string to integer without script

[Jason.S]

Hello,

We have been fighting a MONSTER high load on our server, and to kill off some scripts, I need a way to do a string to integer.

[Jason.S]

Anyone?

Hello,

What do you want to achieve? Is this Cacti-related?

Hello sir,

It is cacti related. Our SU-ID-1D radios will give their RSSI in a octet string format. I need a way to take the string value and convert it to a number so that it can be graphed.


Thank you,
Jason

Hmm, Larry recently fixed a hex conversion issue. Don't know, if octet conversion is in as well. You may want to pm him

Hi All!

I have the same task as Jason have.
My snmp agent tooks data from SHELL script. But snmpwalk shows me that this data is represented as STRING (see 2.101.12).

Example:
snmpwalk -v2c -c 'comm_name' hostname .1.3.6.1.4.2
2.1.1 = 1
2.2.1 = "some text"
2.3.1 = "/usr/bin/sh /path/to/script.sh"
2.100.1 = 0
2.101.1 = "text description"
2.101.2 = "12"
2.102.1 = 0
2.103.1 = ""

The question is - is it possible to graph 2.101.12 as it is represented now or there is another way to configure snmpd.conf so snmp agent will send INTEGER data?

Gandalf and other CACTI Guru! I'm looking forward to your response.

Regards,
Pavel

2.101.1 = "text description"
2.101.2 = "12"
2.102.1 = 0
2.103.1 = ""

There is no 2.101.12 in your example. A typo? Cacti does not care about types. Passing a string representation of a number is fine. But Cacti assumes the number to be base10 and not base8 or whatever you may imagine.

Gandalf, thank you!

Yes,it's a typo! I meant 2.101.2 with value "12"
I'll try to graph this OID, however, it's still unsucessfull for me

Please see 2nd link of my sig to see what cacti receives and how it handles the data. Which version of Cacti are you running? Are you using spine?
