Help on monitoring SNMP variables type IpAddress

[gabin]

Hello,
I'm using zabbix to monitor a few Cisco routers. On a couple of them I want to check routes stability so I want to monitor SNMP variable
.iso.org.dod.internet.mgmt.mib-2.ip.ipRoutingTable.ipRouteEntry.ipRouteNextHop

I have trouble configuring a trigger for when the IpAddress in "ipRouteNextHop" changes.

Please help

Greetings,

I'm using zabbix to monitor a few Cisco routers. On a couple of them I want to check routes stability so I want to monitor SNMP variable
.iso.org.dod.internet.mgmt.mib-2.ip.ipRoutingTable.ipRouteEntry.ipRouteNextHop

For something like that, I would suggest trying something like the following trigger;

{ROUTER:.iso.org.dod.internet.mgmt.mib-2.ip.ipRoutingTable.ipRouteEntry.ipRouteNextHop.diff(0)}<0

Another option would be to translate the MIB to it's numeric syntax to try to shorten it a bit.

Note that the key can be any unique string for SNMP item. It makes little sense to use long numeric or string OIDs for the key.

I configured the trigger and now i get the following messages in the server log

2145:20070321:115131 Parameter [1.3.6.1.2.1.4.21.1.7.10.201.0.0] is not supported by agent on host [router_1.19] Old status [0]
2145:20070321:115131 Cannot store SNMP string value (ASN_IPADDRESS) in item having numeric type

i tried to config the type as integer,float,text and it didn't work
i also checked the snmp variable and it works:

[root@netmon root]# snmpget -Os -c *** -v 2c 10.254.1.19 1.3.6.1.2.1.4.21.1.7.10.201.0.0
ipRouteNextHop.10.201.0.0 = IpAddress: 192.168.250.2

[Alexei]

Please try to configure this item as a string.

after setting type "char" and setting trigger
{ROUTER:.iso.org.dod.internet.mgmt.mib-2.ip.ipRoutingTable.ipRouteEntry.ipRouteNextHop.di ff(0)}#0
the trigger activates when route changes.

Thank you
