Configure Your NetXMS Server
You have to set some important server parameters after installation. These parameters are accessible through the Server Configuration window in the console. To access the Server Configuration window, press F9 or on the View menu click Control Panel to access the Control Panel window and then click the Server Configuration icon. To edit a setting, double click on the row in the table or right-click and select Edit. The following parameters may need to be changed:
| Parameter | Description |
|---|---|
| NumberOfStatusPollers | If you plan to monitor large number of hosts, increase this parameter from the default value to approximately 1/10 of host count. |
| NumberOfConfigurationPollers | If you plan to monitor large number of hosts, increase this parameter from the default value to approximately 1/20 of host count. |
| NumberOfDataCollectors | If you plan to monitor large number of hosts, increase this parameter from the default value to approximately 1/10 – 1/5 of host number. Use larger value if you plan to gather many DCIs from each host. |
| RunNetworkDiscovery | If you plan to use automatic network discovery, set this parameter to 1. You may also use Network Discovery item in Control Panel for simplified discovery network configuration. |
| DiscoveryFilter | If you want NetXMS to discover only specific hosts, set this parameter to the name of filtering script. After installation, NetXMS server has three preconfigured filtering scripts:
You can also create your own filtering scripts. See "Scripting" chapter for more information. |
| DefaultCommunityString | Set this parameter to default SNMP community string used on your devices. This community string will be used during network discovery process and manual host addition. |
| EnableSyslogDaemon | Set this parameter to 1 if you want to enable NetXMS built-in syslog server. |
After changing these parameters, you have to restart your NetXMS server so changes will take effect. For simplified network discovery configuration you may also use Network Discovery option in Control Panel.
Secure your installation
It's recommended to change a password for an admin user immediately after an installation to prevent possible unauthorized access to the system. You can change user passwords in the User Manager window. User Manager is available under Configuration from the main menu. To change a password, right-click a specific user record and select Change Password.
Discover the network
If you have enabled automatic network discovery, wait for initial network discovery completion. This process can take time, depending on size and complexity of your network. For large networks, we recommend that you let NetXMS run over night to gather the majority of network information available. You can watch discovery progress in a real time using NetXMS Management Console. Go to Object Browser or open default network map and see for new devices and networks.
Please note that for successful network discovery your network must meet the following requirements:
- NetXMS server must have access to switches and routers via SNMP.
- All your network devices must use the same community string, and this community string must be specified as value for DefaultCommunityString parameter in server's configuration.
Manually add nodes
If the automatic network discovery does not detect all of your hosts or devices, or you decide not to use network discovery at all, you may need to manually add monitored nodes to the system. The easiest way to accomplish this is to right-click on Infrastructure Services in the Objects pane and select Create node. You will be presented with the following dialog window:
Please note that adding a new node object may take some time, especially if a node is down or behind a firewall. After successful creation, a new node object will be placed into appropriate subnets automatically. As soon as you add a new node to the system, NetXMS server will start regular polling to determine the node status.
