Discovery

Edit online

Discovery is the process to query and update information about the devices that are in SevOne NMS. Device discovery creates new objects in SevOne NMS, updates existing objects, and ultimately deactivates and deletes unused objects.

  • Manual Discovery - The Manual Discovery process runs every two minutes to scan the devices in SevOne NMS that you mark for discovery.
  • Automatic Discovery - The Automatic Discovery process tests the various plugins/technologies you configure for each device and updates the device's current state.

You define the Automatic Discovery time for each peer in the cluster on the Cluster Manager > Peer Settings tab.

  1. Click the Run the Automatic Discovery daily at drop-down and select the time to run the Automatic Discovery process.
  2. Click the second drop-down and select the time zone.

Email Server

Edit online
Note: The email server must be able to accept large attachments because a .pdf report can be over 20MB.
Warning: The current implementation of PHP SMTP mailer sends the hostname for the EHLO message but, it defaults to localhost.localdomain. This can result in the Alert Mailer not working under some SMTP server configurations.

Specify a specific name to use when connecting to mail servers or set the system to autodetect the FQDN of the system sending the mail and use that as the host name.

Run the following query on the Cluster Master. 

mysql (config)> UPDATE net.settings SET value = '<enter your.custom.hostname>' WHERE setting = 'mail_client_hostname';
By default the setting will be localhost.localdomain to match existing behavior. If the setting is set to an empty value, the OS hostname will be used instead. 

mysql (config)> UPDATE net.settings SET value = '' WHERE setting = 'mail_client_hostname';

The rest of the page enables you to enter the email server information for SevOne NMS to use to notify users of alerts and to send reports to users. You can update these settings on the Cluster Manager > Cluster Settings tab > Email subtab.

  1. In the Email Server field, enter the hostname or IP address of the SMTP email server for SevOne NMS to use to send emails.
  2. In the Username field, enter the user name SevOne NMS needs to authenticate onto the email server.
  3. In the Password field, enter the password SevOne NMS needs to authenticate onto the email server.
  4. Click the Connection Security drop-down and select a connection security protocol.
  5. In the Port field, enter the port on the email server for SevOne NMS to use.
  6. In the Test Email Address field, enter the email address to which you want to send a test email.
  7. Click Send Test Email to send a test email to the address you enter in the previous step.
  8. Click Next.
