Support for swedish characters 'åäö' when doing a snmp query

[antec42]

Hello all,

I'm having a problem with a custom query that I've created. In the XML-file I have specified an input that will show up as the name in the graph later on.

The query is a snmp index type. I did a normal snmpwalk of the index (like this: snmpwalk -c public -v 2c IPADRESS .1.3.6.1.4.1.13732.1.1.1.1.7) which gives the following result:

SNMPv2-SMI::enterprises.13732.1.1.1.1.7.5051091 = STRING: "GNÖ - 70355 SD"
SNMPv2-SMI::enterprises.13732.1.1.1.1.7.5051092 = STRING: "NRA - 70356 SD"

The index here, of course, is 5051091; 5051092 and so on... The name i wish to have on the graph is the string value.

When I do a "verbose query" however all strings with characters "åäö" in them gets converted to a hex-string and for example show up like this in Cacti:

47:4E:D6:20:2D:

All other strings without 'åäö' is shown correctly...

Clues any one??

First verify that your net-snmp paths are correct in Console->Settings->Paths

Then, edit the include/global.php and set the following line to "false"

Code: Select all

$config["php_snmp_support"] = function_exists("snmpget");

in other words:

Code: Select all

$config["php_snmp_support"] = false

Then rerun the data query, what do you get?

Hi, thanks for the reply...

I tried it but it's still the same. Something within cacti then, perhaps? I forgot to mention that the whole string gets "wasted" with hex-numbers and not only the äåö characters...

Typically, this happens when the MIB file for the vendor does not know what type of string it is. It's interesting that you are experiencing the same behavior even with PHP_SNMP disabled.

Can you goto the console, click on the Cactus and then post the About page. I am interested in the bottom of the page. Also, post the results of the "Verbose Query" when editing the device.

As you can see the last line is the first "remoteName" with 'åäö' and it produces the HEX-string... And yes, I turned PHP-SNMP support on again when I did this query. I've also removed all non-interesting lines with my --- SNIPS ---

No more clues to this problem?
