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

[vera]

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?

I've got exactly the same error. When I do snmpget I see all the values, in the rrdfiles there are only NaN values. Linux/windows devices monitoring are working fine.

When I do snmpget I see all the values, in the rrdfiles there are only NaN values.

The question is though, are the OIDs which returned data the same ones Cacti is polling? I'm betting no.

How do I verify the OID cacti is polling?

How do I verify the OID cacti is polling?

Turn the polling level in cacti to debug (Settings | Polling level) for one cycle, wait for Cacti to run, and paste the output of the actual log file (<webroot>/cacti/log/cacti.log). If it contains WEBLOG entries, then don't bother posting since they just clutter up the log. Turn off WEBEVENTS logging and try again.

Thanks for the info. Here's the log file. Like others users I'm able to do snmwalk and get info on the router. I cleared the cacti log before running the next cycle in debug mode.

send me one screen shot.

A Screen shoot of Cacti?

laarocho: It seems most of your hosts aren't responding to the UDP pings. Try changing it to ICMP.

CACTID: Poller[0] Host[2] PING Result: UDP: Ping timed out
CACTID: Poller[0] Host[2] SNMP Result: SNMP not performed due to setting or ping result

Ignore Madhumohan, he's just posting uselessly in all posts.

[laarocho]

Thanks for the info. I'll check it out and let you know.

BTW How can I publish my Cacti Install to world just like the one shows on the Cacti website. I already had a guest user that only views the graphs tabs and graphs for that site. But I don't want them to use UNAME or UPASS.

Again Thanks,

LA

Make the default file for your /cacti/ website graph_view.php instead of index.php. If you left the Guest user account enabled, there is no password needed.

[laarocho]

Thanks again!!

And yes I changed the UDP ping to ICMP and now at least the graphs are showing, no data available yet.

Back again ....
But unfortunately with bad bad news !
Still have the same problem , my routers don't work anymore and can't know why ....
I re-index them each time I can,
I got SNMP info with snmpwalk.
But graph aren't drawn, even if the picture is present,
Can someone help me please???

Sims: Anytime cacti is returning errors or warnings in the log file you must change the logging to debugging to see really what is going on. But it seems the OID(s) cacti is trying to use are invalid. Host 49 and 50 are your two routers? What are the OIDs which its trying to unsucessfully poll? Are you able to manually poll those OIDs with snmpwalk?

That's what I did...it is a debug log, but I cut it cause it was too large , I can post it entirely (see attached file) I have disable all my other devices to make it clearer....

Oids that I trying to poll is In/out bits and Errors/discard

I did snmpwalk for this :

Code: Select all

And it return an integer from .1 to .6

Y=1 to 6

IF-MIB::ifindex.Y = INTEGER Y

Please read the last entry in my FAQ on how you know debugging mode is enabled. What you posted might be debugging information, but not what we're after. You want to see cacti trying to poll OIDs and updating rrd files.
