snmp string to float conversion

[Alexei]

Just updated zabbix to v1.6.4 - The same problem.

Please double check you are running 1.6.4...

Updated to 1.6.4.

Quoted number strings converted normally.

Thanks

I'm positive
- Installed 1.6.4. Restart
- Checked graphs - no data.
- Applied patch, installed again.
- Works fine.

Fix?

I did a quick review of the code in to see how it was fixed, and I could not identify any code that deals with this condition.

Has anyone updated to the latest version and seen it work?

I'm having a similar problem, while running 1.6.4...

But there is a twist... My string has both numbers and text in it, and I need to find a way to strip the number and save it as float.

My OID comes back like this:

SNMPv2-SMI::enterprises.161.19.3.2.2.8.0 = STRING: "-73 dBm"

How can I strip that down to the number? I don't mind loosing the negative sign, as I'm needing the number, not the sign... I won't get positive values, so I'm needing to simply graph the trend. What can I do to extract the value from this string?

Well, I solved my problem with an external command.

I used snmpwalk to create a one-line script that probes the device, then used awk and sed to carve up the output until I had the bare numeric value.

Then I ran that as an external check, and it works great!

/usr/bin/snmpwalk -v 2c -c public $1 .1.3.6.1.4.1.161.19.3.2.2.8.0 |awk {print'$4'} |sed 's/"-//g'
