that belong to a class of Devices Graph Templates - Define how to paint the Graph, it size, legend, left and right Axis and it Canvas Data Templates - Define how data is to be stored in the RRDfile and how often to collect that data Aggregate Templates - A special class of Graph Template that allows you to combine elements from multiple Graph of a common Template into one Graph Color Templates - A collection of color rotations to use for Aggregate Graphs While it is perfectly fine to define all Data Sources and Graphs without using Templates at all, the burden of this approach is high.

Table There are several replacement values available to you when using a Template. The resulting Data Source can still be used on Graphs , but no data will be fed to it until it is made active again. Minimum Value Here is where you specify the minimum value that is expected for this data source in the RRDfile.

If a value lower than the minimum is given, it will be stored as Unknown U. Maximum Value Here is where you specify the maximum value that is expected for this data source in the RRDfile. If a value higher than the maximum is given, it will be stored as Unknown U.

The update function takes the overflow into account. The counter is stored as a per-second rate. When the counter overflows, RRDtool checks if the overflow happened at the bit or bit border and acts accordingly by adding an appropriate value to the result. GAUGE: numbers that are not continuously incrementing, e. Floating point numbers are accepted. This field is usually '' or 2 data gathering intervals". Height The height of the Graph Canvas in pixels.

This is not the height of the overall Graph, just the Graph Canvas. Width The width of the Graph Canvas in pixels Base Value Should be set to for memory values and for traffic measurements. Slope Mode RRDtool graphs are composed of stair case curves by default.

This is in line with the way RRDtool calculates its data. Some people favor a more "organic" look for their graphs. Auto Scale Enable auto scale for the graph. This option must be check to use the next two options. Auto Scale Options Choose whether you would like to use --alt-autoscale ignoring given limits , --alt-autoscale-max accepting a lower limit , --alt-autoscale-min accepting an upper limit.

Logarithmic Scaling Choose if you want logarithmic y-axis scaling. But for logarithmic graphs, exponential notation is default. Choose if you want logarithmic y-axis scaling and scientific units. Rigid Boundaries Mode From the RRDtool manual "Normally rrdgraph will automatically expand the lower and upper limit if the graph contains a value outside the valid range.

With this option you can disable this behavior". Auto Padding If you have ever created RRDtool based graphs manually, you may have realized how annoying it can be to get text to line up properly. With this option Cacti will do its best to make the columns on your graph legend line up.

This option works best when your graph legend has a consistent number of columns. The number values do not correspond with the actual data.

This is caused by the fact that Cacti is designed to work with average values, meaning that the displayed values are averages of the actual data reported by Axigen. This averages are made by comparing the previous value of the graph with the new provided from Axigen.

With the exception of the current and maximum values displaying the value read when data was polled and the maximum value ever recorded, all the values displayed, including the graph, are average values. Besides the number values, there is another artifact caused by the generic orientation of Cacti to network devices; its data is, in many cases, represented by a decimal number and a multiple b, B, k, m, g, t which is used to represent the multiple or sub-multiple of a bit value e.

As you will often need a decimal value that does not represent bits and you will not want to be bothered by the attached letter of the multiple computed by Cacti, here are the steps to configure the newly-created custom template so as to display the decimal value only:. A free mail server version is also available, along with the business mail server and the MSP mail server , for Managed Service Providers, which also include features like personal organizer, AntiVirus, AntiSpam, or advanced security policies.

You are using an older browser, which will result in a bad experience. Upgrade your browser. Menu Close Mail Server. The canvas is painted from the first Graph Item till the last with each successive Graph Item rendered on top of the previous. Please keep this in mind when creating a Graph Template. Lastly, the Slope Mode gives the resulting Graphs a smoother look. These options are fairly self explanatory.

However, you can always view the RRDtool Documentation online for more information. The Grid Options are rarely necessary unless you have specific requirements to render the resulting Graphs with some exotic unit. The Legend options allow you to specify how the Legend should be placed on the resulting Graph modern RRDtool has several options that were not available in Cacti prior to Cacti 1.
