Graph templates for Squid

[Tolien]

I can't get net-snmp to handle proxying the SNMP requests to Squid.
Running snmpwalk with the community and port to access the Squid proxy directly, I get all the values I'm supposed to get, but accessing the snmpd I get:

:~$ snmpwalk -m /usr/share/squid/mib.txt -v 2c -c community localhost .1.3.6.1.4.1.3495.1
SQUID-MIB::squid = No more variables left in this MIB View (It is past the end of the MIB tree)

Nothing appears in syslog from Squid when I run the snmpwalk, though snmpd does show "Connection from 127.0.0.1".

In snmpd.conf I've got

proxy -m /usr/share/squid/mib.txt -c community -v 1 localhost:3401 .1.3.6.1.4.1.3495.1

Restarting either squid or snmpd doesn't produce any messages in syslog that seem related (more to the point, doesn't produce any messages that aren't there when the snmp config is commented out).

Any suggestions, since I'm stumped.

Hi - I posted this elsewhere, someone posted it in the previous page

---------

You can configure your snmpd.conf file to passthrough snmp queries like ...

proxy -v 1 -c <communityname> <squid_machine>:3401 .1.3.6.1.4.1.3495.1

In my case -

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

Hope this helps.

-P
-------

You have

proxy -m /usr/share/squid/mib.txt -c community -v 1 localhost:3401 .1.3.6.1.4.1.3495.1

Try the one above without the mib.txt (which would be faster anyway)

-P

I also noticed that you are using -v 2c in the snmpwalk... try just -v 1

[Tolien]

Sorry, been away for a few days, hence lack of response.

Dropped the -m /usr/share/squid/mib.txt and tried -v 1 in the snmpwalk. The output I get is now:

~$ snmpwalk -v 1 -c hammondpublic localhost .1.3.6.1.4.1.3495.1
End of MIB

Squid logs still show no SNMP connection is made, but snmpd log shows "Connection from 127.0.0.1".

Hi!

I'm using squid graphs, everything ok, but every day I run by CRON program logrotate for gzip the logs and create new logs. Squid is stop and after new logs is created, Squid is started.

The problem is: Squid Traffic in/out saved is resizing and go to 100 Gbps; DNS statistics is resizing to 15 M queries/second; etc.

Anyone knows how can I resolve this problem?

Thks,

Paulo

hi all,

proxy -v 1 -c <communityname> <squid_machine>:3401 .1.3.6.1.4.1.3495.1

Works perfectly ;

Apparently cactid-0.8.6g wont poll to non standard snmp ports so in Squid's case this is basically a necessity now.

Also saves time not having to alter data templates.

[zeroy]

Can't get this to work.... I added the line in snmpd.conf:

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

but running the Cron job I get:

Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: .1.3.6.1.4.1.3495.1.3.2.1.4

Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: .1.3.6.1.4.1.3495.1.3.2.1.5

Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: .1.3.6.1.4.1.3495.1.3.2.1.1

Strange thing is that running in command line wrks perfect! Help!

[zeroy]

in command line:

snmpget -v 1 -c public localhost:3401 .1.3.6.1.4.1.3495.1
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: SNMPv2-SMI::enterprises.3495.1

This is the same message i am getting when running poller.php

Same problem here. Added the line to our Squid server (RHEL 4 running net-snmp 5.3), and I get the following;

snmpwalk -v 1 -c ##### <host> .1.3.6.1.4.1.3495
SNMPv2-SMI::enterprises.3495 = No Such Object available on this agent at this OID

How comes this is working for some and not others???

[gandalf]

Did you restart snmpd after changing the snmpd.conf?

maybe new version's problem, many things work on 0.8.6g but not work on 0.8.6h, I tried this one and isn't working for me as well, weired.

I got this...

it doesn't even have oid in query, sounds bit crazy..hehe.

Don't know what's wrong, but I found the way to work around, proxy certainly doesn't work for me, so I just import template, then change data template to put oid by myself and put port 3401, finally it's working.

How did you find that lot of OIDs? My squid won't tell me that much (looks like the post of zeroy and is a 2.5 STABLE11).

Yes, I add 11 of them

if you load the mib file that comes with the distribution, it should work. I have attached it as well.
