b0fh,

You have the same problem that I had. This seems to be an 0.8.5 upgrade bug.

Please follow this link for the solution:

Yesterday I had to restart squid because of an update. It might be that squid was down at the moment when cacti tried reading out values via snmp.
The whole thing gave a pretty ugly effect: At the restart-time, I have a very large value in graphs "Client request rate", "Squid CPU usage", "DNS Statistics", "Squid error rate" and "page faults" (all about 10M (Megs)...). Anything you could update about this?

I updated to rrdtool 1.0.47, now I get very "fat" lines in "client request rate" and "DNS statistics". (Seems to be LINE3 or so)... Whos issue is this?

Well, I know that squidstats is made for 0.8.5, but I even tried to use it with the current release. XML Import was ok.
But then I genereated the first host using the template "WebCache - Squid Server (SNMP)", SNMP Version set to 2 (even tried with version 1) and got

    Warning: Variable passed to each() is not an array or object in /usr/local/cacti-0.8.6b/lib/data_query.php on line 464

    Warning: Variable passed to each() is not an array or object in /usr/local/cacti-0.8.6b/lib/data_query.php on line 464

    Warning: Cannot modify header information - headers already sent by (output started at /usr/local/cacti-0.8.6b/lib/data_query.php:464) in /usr/local/cacti-0.8.6b/host.php on line 121

SNMP is working for the requested host. But the data query "WebCache - Squid Statistics - Core" does not show any item. Verbose query results in

    Warning: Variable passed to each() is not an array or object in /usr/local/cacti-0.8.6b/lib/data_query.php on line 464

    Warning: Cannot modify header information - headers already sent by (output started at /usr/local/cacti-0.8.6b/lib/data_query.php:464) in /usr/local/cacti-0.8.6b/host.php on line 75


Thnx for any help

Ok, I think I'm on the way now . Missed something from the README. Have to reconfigure my squid, will last a while.
I'll post the results for cacti-0.8.6b with patches applied.

Has anyone gotten this to work with 0.8.6b?

I set my poll method to ping only, to try and get around the snmp errors, but I'm still getting host down, and no rrd files are getting created. The squid specific snmp queries ARE working, though.

Yes, it's now working for me.

But as long as you get ping problems (ICMP or SNMP), cacti o.8.6b won't even ask your squid to get the stats.
Try setting "Configuration Settings" -> "poller specific logging" -> "poller logging level" to debug and have a look at your cacti.log file. You will see, that ping test fails and nothing more happening, I suppose.

As far as I know there will be a change in 0.8.7 to suppress ping probing.
Perhaps, there is a firewall in between, blocking the ping probe?

Nope, both machines are on the same subnet with nothing more than a switch and a patch panel between them. I'll check the log output the next time I can drag myself away from World of Warcraft.

Ended up restraining myself and testing it.

Set log level to debug, and from what I can tell, it's not even attempting the ping. There're no messages at all for that host.

Still showing as down, despite successful pings. Maybe I can trick squid into supplying the information that cacti seems to want.

The same problem
Importing XML went fine, uploading those 2 XML was OK.
Every graph creation process went without problems.
But graphs doesn't show, even rrd files are not created. Looked into pooler_item mysql table - nothing is shown about squid
What do we miss here?

Update:
Log file states:
Code:

 01/26/2005 04:10:43 AM - SYSTEM STATS: Time: 41.3046 s, Method: cmd.php, Processes: 1, Threads: N/A, Hosts: 8, Hosts/Process: 8

Poller cache states 7 hosts and nothing about squid box but SNMP cache clearly states presece of squid.
Code:

 Host: ---(squid), SNMP Query: WebCache - Squid Statistics - Core
Index: 0, Field Name: versionID, Field Value: 2.5.STABLE5
OID: .1.3.6.1.4.1.3495.1.2.3.0
Host: ---(squid), SNMP Query: WebCache - Squid Statistics - Median Based
Index: 1, Field Name: medianTime, Field Value: 1
OID: .1.3.6.1.4.1.3495.1.3.2.2.1.1.1
Host: ---(squid), SNMP Query: WebCache - Squid Statistics - Median Based
Index: 5, Field Name: medianTime, Field Value: 5
OID: .1.3.6.1.4.1.3495.1.3.2.2.1.1.5
Host: ---(squid), SNMP Query: WebCache - Squid Statistics - Median Based
Index: 60, Field Name: medianTime, Field Value: 60
OID: .1.3.6.1.4.1.3495.1.3.2.2.1.1.60


As we can see, cmd.php wants to make stats for 8 hosts but poller.php received only 7 of them.

Someone in another thread pointed out that snmpd has a proxy.

So, if you have snmpd running on the same box as you have squid (and you do, right?)... you can add:

proxy -v 1 -c public localhost:3401 .1.3.6.1.4.1.3495.1

(or whatever your community string is) to your snmpd.conf (anywhere in the file is fine)...

And then just add the squidstats queries to the host, instead of creating a seperate host entry.

And it works.

Ok, I read that this is "0.8.5 only", but did any of you manage to get it running under 0.8.6c? I keep getting an "SNMP error" in my squid-device list...

Yes.

Like I posted in the post before yours. Add:

Code:

proxy -v 1 -c public localhost:3401 .1.3.6.1.4.1.3495.1


to your snmpd.conf

Then, instead of creating a seperate squid device in cacti, just add the squid data queries to your likely already monitored host, and create the graphs from there.

Hm, I did that, but I keep getting "SNMP error" and NaN in my Graphs... Do I need to enable proxing in snmp? Any other configuration needed?
