SNMP down - but cacti can see?

msmartinwsx · Post by **msmartinwsx** » Tue May 10, 2005 5:17 am

Hello.

Ive just upgraded to the latest version and everything is working fine, however, one thing is not.

I have the host down detection using SNMP for all hosts and all bar two work.

These two are ADSL routers (albeit different vendors, using the same underlying software).

Cacti shows;

SNMP Information
System: U.S. Robotics Software Version 1406_060404-2.14L.01A
Uptime: 0
Hostname: ext-gw
--
SNMP Information
System: Broadcom Bcm963xx Software Version 2.18L.01
Uptime: 0
Hostname: ext-gw

It seems these hosts do not count uptime and that is the only thing I can think of that is causing the problems.

Cacti lists all the interfaces (pppoe/pppoa/wlan/eth etc) and will allow me to create graphs - it just seems that as it is showing the device as down - no data is collected.

Any help would be great!

Matt

Can you post an output of the following query against both ADSL devices:

Code: Select all

snmpwalk -v 1 -c <snmp community> <hostname> .1.3.6.1.2.1.1

I'm curious if it is responding at all for uptime, or if it's just giving a 0.

Hi;

The reply as below (same on both bar contact, location etc)

[root@pingu root]# snmpwalk -v 1 -c community ip .1.3.6.1.2.1.1
SNMPv2-MIB::sysDescr.0 = STRING: U.S. Robotics Software Version 1406_060404-2.14L.01A
SNMPv2-MIB::sysObjectID.0 = OID: SNMPv2-SMI::enterprises.4413.2.10
SNMPv2-MIB::sysUpTime.0 = Timeticks: (0) 0:00:00.00
SNMPv2-MIB::sysContact.0 = STRING: MY NAME HERE
SNMPv2-MIB::sysName.0 = STRING: ext-gw
SNMPv2-MIB::sysLocation.0 = STRING: MY LOCATION HERE
SNMPv2-MIB::sysServices.0 = INTEGER: 72

Thanks

Matt

More patches for poorly written agents (maybe). The vendor should correct their MIB/OID.

True. However, as per my first post - its not tied to a particular vendor - they seems to use the same underlying (linux based) operating system - and then they just rename.

Is there anyway to temporarily get it to SNMP these devices?

I dont want to have to use MRTG
