Setting up SNMP (Simple Network Management Protocol) for the SPM Monitoring system involves several key steps, starting from enabling and configuring SNMP on the devices you want to monitor, to configuring the SPM Monitoring system itself to collect and analyze SNMP data. Below is a general instruction that can be adapted depending on the version of the SNMP protocol of your specific device.
- SNMP triggers are configured separately for each of the hosts. Click the ‘Details’ button on the required host where SNMP functionality is enabled or an SNMP Agent is installed, if it’s a computer.
- Enable the ‘Use SNMP Notification’ checkbox and open the ‘SNMP trigger configuration’ window.
- Select the SNMP version that matches the version used on the device you want to monitor. Typically, the following options are available:
- V1: The oldest version, rarely used due to low security level.
- V2: More commonly used version, supports most features and is fast enough, but also has a low security level.
- V2U: Another variant of V2 with password authentication.
- V3: The most modern and secure version, supports authentication and data encryption.
- If using SNMPv1 or SNMPv2, enter the “Community String.” This is a public identifier used for community-level authentication. The default is often “public”.
- For SNMPv3 and V2U, additional security parameters may need to be specified, such as a username and password.
- Set the port number used for SNMP (default is 161).
- Set the timeout period, which determines how long the system will wait for a response from the device before considering the attempt unsuccessful.
Adding a new SNMP trigger
- Right-click on an empty field and select Add new Trigger.
Fill in the fields for the new trigger:
- Trigger Name: Enter a name for the trigger that reflects its function (e.g., “Network port #5 is to load”).
- OID: Enter the OID (Object Identifier) that corresponds to the parameter you want to monitor (e.g., 1.3.6.1.2.1.1.3 for system uptime).
- Value type: Choose the type of value expected to be received from the OID (e.g., Integer, String, etc.).
- Condition: Specify the condition for the trigger to fire (e.g., >= for “greater than or equal to”).
- Expected Value: Indicate the expected value at which the trigger should activate (e.g., a CPU load value considered high).
- Test: Click Test button to check that trigger works ok and look at Trigger status in the ‘Trigger’ field.
The first SNMP trigger for this host is configured. Now, when the trigger condition is met, you will receive a notification through the notification system.
You can also configure notification templates and customize the information transmitted to a notification messages.
Note: Use Mib Browsers to parse .mib files provided from your device manufacturer for getting OIDs for device metrics.
