Hi Amolari and thanks for your reply.

Unfortunately it does not work either 😞

In the custom MIB config file (/config/snmp/custom_mib.tcl) if I return the status of command 

[catch {exec /bin/bash /shared/count_slow_transac.sh} result]
I am getting '1' (expecting '0' => no error)

My interpretation of this '1' output is that the snmp daemon is unable to run 

exec /bin/bash /shared/count_slow_transac.sh
command when getting polled against the custom OID.

But I don't understand why it cannot issue the command... 

ps aux
command shows that snmpd is running under root account so it cannot be a permission issue.
