Cacti support a number of command line scripts. Please find them in the ./cli directory. As of current, following scripts are supported:
add_device.php add_data_query.php add_graph_template.php add_graphs.php add_perms.php add_tree.php copy_user.php poller_graphs_reapply_names.php poller_output_empty.php poller_reindex_hosts.php rebuild_poller_cache.php
| Numbers may vary! |
In the following examples, several numbers are shown as output from various scripts. They will vary between different installations. So don't bother, if your numbers will vary |
The poller cache holds all commands that cacti will issue during the polling process in an internal format. It is possible, to review the currenty contents of the poller cache by visiting System Utilities, View Poller Cache. It is possible to apply filters to this view; it will show up like

There are several circumstances, that may result in the poller cache being out of sync. An example would be a change of the name of a script used in a Data Input Method. This change is not automatically propagated to the poller cache. It is required, to run php -q rebuild poller_cache.php manually.
Calling the script with the parameter --help yields

Rebuilding the poller cache interferes with the poller operation. Please make sure, that the poller is not running and will not start during a rebuild operation |
