Hi there I am running Net-SNMP (V 5.6.1.1-1, installed by net-snmp-5.6.1.1-1.x86.exe) on a Windos 2003 Server. I am building a base-image that will be used on several server. Some of these servers have additional hardware installed, some of them have databases an so on - and these servers as well as some of these optional parts/software-packages will be monitored by SNMP.
So the goal is to build a setup which allows to query values from 3 different sources: a) ... from script-written textfiles on the Server-Harddisks (using the extend in snmpd.conf) b) query some values from the original MS SNMP-Agent (for example: uptime) c) values which are generated/coming from vendor-specific extensions, for example: the speed of the a fan in a HP/compaq DL380 G4 server. Now I am unsure how to config snmpd.exe to achive this. a) and b) seems to work fine - but I am struggeling with c): I suppose the following: Most of the additional hardware and/or software that will installed on these servers is SNMP-ready, that means: Using the MS SNMP-Agent, I could also query specific values from these additional hw/sw. (for example: fan speeds of mainboard, and so on). In my understanding, the additional hw/sw links in a way to the MS SNMP-Agent. Now - as I want to query some values written in scriptfiles also - see a) above - I have decided to use net-snmp as intermediate between the SNMP-monitoring-software and the MS SNMP-Agent on the servers. If the monitoring software request a OID which I defined in a extend-command in snmpd.conf, it should return this value. In any other case, it should handle the request to the MS SNMP-Agent. (Then the MS SNMP-Agent can answer the request himself or by querying some of the "handlers" installed by the additional hw/sw). The question/problem now is: How do I configure net-snmp for this? Have read quite a lot in the helpiles and googeling, I think the solution is in the start-parameter -D of snmpd.exe I have found some examples and they all work in one way or the other, but I am not sure which one to choose ... In the helpfile, on Readme.win32, I found: snmpd.exe -Ivacm_conf,proxy,pass,pass_persist -> this proxies everything to the MS SNMP-Agent, I can't get back the values for the extend-statments in the snmpd.conf file I found also this one: snmpd.exe -I-udp,udpTable,tcp,tcpTable,icmp,ip,interfaces,system_mib,sysO RTable ...with the following hint: The above command will exclude all the Net-SNMP extensions that overlap with the default Windows (2003) extensions included with Windows. Other Net-SNMP modules take precedence over the modules loaded by winExtDLL. -> based on this hint, net-snmp would intercept queries for additional hw/sw - SNMP-providers on the server .... I think that I should positively enumarate the extensions which snmpd.exe should load. But I don't know which ones I have to load that snmpd.exe is forced to pass throuh everything to the MS SNMP-Agent, except for the OIDs I defined in the snmpd.conf-file by extend ... Any help on this would be appriciated. Maybe I have missunterstood something. Thanks a lot in advance! ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
