Configuring SNMP Settings
Configure Simple Network Management Protocol (SNMP) settings for the everRun system to allow SNMP management applications to remotely monitor your systems. (SNMP information pertains only to systems and not individual PMs.) You can enable SNMP requests and SNMP traps:
- SNMP request—A request sent to the system to retrieve the values of objects listed in the Management Information Bases (MIBs) supported by the everRun software. These MIBs include a system-specific MIB that is a collection of objects describing the everRun system. You can download a copy of the MIB file from the Drivers and Tools section of the Downloads page at https://www.stratus.com/services-support/downloads/?tab=everrun.
- SNMP trap—A message initiated by one of the nodes in the everRun system after an event such as an alert that is then sent to an identified list of recipients, typically a network management station (NMS).
Follow the appropriate procedure to enable SNMP requests or traps.
To enable SNMP requests
You can allow no users (Restricted) or any user using the default public community (Unrestricted) to send requests. Or you can customize the list of users that can send requests by editing the snmpd.conf file.
To customize the list
- Log in to the host.
- Manually edit the standard /etc/snmp/snmpd.conf file on both nodes.
- Save the file.
- Restart the snmpd process on each node by entering the command systemctl restart snmpd.
To enable SNMP requests
- Click Preferences in the left-hand navigation panel, to open the Preference page.
- Under Notification, click SNMP Configuration.
-
Activate the check box next to Enable SNMP Requests.
The selections in Step 4 appear as well as a read-only display of the snmpd.conf file.
-
Select one of the following:
Restricted (the default)—Allows no users to send requests.
Unrestricted—Allows public access.
Customized (available when snmpd.conf has been edited)—Allows customized access.
- Click Save. (Or click Reset to restore the previously-saved values.)
To enable SNMP traps
- Click Preferences in the left-hand navigation panel, to open the Preference page.
- Under Notification, click SNMP Configuration.
- Activate the check box next to Enable SNMP Traps.
- Type the name of the SNMP Community, or keep the default (public).
- Next to List of Recipients for SNMP traps (Version 2c), type the IP address or host name for each SNMP version 2 recipient, one per line.
- Next to List of Recipients for SNMP traps (Version 1), type the IP address or host name for each SNMP version 1 recipient, one per line.
- Click Save. (Or click Reset to restore the previously saved values.)
-
Configure your organization's firewall to allow SNMP operations, which enables SNMP management systems to receive alerts from and send traps to the everRun system. To do so, configure your organization's firewall to open the SNMP port:
Message Type: SNMP
Protocol: SNMP
Port: 161 (Get/Walk) 162 (Traps) -
Generate a test alert by clicking Generate Test Alert.
The everRun software generates a test alert and SNMP sends traps to recipients of SNMP traps; e-Alerts send a sample email with the subject "Test Alert" to all email recipients of e-Alerts, if configured (see Configuring e-Alerts); and Support Configuration sends a notification to your authorized Stratus service representative, if configured (see Configuring Remote Support Settings). Watch the Alerts History log (see the Alerts History Page) for delivery status.
