Note:
- To learn more about changing port numbers, click here.
- To ensure OpManager Plus functions properly, configure the firewall to allow traffic through all the ports listed in the table, as these ports are required for communication between OpManager Plus, its agents, devices, and integrated services.
- Connection: Specifies the direction of communication for each port, such as "Outbound" (from OpManager Plus to external systems), "Inbound" (from external systems to OpManager Plus), or "Internal" (within the OpManager Plus server itself).
- OpManager Plus uses ICMP (no TCP/UDP ports) for device discovery; refer to the table for the default ports used for each protocol. It is recommended to associate credentials for accurate classification and data collection.
- OpManager Plus uses ICMP for initial device discovery. If ICMP is unsupported, use the 'Add Device' or 'CSV file' options instead.
- Agent: For proper functioning of agent-based monitoring in OpManager Plus, ensure that the OpManager Plus webserver port (HTTPS, 8061 by default) is allowed for outbound requests from each agent-monitored device.
- For Application Manager plugin, refer this document to learn more about its port requirements.
Database Requirements
The following table lists the basic requirements for your OpManager Plus database server.
PostgreSQL
Comes bundled with the product (PostgreSQL version 14.18).
For Remote PostgreSQL, OpManager Plus supports PostgreSQL versions 14.18 to 14.x.
In case of failover, please use MS SQL.
Microsoft SQL
1. Supported versions:
SQL 2022 (from build 12.8.452) | SQL 2019 | SQL 2017 | SQL 2016
2. Important Notices:
1. For production use 64 bit versions of SQL
2. Recovery mode should be set to SIMPLE.
3. SQL and OpManager Plus should be in the same LAN. Currently WAN based SQL installations are not supported.
4. Developer edition of SQL Server is not supported.
3. Collation:
- English with collation setting (SQL_Latin1_General_CP1_CI_AS)
- Norwegian with collation setting (Danish_Norwegian_CI_AS)
- Simplified Chinese with collation setting (Chinese_PRC_CI_AS)
- Japanese with collation setting (Japanese_CI_AS)
- German with collation setting (German_PhoneBook_CI_AS)
4. Authentication:
Mixed mode (MSSQL and Windows Authentication).
5. BCP:
The "bcp.exe" and "bcp.rll" must be available in the OpManager bin directory.
The BCP utility provided with Microsoft SQL Server is a command line utility that allows you to import and export large amounts of data in and out of SQL server databases quickly. The bcp.exe and bcp.rll will be available in the MSSQL installation directory. If MSSQL is in a remote machine, copy bcp.exe and bcp.rll files and paste them in the <\OpManager\bin> directory.
The SQL server version compliant with the SQL Native Client must be installed in the same Server.
6. User-role requirement:
Server roles - "dbcreator", "public" and "sysadmin".
User Mapping - Map this login to "master" with database role ownership as "db_owner" and "public". Click here to learn more.
The SQL server version compliant with the SQL Native Client must be installed in the same Server.
General Information
Antivirus scanners interfering with database files may affect normal functioning of the database. Please make sure that your anti-virus scanners do not affect the functioning of the product/database.
We recommend using the latest version for the best experience.
