Limiting Master Group Collection

opHA supports Multi-Master, that means you can have several masters collecting information from the same slaves if required.  This could be especially useful if you wanted to have one master with all groups on a slave, and another master with different groups from different slaves, effectively sharing some information between groups.

To do this you use the group property in the Servers.nmis file.  Edit the file and add the group property in and a regular expression in for the groups, this will take the form

'group' => 'Brisbane|Boston|Saratoga',

This will match all groups contain the sub-strings, Brisbane, Boston or Saratoga.  A complete server entry would look like this.

 'demo' => {
 'community' => 'secret',
 'name' => 'demo',
 'config' => 'Config',
 'protocol' => 'http',
 'port' => '80',
 'host' => '192.168.1.42',
 'group' => 'Brisbane|Boston|Saratoga',
 'portal_protocol' => 'http',
 'portal_port' => '80',
 'portal_host' => 'demo.dev.opmantek.com',
 'cgi_url_base' => '/cgi-nmis8',
 'url_base' => '/nmis8',
 'user' => 'nmismst',
 'passwd' => 'C00kb00k'
 },

Test Master Collection

You can verify if the master is collecting data from the slaves by running this command
