String of bits - how to evaluate a single bit?

[sovr]

Hi everyboody,
I'm using Zabbix 1.8.13 and I'm monitoring an SNMP host which returns its status as a sting of bits in which each bit carries information.

I'd like to set triggers according to the status of each bit.

E.g. strings received "01100010"

trigger 1: if first bit = 1 then "memory fault"
trigger 2: if second bit = 1 then "processor load too high"
etc...

could anyone please suggest how to?

I made some Google search and found not much on it, sorry if this issue has been already discussed.

Thanks in advance,
sovr

Is the returned value a character string or an unsigned binary ?

[sovr]

It's a character string.

I haven't got the chance of doing this myself but I would give it a try like this :
- create a character type SNMP item for the desired OID
- create regular expressions to match the position for each one of the relevant bit (the 2nd, the 3rd etc.)
- create a trigger using the regexp function that will test the presence of character 1 in the position dictated by the regular expression you build in previous step

it works great thank you!

Unfortunately, I found out that the SNMP host actually doesn't return its status as string of bits, but as a decimal coded integer!

Hard to find which bits are 'up' in such integer...any idea?
Since it's a different topic, I'll open a new thread.

Thanks a lot anyway.
