managed devices on IP networks and for modifying that information to change device behavior. Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks and more.[1] SNMP is widely used in network management for network monitoring. SNMP exposes management data in the form of variables on the managed systems organized in a management information base which describe cacti snmp error the system status and configuration. These variables can then be remotely queried (and, in some circumstances, manipulated) by managing applications. Three significant versions of SNMP have been developed and deployed. SNMPv1 is the original version of the protocol. More recent versions, SNMPv2c and SNMPv3, feature improvements in performance, flexibility and security. SNMP is a component of the Internet Protocol Suite as defined by the Internet Engineering Task Force (IETF). It consists of a set of standards for network management, including an application layer protocol, a database schema, and a set of data objects.[2] Contents 1 Overview and basic concepts 2 Management information base 3 Protocol details 4 Development and usage 4.1 Version 1 4.2 Version 2 4.3 SNMPv1 & SNMPv2c interoperability 4.3.1 Proxy agents 4.3.2 Bilingual network-management system 4.4 Version 3 5 Implementation issues 6 Resource indexing 7 Security implications 7.1 Autodiscovery 8 RFC references 9 See also 10 References 11 Further reading 12 External links Overview and basic concepts[edit] Principle of SNMP Communication In typical uses of SNMP one or more administrative computers, called managers, have t

Are there troubleshooting steps? important prtg snmp troubleshooting Created on Jan 30, 2013 9:25:15 AM by Gerald Schoch [Paessler Support] Permalink 4 Replies Accepted Answer Votes:1 Your Vote: Up Down General Introduction to SNMP and PRTG Every so often customers using PRTG Network Monitor report issues when trying to monitor their snmp error no systems using Simple Network Management Protocol (SNMP). In most cases, these issues result from a malfunctioning SNMP configuration or installation. The following article provides an overview about most common reasons for problems when monitoring via SNMP. Getting Started Important! Before going any deeper into troubleshooting, a good knowledge of the principles and functions of SNMP is necessary. Please refer to the following Microsoft articles for a general introduction to SNMP: What is SNMP? Simple Network Management Protocol How SNMP Works See also the following Paessler White Papers: Introducing SNMP and Putting SNMP into Practice You can find an overview about SNMP, MIBs, and OIDs in the following Knowledge Base article: SNMP, MIBs and OIDs—an Overview Basic Requirements Please ensure the following: Enable SNMP on the device. Allow access to SNMP for the machine running PRTG Network Monitor in the device’s security settings. Allow User Data Protocol (UDP) packages to travel from the machine running PRTG to the device you want to monitor and back. If the device and PRTG are on
1 and 2c of the Simple Network Management Protocol (SNMP). This module is installed using node package manager (npm): npm install net-snmp It is loaded using the require() function: var snmp = require ("net-snmp"); Sessions to remote hosts can then be created and used to perform SNMP requests and send SNMP traps or informs: var session = snmp.createSession ("127.0.0.1", "public"); var oids = ["1.3.6.1.2.1.1.5.0", "1.3.6.1.2.1.1.6.0"]; session.get (oids, function (error, varbinds) { if (error) { console.error (error); } else { for (var i = 0; i < varbinds.length; i++) if (snmp.isVarbindError (varbinds[i])) console.error (snmp.varbindError (varbinds[i])) else console.log (varbinds[i].oid + " = " + varbinds[i].value); } }); session.trap (snmp.TrapType.LinkDown, function (error) { if (error) console.error (error); }); Standards Compliance This module aims to be fully compliant with the following RFCs: 1155 - Structure and Identification of Management Information 1098 - A Simple Network Management Protocol (version 1) 2578 - Structure of Management Information Version 2 (SMIv2) 3416 - Simple Network Management Protocol (SNMP) (version 2c) However, this module does not implement, or export any method that might help to implement, the SNMP version 2c report request type. Constants The following sections describe constants exported and used by this module. snmp.Version1 & snmp.Version2c These constants are used to specify which of the two versions supported by this module should be used. snmp.ErrorStatus This object contains constants for all valid values the error-status field in response PDUs can hold. If when parsing a PDU the error-index field contains a value not defined in this object the constant snmp.ErrorStatus.GeneralError will be used instead of the value in the error-status field. The following constants are defined in this object: NoError TooBig NoSuchName BadValue ReadOnly GeneralError NoAccess WrongType WrongLength WrongEncoding WrongValue NoCreation InconsistentValue ResourceUnavailable CommitFailed UndoFailed AuthorizationError NotWritable InconsistentName snmp.ObjectType This object contains constants used to specify syntax for varbind objects, e.g.: var varbind = { oid: "1.3.6.1.2.1.1.4.0", type: snmp.ObjectType.OctetString, value: "user.name@domain.name" }; The following constants are defined in this object: Boolean Integer OctetString Null OID IpAddress Counter Gauge TimeTicks Opaque Integer32 Counter32 Gauge32 Unsigned32 Counter64 NoSuchObject NoSuchInstance EndOfMibView snmp.TrapType This object contains constants used to specify a type of SNMP trap.
