-FS::part_export::cacti
-
-=head1 SYNOPSIS
-
-Cacti integration for Freeside
-
-=head1 DESCRIPTION
-
-This module in particular handles FS::part_export object creation for Cacti integration;
-consult any existing L<FS::part_export> documentation for details on how that works.
-What follows is more general instructions for connecting your Cacti installation
-to your Freeside installation.
-
-=head2 Connecting Cacti To Freeside
+=head1 METHODS
-Copy the freeside_cacti.php script from the bin directory of your Freeside
-installation to the cli directory of your Cacti installation. Give this file
-the same permissions as the other files in that directory, and create
-(or choose an existing) user with sufficient permission to read these scripts.
+=over 4
-In the regular Cacti interface, create a Host Template to be used by
-devices exported by Freeside, and note the template's id number.
+=item cleanup
-In Freeside, go to Configuration->Services->Provisioning exports to
-add a new export. From the Add Export page, select cacti for Export then enter...
+Removes all expired graphs for this export from the database.
-* the User Name with permission to run scripts in the cli directory
-
-* enter the full Script Path to that directory (eg /usr/share/cacti/cli/)
-
-* enter the Base Cacti URL for your cacti server (eg https://example.com/cacti/)
-
-* the Host Template ID for adding new devices
+=cut
-* the Graph Tree ID for adding new devices
+sub cleanup {
+ my $self = shift;
+ my $oldAutoCommit = $FS::UID::AutoCommit;
+ local $FS::UID::AutoCommit = 0;
+ my $dbh = dbh;
+ my $sth = $dbh->prepare('DELETE FROM cacti_page WHERE exportnum = ? and imported <= ?')
+ or do {
+ $dbh->rollback if $oldAutoCommit;
+ return $dbh->errstr;
+ };
+ $sth->execute($self->exportnum,$self->exptime)
+ or do {
+ $dbh->rollback if $oldAutoCommit;
+ return $dbh->errstr;
+ };
+ $dbh->commit or return $dbh->errstr if $oldAutoCommit;
+ return '';
+}
-* the Description for new devices; you can use the tokens
- $ip_addr and $description to include the equivalent fields
- from the broadband service definition
+=item exptime [ TIME ]
-After adding the export, go to Configuration->Services->Service definitions.
-The export you just created will be available for selection when adding or
-editing broadband service definitions.
+Accepts optional current time, defaults to actual current time.
-When properly configured broadband services are provisioned, they should now
-be added to Cacti using the Host Template you specified, and the created device
-will also be added to the specified Graph Tree.
+Returns timestamp for the oldest possible non-expired graph import,
+based on the import_freq option.
-Once added, a link to the graphs for this host will be available when viewing
-the details of the provisioned service in Freeside (you will need to authenticate
-into Cacti to view them.)
+=cut
-Devices will be deleted from Cacti when the service is unprovisioned in Freeside,
-and they will be deleted and re-added if the ip address changes.
+sub exptime {
+ my $self = shift;
+ my $now = shift || time;
+ return $now - 60 * ($self->option('import_freq') || 5);
+}
-Currently, graphs themselves must still be added in cacti by hand or some
-other form of automation tailored to your specific graph inputs and data sources.
