    Zabbix 2.2 proxy not syncing SNMP? BUG? ver2 fine

    Hi,

    Using:

    Ubuntu 12.04LTS 64bit
    Zabbix 2.2
    SNMPv2c

    No firewall – test system

    My Setup:

    88.x.x.x Server >>> OpenVPN 10.8.0.1 to 10.8.0.2 >>>> 192.168.1.122 Proxy >>>> 192.168.0.1 (ADSL Gateway)


    I want to get the following snmp OID (1.3.6.1.2.1.2.2.1.2.3)value from 192.168.0.1


    Item details:

    Name Triggers Key Interval History Trends Type Applications Status Error
    ifDesc ifDesc 10 90 SNMPv2 agent Enabled


    zabbix@RankSZabProxy ~ $ sudo snmpwalk -v 2c -c obsit 192.168.0.1 1.3.6.1.2.1.2.2.1.2.3
    iso.3.6.1.2.1.2.2.1.2.3 = STRING: "ppp"


    Want to get SNMP value from remote site via proxy. It all appears to work up to and including putting the values into the sqlite database by the proxy but no data sent (via JSON??) to the server


    On the proxy log – SNMP values data is entered into sqlite as expected:


    zabbix@RankSZabProxy ~ $ tail -f /tmp/zabbix_proxy.log | grep ppp
    insert into proxy_history (itemid,clock,ns,value) values (23400,1385334510,408793222,'ppp');


    This in confirmed by viewing sqlite3


    Sqlite>select * from proxy_history;
    6395|23442|1385333912|0||0|3|0|171610825|0
    6396|23402|1385333912|0||0|7139|0|176332656|0
    6397|23400|1385333911|0||0|ppp|0|154647112|0
    6398|23403|1385333914|0||0|10000000|0|624570300|0
    Sqlite>


    I don`t know how zabbix proxy sends (syncs) data I guess JSON based? Anyway ps aux gives the following:


    zabbix 8769 0.0 0.4 41964 1928 ? S 23:27 0:00 /usr/sbin/zabbix_proxy: history syncer #1 [synced 0 items in 0.000516 sec, idle 5 sec]
    zabbix 8770 0.0 0.4 41964 1928 ? S 23:27 0:00 /usr/sbin/zabbix_proxy: history syncer #2 [synced 0 items in 0.000310 sec, idle 5 sec]
    zabbix 8771 0.0 0.4 41964 1932 ? S 23:27 0:00 /usr/sbin/zabbix_proxy: history syncer #3 [synced 0 items in 0.004927 sec, idle 5 sec]
    zabbix 8772 0.0 0.4 41964 1928 ? S 23:27 0:00 /usr/sbin/zabbix_proxy: history syncer #4 [synced 1 items in 0.025156 sec, idle 5 sec]




    Whats interesting is I am only requesting one item and the last line suggests this wasy successful. As in its was synced?

    itemid:23469



    Using chive on the zabbix server and SQL statement: SELECT * FROM `history_log` `t` WHERE `itemid` LIKE '23469' LIMIT 0, 20

    I get: An empty resultset has been returned.

    Same for history, history_text etc and more importantly history_str

    This appears to confirm no data getting through to server.

    When I try to compare syncs:

    Only proxy shows item syncing - 2212:20131125:002150.103 history syncer #4 [synced 1 items in 0.009158 sec, idle 5 sec]


    Can anyone help? Pretty Please! Version 2 fine.

      Solved

      I noticed on the open VPN logs that I was having synchronisation issues in relation to TLS (TLS Error: local/remote TLS keys are out of sync.

      I switched from UDP to TCP (keeps it in sync) and the data is now successfully being transferred from the zabbix proxy to the zabbix server. SOLVED.
