[Solved] Device OpenBSD 3.9 and SNMP V3

[rodolphedj]

I have enable debuging.

05/04/2007 05:46:54 PM - CMDPHP: Poller[0] Host[18] DS[208] SNMP: v3: 10.33.0.6, dsname: traffic_in, oid: .1.3.6.1.2.1.2.2.1.10.2, output: U

Do you understand the problem ?


The snmpwalk in line command return :
#snmpwalk -v3 -u myuser -l authNoPriv -A ***** 10.33.0.6 .1.3.6.1.2.1.2.2.1.16.2
>IF-MIB::ifOutOctets.2 = Counter32: 100074018

[rodolphedj]

one error found :

If I use the template "Unix - Processes", there is not warning.
Samething for template "Unix - Load Average"

It is false. Data from server Cacti (perhaps bug)

Nobody use here OpenBSD like device for monitoring ?

[gandalf]

The UNIX type templates only work for the local host. They use scripts against local ressources
Reinhard

[rodolphedj]

Ok, Thanks for this details.
But I didn't understand the reason, why openBSD can not monitoring ??

[gandalf]

Have a look at those scripts. Find them at ./scripts. You will see some simple shell commands. Try to execute them at command line. I suspect they will fail. That's why cacti can't retrieve data. If you replace those shell commands by the correct OpenBSD stuff, it will start to work.
Personally, I would stick to the SNMP based companions. They are more universal

I didn't understand.

And by snmpwalk result is done.

[gandalf]

It is possible to graph those values using another approach. Apply the "ucd/net Host Template" to that host and use the new Graph Templates associated with your target (This assumes, you've snmpd up and running on the target which is localhost in this case).
Reinhard

[rodolphedj]

are you an idea why this templates :
netsnmp_memory_usage
http://forums.cacti.net/viewtopic.php?t ... mory_usage
-> perfect result graph by snmp !

and "WARNING: Result from SNMP not valid. Partial Result:" with traffic templates the from the Data Query [SNMP - Interface Statistics] on Cacti ?

[gandalf]

Please verify that php-snmp is installed. Restart httpd, then. Select "Verbose Query" from the device afterwards

[rodolphedj]

Becarful, with all my other devices i can obtain graphic of traffic.

[rodolphedj]

Only for developer :
1 - on line command
/usr/bin/snmpget -O vt -v3 -t 20 -r 1 10.33.0.6:161 -u ********* -l authNoPriv -a MD5 -A ************************* .1.3.6.1.2.1.2.2.1.10.2
Counter32: 558750468

2 - code program (lib/snmp.php)
$snmp_value = @snmp3_get("$hostname:$port", $username, "authNoPriv", "MD5", $password, "", "", $oid, ($timeout * 1000), $retries);
work with some device, but not OpenBSD


I didn't understand the problem ???

[rodolphedj]

3 - on test.php

code result OK :

<?php

$string = @snmp3_get("10.33.0.6:161", ********, "authNoPriv", "MD5", ***********, "", "", ".1.3.6.1.2.1.2.2.1.16.2", 1000, 2);

echo $string;

?>

[rodolphedj]

solution temporary good...

file cacti/lib/snmp.php
line 65

$snmp_value = @snmp3_get("$hostname:$port", $username, "authNoPriv", "MD5", $password, "", "", "$oid", ($timeout * 1000), $retries);


strange : sometimes when i modify code (hard modify ) I need restart apache...

[rodolphedj]

it is not the best solution...

After, I am some problem with other devices....

Hi

can't you use SNMP v2c with :

• user / password
• IP restriction
• non trivial community name

?
