Besides the configuration tweaks suggested above, you can consider any
one of the following alternatives if you are monitoring over 10,000
interfaces for better scalability and performance
Steps to move MySQL databse to a
dedicated server
- Install a supported MySQL version on the dedicated server.
- Edit the file /opmanager/conf/database_params.conf
- Configure the host name and the MySQL port number for the
url parameter as follows:
url jdbc:mysql:// <name of the server where mysql is installed> :
<mysql port> /OpManagerDB
Example: url jdbc:mysql://database1-server:3306/OpManagerDB
How can I find
the number of devices and interfaces monitored in OpManager?
- In OpManager Web Client click the "About" link on top right
of the page.
- Search for the ‘Total Monitored Devices’ & ‘Total
Monitored Interfaces’ among the product details listed.
