Duplicated active agents in network ? Or DB specific configuration/issue |
Comment by DKoshelev [ 2014 Apr 19 ] |
Agents is passive, proxy is passive. There is only one agent on this host. DB configured from default screens. |
Comment by DKoshelev [ 2014 May 23 ] |
This problems was due to low performance. After upgrading hardware on zabbix server all looks fine. |

Closing then. |
Comment by Aleksandrs Saveljevs [ 2014 May 23 ] |
Zabbix should not exhibit buggy behavior if run on an old hardware. Reopening... |

Given the name of item in question ("... RPS" aka "requests per second") I can assume that it was stored as "Change" or "Change per second". And given that proxy was passive I claim that this was fixed in Closing as Duplicate. |
