Setup SNMP Traps : Zabbix 5

[@BOCARGE2]

I am new to Zabbix. I have been put in charge of zabbix in my branch. This course is very helpful. I have gone ahead and purchased this course on Udemy. I hope to learn a lot so as to add value to my Branch.

I love watching your videos - excellent pacing / very straightforward / plain and simple explanations - great work !!

[@alexisvieiro7806]

Thank you! It was very useful for me!

[@bosromy2835]

@ SBCODE What causes SNMP Timeouts in zabbix. Cisco device Errors for SNMP "Timeout while connecting to"

Hi! Thanks for your video, it has benefited me a lot! How do you display the symbolic oid in your snmp trap message? Mine can only display digital oid, I want to change to display symbolic oid, but I haven't found the relevant settings yet. Thank you!!

Thank you very much for the detailed video.. One question, I have setup my ESXi to send traps in the zabbix server and I see them in the log file. In order to translate the OIDs what is needed?

[@sbcode]

normally templates that use SNMP will query the OID value. Much less problems with configuring that way. The names of the items will show you what the OID means. Look at the xml of this file, it is querying OIDs and not MIBs. share.zabbix.com/operating-systems/vmware/esxi-snmp-ver-3-4

@ SBCODE Can Zabbix alert you when cisco router config has been changed?

[@sbcode]

probably. does your cisco router send an snmp trap when its config is changed? It depends on your model of your router, and also if you enabled smnp traps on the router

[@GoogleReviewer8041]

@@sbcode Yes, cisco router send an snmp trap when its config is changed.

[@GoogleReviewer8041]

I just didnt know if you had to do anything extra on zabbix side to get that information.

[@sbcode]

if you configured everything properly, then all traps by default go into the snmptrap[fallback] item. But you can create specific snmptrap items to match specific strings. If you are not getting any snmptraps in Zabbix at all, then you need to recheck everything. Because this works, evidence is in the video, and I've done it many times now.

@@sbcode Can you Make a video for SNMPv3 Traps? Articles online are different from snmp v1 and v2 and confusing.

[@Silencer-311]

Спасибо за видео ! Могли бы Вы разобрать тему настройки SNMPv3 ?

[@djameleddinekhe4035]

hi, very good tutorial; but i want to know how to have traps when there is a change in the config on a cisco router interface for example

[@sbcode]

1. Read the documentation about your router to see if it can send traps when the config changes. 2. If it does, then configure your router to send traps when the config changes. 3. Watch this video again to see how to read the traps in Zabbix

[@oysed]

it's work!!! IT'S WORK!!! 👍

[@AndreyZnamenskiy]

Thank you for such a clear explanation. Can we put specific traps on a graph? The idea is to configure several domain controllers to send a trap for security events (Event ID 4625: Failed account logon), and put it on zabbix timeline graph, to visualize the insensitivity of failed logon events. Or maybe there is an easier way to do it?

[@sbcode]

Yes, there are many ways. One way is to create a dependent item (numeric unsigned) on your snmptrap.fallback item with a regex preprocessing step that looks for 'Event ID 4625: Failed account logon' and returns a 1, otherwise a 0.

@@sbcode Hi Do I still need to setup this SNMPtrapD if I am not using a proxy?

[@sbcode]

Yes

[@sharifi101]

Hi, Does Zabbix could automatically discovery all Network assets such as printer, PC's, router switches, servers etc...Like namp or lansweeper? I want to apply zabbix in LAN environment?

[@sbcode]

it depends on which protocols the devices use. If snmp then sbcode.net/zabbix/lld-actions-snmp/

[@davidbittencourt8781]

Hello, Friend! Thanks for this video. I have a problem: When i test it the trap appear in /tmp/zabbix_traps.tmp but it doesnt show on item from Zabbix frontend. why ?? The item is: Type: SNMP trap, key: snmptrap.fallback, type information log. Ps. I'm testing on my own Zabbix Server like host, i dont have proxies

[@sbcode]

give it a day, a watch the video again.

[@leonardoventura8050]

Hi Sean, nice work! Can we e-mail the trap too? Thanks!

[@sbcode]

the zabbix_trap_receiver.pl is a perl script. you can send emails, and many other things, using the perl language. Edit it any way you like, as long as you are confident writing perl.

[@LifeGeneralist]

Thanks a lot
