Snmp

You can confirm that AgentX is loaded by stopping Amportal/fwconsole and running "asterisk -cvvvvvvvvvv"
you should see the line "NET-SNMP version 5.5 AgentX subagent connected"
This also confirms that the module re_snmp is loaded.
MIBS:
Lookup the Asterisk MIB defs at +MIB+Definitions
Install the ASTERISK-MIB definitions into /usr/share/snmp/mibs/ASTERISK-MIB.txt
Install the DIGIUM-MIB definitions into /usr/share/snmp/mibs/DIGIUM-MIB.txt
But when I executed yum install asterisk-snmp the version that yum permit ti install is "astesrisk16-snmp-16.17.0-1.sng7.x86_64. i tried to install the same version according asterisk16-core (yum install astesrisk16-snmp-16.11.1-1.sng7.x86_64) but the yum command answer is: "No package astesrisk16-snmp-16.11.1-1.sng7.x86_64 available.
When I say SNMP support I mostly refer to the fact that there was an official asterisk-snmp package available that you could install and get to work from the official repositories that was regularly updated in lockstep with the asterisk-core package release until recently (as in a year or two ago).
Hi Rob--i tried both forms of the command below, but neither worked. it didn't seem to recognize snmpwalk as a valid command...not sure if the OS is out of date or something or what...appreciate the help though.
SNMP, or simple network management protocol, is a well-established way of monitoring and managing diverse sets of networked systems. In this series, we will introduce you to the basics of the protocol, teach you how to install the agent and manager components on several hosts, and demonstrate how to use the net-snmp suite of utilities to gather information and modify the configuration of remote hosts.
We have a switch stack which failed to report the temperature to our Cacti. We tried to restart the snmp process by using the command "restart snmp gracefully all-members". But some fpcs failed to restart.
I got an idea from this link, does anyone know would killing the snmpd from the shell of the master work? If snmpd is killed from the master, would the effects cascade to its members? Or do we need to kill it for each member? That's the only thing that I found useful so far; I searched the error message in Google but found no relevant results.
The snmp process is only running on the "routing-engine" and "backup" members, the linecards doesn't run the process. The routing-engine one runs the system for all the switches, and the backup is running a backup system, for the failover in case the routing-engine crashes.
The snmp sensor platform displays information available through the Simple Network Management Protocol (SNMP). SNMP uses a tree-like hierarchy where each node is an object, and is mainly supported by network-oriented devices such as routers, modems and printers.
If it's running linux, You could possibly use something like fetchmail/procmail to retreive emails from a server, and then further process the email to send a snmp trap out from the Spectrum Server itself. After that you could catch the trap with spectrum and do some further processing that way.
All of the MIBs listed above are enabled by default when SNMP is enabled. Some of the MIBs may not be present on all systems or versions but are enabled when present.
Administrators may be accustomed to utilizing the show snmp mib command in privileged EXEC mode to display a list of enabled MIBs on a device. Not all of the MIBs will be displayed in the output of the show snmp mib command but may still be enabled. Customers are advised to implement the entire exclude list as detailed in the Workarounds section of the advisory.
Administrators are advised to allow only trusted users to have SNMP access on an affected system. Administrators are also advised to monitor affected systems by using the show snmp host command in the CLI.
I am trying to get snmp monitoring setup so that I can monitor the controllers, leafs and spines. Getting it working for spines and leafs seems to be straightforward but not so for the controllers. I need this to work using OOB management and I have created an oob contract with the udp/161 filter, as suggested in various documents I have read, but I then lose access to the APICs.
What I'm looking for is a definitive step-by-step guide to setting up snmp for both controllers and leaf/spines. Is there such a thing? If not, can anyone share how they have setup snmp for their APICs and leafs/spines?
Does it make any difference if snmp is configured to go through the oob management or is inband management better? I have set my oob contract with filters for udp/161 and udp/162 but still nothing. The leaf/spines are all fine but the controllers just will not talk to my management server.
I think I have it sorted now. It seems the oob EPG and external Management Network Instance does not like a custom contract. Once I replaced my own contract with the common/default I can now connect to the APICs form my snmp server.
So in an example scenario, you might install snmpd on a machine to report its disk usage, CPU, etc when you need these numbers, and in addition, perhaps configure it to generate a trap and send it to a central location when the disk utilization crosses a particular threshold. The central server connects periodically to collect statistics, and in addition, is prepared to receive a trap at any time.
Anyhow - after doing that in a change window (the new JHF did not help ) - I tried switching off IPS which made no difference. I then switched off application control and what do you know - snmp started working.
@HeikoAnkenbrand it did look like the rule was evaluated and found to be allowed (at least this is what the logs said). I did see a knowledge base that mentioned the steps you listed but some snmp traffic was working fine so I did not go that way .. As mentioned the addition of an application control rule for snmp seems to have fixed the issue.
I have a DL360 G7 running as a VMware host. I have configured snmp through the ESXi software and that is working fine--I can run an snmpwalk and I'm pulling the information. However, when I run an snmpwalk through the iLO port I get this:
Unfortunately the rest of my hosts are G9s so I don't have anything to compare the setting to. I did have some G7 machines as VMware hosts a few years ago and I was pulling information from them through Nagios which uses snmp.
Does anyone have any ideas, suggestions or recommendations on how I can get snmp configured so I can get the information I'm after? This is so my Observium server can see into it and alert me when problems arise.
You made me curious so I did few tests; I have several boxes running iLO3 v1.88 - results. iLO on the windows boxes just passes SNMP throuigh to Windows so when I snmp-walk the iLO IP I get the response from Windows OS.
SNMP just isn't passed via iLO to the underlying OS which is ESXi in this case. Of course if I hit ESXi's own IP (not the iLO IP) with snmp-walk it walks just fine but not via the iLO IP. That is exactly the distinction here - if Windows OS was running on the bare metal then walking the iLO IP would produce results as if Windows was being walked using it's OS IP address so somehow iLO would pass SNMP to the OS * ONLY * if said OS is happens to be Windows? I haven't tested how this would behave if Linux was the underlying OS but maybe someone out there has? Either way though it doesn't help me with the ESXi issue...
