Steps

How to

  1. In the Central list, select Monitoring Server Groups.
  2. Click the New Monitoring Server Group icon.The Monitoring Server / Monitor wizard appears.
  3. Select Monitoring Server Group and click Next. The Name and Connection step is shown.
  4. Type a name for the Monitoring Server and optionally provide a description. Finally type the hostname or IP address of the server into the Host field and click Next.
  5. The Resources step is shown. Check "Databases" and click Next.The Hosts/Device Agents screen appears.Note: Note: The host(s) or device agent(s) configured here should be the server(s) running PostgreSQL.
  6. Select PostgreSQL, then enter the TCP/IP port number, the user name, and password. The usual port number for PostgreSQL is 5432. If a catalog name is in use, add it as well.
  7. Click the Test Connection button to test the connection. If the connection is successful, you will see a pop-up containing some information about the PostgreSQL server. If the connection fails, you will see an error message explaining what went wrong.
  8. Click Next.
  9. Review the information to be sure it is correct, then check the "Create a new Monitor for this Monitor Server" box and click Finish.
  10. Enter a name for the Monitor and an optional description, then click Next.
  11. Now, choose the statistics you want to monitor. For each statistic, you can choose a "sample rate" that determines how often that statistic will be collected.
    • The "Commits" statistic tracks the number of database commits per second.
    • The "Rollbacks" statistic tracks the number of database rollbacks per second.
    • The "Total Connections" statistic tracks the number of users connected to the PostgreSQL server. This will never be zero, because monitoring itself uses at least one connection.
    • The "Per Catalog Connections" statistic tracks the number of users connected to a specific PostgreSQL database. If you use this statistic, you must enter the name of the database in the "Arguments" column.
