My Cacti works good but no graph drawn with my CISCO routers

Sims · Post by **Sims** » Fri Apr 21, 2006 9:05 am

Hi there !
Now my cacti seems to be all right , exept the graphs for CISCO Routers,
Indeed I can use SNMP Host for all my switch (HP2626 2650...) But not on any

of my CISCO Router....
I tried CISCO template too , but nothing

RRDFiles are created and the picture appears , but not any graph are
drawn....

Poller in low mode using cmd:

Code: Select all

04/21/2006 03:25:38 PM - RECACHE STATS: RecacheTime:10.2181

And here is the debug mode on attachment (a bit long

sorry)

Recaching is fine, that simply means cactid detected a change in interface / uptime count and reindexed it.

Which devices in that log file are you Cisco devices?
Are the cisco devices returning any snmp data? If not, there is your problem...

Here is the code with only my CISCO device the 39/41/42
And I can get SNMP with Getif so ?!?

so... turn the logging level in cacti to debug for one polling cycle to reveal the OIDs cacti is trying to poll, which don't exist. Without looking, maybe try re-indexing your snmp interface query for Host[41].

Sims · Post by **Sims** » Thu Apr 27, 2006 5:09 am

I tried to re index my entry for host 41, but no success, the host come from down to up so I test it on only one of my CISCO device.
The 39, and dont know why now it works for this host only !
Here is the debug mode for my Host 39 before it works (see attachement)
When I try to do the same with my other device , no success , can't know why , but SNMP is polling for sure .

BSOD2600 · Post by **BSOD2600** » Thu Apr 27, 2006 10:39 am

Great host 39 works....

Does cacti consider the other devices up?

Sims · Post by **Sims** » Fri Apr 28, 2006 9:59 am

Yep up , and SNMP information are OK when I add the devices , but graph arent drawing

Still looking after the problem ...

BSOD2600 · Post by **BSOD2600** » Fri Apr 28, 2006 11:09 am

So post a debug polling cycle from Host[41]. You should immediately notice all the OIDs which are invalid it's trying to poll.

Sims · Post by **Sims** » Tue May 02, 2006 2:48 am

Here is a debug polling of the host 43...
That was the 41 but I have modify it , and now it is the 43...
Still the same problems...

BSOD2600 · Post by **BSOD2600** » Tue May 02, 2006 10:19 am

Are you able to run snmpwalk from the cacti server against host 43?

Please post a polling cycle containing output from host 43.

Sims · Post by **Sims** » Wed May 03, 2006 10:59 am

Here are the polling , on low mode and debug again ....
Thanks again for your help !
And for SNMPWalk I have something that could interest you I think....

After entering that :

E:\usr\bin>snmpwalk 10.x.y.z

Code: Select all

snmpwalk: No securityName specified

the same with the "-c communityname"

Isn't snmpwalk only for SNMP v3???

For myself I'll see if there is security name or not , cause I thunk this was only on v3 ...

BSOD2600 · Post by **BSOD2600** » Wed May 03, 2006 11:42 am

snmpwalk works with any version. Try:

Code: Select all

snmpwalk -v 2c -c public 10.56.8.254 .1.3.6.1.2.1.2

As you can see from the debug output, cacti is trying to poll all of those OIDs which the cisco device is saying is invalid. Possibly you need to reindex the snmp interface errors query (click the green circle) or maybe the router doesn't support that MIB. The snmpwalk will reveal all.

Sims · Post by **Sims** » Thu May 04, 2006 4:11 am

oOo

BSOD2600,
I think you'll can save me !!!!!
I don't really know what does all that mean , but I have answers for my host 254 with

Code: Select all

snmpwalk -v 2c -c public 10.x.y.254 .1.3.6.1.2.1.2

I try to understant all that it means , but cannot analyse this ^^

So waiting for your excelent analyse !!!
Thanks by advance , I reindex my host to see if it works

Sims · Post by **Sims** » Fri May 12, 2006 2:40 am

Re index doesn't work

I am still looking for something that doesn't works well , but for me everything should work , any advice ?

BSOD2600 · Post by **BSOD2600** » Fri May 12, 2006 11:20 am

Each time you change an interface up/down on the router, Cacti needs to be reindexed. Possibly look into running poller_reindex_hosts.php nightly to accomplish this.

Looking in the cacti log file after debugging cycle, are the OIDs it's trying to poll which are invalid, different than before?

My Cacti works good but no graph drawn with my CISCO routers
