Zabbix 3.0 - Dell PowerConnect Template issues

[greavette]

Hello,

I've been using the Dell PowerConnect templates in Zabbix 2.2 without issue for a few months but now that Zabbix 3.0 is out I'm eager to move to the new platform. I've install CentOS 7 as my Base O/S and successfully install Zabbix 3.0 on CentOS 7.

First issue I found was that value map 'host status' won't work any longer. I was able to solve the import by modifying the Dell PowerConnect template to use Host availability instead.

Second issue has not been easy to solve. In Zabbix 2.2 I imported all 3 PowerConnect templates and was quickly receiving updates from my two Dell PowerConnect 5548 in Zabbix 2.2 (all 96 ports).

In Zabbix 3.0 I'm not receiving all the information I used too. Only one of my PowerConnect switches is displayed and I receive no interface traffic data in Zabbix 3.0?

• I've made sure my Dell PowerConnect switch is pointed to my Zabbix Server. ( can see some data coming into Zabbix 3.0 but not all).
• I've ensured that bulk import was not selected in my hosts file.
• I've installed ruby, rubygem and snmp on CentOS 7. I can successfully walk my switches with snmpwalk. if.speed doesn't work for me though...I get an error in rubygems "/usr/share/rubygems/rubygems/cor_ext/kernel_require.rb:55:in `requuire': cannot load such file -- snmp (LoadError). I've added the following macros: {$INTF_REGEXP} (1/0/) {$SNMP_COMMUNITY} public

Any advice you can provide on what needs to change in these PowerConnect Templates to get them to work in Zabbix 3.0?

Thank you.

I use only the INTERFACE template, and I need to change the tag for ifName: the new value is:

discovery[{#SNMPVALUE},.1.3.6.1.2.1.31.1.1.1.1]

For me the if.speed script don't work, but I use only 5424 switch and I enter a fix speed in template.

I rewrite the IF-MIB::ifInOctets.{#SNMPINDEX} to IF-MIB::ifHCInOctets.{#SNMPINDEX} and for Out to IF-MIB::ifHCOutOctets.{#SNMPINDEX} because in case of huge traffic, the graph is incorrect.

Thank you akoscomp for your comments. I'd like to confirm a few things with you please.

Regarding the ifName update. I currently have on my Discovery Rule for Name=Network Interfaces on my PowerConnect Interfaces Template the following: SNMP OID = .1.3.6.1.2.1.31.1.1.1.1 SNMP community = {$SNMP_COMMUNITY}

Is your comment saying to replace $SNMP_COMMUNITY with #SNMPVALUE instead?

Secondly...where do I update the: IF-MIB::ifInOctets.{#SNMPINDEX} to IF-MIB::ifHCInOctets.{#SNMPINDEX} and IF-MIB::ifoutOctets.{#SNMPINDEX} to IF-MIB::ifHCOutOctets.{#SNMPINDEX}

My PowerConnect Template that I've downloaded from jjmartres doesn't have graphing for interfaces from what I can see?

Thank you for your assistance and any help you can provide me.

Change the SNMP OID = discovery[{#SNMPVALUE},.1.3.6.1.2.1.31.1.1.1.1] Leave SNMP community intact. You can update in Item Prototypes Incoming and Outgoing traffic, change the SNMP OID to: IF-MIB::ifHCInOctets.{#SNMPINDEX} and IF-MIB::ifHCOutOctets.{#SNMPINDEX}

If you have huge traffic on interface, the graph isn't correct. Try to generate 1 Gbps traffic for 5 minutes on one of the interfaces, and you can see, that in graph the interface usage remain under 500 Mbps. This happens because the IF-MIB::ifOutOctets is only a 32 bit integer value, and can store only 4 GB traffic information, but the zabbix read this data only at 60 seconds, and if you copy with 1 Gbps you can reach this limit in 20 seconds, this means, that your graph in optimal condition display only 30% of real traffic or in worst case random data. If you use 100 Mbps switch, this is not a very huge problem. If use IF-MIB::ifHCOutOctets the traffic I think is represented on 64 integer.

My template version: zbx-dell-powerconnect-interfaces.xml.txt

I use with PowerConnect 5424 switch. I remove some parts, that don't work with this switch.
