Can not add SNMP interface on zabbix 5.0 server on RHEL 7.0

[rajsolanki]

Hi

I m not able to add SNMP interface on ZABBIX 5.0 server on RHEL 7.0


Red Hat Enterprise Linux Server release 7.8 (Maipo)

I have tried all browsers , private browsing mode , localhost , public IP DNS , used public community , used macro all sorts of things i tried.




As soon as i hit update i get

The connection was reset

The connection to the server was reset while the page was loading.

The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer’s network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.


and in http log

[proxy_fcgi:error] [pid 117232] (70007)The timeout specified has expired: [client XX.XX.XX.XX:63554] AH01075: Error dispatching request to :, referer: http://XXXXXXXXX/zabbix/hosts.php?fo...e&hostid=10084

This is bit frustrating as there is no error any where . how does one make this server as snmp trap receiver ?

[rajsolanki]

my snmp walk and snmpget works like charm.

i also have zabbix configured for snmp trapper

ps ax | grep snmp
5447 pts/0 S+ 0:00 grep --color=auto snmp
10303 ? Ss 0:22 /usr/sbin/snmpd -LS0-6d -f
10845 ? Ss 0:38 /usr/sbin/snmptrapd -A -Lf /var/log/snmptrapd.log -p /var/run/snmptrapd.pid -f
120730 ? S 0:00 /usr/sbin/zabbix_server: snmp trapper [processed data in 0.000015 sec, idle 1 sec]

No SNMP expert, but is there a reason why SNMP community is empty? Have you tried with "public"?

[rajsolanki]

yes i have tried everything. i just shared an image by hiding my community.

[rajsolanki]

any one willing to help ?

Pls show “grep -A 11 Start /you-log-path/zabbix_server.log”

if you want i can demo you on screen share

[rajsolanki]

or if you want to see you can see here from video uploaded by zabbix team (i guess ) https://www.youtube.com/watch?v=fVK2YWdTalQ for me step at min 20 sec 10 is failing . i have tried local host public ip all sort of combination

This may sound like a weird question, but humor me please.

Has your current zabbix database been through upgrades several times, meaning have you been using Zabbix for a while and upgraded from perhaps 3.0 or earlier?

If the answer to the last question was yes, then I have a follow-up question: Did you need to ALTER the DEFAULT COLLATION for your DB/tables/columns as part of any of the upgrades?

[rajsolanki]

this is a fresh install. we are trying to replace an existing monitoring tool with zabbix. so as first step is to install , configure to receive SNMP traps.

[rajsolanki]

anything i should try to figure this ?
