DDWRT SNMP Zabbix Template

[registration_is_lame]

Hello,

Running Zabbix agentd on ddwrts is possible but a very bad idea I realized after 1 year period, it puts a lot of load on the small router's CPU's and memory and crashes/misbehaves a lot. So I would like to switch to SNMP based monitoring. Did anyone write a template for this?

I have 2 templates now with the router:

Template_Linux_DDWRT, Template_SNMPv1_Device

Linux_DDWRT will not work, since this is only for Zabbix Agent.

Template_SNMPv1_Device will enumerate a lot of attributes such as:

	 	Template_SNMPv1_Device:icmpOutTimeExcds	Triggers (1)	icmpOutTimeExcds	60	7	365	SNMPv1 agent	-	Active	
 
	 	Template_SNMPv1_Device:icmpOutTimestampReps	Triggers (1)	icmpOutTimestampReps	60	7	365	SNMPv1 agent	-	Active	
 
	 	Template_SNMPv1_Device:icmpOutTimestamps	Triggers (1)	icmpOutTimestamps	60	7	365	SNMPv1 agent	-	Active	
 
	
 
	Template_SNMPv1_Device:ifDescr1	Triggers (1)	ifDescr1	60	7		SNMPv1 agent	-	Active	
 
	
 
	Template_SNMPv1_Device:ifDescr2	Triggers (1)	ifDescr2	60	7		SNMPv1 agent	-	Active	
 
	
 
	Template_SNMPv1_Device:ifDescr3	Triggers (1)	ifDescr3	60	7		SNMPv1 agent	-	Active	
 
	
 
	Template_SNMPv1_Device:ifDescr4	Triggers (1)	ifDescr4	60	7		SNMPv1 agent	-	Active	
 
	
 
	Template_SNMPv1_Device:ifDescr5	Triggers (1)	ifDescr5	60	7		SNMPv1 agent	-	Active	
 
	
 
	Template_SNMPv1_Device:ifDescr6	Triggers (1)	ifDescr6	60	7		SNMPv1 agent	-	Active

But with 30 so ifDesc's no way knowing what is what.

Thank you.

DDWRT SNMP monitoring with Zabbix

Hello,

This will not be about using the zabbix agentd on ddwrt ( which although possible and easy, will put a high load on the routers cpu and you can end up with missing data from your graphs like the graph above. )

So I have decided I switch from zabbix_agent to traditional snmp monitoring what ddwrts support.

After reading this 2 articles:

https://www.dd-wrt.com/wiki/index.php/SNMP

http://www.howtogeek.com/141135/it-geek-monitor-network-devices-with-snmp-simple-network-management-protocol/

Zabbix 3.0 with Template_SNMPv1_Device is able to enumerate 207 out of the 479 possible snmp parameters with snmpwalk. It does not mean that these are all useful for example:

HOST-RESOURCES-MIB::hrDeviceID.769 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrDeviceID.1025 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrDeviceID.1026 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrDeviceID.1027 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrDeviceID.1028 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrDeviceID.1029 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrDeviceID.1030 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrDeviceID.1031 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrDeviceID.1032 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrDeviceID.1280 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrDeviceID.3072 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrProcessorFrwID.769 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrNetworkIfIndex.1025 = INTEGER: 1
HOST-RESOURCES-MIB::hrNetworkIfIndex.1026 = INTEGER: 2
HOST-RESOURCES-MIB::hrNetworkIfIndex.1027 = INTEGER: 3
HOST-RESOURCES-MIB::hrNetworkIfIndex.1028 = INTEGER: 4
HOST-RESOURCES-MIB::hrNetworkIfIndex.1029 = INTEGER: 5
HOST-RESOURCES-MIB::hrNetworkIfIndex.1030 = INTEGER: 6
HOST-RESOURCES-MIB::hrNetworkIfIndex.1031 = INTEGER: 7
HOST-RESOURCES-MIB::hrNetworkIfIndex.1032 = INTEGER: 8


With Zabbix these are the items (not all of them is available):

Did anybody succeded identifying which if corresponds to which virtual network interface or even better did anyone wrote a Zabbix template for this?

Once again what I trying to do here has nothing to do with the Template_Linux_DDWRT Zabbix template (which is used in case a zabbix agent is running on the router).

Thank you
