Hi, I have a mikrotik CCR1072-1G-8S+ with firmware 6.48.6 LTS on which I have hundreds of virtual interfaces (c-vlan , s-vlan).
I have some problem with snmp monitoring done by Zabbix 6.0 LTS.
occasionally the items stop polling, the monitored interfaces (about 800) have a polling time of 40 seconds. do you know of any mikrotik or Zabbix bugs?
zabbix configuration file:
StartPollers=100
PS:
all snmp requests from the whole network (about 2000 hosts) transit from this router.
occasionally the items stop polling, the monitored interfaces (about 800) have a polling time of 40 seconds. do you know of any mikrotik or Zabbix bugs?
this one is a classic snmp problem.
and generally, any polled devices - in their normal operating condition - will have no problem replying snmp traps.
so the question mark most of the time lies on the snmp server itself.
check its cpu, ram and disk space (tune your memory cache).
provide enough bandwidth so that snmp trap won’t timed out.
40 second is too short for polling, it will saturated your network bandwidth, and could lead in timed out.
don’t forget to check its log.
btw, are those 2000 devies with 800 interfaces each?
1’st , just to clarify - The issue you are encountering is not a problem with any Mikrotik devices .
I use a combination of Zabbix and LibreNMS and WhatsUp-Gold NMS ( Network Monitoring System’s ) and Cacti to monitor thousands of devices in all of the networks I manage. — Each NMS has it’s strengths and weakneses.
Zabbix ; is great for performing ICMP pings to devices and the ability to draw network maps ( of your networks ) is great. I encounter similar problems with Zabbix ( like what you are stating in this Mikrotik forum post ) when I start adding hundreds to thousands of SNMP checks to my devices ( including hundreds of Mikrotik devices ). IMO , Zabbix main weakness is the VPS ( values process per second ) can jump to 400+ VPS , which then makes Zabbix almost unusable because the web interface becomes almost non-responsive. Soooo, I reconfigured my Zabbix NMS to only perform ICMP Ping tests and I also use Zabbix maps for my entire network. — You may want to look in the Zabbix forums to find possible answers to your issues.
LibreNMS ; is great for SNMP - however the ability to draw network maps requires a 3’rd party plug-in ( IMO ; it sucks ).
I would like to suggest that you take a look at the Mikrotik Dude NMS system. It’s works OK for most IPv4 networks ( I don’t know if it supports IPv6 yet ).
So , the issue you are encountering is not Mikrotik related - your issue is your Zabbix NMS system and how you have it configured.
