Cacti - check memory

To use this script template, perform the following steps:

1. Download cacti-netsnmp-memory.0.7.tar.gz to a temporary directory on the Cacti server machine.
2. Expand the archive with the command tar -xvzf cacti-netsnmp-memory.0.7.tar.gz, and change to the cacti-netsnmp-memory directory that is created.
3. Copy scripts/ss_netsnmp_memory.php to the <cacti>/scripts/ directory.
4. Access the Cacti installation in a web browser, click on the "Import Templates" menu item on the left side of the Console screen, and import the template/Net-SNMP_memory_graph_template.xml file. Cacti should automatically create the required graph template, data input method, and data template objects.
5. Click on the Devices menu item on the left side of the Console screen, select a *NIX host that is running Net-SNMP, and scroll down to the "Associated Graph Templates " table. Select "Host Memory - ucd/net - Memory Usage" in the "Add Graph Template " drop-down box, and click the "Add" button.
6. After the Device screen reloads, verify that the "Host Memory - ucd/net - Memory Usage" graph template is now present, and then click the "Create Graphs for this Host" link at the top of the page.
7. Locate the "Host Memory - ucd/net - Memory Usage" graph template, enable the checkbox to its right, and then scroll to the bottom of the page and click the "Create" button.

Note: these files are intended to be used with Cacti 0.8.6 and 0.8.7 and PHP 5.2, and may not operate as expected with other versions.
