Zenoss snmp trap receiver
You can receive these traps within Enterprise Manager and start monitoring those applications from Enterprise Manager. Many of these applications can be configured to trigger SNMP traps when an alert condition takes place. It is often critical for an administrator to receive alerts from applications that are not managed by Enterprise Manager. This method supports SNMP version 1 (SNMPv1), SNMP version 2 (SNMPv2c), and SNMP version 3 (SNMPv3).įor more information, see Section 25.5, "Monitoring External Devices Using SNMP" and the Oracle Enterprise Manager Cloud Control Extensibility Programmer's Reference.Ĭreating new metrics to query SNMP agents by using SNMP adapters to allow Management Agents to query native SNMP agents on host targets for Management Information Base (MIB) variable information to be used as metric data.įor more information, see Section 25.6, "About Metric Extensions" and Chapter 9, "Using Metric Extensions".Ģ5.5 Monitoring External Devices Using SNMP By developing a metadata plug-in to receive SNMP traps, you can enable Enterprise Manager to monitor a product capable of throwing SNMP traps. This method supports SNMP version 3 (SNMPv3).įor more information, see Section 25.4, "Sending SNMP Trap Notifications" and Chapter 4, "Using Notifications".Įxtending the monitoring scope of Enterprise Manager to new entities by receiving SMNP traps or fetching SNMP data from or to the managed entity. For example, you can use SNMP to notify a third-party application that a selected metric has exceeded its threshold. Sharing event information with third-party management systems by generating SNMP trap notifications from Enterprise Manager to an SNMP management station. There are number of ways that Enterprise Manager uses SNMP as illustrated in Figure 25-1: This is because SNMP support is designed to query status, but not to change system parameters, whereas other tools are designed to set or tune system parameters.Ģ5.3 How Enterprise Manager Supports SNMPĮnterprise Manager supports SNMP by integrating with third-party management systems, sharing event information through SNMP traps and extending the monitoring scope of Enterprise Manager by monitoring new devices and targets using SNMP. However, for purposes of investigating and solving some problems, other Oracle tools such as Oracle SQL *Plus Worksheet may be more appropriate. SNMP support is invaluable for tracking the status of an entire network of Oracle applications - first, to verify normal operations, and second, to spot and react to potential problems as soon as they are detected.
Strictly speaking, SNMP support is intended more for monitoring Oracle products than for managing them. Providers of management applications can easily build customized solutions for Oracle customers because SNMP is an open standard. You can dynamically customize this map.Īdministrators see the current status of Oracle products, as shown by several status variables that are defined for each product in a management information base (MIB), or they can select which elements to view by their status.Īdministrators can anticipate exceptional conditions by defining thresholds and alerts, to respond to special situations as soon as they occur or to enable automatic responses.Īdministrators can store and analyze historical data that has been obtained through SNMP. These Oracle products are located, identified, and monitored in real time across enterprise networks of any size.Īdministrators see standard Oracle icons that represent Oracle products in a network map. The monitoring of key Oracle products is quickly integrated into any management framework based upon SNMP. The primary benefits of SNMP support include the following: Also, Enterprise Manager can extend its monitoring scope to devices that can be monitored using SNMP.
SNMP enables a single application to first retrieve information, then push new information between a wide range of systems independent of the underlying hardware.ĭesigned primarily for database, network, and system administrators, SNMP support integrates Enterprise Manager into a number of existing, widely-used management systems. The Simple Network Management Protocol ( SNMP) is a protocol used for managing or monitoring devices, where many of these devices are network-type devices such as routers, switches, and so on. It includes the following sections:Ībout the Management Information Base (MIB) This chapter provides a brief overview of Enterprise Manager support for SNMP. 25 Introducing Enterprise Manager Support for SNMP
