This process starts with first creating a Threshold Template for the specific Graph Template in question, and then from Graph Management selecting the Graphs that you wish to apply this Template to. Though this method continues to work today, we believe that with the support of associating Threshold Templates with Device Templates, that this method will become less popular over time. When creating your first Threshold using thold, you need to be first understand the Threshold Type.
Lastly, the Baseline Deviation provides a floating window in the 'Time reference in the past' to measure change. If the change in the measured value either goes up or down by a certain value in that time period, an alert will be triggered. The simplest form is the Exact Value data manipulation where thold simply takes the raw value collected from Cacti's Data Collector, and applies rules to it.
The Percentage Data Manipulation requires you to select the 'primary' Data Source as the Numerator, and then when selecting 'Percentage', you will be able to select the Denominator of the percentage calculation. If you fail to perform these steps, thold will appear to not work as expected. Lastly, please note that several forks of the thold plugin are available from different sources.
These forks of thold are not necessarily compatible with the current version of Cacti's thold plugin. Please be aware of this when installing thold for the first time. The thold plugin has been in development for well over a decade with increasing functionality and stability over that time. There have been several contributors to thold over the years. We hope that version 1. We are always looking for new ideas.
So, this won't be the last release of thold, you can rest assured of that. Skip to content. Star Branches Tags. Could not load branches. Could not load tags. Latest commit. Fixing Issue - Uptime Calculation.
Page style gives you two choices of layout - a big stack of fullsize maps on one page, or a grid of thumbnails, each of which leads to a full size map view. From either view, you can also choose the Cycle mode. Cycle mode gives you an automatically refreshing page cycling through all the maps available to you.
If you only have one map or a user is only allowed to see one , then the user will get a full-size map regardless of the setting. Also in the settings page, you can choose the maximum size of the thumbnails. The Page style setting takes effect immediately, but the thumbnail size is used next time the maps are generated by the poller. You can choose how long each map stays on-screen for. The default is 'Automatic', which takes the 5 minutes that the data is valid for a poller cycle , and divides it evenly between the available maps - if you had 5 maps, they would each get 1 minute onscreen before the page reloaded with new updated maps.
This is nothing to do with changing how the Cacti poller works! Output Format allows you to change the image file format used by the plugin. PNG is the default. Map Rendering Interval is intended for advanced users only. If you use the 1-minute polling patch for Cacti, you might not want to have Weathermap redraw your maps every minute. This option allows you to change this, so that Weathermap only redraws every n polling cycles. During that one cycle when it does redraw, your polling cycle will still be longer than usual, so you can also turn off the poller part of Weathermap, so that it doesn't redraw at all.
This allows you to use the user-access parts of the plugin, but manage the redrawing of maps yourself. To redraw all the maps outside of the standard Cacti poller process, there is a special PHP script weathermap-cacti-rebuild. To use this, you need to edit it, and change the path in the top of the file to point to your Cacti root directory.
You will need to change the paths to php and cacti, and the user that cacti runs as. In normal use, you don't need to add a cron job - the Cacti poller does this work for you. With TheWitness' Boost plugin installed in Cacti, the rrd files are no longer updated every poller cycle. There is support in the Weathermap plugin to directly access data from the poller instead of rrd files.
You can find out more in the Targets Reference. This also collects data into the Cacti database, and has it's own benefits if you want to produce periodic summary maps. Both of the above datasource plugins allow you to access some additional information from the Cacti database about the data being polled see the Targets Reference for more. Additionally, there are some other datasource plugins that can access more information from Cacti: cactithold works with cigamit's THold plugin, and cactihost accesses Cacti's host status information.
Weathermap has quite a lot of logging. If you have a problem, then check your cacti. Most normal errors will appear in here with Cacti's logging level set to LOW. Also see the FAQ section of this manual, and the network-weathermap. It worked by running the normal map update process immediately, but did so as the user that runs the webserver. This causes some permissions problems that you need to understand in order to use it. People would just click it and complain it didn't work, or killed their maps.
I added a warning explaining the problem.
