Installing a SNMP tool Debug and troubleshooting SNMP is notoriously awkward. Use this guide and you'll soon master the tools needed, get a better understanding of how SNMP works and most importantly ensure that a device correctly replies to your queries. Several applications exists for executing an SNMP query - some with a GUI others as a command-line tool. W e recommend the command-line tool and if you're using Microsoft Windows consider downloading this ready to use otherwise install a version matching your type of operating system (packages exists for Mac OS X and different flavours of Linux/Unix). After downloading and installing SnmpWalk open a 'command prompt' and navigate to the folder where SnmpWalk is located. Create a SNMP query The following is a simple SNMP query using SnmpWalk: snmpwalk -Os -c community string -v SNMP version IP OID. community string: By default most SNMP enabled devices uses 'public'.
You may have changed it through the administration tool used to configure the device. SNMP version: SNMP protocol version, '1' or '2c'. Most devices supports '2c'. IP: IP address of the device. OID: SNMP OID value(s) that you wish to read (optional, but if omitted expect a very long response). Hello,.
It depends on what type MIB the SNMP device supports, but you might be able to collect interfaces information from OID.1.3.6.1.2.1.2.1. You can do it with this command, this will scan all ip addresses IP range 172.16.132.0 otherwise you need to create a powershell to do it for you. For i in $(seq 1 254); do echo 172.16.132.$i; sudo nmap -sU -p 161 -script=snmp-interfaces.nse 172.16.132.$i grep 'open'; done I can recommend you to try Panorama9 for 30days free, we will automatically start scanning your network for devices with SNMP enabled and monitor NAS, Switches, Printers and UPS. You can sigh up here for a free trail -. That might be that I copied a specific OID from the Host-Resources MIB, if you run it against.1.3.6.1.2.1.25 you should get the full MIB returned, it should't matter what version you are using. But the MIB.1.3.6.1.2.1.25 will only contain data about the host and number of users, I can't find any MIBs containing user information, but you might be able to find the information some other MIBs I'll suggest you run a SNMPwalk against a machine where you know the username etc and ask for OID.1.3. And pass the result to a txt file, where you easily cam search for the specific username.
This output will contain a massive numbers of lines, so therefore pass it to a file. Hope that helps. Best regards Claus Tjoerndal. Hi, i am a new in windows server and SNMP and i'm facing a critical alarm on my Nagios system from the Windows server 2008 ( Domain Controller) DC01 C: Drive Space CRITICAL 01:20:34 5d 9h 36m 1s 2/2 CRITICAL - Socket timeout after 10 seconds D: Drive Space CRITICAL 01:20:34 5d 9h 36m 1s 2/2 CRITICAL - Socket timeout after 10 seconds Memory Usage CRITICAL 01:20:34 5d 9h 36m 1s 2/2 CRITICAL - Socket timeout after 10 seconds i tried to restart the SNMP service but that didn't change anything.
Please help ASAP. Hello, Thank you for your comment. The error message you're receiving sounds like your Nagios server isn't able to create a connection to your Windows server. The problem can be that your Windows server is simply not replying on the SNMP request. I will suggest that you start with a simple check from the Nagios server and e.g.
Your own machine just to make sure that your Windows server is replying on SNMP. This can be done by running a program called SNMPwalk, you can find the program in the article on top. Snmpwalk -Os -c pulic -v 2c 192.168.20.113 iso.3.6.1.2.1.1.1 If either of those test replies back with a result, the problem is located on your DC01, then try run the same cmd on the server, if you get a reply running the cmd locally, you might have a firewall problem. And just for the sake of it, Panorama9 have a 30-day free trial for our cloud based monitoring tool, and with our product you don't need to worry about how to setup specific rules to monitor e.g.
Q A: Is There An Snmp Oid To Query For Mac Free
Your disk drive, memory rules etc. Come on guys, if you are trying to test snmp you should know by now how to execute an EXE. Snmpwalk its a tool not included in windows, as the article says. You need to follow the download link, open the zip and extract it on the folder you are working on or extract it to c: windows system32 if you want to have it available in any prompt folder. The guys from SNMPWalk changed the command line switches format, so just execute snmpwalk with no switches and at the end you will see some examples. The theory its the same.
Q A: Is There An Snmp Oid To Query For Mac Mac
Since we are on the Solarwinds sub it is worth pointing out that solarwinds installs a basic gui driven one as well when you install orion. Defaults to C: Program Files (x86) SolarWinds Orion SnmpWalk.exe Feed that application or whatever other mibwalk tool you use an IP address and a community string, it asks that machine all the possible SNMP values it can get and dumps them to a text file. As far as being unfamiliar with the concepts of mibs and oids in general, you will come across a series of numbers like 1.3.6.1.2.1.1.5.0, this is an OID and it represents a specific kind of address you can query against a device to get back some kind of metric. Things are laid out in this giant hierarchical nested tree kind of structure.
Basically everything most people deal with will start with either 1.3.6.1.2 or 1.3.6.1.4, the.2's are generic and most SNMP capable devices will respond to some of them, and the ones in the.4 branch are associated with enterprise companies. The device vendors get assigned a value by the standards organization, for example Cisco is 1.3.6.1.4.1.9 ad Dell Computers is 1.3.6.1.4.1.674.
There are a TON of these, and sometimes it is a mess to find something because of things like companies acquiring each other and using different branches for parts of their product lines, etc. How things get organized inside of a branch is pretty much up to the vendor. They publish documentation of their OID's and how they should work and these are your MIB's, but for the most part everyone does it differently so that's why you end up just querying the device (running a mibwalk) to see what it responds to, otherwise you might spend all your time looking up MIB documents and trying to guess which OIDs apply to your specific model. The walk will just report the current stats from all of the OIDs your hardware supports.
In Solarwinds case you can take any of the OIDs that you see and enter them into the UNDP tool on the orion server or use the mib browse that is built into the web gui to see the descriptions. These are taken directly from the vendor documentation and some have great info, others leave you guessing. For the most part you just end up looking around trying to keep an eyeout for values that might be useful for you, like hardware states or serial numbers or whatever it is that you are hoping that you can find with SNMP.
