Gathered information -is parsed so that client programs can comfortably request it via unified -interface. - -Netmond can be used as primary data source and as a notification subsystem -in a network monitoring framework. - -Netmond have a modular architecture. Modules work indepependently but use -common task scheduler, session multiplexor, topology correlator, variables -pool and output channels. The unique asynchronous polling algorithm -does not limit a number of simultaneously controlled objects. - -Collected data can be saved by variuos methods periodically or conditionally. -Also, a client program can request the data dynamically via network. - -Netmond considers the network as a collection of objects. All objects to be -monitored have to be described preliminary in a configuration file. Objects -polling works in parallel, not sequentially, like in other systems. Polling -requests are distributed over the poll interval as optimally as possible. -While executing, Netmond can dynamically determine topological dependences -of objects and interfaces and correct polling modes or even block polling for -subordinate objects. - -The Netmond deal the with following object types: - -* OBJECT - primary monitoring target, an object with IP address; -* INTERFACE - network interface, subobject of OBJECT; -* BGPAS - autonomous system number, subobject of OBJECT; -* BGPPEER - BGP peer for autonomous system, subobject of BGPAS; -* ENVTEMP - environment temperature (Cisco only), subobject of OBJECT; -* SERVICE - arbitrary network service, subobject of OBJECT; - -For any OBJECT type instance operator can define: - -* METHOD - list of polling methods; -* TRAP - list of traps methods; -* POLLING - polling interval (the time between METHOD calls); -* VARIABLE - list of variables, optional; -* SAVE - list of data saving methods, optional; -* SAVING - data saving interval (the time between SAVE methods calls); -* INTERFACE - list of network interfaces, optional; -* BGPAS - list of autonomous systems, optional; -* ENVTEMP - list of thermal sensors, optional; -* SERVICE - list of arbitrary services, optional; - -If BGPPEER list is not defined for a BGPAS instance, Netmond builds -this list automatically. - -The state of OBJECT is a result of execution of all associated methods from -METHOD and/or TRAP lists. Methods are evaluated sequentially until the first -error. The order of execution is defined by operator. - -VARIABLE values and state of subobjects INTERFACE, BGPPEER, ENVTEMP and SERVICE -are also evaluated during execution of METHODs and TRAPs. All subobjects have -their own SAVE list. - -Inside a METHOD definition the following protocols can be used: - -* PING - ICMP echo õ IP with Route Record option for topology discovery; -* SNMP - simple SNMP v1 request for specified VARIABLE OID; -* ROUTER - multiple SNMP v1 requests, indexing of certain tables, - extracting internal VARIABLEs values; -* TCP - simple TCP session with text chat capabilities, extracting - VARIABLEs values from answers; -* UDP - simple UDP sequence with arbitrary chat, extracting - VARIABLEs values from answers; -* DNS - DNS service check; -* RADIUS - RADIUS service check; -* TACACS - TACACS+ service check; - -TRAP collector expects SNMP v1 traps, with BGP Enterprise (RFC1657), -Cisco Private Enterprise or an arbitrary Enterprise defined by operator. - -The protocols are implemented as separate independent modules. New modules -could be added in the future. - -A VARIABLE instance is reffered to by an unique alphanumeric name. The name -can be used in the configuration file and for dynamic data request -via NetState service. Typically, the list and the names of VARIABLEs are -defined by operator. Several predefined VARIABLEs exist for some METHODs. - -A VARIABLE can be of any of the following types: - -* integer -* float -* IP address -* string -* SNMP OID - -The actual variable type is automatically determined on value assignment. -During Netmond execution the number of associated values for every -VARIABLE is maintained - the current value, previous value as well as -minimal, maximal, average and delta during the SAVING time interval, -if applicable. - -Netmod provides three SAVE methods to output VARIABLE values: - -* writing to a file; -* pushing to a pipe; -* passing as an argument for external program. - -SAVE methods are evaluated - - -* periodically, with SAVING interval -* on change of VARIABLE value; -* by condition - when a logical or expression with VARIABLE value become TRUE - -NetState service is an independent module of Netmond providing asynchronous -network access to current VARIABLE values for client programs. The whole -variables pool is presented as a hierarchy of variables and their owners in -format: "object!subobject!variable = value". The request could contain an -optional regular expression to filter the required output. This feature was -introduced for flexible dynamic data transmission to operator's GUI. - -Please, address all questions, proposals and complains regarding Netmond to -netmon@service.risp.ru mail list.
